Young adults’ mental health has emerged as a critical public health concern, with rising rates of sleep deprivation reported over the past decade. Online video gaming has become a popular bedtime activity, especially among undergraduates, and may contribute to their sleep disruptions and daytime mental health malfunctions. However, not all undergraduates experience bedtime online gaming in the same way, and understanding who is most vulnerable, under what conditions, and whether bedtime online gaming may have neutral or even protective effects for some individuals remains a critical gap. Besides the importance of exploring individual differences in such effects, many studies rely solely on self-reported sleep quality, which can be biased or inaccurate.

To address these issues, this project will utilize a longitudinal data collection method. A total of 10 TCU undergraduates will be recruited through the campus gaming club. Over 14 days, participants will complete a morning survey assessing their prior night’s online gaming experiences and subjective sleep quality, and a brief tasks to measure cognitive functioning. Evening surveys will assess momentary mental health states and include an open-ended question about anything they want to share about their past day. Participants will continuously wear Garmin devices to collect objective sleep metrics passively. Findings will uncover the moment-to-moment impacts of bedtime gaming on sleep quality and overall functioning, and provide preliminary insights into individual differences in why and how some students are negatively affected by bedtime video gaming, while others may not be.

I expect that task performance will vary among participants based on individual gaming habits. Specifically, I anticipate a negative correlation between total bedtime gaming time and next-day performance on cognitive tasks, particularly when participants stay up late to game, leading to disrupted sleep. In such cases, deviations from typical healthy sleep patterns may negatively influence participants’ cognitive functioning. I also expect that the type of game played may influence outcomes, as games that involve higher levels of sensory stimulation and rapid decision-making (e.g., action shooters) may negatively affect sleep and further impair cognitive performance compared to slower-paced genres such as role-playing games.

Frustrative nonreward refers to the behavioral reactions that occur when an expected reward is reduced or omitted. Reward downshift procedures provide a useful framework to examine whether behavior is guided by current reward expectancies (action) or by learned stimulus - response associations (habits). Under conditions in which behavior depends on reward expectancies, animals typically adjust their responses when reward value changes. By contrast, if behavior has become habitual, original responses may persist even when the outcome is reduced. The present study examined whether extended training in a Pavlovian autoshaping task promotes habit-like responses following a reward downshift. In Experiment 1, rats were trained to respond to two levers associated with different reward magnitudes. Animals received either standard training (10 days) or extended training (30 days). After training, preference for the higher-value reward was assessed, and then one lever was downshifted to deliver the same smaller reward that the other lever provided. Changes in lever preference following the downshift were used to evaluate behavioral adjustments. Both groups initially adjusted their responses after the reduction in reward magnitude, through a change in preference from the downshifted to the unshifted lever. However, animals that received extended training gradually returned to their original preference for the downshifted one, even though both options delivered the same outcome. This persistence suggests the development of stimulus–response associations consistent with habit-like control. In contrast, animals that received standard training maintained a frustration induced change in preference after the downshift, indicating a weaker habit formation response. Experiment 2 tested whether overtraining by increasing the number of trials within each session would produce similar effects. Although animals received more trials per session, both groups showed similar behavioral adjustments following reward downshift and did not differ in preference patterns. Together, these results suggest that the development of habit-like responding depends not only on the amount of training but also on how experience is distributed over time. Training extended across multiple days, rather than concentrated within sessions, appears to promote persistent responding that is less sensitive to changes in reward magnitude.

Women remain disproportionately affected by human immunodeficiency virus (HIV), with disparities in acquisition risk research concentrated among Black women in the Southern United States. Although there are effective prevention tools such as Pre-Exposure Prophylaxis (PrEP), uptake of these tools remain low. This review analyzes the critical gap in prevention and protection against HIV in Black women. Systemic search of PubMed (2010-2025) was conducted looking for keywords such as “Women and PrEP”, “Barber Shop Model”, “Beauty Shop Model”, “Mobile Health Unit Health Care”, “PrEP Education”, and “Birth Control”. Reducing HIV disparities among Black women requires changing structural and social factors that influence the high HIV risk-factors. Awareness and self-perceived risk must be considered at the individual level in order to effectively prevent HIV acquisition. Existing research shows that the way prevention services are delivered and designed affect the efficacy of HIV prevention efforts. In addition to advancing biomedical strategies, interventions should be culturally responsive to increase awareness and reduce stigma surrounding PrEP and HIV. Overall, HIV disparities among Black women are multifactorial, and shifting prevention efforts into trusted community spaces while addressing the structural roots of medical mistrust shows a promising strategy for narrowing the gap in HIV prevention.

