Advances in language models have opened up endless applications in the social and health sciences. A key to fulfilling this promise is the development of rigorous practices for gathering data used for model training. This research project reports the development of standardized protocols for building databases for self-reported psychological questionnaires that can be used to fine-tune language models. These questionnaires cover a spectrum from childhood experience to altered states of consciousness and beyond. We systematically review the literature on appropriate database-building strategies, use combined data collection techniques, and instill specific criteria into our collection process to help facilitate the research’s computational pipelines on evaluating the relationship between semantics and psychological factor membership. Using a 2D semantic map of the PsycTests database as a reference, we can further evaluate the effectiveness of our protocols by developing quantitative measures to assess comprehensiveness and objectivity in our database building. Our initial explorations involve measuring data variance and density of data distribution. This research provides a general toolkit for building text databases for appropriate and effective model training purposes across various disciplines.

Ethnic/racial minorities often face challenges associated with adjusting to a dominant or new host country. These challenges, known as acculturative stress, include difficulties with behavioral, emotional, and social adaptations, and are linked to adverse outcomes. Understanding the degree to which, for whom, and in what contexts acculturative stress may affect mental health is important in designing culturally-informed interventions. Yet, there are several limitations in the current literature on acculturative stress. First, most studies focus on Latino or Asian ethnic groups or international students/cross-national migrants; it is unclear how acculturative stress is differentially associated with health across populations. Second, most studies have focused on mental health outcomes, whereas other important outcomes (academic, relationship) are neglected. Using records from a large-scale meta-analysis project, we conducted a scoping review of research on acculturative stress to characterize the heterogeneity across studies. We performed literature searches using keywords (e.g., “acculturative stress,” “bicultural stress”) in databases including PsycINFO, and identified 3746 relevant studies. Abstract and full-text screening yielded 681 published and unpublished articles eligible for quantitative analysis. Primary studies were included if they measured acculturation in the context of intercultural adaptation and migration, acculturative stress, and health, academic, and relationship outcomes. We coded and summarized sample characteristics of all articles (e.g., % immigrants, % female/woman, mean age). We will randomly select 50 articles that examine acculturative stress and its associations with mental health, academic, and/or relationship outcomes. We will review and present common outcome measures, instruments assessing acculturative stress, and conclusions. We expect the scoping review to indicate patterns, variability, and gaps in the acculturative stress literature. Results will inform future research on overlooked outcomes and understudied populations, and shed light on necessary basic scientific information (e.g., mediators, modifying conditions) that will support the development of culturally-informed interventions and policies.

Reward-seeking behavior, crucial for survival, is hijacked by various neuropsychiatric disorders, notably substance use disorder. Prior work implicated reward-seeking with the dorsomedial striatum (DMS), a brain structure expressing the endogenous opioid dynorphin (dyn) in 50% of its neurons. Previous studies also linked dyn, signaling through the kappa opioid receptor (KOR), with escalation and reinstatement in drug-seeking, however, the exact mechanisms of dyn-KOR signaling remain unknown. Recent experiments from the Bruchas lab show that supraphysiological release of dyn in the DMS with excitatory optogenetics elicited reward-seeking behavior, demonstrating that dyn-KOR is sufficient for reward-seeking behavior, but not that it is necessary. To provide evidence of necessity, I plan to inhibit dyn-KOR signaling in the DMS by expressing the novel inhibitory optogenetic tool Platynereis dumerilii (PdCO) that we recently showed to be useful for such studies (Wietek et al., Nat Methods, 2024). PdCO is expressed in a target neuronal population and begins inhibiting under 473 nm light. Hence, in this study, PdCO will be injected into the DMS and expressed selectively in dyn neurons. Following recovery, mice will learn a self-administration procedure to study reward-seeking behavior, where sucrose is delivered when mice poke their nose in the correct 1 of 2 holes, with a 5s light cue before reward delivery. Following learning, I will inhibit dyn release in a counterbalanced fashion by activating PdCO using 20 Hz pulsed 473 nm light. I anticipate that inhibiting dyn release would result in reduced sucrose consumption. Finally, I plan to use an extinction learning procedure, where dyn release is inhibited during perceived reward delivery. Here, I hypothesize that inhibition will accelerate extinction learning. By leveraging the specificity of optogenetics on various procedures, this study begins to isolate the exact mechanisms by which dyn-KOR signaling impacts reward-seeking behavior with potential insights for substance use disorder interventions.

This study seeks to explore the perspectives of Latine students at the University of Washington (UW) regarding racial representation within the institution. Do Latine students see their experiences and identities represented and reflected in university life? How do Latine students experience and perceive Latine representation (or lack thereof) in terms of the composition of faculty, student body, and community spaces at UW? This research project aims to uncover the realities, challenges, and promise of support and community on campus. Through interviews with Latine students, faculty, and staff, this inquiry will describe how students find support at UW and navigate their academic environment. To attain a comprehensive understanding, the research utilizes a combination of primary and secondary sources, incorporating interviews with Latine students, staff, and faculty at the UW to capture personalized and nuanced perspectives. By examining the lived experiences and perspectives of individuals directly affected, the study aims to thoroughly examine the complex dynamics at play. Exploring the lived experiences of Latine students, the study will contribute to the discourse on racial representation in academia and its impact on student well-being and academic success. The findings will inform discussions on how institutions can foster an inclusive environment that recognizes and supports the diverse backgrounds of all students. This research project has emerged from ongoing conversation and collaboration with the Washington State Commission on Hispanic Affairs members. This research project will inform the community report that the Commission is preparing.

Alcohol and other substance use are associated with a range of negative physical, mental, and social consequences including blackouts, unintended injuries, involvement in interpersonal violence, and other health problems. Young adults in college are particularly at risk for alcohol and other substance use. While existing research on reduction interventions often emphasized individual responsibilities of those that engage in alcohol and substance use, peer interventions remain an overlooked approach to harm reduction. Bystander interventions have been shown to be effective in preventing and reducing the harm of sexual assaults among college students. However, there is less empirical attention on applying bystander interventions to reduce the negative consequences of substance use. An important first step of understanding how to incorporate bystander interventions to address substance use is to have a reliable and valid measure assessing these behaviors. This study aims to develop and examine the psychometric properties of a new bystander behavior scale specific to substance use. Data came from a large multi-site survey study with 930 college students (Mage = 19.39, 69.6% female, 58.1% White). I will conduct exploratory factor analysis to extract underlying factors that best explain the observed correlations between the items. Next, I will examine convergent and discriminant validity of the scale scores by correlating them with established instruments such as Drinking Refusal Self-Efficacy Questionnaire and Personal Assessment of Responsible Drinker Identity. Individuals who score higher on the bystander behaviors measure are expected to score higher on self-efficacy in resisting alcohol and be more likely to identify as responsible drinkers. Results will provide initial validation data for the bystander behaviors measure and can be used in future research and intervention implementation that address substance use among college students.

Alzheimer's disease (AD) is a neurodegenerative age-related disease characterized by the presence of amyloid-beta aggregates and hyperphosphorylated tau tangles. It has been well documented that cognitive decline and changes in age-related pathways are associated with disease progression. Mitochondria play an important role in degradation of amyloid protein through a mitochondrial protein-mediated quality control system. This pathway can break down with increasing age and lead to the overwhelming presence of amyloid, disrupting normal mitochondrial activity. This damage leads to the formation of more Aβ plaques and neuroinflammation, contributing to the pathogenesis of AD. Mitochondrial regulators may be potential therapeutic drug targets but models are needed to help identify and characterize them. In this regard, an Adeno-Associated-Viral (AAV) vector was used to induce AD protein expression in the brains of old mice. 40 Male and 40 Females mice aged 24 months were infected with either the AAV-AD or AAV-SHAM vector and given 3 months for expression of the proteins to build. Mice were euthanized and brain tissue collected into formalin, with the hippocampus cut into slides for immunohistochemistry (IHC). Data generated from these mice has shown trends in decreased synaptic integrity, increased inflammation and DNA damage associated with expression of the vector proteins. Utilizing the same model, this experiment aims to understand how expression of the AAV-AD proteins may be associated with known roles of mitochondria and characterized pathways in the early stages of AD. IHC was performed using antibodies specific for PITRM1, a mitochondria protein degradation regulator, and PINK1, responsible for mitochondrial-mediated cell death (mitophagy). Imaging software “ImageJ” will be used for quantitative analysis of the stains. This study will help clarify an association between varying levels of AD protein expression and mitochondrial regulation, providing valuable information for enhancing therapies aimed at preventing the progression of early stage AD.

Resilience in Alzheimer's Disease (AD) is defined by the difference between a person's expected and actual rate of cognitive decline given the severity of their disease. However, the mechanisms behind resilience are still unclear and I wanted to see if the anatomy of the brain over the course of AD could offer any clues. To accomplish this, cognitive tests and brain scans were obtained from patient data taken at Harborview Medical Center. Brain tissue atrophy in regions of interest were defined and combined into two measures. The first--biological subtypes--is whether the disease primarily affected the limbic regions or the cortical regions, while the second is left-right asymmetry. I found that resilience correlated with biological subtypes but not asymmetry. This suggests a way for us to predict resilience to better personalize treatment and eventually find ways to increase resilience.

In recent years, organizations have debated whether elements of “white supremacy culture”, including a sense of urgency, may create inequitable environments for people of color. We aimed to empirically investigate whether cultures of urgency in professional settings undermine the recruitment of racially minoritized groups. Undergraduate participants (N = 219) read job advertisements for two jobs: one where urgency culture is highly valued (e.g., “swiftly reset priorities at any given time”) and one with less sense of urgency (e.g., “adjust priorities based on capability”; order counterbalanced). Participants then reported how likely they would be to apply to each job. We hypothesized that individuals from racially minoritized groups will be more likely to apply to lower-urgency jobs over high-urgency jobs. The results show that most participants preferred lower-urgency jobs. However, countering our hypothesis, individuals from racially minoritized groups held more positive attitudes towards high-urgency jobs (e.g., how well they think they'd perform in the job) when compared to white participants. This finding casts doubt on the proposed elements of "white supremacy culture". It urges for more empirical research on how different racially minoritized groups may perceive these elements in work settings. Furthermore, our sample consists mainly of Asian Americans, which does not speak for the experiences of other racially minoritized groups. Our future research will focus on diversifying samples collected.

Neuroscience research relies heavily on cell counting to assess brain injury and evaluate neuroprotective treatments. While manual methods (i.e. hand counting) have been used traditionally, automated programs offer the potential for standardized and error-free data analysis. In the context of studying hypoxic-ischemic encephalopathy (HIE), a prevalent brain injury in infants, we aimed to assess the accuracy of an automated cell counting program in an in vitro slice culture brain injury model of injury and treatment. Code templates from ImageJ/Fiji were taken and modified using ChatGPT, and other snippets were used and modified from online forums like GitHub. The program searches through folders/subfolders for images, converts them into a binary image based on fluorescence threshold data (used to stain cell nuclei), applies the ImageJ function “watershed” that breaks larger groups into smaller groups, runs the “analyze particles” function which outputs a total cell count based on the size and circularity of the cells, and then saves the final image. Fluorescence threshold, cellular size, and circularity values were determined before data collection by adjusting the values to best fit the final image of a random slice. The settings were then kept consistent within studies. Preliminary results show the program’s high accuracy and precision, with consistent results across caffeine and Azithromycin treatments in our in vitro injury model. Despite yielding higher counts than manual methods, the program remained consistent across models. Validating this automated method represents a significant advancement in research methodology. These programs offer standardized data collection, error elimination, and faster analysis compared to manual counting, potentially saving time and resources for labs. Current limitations in our research involve differentiating between healthy and dead or dying cells, which would be an important future step for automated cell counting.

Poor communication within and between teams of health professionals has been shown to lead to errors and negative patient experiences. Daily interprofessional bedside rounds (IBR) in which care team professionals develop and update plans in collaboration with patients and families, are associated with a reduction in these negative outcomes. However, little is known about how IBR and related care outcomes may be influenced by gender differences in patients. In this study, I ask, “Are there gender differences in patient satisfaction with their heart failure team’s rounding model and care plans?” I screened data from questionnaires completed by patients hospitalized with a diagnosis of advanced heart failure at the time of study enrollment, at 10 days post-discharge, and at 30 days post-discharge as part of an ongoing parent study. I stratified data by an individual’s gender indicated in their medical records and cross-referenced that information with self-reported data from enrollment questionnaires. Participant recruitment is ongoing, of the more than 80 current participants, 66% identified as male (n = 56) and 34% identified as female (n = 29). Preliminary results, based on analysis of 23 quantitative questions on perceptions of rounds, indicate that there are gender differences in satisfaction, as nineteen of the questions had a difference in response by gender of .1 or more (including four that had a difference of .4 or more). For example, male participants rated accuracy of communication with their care team at a 4.3 out of 5.0 whereas female participants rated this at 3.8 out of 5.0. Additional research is needed to understand whether these differences are a result of differential treatment of male or female patients by care teams or other factors (e.g. differences in expectations or communication styles) as well as how to improve experiences and outcomes across genders.

Mentoring is an effective way to improve diversity and retention in STEM fields. The UW Psychology Undergraduate Mentoring Program (PUMP) matches psychology students from underrepresented groups with mentors, including undergraduates, graduate students, faculty, and alumni. Matches are made based on a combination of career interests and personal identities. In this study, we aim to understand predictors of mentees’ success in the program, defined by feelings of belonging, academic preparedness, and satisfaction with the mentoring relationship. These predictors include meeting characteristics and match characteristics. We hypothesized that in-person meetings, more frequent meetings, and greater similarities between mentors and mentees would be linked with greater success. 32 out of 168 mentees completed our survey on Qualtrics in Spring 2023. We measured meeting frequency (“How often did you meet with your mentor during [quarter]?”), format (“In what modality did you meet with your mentor? In-person, video/phone calls, texting, email”), match characteristics (e.g., whether the mentor and mentee shared similar demographics such as BIPOC, first-generation, or gender; how far apart they were in their class levels), belonging (e.g., “I know other people in the psychology major”), preparedness (e.g., “I feel prepared to pursue the psychology major at UW”), and satisfaction (e.g., “My mentor and I have had a successful mentoring relationship”). We will conduct correlations and multiple regression analyses to test the prediction that in-person meetings, more frequent meetings, and greater similarity between mentors and mentees will be linked with higher feelings of belonging, preparedness for the major, and satisfaction with the mentoring relationship. We hope to demonstrate that controllable variables such as these can improve program outcomes. Identifying the most effective program strategies, like in-person meetings or demographics-based matching, can aid mentees in our program and may also guide the development of new mentoring programs in other departments.

Prior research has shown that parent spatial language use predicts child spatial language use, and as a result, a child’s spatial ability. In our current study, we seek to identify factors that influence differences in both parent and child spatial language use. Using a picture book called “Flashlight”, which contains no words, parents were instructed to read aloud to their children (N=75 dyads, range: 2-4 years). Parents created their own story based on the pictures. After the storybook task, the parent and child were given blocks to play with for 5 minutes. Both these tasks seek to examine what types of language are naturally produced between parents and children, such as spatial words, questions, and number words (e.g., “at”, “What animal is that?”, and “one”). The videos of these sessions were manually transcribed. Parents also completed a series of questionnaires on their beliefs about the utility of play and their child’s language, motor, and communication skills. We hypothesize that the more questions a parent poses, the more spatial language a child will produce. This study is multifaceted in that it examines total language used overall (tokens), different types of language, free play, and spatial abilities. Studying these aspects of communication and underlying factors that impact the type of language parents use can lead to a better understanding of children’s spatial development and the factors influencing it. For example, parents who believe that play offers children unique opportunities to learn spatial concepts might use more spatial language with their children during play, which could scaffold their child’s spatial development. By identifying these factors, we can develop ways to increase spatial language use between parents and children, thus facilitating spatial development.

Lipotoxicity in cells occurs when lipids in biological tissue accrete to a toxic level. This toxic buildup is associated with obesity and type 2 diabetes, two of the leading causes of death around the world. Various studies have induced obesity in mice through a diet consisting of high levels of saturated fats. Some of these studies also investigated the effects Adefovir Dipivoxil, an antiviral and inhibitor of mitochondrial DNA replication, had on these obese mice. My research investigates fibroblasts that have been grown in a high-lipid environment and how Adefovir Dipivoxil affects these cells. We hypothesized that administering Adefovir to these cells would halt apoptosis and prevent further progression of lipotoxicity by stabilizing levels of triacylglycerol synthesis. To test this, I induced lipotoxicity in the cells using palmitic acid, a saturated fatty acid. Next, I treated the cells with Adefovir Dipivoxil. To measure the efficacy of the drug, I used a staining kit to measure the ratio of live to dead cells before and after administering the drug. Furthermore, I used a dye-based assay to measure the intracellular triglyceride levels before and after treatment. In addition to treating fibroblasts with palmitic acid, I treated a new set of fibroblasts with oleic acid, an unsaturated fatty acid, to determine how Adefovir acts on these cells. Data from this research will contribute to further understanding the mechanism of lipotoxicity on various cells, as well as the role that mediators of mitochondrial function like Adefovir Dipivoxil could play in treating lipotoxicity. On a broader scale, we hope that this research will provide insight into future treatments for obesity and type 2 diabetes.

Teachers play an integral part in a child's development as they are responsible for educating youth. Since COVID-19, schools are reporting rising rates of teacher burnout (52%) and students exhibiting problematic behaviors (e.g., disruptions [59%], disrespectful [52%], rowdiness [49%]). Disruptive classroom behaviors hinder the ability of teachers to adequately implement curriculum which results in a variety of disciplinary actions administered. My research analyzes the correlation between elementary school teachers' burnout rate and disciplinary actions taken. My data comes from a larger study that examined the implementation of a preventative social-emotional behavioral program in nine different schools. Teachers completed an online survey distributed in the middle of the academic year, including a measure on burnout, and the district provided systematically obtained disciplinary records (i.e., September to December) upon completion of the study. Preliminary analysis is ongoing to examine the relationship between teacher burnout and disciplinary actions recorded. This can be a first step towards improving teachers' professional well-being and creating a more prosocial classroom environment for student growth.

Sexual dimorphism describes the distinct characteristics between males and females of the same species. These different traits can be traced back to many external and internal factors. Here, we investigated how temperature and habitat influenced the evolution of sexual dimorphism in the mandible of mustelids. Mustelids are a great clade to study sexual dimorphism because of their mandibular diversity that is associated with their diverse diets, behavior, and ecological niches. We test two hypotheses: first, we examined if mustelids in high temperature environments exhibit higher degrees of dimorphism in their mandibles compared to those in lower temperature environments. Second, we test how the degree in dimorphism varies among mustelids inhabiting different habitats. To test our hypotheses, we quantified sexual dimorphism of mandibular size and shape using 3D geometric morphometrics. We then used phylogenetic ANOVAs to test how habitats influenced the degree of mandibular dimorphism and phylogenetic regressions to test how temperature influences the degree of mandibular dimorphism. We predict that mustelids in high temperature environments will exhibit a higher degree of sexual dimorphism than those in low temperature environments. Higher temperatures could correspond to a limited amount of resources which could lead to interspecies competition for food resources. As males and females use different strategies to survive, sexual dimorphism in mandibles size may occur. In our habitat analyses, we predict that mustelids in deserts will exhibit a higher degree of sexual dimorphism compared to those found in other habitats due to the same factors of resource availability and competition. Deserts tend to have scarce resources compared to forests and we believe that sexual dimorphism will reduce this competition. This research is impactful because as climate change is increasing temperatures all over the world, we should be aware of how that is directly affecting species.