Resilience is the ability to cope with and overcome difficulties. Childhood traumatic events can undermine resilience by disrupting emotion regulation, coping skills, social connectedness, and self-esteem, thereby reducing an individual's ability to cope effectively. A commonly used metric for assessing these events is Adverse Childhood Experiences (ACEs), which examines exposure to abuse, neglect, and household dysfunction. One way to increase resilience is through a secure attachment to a caregiver. However, if an individual lacks a secure attachment to their caregiver, supportive relationships, such as natural mentors (NM; kin, non-kin, helping professionals), can also foster resilience. The present study examines whether having a NM is associated with higher resilience, while accounting for adverse experiences and insecure attachment to primary caregivers. Approximately 300 TCU students will be recruited to complete an online survey assessing ACEs, resilience, attachment to their caregiver, and any prior relationship with a NM. Descriptive analyses, one-way ANOVA, two-way ANOVA, and stepwise multiple regression will be conducted to examine associations. Descriptive analyses will examine the prevalence of all variables. Individuals with different types of NM mentors are expected to report different levels of resilience. Additionally, individuals with a NM are expected to demonstrate greater resilience when accounting for ACEs. Finally, the presence of NMs is expected to be associated with greater resilience compared to individuals without a mentor, even after controlling for insecure attachment. Data collection will begin in March 2026 and continue throughout the month, with results and implications being presented at the conference.

Cytokines are a protein involved in the body’s inflammatory response to pathogen threats (Danzter, 2001), and there is evidence that long-term oral contraceptive use can increase generalized inflammation (Mongiovi et al., 2025). Sickness symptoms are related to higher cytokine levels (Dantzer & Kelley, 2007), and further research found that participants who experienced more sick effects (injection-site soreness, fatigue, muscle aches, etc.) post-flu shot showed higher cytokine levels than those with less intense sick effects (Christian et al., 2015). We wanted to know if there is a difference in post-flu shot cytokines levels and sick symptoms between naturally cycling women vs. women on hormonal birth control (HBC)/ We also wanted to know if there is a relationship between phase of menstrual cycle and levels of inflammation after a flu shot. To answer these questions, we recruited 47 women from the TCU flu-clinic. The morning after their flu shot, participants gave a blood-spot samples (stored on Whatman 903 protein saver cards), completed a survey on their HBC use, menstrual cycle phase, GRIT, mood and feelings, and sick symptoms. The data are currently undergoing multi-variate analysis, where birth control use (naturally cycling vs. HBC use) and menstrual cycle phase are the predictor variables, and cytokine levels, sick symptoms, GRIT, and mood and feelings are the dependent variables. Blood spot samples will be analyzed in May 2026 using Mesoscale Discovery V-Plex assay kits. We expect to find a relationship between HBC use and cytokine levels, and sick symptoms and cytokine levels. We also expect to find a relationship between HBC use and GRIT, mood and feelings, and sick symptoms. We do not have any expected outcomes for the relationship between menstrual cycle phase, cytokines levels, and sick symptoms, as this research is exploratory.

People with obsessive-compulsive disorder (OCD) tendencies experience intrusive, uncontrollable thoughts and images that elevate anxiety. These tendencies could potentially influence time perception, which is the subjective experience of time passage. Time scarcity is the feeling that you don’t have enough time to complete tasks. In contrast, time affluence is the feeling that you have more than adequate time to complete tasks. Research has shown that time affluence is positively associated with meaning in life, while time scarcity has a negative association with meaning of life. This study examines how OCD tendencies influence the relationship between time perception and meaning in life. Participants (N = 360) were recruited from Prolific and were randomly assigned into 1 of 3 conditions (i.e., time scarcity, time affluence, vs. control). Following the completion of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) to measure OCD traits, participants underwent a manipulation by reading a vignette that primed them about the tightness or openness of time in a work environment. After the manipulation, participants completed the Meaning in Life Questionnaire. This research will guide future work on how time-scarce or time-affluent environments affect OCD symptomology.