Repetitive transcranial magnetic stimulation (rTMS) is a psychiatric treatment which has shown promise for experimental treatment of memory loss in Alzheimer’s Disease. rTMS uses a coil and electric current which is able to create a magnetic field that can depolarize neurons noninvasively and induce synchronized activity of large populations of neurons, ultimately inducing, lasting changes through synaptic plasticity. Alzheimer’s disease patients show disruptions in the Default Mode Network (DMN), a network of brain regions which is typically active at rest. The DMN has an important role in memory consolidation and is disrupted in Alzheimer's Disease. We hypothesize that strengthening the default mode network through rTMS applied to area left 8AV of the frontal cortex will create improvements in patient memory. To answer this question, we are performing a single-blind, single-arm, randomized cross-over trial of rTMS on early-stage Alzheimer's disease patients. Region 8AV is located by using MRI scans obtained before patients receive either the sham or experimental procedure. This region was chosen due to its connection to the default mode network and previous promising TMS research. Our primary outcome measure is the speed of forgetting, a new, reliable index of memory function obtained by fitting a computational model of episodic memory to behavioral data from an adaptive memory test. Due to the frequent use of rTMS in mood disorder treatment, we are using depression and anxiety scales to track possible mood improvements as a secondary outcome measure. MRI scans will also be analyzed to see if the experimental treatment caused any structural differences in patient brains. Should our hypothesis be correct, we expect to see improvements in memory or cessation of memory decline in patients. Successful treatment would provide a novel target for Alzheimer’s Disease treatment using rTMS, and additional evidence for the continued investigation of rTMS for Alzheimer’s Disease.

Infants perceive speech and acquire language amidst noisy and complex auditory environments. Thus, elucidation of the cognitive mechanisms governing speech perception under noisy conditions is crucial. Cortical encoding of the speech envelope has been one approach used to study speech-in-noise perception in adults. For infants, research shows that Infant Directed Speech (IDS) facilitates cortical encoding of the speech envelope in quiet conditions more than adult direct speech. However, it is unclear whether infants are able to track the IDS speech envelope amidst competing speech. To investigate this, we recorded the neural responses from 40 typically-hearing infants (20 seven-month-olds, 20 eleven-month-olds) to continuous IDS using electroencephalography (EEG) in three conditions: Quiet, Co-located Noise, and Separated Noise. The target stimuli consisted of naturally recorded IDS produced by two female English speakers. The noise stimuli consisted of a four-person babble constructed from audiobooks read by 2 male and 2 female English speakers. We presented stimuli at an overall level of 70 dB SPL via speakers placed at 0°, +90°, and -90° azimuth to infants sitting on a caregiver’s lap in a sound-attenuated booth. Our team analyzed EEG signals using the Multivariate Temporal Response Function (mTRF) toolbox in MATLAB. This backward modeling approach assesses whether the stimulus envelope can be reconstructed based on the recorded neural responses. Reconstruction accuracies greater than chance were observed in all three conditions for the majority of infants, suggesting that we were able to decode the speech envelope in both quiet and noise. Participants demonstrated the capacity to process speech, even amidst competing auditory stimuli, emphasizing speech perception competencies from an early developmental stage. These results support using the envelope model and mTRF method as a feasible method for investigating the development of speech-in-noise perception in infants and young children.

By 2050, it is predicted that over half of the global population will be over the age of 65. Therefore, it is of the utmost importance that we study the impacts of aging on human health and well-being. One major obstacle researchers face in seeking to understand human health relates to the extensive number of newly discovered biological systems that exist and interact in every individual at various levels and timescales. Furthermore, many well-known age-related neurodegenerative diseases are thought to begin years to decades before any clinically relevant symptoms are present. The current study attempts to address some of these challenges by examining the interaction of cognition with immune function, inflammation, gene expression, and the microbiome. This research will allow us to begin unpacking the complex interactions of these numerous biological factors and their impact on natural aging and age-related neurodegenerative diseases. To accomplish these goals, our project has created and implemented a novel high-throughput cognitive testing system to assess a range of cognitive abilities including, but not limited to, attention, memory, and object recognition, on two species of well-known non-human primates (NHPs). At numerous time points, we concurrently collected and analyzed blood, fecal, and cerebrospinal fluid to characterize each animal's health profile. With our collection of data sets, we anticipate that older NHPs will display higher levels of neuroinflammation and decreased immune function. We hope to find correlations between these factors and other variables with genes that are known to be related to a host of neurodegenerative diseases including Alzheimer's Disease (AD), Alzheimer’s Disease-Related Dementia (ADRD), and Parkinson’s Disease, among others. Results from this ongoing project will unravel mechanisms associated with age-related neurodegenerative diseases, allowing for earlier detection; this early detection is regarded as the most effective approach for preventing and treating such diseases.

Mind-wandering, characterized by the inward direction of attention towards thoughts, represents a widespread cognitive phenomenon that can disrupt task-related attention. Evidence indicates that the frequency of mind-wandering increases during sustained attention tasks, and previous research has proposed several hypotheses, such as resource-depletion, control-failure, and resource-control hypothesis, to explain the increases as well as the declines in task performance from their perspective. This study first aims to investigate the impact of incorporating a strategy of break on the frequency of mind-wandering during a Sustained Attention to Response Task (SART). It seeks to determine whether a break strategy can mitigate the frequency of mind-wandering and to identify which of the aforementioned hypotheses best fit the experiment outcome. Specifically, it examines whether a rest break or a task-switching intervention can reduce the frequency of mind-wandering, comparing these effects to a no-break condition. Forty students from the University of Washington will participate in a four-part experiment that includes two 480-trial SART tasks, an intervening break condition (rest break, task-switch, or no break), and a concluding questionnaire. Mind-wandering will be measured through thought-probe methodology, and task performance will be assessed using error rates and response times. Additionally, subjective workload and fatigue level will be assessed using NASA Task Load Index (NASA-TLX) questionnaire. Based on the three existing hypotheses and behavioral data, the second aim of the study is to construct three cognitive architecture ACT-R models, and by comparing different models to reflect potential mechanisms of the role of breaks in mind-wandering.

Social interactions in humans have shown to improve pain outcomes and diminish the development of mechanical hypersensitivity (allodynia) following injury. This effect is known as social buffering of pain; however, the underlying mechanisms are not well understood. Prior preclinical studies focused on forced social interactions between unfamiliar mice, lacking translational value to patients. To fill this gap, our research explores how volitional social behavior shifts pain sensitivity and affect following a neuropathic injury. Volitional interaction is key to socialization as individuals usually socialize because they want to, not due to force, which makes studying how mice voluntarily interact with each other important. To determine how volitional social interaction impacts both sensory and affective (emotional) components of pain, we use male and female mice who have received a spared nerve injury (SNI). Trained in social self-administration, mice learn to lever-press to engage with a familiar conspecific. Mice are then tested in von Frey where thin plastic filaments of increasing weights are applied to the mouse hind paw before and after SNI. These filaments do not cause pain, rather elicit a pain response of withdrawing the paw. To determine sensory sensitivity, the weight when the animal's paw is withdrawn is recorded as percent change from baseline. To determine changes in affective pain, the amount of time the animals hold their paw up, following withdrawal, is recorded as percent change from baseline. We found that male and female mice show significant attenuation in their mechanical hypersensitivity following volitional social interaction compared to mice deprived of volitional social interaction. Males show even less mechanical sensitivity, indicating that males may be more impacted by social analgesia than females. Understanding the divergent responses between male and female mice and the role of volitional social interaction in pain modulation, offers potential avenues for developing novel therapeutic strategies.

Autism spectrum disorder (ASD) is defined as a complex developmental condition involving persistent challenges with social communication, restricted interests, and repetitive behavior. The development of autism spectrum disorder (ASD) has been associated with altered brain development in infants with high familial likelihood for developing the disorder. Some of the same subcortical regions associated with altered brain development in ASD are also associated with sleep problems, including the hippocampus. Healthy sleep is an integral contributor to brain development during childhood and there is increasing evidence that chronic sleep loss can lead to neuronal loss and impaired functioning. Additionally, the multi-site, NIH-funded Infant Brain Imaging Study (IBIS) has previously reported sleep problems are associated with hippocampal alterations in infants who developed ASD. However, the relationship between sleep problems and altered brain development in autistic school-age children is not well understood, even though clinically significant sleep problems affect 75-80% of this population. Based on prior findings from the IBIS network, this project will examine the relationship between hippocampal volume and sleep problems in 137 school-age children with high familial likelihood of ASD (HL-ASD), no diagnosis of ASD (HL- noASD) and low familial likelihood of developing ASD (LL). Our prior findings suggest there will be differences across the three school aged groups in hippocampal volume, sleep duration, and sleep quality. We also expect that hippocampal volume in the HL-ASD children is differentially affected by sleep quality and sleep duration compared to the HL-noASD and LL children. Understanding the connections between sleep patterns and autism will help steer future research endeavors examining a largely understudied but significant issue. Additionally, this project will provide new insights into the negative consequences associated with chronic sleep loss in autistic children, affecting both their daily functioning and their quality of life.

Prosocial behavior is important to many species and its disruption is a hallmark symptom of many diseases and disorders such as autism. Previous research has shown that the mesostriatal network, which consists in part of neurons located in the midbrain that make the neurotransmitter dopamine and release it downstream in the nucleus accumbens, plays an important role in prosocial behavior. Dopamine neurons express the potassium ion channel Kv7.3 and mutant variants of Kv7.3 have been identified in individuals with autism spectrum disorder (ASD). Here we investigate how the Kv7.3-R2C variant found in ASD patients impacts social behavior and dopamine release in mice. We use viral strategies to express human Kv7.3-R2C in mouse dopamine neurons and a genetically encoded dopamine sensor (dLight1.3) in the nucleus accumbens during a social operant task. We found that while Kv7.3-R2C expression decreased social reward in an operant task rewarded with social behavior, dopamine release was similar between groups. Findings from this study help improve our understanding of how deficits in the mesostriatal pathway may lead to decreased social interaction in patients with ASD.

Challenges with social-emotional reciprocity, such as initiation of and response to social interactions, are a core diagnostic criteria of autism spectrum disorder (ASD), and many children with ASD experience challenges with expressive language. Prior research demonstrates parents are accurate reporters of language and fine motor skills development, but may under report social emotional reciprocity. The goal of my study is to discern how well parent concerns around child social-emotional reciprocity and language correspond to observed virtual interactions with their child. In a larger study investigating interventions for children with social communication concerns, parent participants of toddlers aged 25-41 months (n=41) completed the Toddler Autism Symptom Interview (TASI), a structured interview about core autism symptoms, over Zoom. Parent-child interactions were recorded in the same session while they completed the TELE-ASD-PEDS (TAP), a telehealth ASD assessment for toddlers. As part of the larger study, I am assisting with coding child expressive language, including use of words and multi-word combinations. For my independent research, I am coding child behavior on two tasks from the TAP, ‘calling the child’s name’ and ‘approaching others to play’. ‘Calling the child’s name’ is coded as the number of times the child stopped what they were doing to look at their caregiver when their name was called, while ‘approaching others to play’ is the number of times the child approached their caregiver during a 2-minute period where their caregiver was instructed to sit back and ignore their child. I will compare coded behaviors with corresponding items on the TASI. I hypothesize that parent reports will be more consistent with coded observations for language concerns than for social-emotional reciprocity behaviors. Understanding whether social-emotional reciprocity is being accurately reported by parents can help clinicians provide accurate diagnoses for ASD, especially given the critical role of parents in the diagnostic process.

Elementary school educators are primary influences on children’s development by helping shape their behavior with peers and in the classroom. Employees in education are deferred to by their newer coworkers regarding student interactions and set precedents for students’ school environment. New and seasoned educators’ disciplinary practices greatly vary when addressing students exhibiting problematic behaviors which may differently affect student-instructor relationships. I use an existing dataset from a larger study testing the impact of a novel implementation strategy on the implementation of a universal social, emotional, and behavioral program in nine elementary schools from one district. Educator participants in this study completed a survey battery when starting and ending the school year and the district provided quarterly discipline records via a universal prevention program. The findings identify trends in student disciplinary actions between new (<5 yrs) and experienced (>5 yrs) instructors. Understanding the relationship between teacher tenure and the treatment of student misbehavior is crucial to demystifying the manifestation of poor student enrichment and hostile student-instructor relationships. These findings could suggest how differential disciplinary practices by educators based on their years of experience influence student learning.

Primary care providers are responsible for utilizing well-child-check-ups to screen toddlers for autism spectrum disorder and immediately refer children with increased likelihood to diagnostic and intervention services. Participating in intervention services at young ages is extremely impactful as it often allows children to develop their social, cognitive, and language skills. However, it is estimated that only 40% of children who screen at an increased likelihood for autism are being referred to recommended services by their providers. It is especially important to look at autism referral rates as autism is half as likely to receive a referral from a provider than other developmental concerns. This mixed-methods study used a video vignette and focus groups to investigate factors influencing primary care providers’ decision- making regarding autism referral in a well-child-check-up setting. We examine the role of provider attitudes, autism knowledge, and distribution of attention (information providers attend to during a visit). We anticipate that providers will exhibit low knowledge of autism and intervention, and believe information about autism that has empirically been proven to be false. Additionally, we expect that providers pay less attention to clinically significant behavioral information than physical information during a well-child-check-up. Overall, we aim to understand what influences provider’s referral decisions to provide insight on a development of a future primary care provider intervention that supports the increase of autism referral rates. Ultimately, improving the developmental prognosis of children with autism.

The potential cognitive benefits of mindfulness meditation, such as its effects on memory processes, are gaining increasing attention. The growing interest in mindfulness meditation as a technique to improve cognitive functions, particularly long-term memory, motivates this investigation. The purpose of this study is to determine how mindfulness meditation affects the individual’s rate of forgetting in long-term memory as practice days increase. Using a computational model of episodic memory fitted to data obtained from an adaptive memory test, the study is able to monitor and predict the rate of forgetting for each individual and acquire a deeper understanding of how mindfulness meditation influences individual differences in memory retention and retrieval. The study will recruit thirty healthy participants through the Psychology Subject Pool of the University of Washington. The participants will be randomly assigned to either a group that practices mindfulness meditation or a control group that engages in podcast listening. For six days, participants will complete online memory tasks before and after each mindfulness meditation session or podcast listening session, while their performance data will be analyzed to model the rate of forgetting. To assess the principal effects of mindfulness meditation on the rate of forgetting, statistical analyses, such as linear mixed models, will be employed. We hypothesized that participants who participate in mindfulness meditation will have a lower rate of forgetting than those in the control group who engage in podcast listening after six days. Moreover, the study also hypothesizes that participants engaging in mindfulness meditation will demonstrate a decreasing rate of forgetting as the number of practice days increases. The finding of this study may inform interventions using mindfulness to enhance memory retention, benefiting those with age-related cognitive decline or stress-related memory challenges. It contributes to understanding the potential of mindfulness in cognitive function and memory-related disorders.

Universal social, emotional, and behavioral interventions (SEBIs) have been shown to have positive impacts on prosocial behavior in students. When teachers implement SEBIs, their openness to adopt an intervention is an important factor that affects intended student outcomes. Research has shown that a teacher’s openness to SEBIs improves the effectiveness in positively influencing student behavior, which in turn improves student outcomes. This study will investigate the relation between teacher openness towards SEBIs and positive and negative student behaviors. We will conduct a cross-sectional analysis from a survey taken by teachers two weeks after receiving training on an evidence-based intervention. We anticipate that there will be a positive correlation between teacher openness and positive student behaviors. It is vital to understand the connection between teacher openness towards the adoption and implementation of SEBIs and the behavioral outcomes of students as it helps optimize information about how to best support students.

Seriously ill hospitalized patients and their families experience elevated stress, anxiety, and depression, resulting from factors like the complexity of serious illness, fragmented medical care, and transitions across settings. They struggle to navigate treatment options, make difficult decisions, and express their values and goals to their clinicians. In addition to communication challenges between patients and clinicians, poor communication among healthcare team members exacerbates the stress associated with serious illness. The aim of this study was to continue work from previous Facilitating Communication Studies to gain knowledge from bedside nurses' experiences with collaborative communication (CC) between patients and families and their healthcare team, and to elicit ideas from nurses about what might improve CC within the hospital system. We defined CC as patients and families being active participants with their healthcare team working towards shared goals of care. We recruited and interviewed 15 bedside nurses from ICU and acute care units at Harborview Medical Center. Following each interview, we input each participant's audio-recorded content into a matrix table, created summaries of each transcript, and synthesized content across transcripts to distill major themes. Nurses reported that breakdowns in CC most often occur when multiple clinicians are involved, during transitions of care, and during the discharge process, resulting in confusion and distress for the patient, family, and bedside nurse. Suggested solutions to overcome these barriers include (1) promoting in-person interactions by rounding as an interprofessional team, (2) inviting bedside nurses to goals of care meetings, (3) implementing a CC training program for clinicians to standardize the CC approach among team members, and (4) empowering patients and families to initiate CC by educating them about their role in their healthcare. These suggestions should be implemented in a future Facilitating Communication Study to reduce distress for seriously ill patients, their families, and their healthcare team.

Spatial skills are crucial for understanding and navigating the physical world around us. Previous research indicates spatial development begins in infancy, with sex differences present early on. These skills are predictors of later STEM achievement, highlighting the importance of nurturing them from a young age. Our study explores the impact of spatial language and play style on infants’ spatial development. We replicated a change detection mental rotation task for infants using an eye-tracker (N = 115, 47 girls, M age = 11.21 months). As infants preferentially look at novel stimuli, we recorded looking time as a measure of recognition of a change in stimulus. Additionally, we observed parent-infant dyads during play, and parents completed a survey on their infant's play, language, and motor skills. We hypothesized that parents would use more spatial language during spatial play than non-spatial play. We were also interested in whether play and language use varied by child sex. Infants showed no preference for the novel stimulus in the mental rotation task, suggesting it might not effectively measure mental rotation in infancy. Parent-infant dyads varied in engagement with the spatial toy, and no significant sex differences emerged from these measures. Due to the null findings in our change detection task, we will be designing and testing a new task for measuring mental rotation ability in infancy. Furthermore, we will also conduct analyses on the relationship between individual differences in spatial language and play to explore how these factors impact the development of spatial abilities. These findings provide insights to better support spatial development in early life.

The intersection of data visualization and qualitative research has seen a lack of importance within the scientific field. Its potential to advance the field is diminished due to the challenges researchers face when working with qualitative data and the lack of appropriate visualization methods. WordStream is a qualitative data visualization type that aids researchers in visualizing nuanced perspectives of qualitative data. Within the user study, we purposefully recruited participants who have a background in STEM education research along with qualitative methods. We present a user study of two WordStream-based platforms, Journal Data Dashboard and WordStream Maker, that surveyed participants in STEM education research who use qualitative methods to garner insights. A mixed-method study allows us to examine visualizations and a questionnaire to explore our topic. Our initial study consists of 4 respondents, with a plan to increase to 10 respondents. We apply a Likert scale to our questionnaire to investigate and measure the ease of use and usefulness. Additionally, our method analyzes open-ended questions regarding trust, envision use, and desired features. Through quantitative and qualitative analysis, we report user preferences between the two qualitative visual analytic platforms. Two themes emerged: (1) Users prioritize functions that increased their visual control to explore the data in context; (2) Users’ perspectives reflect a strong context of use in evaluating the WordStream functions related to their areas of expertise. Preliminary findings from four participants show that users prefer the Journal Data Dashboard to the WordStream Maker for ease of use and usefulness. The study is ongoing, and we will present additional data and the implications of the findings for improving Wordstream and designing other qualitative visual analytics.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by difficulties in social communication and interaction, and restricted or repetitive patterns of behavior or interests. ASD is associated with features beyond its core characteristics, including alexithymia and anxiety. Alexithymia is characterized by difficulty recognizing and describing one’s own emotions, it influences physical and mental health, and it is associated with symptoms of anxiety. Despite current research demonstrating the correlation between alexithymia and anxiety in both ASD and the general population, there remains a significant research gap in how alexithymia and autism traits individually and collectively influence anxiety levels among the participants. This study has two aims: 1) To explore the relationship between alexithymia and anxiety in participants with ASD and TD. 2) To analyze the role of alexithymia as a mediator of the relationship between autism traits and anxiety in adolescents and young adults. This sample includes 149 participants (93 ASD) ages 15-34, from the NIH funded study on sex differences in autism. Measures included alexithymia via the 20-Item Toronto Alexithymia Scale (TAS-20), anxiety via the Screen for Adult Anxiety Related Disorders (SCAARED), and autism traits via the Social Responsiveness Scale (SRS-2). We will first conduct regression analyses to examine the relationships between alexithymia, anxiety, and autism traits. Then, we will employ Preacher and Hayes’ INDIRECT Method to investigate the mediating role of alexithymia in the relationship between autism traits and anxiety. We expect to see a significant relationship between alexithymia and anxiety in both groups and the relationship between alexithymia and anxiety in the ASD group to be significantly different than TD group. Understanding the relationship between anxiety and alexithymia could aid in the development or improvement of interventions for anxiety in people with ASD.