Stigma is a pervasive issue in society, with stigmatizing language describing individuals with substance use disorder (SUD) negatively impacting coping effectiveness, treatment-seeking, and interpersonal relationships (Luoma et al., 2008). Previous research has found that labeling individuals with SUD is associated with public fear and desire for minimal social contact (Link et al., 1999). Additionally, stigmatization of this population has been associated with reduced support for public health policy and greater support for punitive policies (Kennedy-Hendricks et al., 2017). The current study examined whether the language used to describe an individual with SUD affects perceptions of social distance and support for treatment. Community members in Tarrant County were approached in public areas and invited to participate in a survey regarding individuals with SUD. Participants were randomly assigned to read one of two different vignettes written in either person-first language or stigmatizing language, then completed survey questions via tablet or QR code. We hypothesize that participants reading stigmatized language will report greater desired social distance from the individual with SUD and display less support for treatment engagement. These findings would suggest that efforts to reduce stigmatizing language in public discourse, such as media campaigns, healthcare training, and policy reform, are critical to fostering more supportive attitudes toward treatment and recovery for individuals with SUD.

Throughout history, pathogens have posed a major threat to human survival. In response, humans have developed both physiological and behavioral defense mechanisms, including the immune system, which helps combat infections. Disgust serves as a crucial defense, preparing the body for exposure to potential pathogens before they enter the body. Since internal state changes redirect energy toward immune activity and healing, inflammatory responses may also influence willingness to exert effort in various contexts. This study examines how disgust affects effort exertion for rewards or to avoid costs. We hypothesize that disgust increases inflammation, which in turn reduces willingness to exert effort. We propose that this shift is driven by energy conservation due to an inflammatory response, rather than a reduced desire for rewards or avoidance of costs. Participants will be exposed to disgust-inducing stimuli while inflammatory markers (core body temperature, heart rate, and blood cytokines) are measured. Their willingness to exert effort for rewards or to avoid costs will also be assessed. Findings may offer insights into adaptive decision-making, clarifying how an immune response triggered by disgust impacts motivation and effort allocation. 

Anxiety sensitivity (AS) refers to the fear of bodily sensations typically associated with physiological arousal. High AS is a transdiagnostic predictor of poor mental health outcomes, such as panic disorder, other anxiety disorders, post-traumatic stress disorder, and overall functional impairment. Individuals with high AS may exhibit body hypervigilance, and in turn, be more likely to experience psychosomatic symptoms. A State of Surrender (SoS) refers to one's ability to accept what is to come without resistance and relinquish control. It has been associated with greater well-being, and preliminary data suggests it is negatively associated to anxiety and AS, mediated by distress tolerance. To further test this, we will recruit individuals on Prolific and randomly assign them to either a surrender-based meditation protocol or a control condition. We will measure functional somatic symptoms, trait anxiety, distress tolerance, self-efficacy, and anxiety sensitivity. We predict that individuals in the experimental condition will endorse less AS, mediated by self-reported SoS. We also predict that the effect will be greater for individuals with more somatic symptoms. Findings will suggest further exploration of acceptance-based treatment for individuals with high AS and other psychosomatic complaints.

Youth involved with the juvenile justice system are disproportionately exposed to trauma, family stressors, and environmental obstacles. Although family dysfunction, emotion dysregulation, and caregiver strain have been studied in relation to youth delinquency, there’s a gap in the research examining the interaction between these three factors among families with youth involved in the juvenile justice system. Shaped by Bowen’s Family Systems Theory and Social Learning Theory, this study explored triangular associations among emotion dysregulation, family dysfunction, and caregiver strain.
Baseline data were drawn from the parent study, Leveraging Safe Adults (LeSA), which drew 220 youth and their caregivers from nine juvenile detention centers across Texas and Illinois. Among other measures, the youth completed the Difficulties in Emotion Regulation Scale (DERS) and the Youth Family Assessment Device (Y-FAD), while the caregivers completed the Caregiver FAD (C-FAD) and the Caregiver Strain Questionnaire-Short Form (CGSQ-SF). Analyses examined correlations among the three factors.
Results indicated a moderate, statistically significant positive correlation between C-FAD and CSQ, but no significant relationship between Y-FAD and CSQ. The relationship between CSQ and DERS was small, but not statistically significant. Both Y-FAD and C-FAD were related to higher DERS reports.
By analyzing emotion dysregulation, family dysfunction, and caregiver strain reciprocally and interdependently rather than in isolation, this study helps to provide a better understanding of the objective socioemotional processes of and between youth and their families involved in the juvenile justice system. It also highlights the importance of incorporating both youth and caregiver perspectives into study design and assessments.