In this pilot project, we conducted think-aloud interviews with undergraduate students who had recently completed CHEM 142 as they worked through a set of multiple-choice, general-chemistry questions in order to investigate the levels of cognition they exhibited during problem solving. In collaboration with members of my research group, I designed recruitment materials and selected eight undergraduate interviewees from a pool of around 50 volunteers, with attention to diverse identities— including race, gender, sexuality, disability, prior courses in science/math, and parent’s educational background—as such identities and experiences may influence what problem-solving skills one has acquired. I co-developed the interview format, and conducted two of eight interviews. Participants were asked to narrate their approach while solving four multiple-choice CHEM 142 questions, then to critique the questions in terms of relative difficulty. The questions we used were previously characterized according to Marzano and Kendall’s New Taxonomy of Educational Objectives by a group of chemistry educators from our research group. I developed and refined a modified version of Marzano’s Taxonomy inspired by Teodorescu’s work in introductory physics (Teodorescu et. al., 2013), and am using it to code the interviews according to cognitive level exhibited by the interviewees. My preliminary results suggest that students approach a particular question in a variety of ways, engaging different levels of cognition. Students who display mastery of a concept tend to utilize lower cognitive levels, apparently due to familiarity with the concepts. Students who seem less familiar with or state they are struggling with a topic tend to employ more cognitively demanding strategies, whether or not they arrive at the correct answer. I will also discuss a comparison of the cognitive level exhibited by students to the level predicted by previous group members for each question, and any observations unique to different student identities.

Sensory processing is a process in which the nervous system receives, processes, and integrates incoming sensory input from the environment to allow individuals to perceive and respond to their surroundings. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social and behavioral skills. Many individuals with ASD experience hypersensitivity to sensory stimuli, thus individuals with ASD may experience more difficulty when navigating the world around us. These sensory challenges may result in increased anxiety symptoms. The purpose of this study was to explore the relationship between sensory processing and anxiety in autistic and typically developing (TD) adults. 256 participants (ASD = 149) ages 18-35 from a NIH funded study on sex differences in autism were included. Participants completed two self-report questionnaires: “Sensory Processing 3-Dimensions Scale” (SP3D) measuring sensory processing difficulties in auditory, visual, and tactile domains, and the “Screen for Adult Anxiety Related Disorders'' (SCAARED), measuring the intensity or frequency of anxiety symptoms and assessing four factors of anxiety (panic disorder, generalized anxiety disorder, separation anxiety disorder, and social phobis disorder). Correlations will be used to compare SP3D scores and SCAARED scores. Given the hypersensitivity to sensory stimuli in ASD, we hypothesize the effects of anxiety symptoms will be increased in the ASD group who experience more domains of hypersensitivity. The results of this study will contribute to a greater understanding of the effect sensory sensitivity has on anxiety in adults with ASD.

Children diagnosed with Autism Spectrum Disorder (ASD), often experience co-occurring language impairments, including grammatical and lexical difficulties. Word segmentation, or the ability to identify word boundaries in continuous speech, is done through statistical learning and identification of speech cues. Recent studies in typically developing infants have shown a linear relationship between the ability to recognize words from continuous speech and the size of an individual's lexicon. The neural activity of the cerebral cortex, specifically the delta frequency band (1-4 Hz), contains the time scale of words and phrases. The delta band was found to track speech rhythm, along with semantic dissimilarity between successive words. Extracting acoustic features from sound signals and their linguistic representations (syllables, words, and phrases) is essential for speech comprehension. This study aims to look at the relationship between delta power recorded via scalp electroencephalogram (EEG) and communication skills in children with and without ASD. 193 participants (ASD = 96) from the NIH study on sex differences in autism were included in the sample. EEG recordings were collected while participants listened to phonemes that were statistically presented to result in 4 learned nonsense words. Parents completed a semi-structured interview on their child’s communication skills. EEG delta power was calculated over frontal, central and posterior regions of interest (ROIs). We expect children with ASD (compared to typically developing children) to have decreased delta power during nonsense word perception and lower delta power will be related to lower communication ability. This study will provide insight into the relation between neural perception of language and verbal communication in children with ASD.

Latino people constitute the largest minority in the U.S., and diabetes is an urgent health issue that impacts the Latino community at twice the rate as white Americans. Existing literature on Latino populations suggests that culturally competent care is critical for important health outcomes like satisfaction, and interventions to improve cultural competency in diabetes care for Latino patients significantly impact clinical outcomes. However, there is limited research on how Latino patients define culturally competent diabetes care. Previous research in South Asian communities demonstrates that the pathologization of culturally relevant foods may cause diabetic patients to face poor metabolic control and increased risk of complications, leading to higher healthcare costs and lower quality of life. Despite research indicating that food pathologization is a barrier to high-quality diabetes care for some minoritized groups, previous research on diabetes care in the Latino community does not focus on food pathologization in diabetes care.Through an ethnographic study in clinics in the Greater Seattle area, we seek to understand the experiences of Latino people managing type 2 diabetes related to discussing culturally relevant foods with providers. We will recruit Latino patients to participate in structured interviews exploring how providers discuss culturally relevant dietary choices in diabetes care appointments. We will conduct content analysis to uncover themes related to food pathologization and the downstream impacts of how providers discuss food choices with Latino patients. By studying the relationship between possible food pathologization and diabetes care, we hope to contribute to a holistic understanding of the benefits of culturally competent care. Ideally, our findings may help to reduce food-related stigma and prejudice experienced by Latino diabetes patients.

Experiencing a stressful situation in the presence of another person can lead to two distinct outcomes: a decrease in fear response (social buffering) or an increase (social contagion). Understanding these phenomena and the factors influencing them is essential for advancing the treatments for anxiety and fear-related disorders. In this study, I am investigating how gender and social context can impact fear response and risky decision-making. To do this, I am using a naturalistic foraging task that allows rats to exhibit a wider range of behaviors and provides data that more accurately reflects real-world scenarios beyond the laboratory. The study involves alternating between paired and single trials where rats (n = 10) venture from a safe nest to retrieve food in an open arena where a realistic aerial predator can emerge. I am measuring fear responses to the predator through various quantitative variables, including the latency to leave the nest, the latency to retrieve the pellet, and the number of attempts made. I have concluded data collection on the male pairs, revealing an unexpected trend: male rats displayed greater fear responses in paired trials, indicating social contagion rather than the anticipated social buffering. This preliminary finding suggests that the presence of a single companion may heighten fear responses. I hypothesize that female rats will show a similar (intensified) trend because they tend to be more cautious foragers.

Individuals differ in how easily they perceive and internally represent visual and verbal information. However, these differences in information processing style are not all or nothing; individuals vary not only in the direction of attentional bias, but also its strength. Prior research found that when forced to choose between competing visual and verbal stimuli, people exhibit different degrees of bias when selecting what information to attend to. The present study examines whether individuals with greater visual or verbal attentional biases, relative to neutral attenders, show different levels of sensitivity to conflict between visual and verbal information during a categorization task. Data will be analyzed from 185 participants who completed a card sorting task in which they were asked to sort stimuli into one of three card suits. Each trial contained visual (shape) and verbal (word) representations of the card suit. On 75% of trials, the word and shape matched (congruent) and the other 25% of trials contained inconsistent information (incongruent). Our analysis will compare response times on incongruent and congruent trials (incongruency effect) in high- and low-biased individuals, to measure conflict experienced. We hypothesize that individuals showing a greater attentional bias towards either task modality will ignore information that is misaligned with their preferred information processing style, resulting in a smaller incongruency effect. These results would suggest that biased attenders have quicker access to the information that aligns with their processing style, while neutral attenders notice both information types and experience conflict when they are incongruent. Alternatively, if attentional bias is unrelated to incongruency effect magnitude, this suggests that people process information similarly, and experience biases only at the decision phase. This study has important implications for understanding how individual differences in information processing style affect how much information individuals process in situations with attentional competition.

Periodontal disease is a prevalent oral disease most frequently found in older adults, and left untreated can lead to inflammation, bone loss, and patients may lose their teeth. Treatment of periodontitis includes repeated maintenance by a dentist and surgical procedures. These treatments can be invasive and time-consuming and do not target the underlying molecular changes that occur during the aging process. Previously, the mTOR pathway was shown to decrease inflammation and bone loss during periodontal disease in aged mice. Here, we investigate if targeting a marker upstream of mTOR, called colony-stimulating factor 1 receptor (CSF-1R), can recapitulate the effects of targeting mTOR. CSF1-R plays a role in inflammatory diseases by regulating myeloid cell lineages such as macrophages and osteoclasts. We hypothesize that inhibiting CSF-1R will decrease the expression of inflammation markers associated with periodontal disease in aged mice. Real-time quantitative PCR was used to identify relative expression levels of various inflammatory markers involved during aging and periodontal disease, including IL1-a and IL1a. Quantitation and analysis were completed by first standardizing target genes relative to ß-actin and GAPDH expression. Data was analyzed where appropriate using one-way analysis of variance (ANOVA) with post-hoc Tukey test for multiple comparisons, where p-values <0.05 were considered statistically significant. Statistical analysis was completed on GraphPad Prism 10.0. Our analysis demonstrates that CSF-1R inhibition decreases multiple cytokines involved during periodontal disease and major isoforms of the PI3K pathway. These findings indicate the importance of the CSF1R signaling along the mTOR pathway and possible implications for future research.

Hypoxia-ischemia (HI), or brain injury caused by a lack of blood flow and oxygen to the brain, is a leading cause of infant mortality and morbidity. Contrasting between ages, the effects of HI tend to be more severe in younger neonates. Curcumin, a dietary compound derived from turmeric, exhibits anti-inflammatory, antioxidant, and antiapoptotic properties, but is not bioavailable in molecular form, thus may serve as a neuroprotective treatment when loaded into synthetic nanoparticles to allow for effective absorption and crossing of the blood-brain barrier, forming the treatment NanoCurc. Gestational ages of 37 weeks through 42 weeks are all considered term neonates, yet their brain continues to develop and differ significantly in response to treatments against HI. Using the rat Vannucci model of unilateral hypoxic-ischemic brain injury, we studied the in vivo effects of NanoCurc in neuroprotection, in P7, P10, and P13 rats, equivalent to 34, 38, and 42 weeks’ gestation, respectively. Tissue is collected 72 hours after unilateral carotid artery ligation surgery, followed by tissue staining and analyzed by tracing the healthy tissue versus damaged tissue, to calculate the average percent area loss in treated and untreated rats. I hypothesize that in all ages, neonatal rats treated with NanoCurc will have lower injury in comparison to those treated with saline (vehicle), while the treatment will be more effective in younger rats in comparison to older ages. In the future, NanoCurc treatment may be used as a neuroprotective agent in reducing the effect of HI in preterm and term infants. If NanoCurc provides a stronger neuroprotective effect in the younger population, it may serve to target infants most severely affected by HI, potentially creating personalized treatment for gestational ages.

Autism Spectrum Disorder (ASD) is a neurological and developmental disorder that affects around 1 in 6 children and 1 in 65 adults in the United States. Autistic individuals experience difficulties in social communication, interaction amongst peers, and language skills; any of the symptoms of ASD cause an influx of other problems that continue into adulthood; these differences may impact self-esteem and feelings of acceptance. Previous research has shown that a history of mental health concerns is related to worse Quality of Life (QoL) in individuals with autism as they transition into adulthood. This project aims to examine mental health comorbidities and self-reported QoL in adults with autism. 44 autistic adults from the NIH funded study on sex differences in autism were included. Participants completed a self history of current mental health diagnosis (anxiety, depression, OCD, ADHD etc.) and self reported QoL. Participants were grouped into 3 groups based on diagnosis: 1 (no diagnosis), 2 (1 diagnosis), and 3 (2+ diagnosis). QoL scores for each group will be calculated from the World Health Organization Quality-of-Life Scale (WHOQOL-BREF). I predict that individuals with more comorbid mental health diagnoses will have lower QoL scores. These data will inform us of how additional mental health struggles may impact quality of life in individuals with autism.

What is personal space? It describes the “invisible bubble” immediately around an individual, where intrusion by others may feel uncomfortable or even threatening. Despite personal space being important for determining the size and dynamics of large groups and how animals behave, it is unknown how animals generate and maintain their sense of personal space. I explore this question using Drosophila flies, a powerful model system for studying behavior. Individual flies communicate via a large set of behaviors (e.g. kicking, flicking the wings, flying, and running) that can shape group interactions. Between pairs of flies, there is a rich repertoire of interactions that cause them to either move away (e.g. appendage touching) or move closer (e.g.courtship behaviors). To capture these behaviors, I use high resolution cameras running at 150 fps to collect videos of flies interacting in a circular arena and deep-learning software for annotating body parts (SLEAP). I use this data to track the poses of multiple flies throughout time and quantify appendage touching behaviors in addition to an estimate of each fly’s personal space. Using optogenetics, I model a situation in which a wild-type fly responds and adapts to being surrounded by other flies that crowd tightly. One expected outcome is that the wild-type fly will increase appendage touching in response to the space around itself shrinking. My goal is to determine exactly how the dynamics of such inter-fly interactions form a sense of personal space for each fly. My work will uncover the patterns of interactions that develop personal space and how these patterns scale out to larger social networks.

This project focuses on the redesign of a faculty research website with the objective of enhancing the site’s user experience. The project documents the history of Egyptology in the late 19th and early 20th century, through the lens of unpublished personal archives. The target audience includes scholars working in the discipline of Egyptology, students within the Middle Eastern Languages and Culture department at the University of Washington (UW), and the general public, for whom survey research will be conducted. The research methodology takes a multi-faceted approach, incorporating contextual inquiry-based interviews to observe user interactions with prototype designs. Additionally, in-depth interviews will be conducted with Middle Eastern Languages and Culture professors, and independent scholars, to gather insights on the presentation of the website. The survey research gathers feedback from UW students, gauging their preferences, expectations, and challenges when interacting with Egyptology-related online resources. Through contextual inquiry-based interviews, the project aims to identify user behaviors, allowing for the development of user-centric design solutions. The involvement of Middle Eastern Studies professors in interviews adds an academic perspective, enriching the redesign process with expert insights. The redesign process will address identified user needs and preferences, streamlining navigation, and optimizing content presentation. The redesign process will prioritize fulfilling the requirements and needs that we find through our user experience research. Iterative prototyping allows for user feedback to be continuously integrated, ensuring the final design aligns with the expectations and requirements of the target audience. By combining survey research, contextual inquiry-based interviews, and expert insights from Middle Eastern Studies professors, this project aspires to create a more engaging and user-friendly Egyptology website. The outcomes of this redesign endeavor aim to contribute significantly to the improvement of academic online resources, fostering a seamless and enriching learning experience for students in the Near and Middle Eastern Studies department at the University of Washington.

Leigh syndrome (LS) is the most common form of mitochondrial disease in children. It affects 1 in every 40,000 births and its clinical manifestations include ataxia, seizures, failure to thrive and premature death. Genetic mutations in more than 75 different genes have been associated with LS. Among them is NDUFS4, the gene that codes for a subunit of the protein complex I of the mitochondria. Mice carrying a whole-body knockout (KO) of this gene greatly model this illness; they recapitulate multiple phenotypes of LS in patients. Prior studies in the lab have shown that the KO of Ndufs4 in GABAergic neurons, not in excitatory neurons, across all brain regions, reproduce the epilepsy phenotype seen in the global KO mice. Surprisingly, new KO mice with Ndufs4 inactivation restricted to GABAergic neurons of the brainstem and cerebellum interneurons, mediated by GlycineT2Cre, also have epilepsy. In this study, we sought to uncover the brain regions that house neurons involved in seizure activity in these mice. Brain regions experiencing neuronal hyperactivity during seizures in this new model of LS were examined. A thermal seizure was induced in the Ndufs4 GlycineT2Cre KO mice. For control condition, mice were exposed to a sham experiment. Forty-five minutes after the seizures or sham procedure, the mice were anaesthetized, and their brains were fixed and harvested. Brain slices were prepared and stained with a c-Fos antibody and finally imaged on the confocal microscope. Interestingly, high c-Fos immunoactivity was observed in the cerebellum alone and not in forebrain brain regions generally known to be involved in seizure generation. These findings indicate the participation of the cerebellum in seizure generation in Leigh syndrome epilepsy. In future studies we plan to increase the sample size and confirm the results with statistical methods.

Including undergraduate peer facilitators (UPFs) in lectures is often done to support students in large and often challenging introductory science courses. Our team increased UPF involvement by creating BIOL113, an undergraduate-led companion course to BIOL180, the largest biology course at the University of Washington. This study is a part of a larger project that assessed the overall experience of both UPFs and students, and this particular work focuses on the latter. We examined how BIOL113 enhanced students' learning and academic success in Introductory Biology. By incorporting quantitative and qualitative data, we compared the performance of students who received UPF support in this companion class with those who did not. Quantitative data included grades, exam scores, and course completion rates, while qualitative data encompassed students' perceptions of peer facilitation though blast surveys. We found that undergraduate-led programs play a unique role in improving students' learning and including UPFs promoted peer-to-peer interaction and student engagement. Additionally, UPFs serve as relatable role models, providing mentorship and practical guidance. Moreover, programs like BIOL113 have a rare opportunity to disproportionately support students from minoritized groups. Understanding the impact of BIOL113 on students' success can inform instructional strategies, with potential expansion of such programs across the University.

Social connection is fundamental to human well-being, encompassing mental and physical health, and overall quality of life. The importance of forging deep, meaningful relationships is a key focus within relationship sciences. Evidence from 140 studies highlights the significant impact of loneliness on health, equating its risk to that of severe health behaviors and conditions, such as heavy smoking. This underscores the essential role of close relationships in maintaining health. The process of building these relationships, according to relationship sciences, involves mutual disclosure and perceived responsiveness. While extensively studied in individual interactions and laboratory settings, group dynamics remain less explored. Functional Analytic Psychotherapy (FAP), a treatment developed at the University of Washington that is practiced by clinicians worldwide, indicates that relationships strengthen when vulnerable disclosures are met with validating and compassionate responses. The principles of FAP, distilled into the concepts of Awareness, Courage, and Love (ACL) are now being disseminated to the general public through the ACL relational model. A randomized-controlled pilot study with 10 participants evaluated the impact of a three-week ACL group intervention on depression in a clinically depressed sample, using the Montgomery–Åsberg Depression Rating Scale for assessment. The intervention, focusing on exercises in self-disclosure, reflection, and compassionate response, demonstrated promising results. Participants showed significant reductions in depression symptoms and increased self-compassion compared to a control group engaging in self-guided, personally meaningful activities. This study indicates the potential of ACL group interventions in enhancing self-compassion and alleviating depressive symptoms, highlighting the importance of supportive group dynamics in mental health improvement. The findings advocate for the integration of relationship-focused practices in mental health interventions, emphasizing the value of vulnerability and mutual support in fostering psychological well-being.

Heschl’s gyrus (HG) is a region of the brain containing the primary auditory cortex. The extent of folding within the HG shows high morphological variability across individuals. Interestingly, increased HG folding is more likely to be found in expert than amateur musicians, suggesting a possible role of auditory experience in shaping HG gyrification. In my research, I examined HG folding in blind individuals—another population with extensive auditory experience. I hypothesized that, if experience alters HG structure, then individuals with early-onset blindness might have increased HG gyrification compared to those with late-onset blindness or those who are sighted. I analyzed T1-weighted images collected from previous MRI studies at the University of Washington, University of Pennsylvania, and Oxford University. The combined dataset included 6 anophthalmia (individuals born without eyes), 48 early blind, 18 late blind, and 28 sighted control participants. I created hand-drawn HG regions of interest for each participant in both hemispheres and measured HG gyrification in two ways: 1) by visually categorizing the extent of HG folding (single, partial, or complete duplication), and 2) by obtaining continuous metrics (gyrification index and curvedness index) using FreeSurfer. A chi-squared test revealed that the degree of HG folding was not different across the four groups. A linear mixed-effects model (controlling for the effects of age, hemisphere, and scan location), similarly showed no effects of group on the gyrification index or the curvedness index. To conclude, my findings show that blindness does not affect HG gyrification. The results challenge the idea that auditory experience alters HG structure and offer important insights into previous findings in professional musicians. Our results suggest that the prevalence of duplicated HG in musicians may be the result of individuals with larger processing capacity within the auditory cortex being more likely to take up music as a profession.

There is a growing emphasis on providing "equitable" mental health care, and yet ‘equity’ is seldom defined clearly. Publicly-funded community mental health clinics’ (CMHCs) clinicians often serve clients from minoritized and underrepresented backgrounds, and thus may regularly observe and address equity issues, making their perspectives invaluable. This qualitative study explores CMHC clinicians’ perspectives of equity in their clinical practice. Our data was obtained from an online cognitive-behavioral therapy (CBT) training initiative in Washington State targeting CMHC clinicians serving youth. Participating clinicians (N = 245) received nine consultation sessions from CBT experts over a six-month period and completed pre-training and post-consultation surveys. In the pre-training survey, we asked clinicians to define equity and list resources they would want access to that can improve their consideration of equity in their practice. Descriptive statistics summarized clinician demographics. Using thematic analysis, clinicians’ open-ended responses were coded to identify emerging themes. Clinicians were predominantly female (74.7%), White (58.8%), had a master’s level training (90.2%), and a mean age of 34.2 years (SD = 9.3). After coding clinicians’ definitions of equity, ‘accommodation’ (i.e., tailoring services to clients) was the most endorsed theme (38.8%, n = 95), followed by ‘equality’ (i.e., treating clients the same; 19.6%, n = 48) and ‘fairness’ (i.e., treating clients with justness, 17.6%, n = 43). When asked about resources that could improve their considerations of equity, clinicians’ responses most frequently included diversity, equity, and inclusion (DEI) trainings, expanding reach to more diverse populations, equity-focused supervision, and financial aid (e.g., gas cards, food pantry). While CMHC clinicians’ perceptions of equity included common themes, their understanding may at times conflate equity and equality. These findings highlight the importance of increasing access to DEI-focused trainings and supervision along with other resources to assist CMHC clinicians in delivering equitable care.

The Manduca sexta hawkmoth, a proficient pollinator, employs its antennae to efficiently navigate its surroundings. With their antennas highly developed olfactory sense as well as their wide range of odor recognition using their sensory receptor cells, moth antennae are an ideal candidate for developing reliable biosensors. In contrast, commonly used artificial sensors are inefficient and inaccurate in chemical detection. Furthermore, their manufacture is challenging due to their inconvenient design for the user. To evaluate the antenna's effectiveness as a biosensor model, we assessed neural activity in the moth antenna by means of an electroantennogram (EAG). To do this, we attached the removed antenna to a circuit to amplify and measure voltage variations across the antennal nerves during odor stimulation. We then placed the circuit into a wind tunnel and administered a selection of odorants over a determined cycle of durations ranging from 0.2, to 10 seconds. The odorants included a floral mixture from Datura flowers and a certain compound in the mixture (linalool) known to be attractive to moths, as well as volatile organic chemicals (VOCs) replicating both healthy and COVID breath. Our findings show strong initial spikes of electrical activity in the receptor cells correlating to odorant release​, favoring the shorter durations and both the floral mixture and linalool. Prolonged exposure (5 and 10 second durations) to odorants caused continuous increased activity in the antennae, with a more pronounced response observed in the COVID VOCs and linalool. These results demonstrate that moth antennas are a suitable model for the construction of highly accurate and efficient biosensors, and support the feasibility of implementing them in devices aimed at detecting and identifying substances of interest. Future work will explore additional COVID-associated compounds and apply data to an algorithm for machine learning software to enhance capabilities for disease diagnosis.

In recent years, organizations have increasingly expressed support for efforts to promote diversity, equity, and inclusion (DEI). Some of these efforts are informed by research on how to promote DEI, but much of this research on how to communicate and promote DEI in organizations fails to account for qualities of the communicator, that is, the diversity specialists charged with operationalizing and implementing DEI sentiments to improve organizational equity and inclusion. Critically, communicators bring their own social identities (e.g., gender, race) and experiences (e.g., status, power) to their work. This proposal aims to better understand how DEI personnel in the public sector experience their roles, understand their jobs and their ability to effect change, as well as consider how their personal identities interact with their work. We are conducting semi-structured interviews with DEI management personnel across cities in Pacific Northwest states (Washington, Oregon, Idaho, and Alaska). Participants will be asked about their perceptions of their job responsibilities as well as their backgrounds and identity. We will be coding interview responses to examine the pressures that individuals feel in their jobs, constraints they experience in how they can advocate for DEI as a function of their social identities, how they conceptualize and communicate the importance of DEI. By better understanding the daily experiences of implementing DEI practices in organizations, this proposal aims to improve our understanding of efforts to improve DEI in public organizations.

While research on burnout has focused specifically on service-oriented roles (e.g., healthcare), recent trends indicate a growing prevalence of burnout in academic settings. Burnout syndrome (BS) is a set of psychological symptoms arising from interplay of chronic occupational stress and individual factors. These symptoms often manifest as emotional exhaustion, depersonalization, and diminished professional satisfaction. Academic burnout has become a concern due to its association with poor academic performance, dropout rates and mental health symptoms (e.g., depression & anxiety). This study employed a pre-and post-design, assessing burnout before and after a burnout management workshop. An online survey via Qualtrics gathered data from community college students in the Pacific Northwest (N = 28, primarily women (78%), aged 16-20 (63%), including dual enrolled high school students. The survey employed a revised Purdue Burnout Questionnaire and collected demographic information. The burnout management workshop, facilitated by two psychology faculty members, addressed burnout facets and various management techniques. We hypothesized that participating students would show improvement after attending the workshop. Initial analysis revealed a reduction in total burnout scores before and after the workshop. Despite a noteworthy decrease, the change did not reach statistical significance. This nonsignificant trend suggests a positive direction, and further qualitative data, scheduled for collection in Spring 2024. Understanding and addressing academic burnout is crucial as it directly correlates with students' academic performance and mental health. By examining burnout in the college setting, we hope to contribute valuable insights that can inform policies and interventions to create a more supportive academic environment.

Burnout presents a significant challenge for mental health clinicians, affecting not only their well-being and turnover rate but also the quality of care provided to clients. Moreover, studies have shown that clinicians working in community settings face more burnout compared to those in private practice. Among the factors that have been implicated in clinicians’ burnout are the level of education, limited experience and training opportunities, individual variables, and demographic factors. In this study, I examined how clinicians’ reported competencies in core cognitive behavioral therapy (CBT) skills for treating anxiety, depression, trauma, and behavioral concerns are associated with their experiences of burnout. I further evaluated whether the relationship between competencies in core CBT+ skills and experiences of burnout is moderated by CBT+ training. The study draws on a diverse sample of 200+ community mental health clinicians who took part in Washington State’s CBT+ training initiative. I employed t-test and multiple regression models to analyze the data. Based on these analyses, there are anticipated insights of uncovering clinician experiences in how clinicians’ level of CBT skills and professional training experiences intersect with burnout. Findings are expected to inform targeted interventions aimed at reducing burnout and enhancing clinician retention across the workforce.

Ewing sarcoma (EwS) is the second most common bone cancer in children and young adults, which also arises in soft tissue, characterized by the fusion of FET and ETS genes, with EWS::FLI1 being the most common fusion protein. Menin, a protein encoded by the MEN1 gene, is a scaffolding protein that can activate or repress transcription depending on its binding partners. Menin plays an oncogenic role in EwS, but the precise mechanism remains to be elucidated. To investigate the role of menin in tumorigenesis, we first examined whether menin directly modulates the protein and transcript levels of the driver of EwS, EWS::FLI1. We generated whole cell extracts from MEN1-knockout (KO) and control cell lines and used western blotting to determine the EWS::FLI1 protein levels. These results showed that the loss of menin led to an increase in EWS::FLI1 for some of the MEN1-KO cell lines. RNA was purified from the MEN1-KO and control cell lines to assess the levels of EWS::FLI1 mRNA by RT-qPCR to determine if menin modulates EWS::FLI1 transcript levels. We are currently examining menin’s role in modulating essential histone modifications, specifically H3K4me3 at promoters and H3K27Ac at enhancers since menin modulates the activity of histone-modifying enzymes. We generated nuclear extracts under high salt conditions to extract histones from chromatin in MEN1-KO and control cell lines. To assess the success of the fractionation of the nuclear and cytoplasmic proteins, we conducted a western blot analysis to confirm the histones were extracted exclusively in the nuclear fraction. The levels of H3K4me3 were lower in some MEN1-KO cell lines, suggesting menin may have a role in epigenetic regulation in EwS. By understanding menin’s role in modulating EWS::FLI1 levels and global histone modifications, we may identify potential drug targets for future cancer treatments.

Current research on substance use suggests a positive correlation between emotion dysregulation and cannabis misuse or cannabis use disorders (CUD). This study aims to identify which specific facets of emotion dysregulation increase CUD symptom severity. While previous studies using the Difficulties in Emotion Regulation Scale (DERS) have linked overall composite scores of emotion dysregulation to CUD, there is a gap in the understanding of how individual DERS subscales relate to CUD, which limits our ability to develop targeted interventions. Young adults (N=68, Mage=23.7 years, SD=3.05, 54.4% female, 63.2% White) who reported using cannabis 2-3x/week or more in the past month completed measures of emotion dysregulation (DERS) and CUD (Cannabis Use Disorder Identification Test; CUDIT). To test associations between the 6 DERS subscales and CUDIT total score, we will first conduct bivariate correlations. If significant associations are found, we will conduct a multiple linear regression model to test which subscales best predict CUDIT total score. We hypothesize a moderate-to-strong correlation between the DERS and CUDIT scores, with Nonacceptance and Impulse control demonstrating stronger correlations. We also hypothesize that Nonacceptance and Impulse control subscales will most strongly predict CUDIT total scores. Results from the present study could help identify which of the emotion dysregulation subtypes should be targeted in future prevention and intervention efforts for young adults. If these findings are supported, additional efforts may want to teach skills to increase acceptance of emotional responses and improve impulse control. The proposed study is an important step in the treatment of cannabis misuse and CUDs as we will be able to narrow our aim toward isolated treatments to improve the livelihood of those involved.

Adolescents increasingly use digital technology. However, there might be variability in how important adolescents perceive their interactions with media and technology 1) to bridge online and offline experiences, 2) to go outside one’s identity or offline environment and 3) for social connection. This study aims to validate the Spanish version of the Adolescent Digital Technology Interactions and Importance Scale (ADTI), originally developed for US adolescents, with a sample of Peruvian adolescents. In addition, we investigated developmental and gender differences in these subscales. A total of 1,425 Peruvian adolescents (10 - 17 years, Mage = 13.2; 52% female) completed the ADTI remotely via Qualtrics in April 2020, a few weeks after adolescents had started remote schooling. I ran descriptive statistics and linear regressions to test for age and gender differences. Factor 1 (bridging online and offline experiences) was the highest ranked M = 15.1 (5), followed by Factor 2 (going outside one’s identity or offline environment), M = 14.2 (4.6). Factor 3 (social connection) was the lowest ranked M = 12.6 (4.5). Age was significantly correlated with Factor 1 and Factor 3 indicating that older adolescents endorsed higher levels of importance of technology for bridging online and offline environments as well as social connection. There was no significant age difference for Factor 2. We investigated gender differences. Girls had significantly higher levels for Factor 1 compared to boys Mgirls = 15.4 (4.7); Mboys = 14.7 (5.2) and for Factor 3 Mgirls = 13.4 (4.6); Mboys = 11.9 (4.3). There were no significant gender differences for Factor 2. This work can lead to better understanding of the role that technology plays in the lives of adolescents, and to implementation of safer practices in media and technology.

This poster describes a qualitative study highlighting the intersection of ethnic identity and Christian faith in shaping South Asian college students’ perceptions of LGBTQ+ individuals. Current sociopolitical climates toward LGBTQ+ individuals in South Asian countries tend to be hostile, and even South Asian communities within the United States can reflect similar beliefs. Zaidi (2014) found that shame in the South Asian community was in conflict with a desire to express one’s queer identity among South Asian youths (Zaidi, 2014). Moreover, environmental factors such as the religious setting might contribute to varying perspectives regarding LGBTQ+ individuals; in the current study, we highlight faith-based higher education institutions (i.e., Christian university) as an institution that can shape views regarding LBTBQ+ folks and their experiences. We conducted 6 semi-structured interviews with South Asian college students enrolled in a Christian university located in the Pacific Northwest region of the U.S. Our three-member research team transcribed the interviews, coded the transcriptions, and placed the codes in themes according to Braun and Clarke’s (2006) guidelines for Thematic Analysis. The four themes that we identified include support for LGBTQ+ people on campus, Christian messaging around LGBTQ+ identity, South Asian communities, and participant’s own attitudes. These major themes also included subthemes, some of which are campus advocacy and protests influenced participant’s beliefs, feelings of an internal struggle, attitudes of South Asian communities, and individual affirming attitudes. Broadly, we found that the participants viewed their own South Asian communities as generally silent or passive in LGBTQ+ dialogues, and that their Christian campus promoted both helpful and unhelpful conversations about the topic. We will present some implications for practice in higher education around fostering an inclusive space for LGTBQ+ individuals, especially as they pertain to intentional integration of culture-specific (e.g., South Asian) and religious (e.g., Christian) perspectives.

We looked at the effect of age on location discrimination and reversal learning in horses. In location discrimination the animal learns to select a reinforced location and ignore other unreinforced locations. In reversal learning, the reinforced and unreinforced locations are switched. Research with humans and animals has found that while age has no effect on initial learning, older animals show impaired reversal learning since this task requires greater cognitive flexibility. Based on this information, we predicted that older horses would learn the location discrimination as quickly as younger horses, but would show impaired reversal learning due to age-related cognitive decline. We recruited 27 horses aged 5-27 years from Overlake Farm in Bellevue. All horses learned to discriminate between two locations, approaching a location that had a pan with food more quickly than a location with an empty pan. We then examined reversal learning by switching the location of the pan with food and the empty pan. As predicted, compared to younger horses (aged 5-17 years), older horses (aged 18-27 years) learned the location discrimination task as quickly as younger horses, but showed impaired reversal learning, primarily as a result of their inability to inhibit previously reinforced approach responses. Horses showed signs of frustration and aggression during reversal trials, so we conducted a systematic analysis of anticipation and frustration behaviors for 15 horses that participated in 2023. We predicted that they would show positive food anticipation behaviors when approaching reinforced locations, and frustration behaviors when approaching previously but no longer reinforced locations during reversal trials. This research is the first to explore the behavioral indicators related to cognitive processes involved in reversal learning, and these tests of cognitive flexibility serve as a potential use for future diagnoses of cognitive decline in older humans and animals.

Sound symbolism is a phenomenon wherein the phonetic forms of certain words iconically represent attributes of the objects, qualities, or events they describe. This study focuses on the sound-meaning link in Panãra animal names, using vocabulary from field notes collected in the Panãra community by Dr. Lapierre the summers of 2015-19 and by Dr. Lapierre and PhD students Ananthanarayan, De Falco, and Jeter the summer of 2023. The Panãra vowel system has a combination of features not present in some more widely studied languages such as English, namely, a back, unrounded series, contrastive length, and contrastive nasality. Using this extensive inventory, I assess strength of size sound symbolism created by nasality, height, vowel length, and backness, as well as the interactions between multiple features. I organize Panãra names for different animals and find the average weight of that species. I calculate the percentage of vowels that have a certain feature in a word and assess the correlation between this percentage and the weight of the species denoted using a regression model. Previous research has shown that front and high vowels are associated with smaller sizes and back and low vowels with larger sizes. I predict that the phonetically central and mid series will be associated with sizes intermediate to the peripheral series. Alongside providing observations from an under-documented language regarding its sound symbolism, findings from this study will help guide the continued lexicographic and field research inquiries into the Panãra language.

Plainfin midshipman (Porichthys notatus) are seasonally reproducing teleost fish found along the Pacific Coast of North America. During the non-reproductive months (December-February), midshipman live offshore in deep waters. Between March and July, they migrate to the intertidal zone to reproduce. During the reproductive period, dominant (type I) males build and defend nests and hum to attract female mates. Unlike most vertebrates, courtship (humming to attract mates) and parental care (egg cleaning, nest defense) are both conducted only by type I males. These males therefore face energetic and temporal trade-offs between courtship to parental care within a single reproductive season. Our research investigates the neural mechanisms underlying the transition from courtship to paternal care in type I males during the reproductive period. We propose that this behavioral shift is regulated by steroid hormones (i.e. testosterone and estrogen) and neuropeptides (i.e. galanin). We are measuring hormone levels in blood and brain of midshipman fish across various conditions of courtship and parental care. We show the relationship between changes in steroid and neuropeptide levels in both blood and brain and changes in courtship and parental care behavior in type I males. Understanding these mechanisms in midshipman fish is crucial, as the steroid and neuropeptide pathways that regulate social behaviors share similar pathways across vertebrates. Therefore, studying this in teleost fish can provide valuable insights into the broader regulatory mechanisms of reproductive life-stage transitions in vertebrates.

Smartphone use among adolescents has dramatically increased in the past decade, with adolescents allocating more time inside on their screens and less time outside in nature. Given these shifts in behaviors, there has been a rise in concerns about the impact of smartphones on adolescents’ mental health. Studies on nature exposure have found that spending time in nature promotes human well-being; however, a limited body of research exists exploring how smartphone use impacts our ability to experience these physical and psychological benefits of nature exposure. To address this gap in the literature, we conducted a between-subjects experiment with college students at the University of Washington (N ~ 40) randomly allocated to one of two conditions to spend 20 minutes in nature: a smartphone condition and a no-smartphone condition. Participants self-reported on positive and negative affect and rumination before and after their experience in nature. After completing these scales, participants reported on their experience of Presence, a state of being in which the mind is highly aware but without active thought, by self-reporting on a recently validated 14-point scale and writing about it for further analysis using an interaction pattern approach. I anticipated that participants who feel more attached to their smartphones spend more time using them in nature and, in turn, are less likely to experience the emotional benefits of nature. If the findings reflect this, future research should explore how smartphones impact adolescents’ mental health and the extent to which smartphone-free time spent outside in nature can improve their well-being.

People are more likely to stigmatise the mental health of an out-group compared to an in-group member. People are also more likely to distribute resources toward in-group than out-group members. The present study applies these findings to understand how likely a person is to appraise another’s mental health experiences as legitimate and share mental health resources with them based on identified social groups. Participants recruited from the University of Washington Psychology Department subject pool were randomly assigned to one of four different conditions. They read a vignette about a hypothetical individual with or without a specified diagnosis of OCD who attends the University of Washington or Washington State University. The participants reported their legitimacy appraisal of the outlined mental health challenges and their willingness to share mental health resources with the target. I hypothesise that participants who read a description of an individual from Washington State University without a specified diagnosis will rate the individual’s mental health condition as less legitimate. I also hypothesise participants who read about an individual from Washington State University without a specified diagnosis will be less likely to share mental health resources with them. The findings of this study will help shed light on the type of stigma surrounding mental health and resource sharing from the perspective of social groups. In turn, the findings can help the public recognise more acute mental health biases they may hold and thus work towards dismantling them. This can foster the growth of a more empathetic and united community.
