During ancestral times, while women focused on child-rearing, they relied on their male mates to protect their family. Nowadays, women can protect their families themselves by employing strategies like using a home security system or owning a firearm. However, modern women continue to form long-term relationships with men to reduce the risk of encountering harm (Wilson & Mesnick, 1997). Crucially, men will not provide investment without getting something in return. One resource that men value that women can provide in exchange for investment is granting men sexual access (Baumeister & Vohs, 2004). Therefore, given that women continue to use men as a protective resource and men will accept sexual access in exchange, we should find that women in dangerous environments are more sexually open. This study aims to examine the impact of dangerous environments on women’s sexual strategies. Importantly, no previous research has focused on this. Overall, I predict that women who are primed with dangerous environment cues, compared to women who are primed with a control condition, will show higher levels of sexual openness. By gaining more knowledge about how dangerous environments can influence women’s mating strategies, we can better understand how evolutionary mechanisms continue to influence women’s sexual behaviors. Data are forthcoming.

A Qualitative Analysis of Barriers and Facilitators to Care Engagement: Staff and Client Perspectives on the ACTION Intervention

Author(s): Morayma Rodriguez Psychology
Advisor(s): Kevin Knight Psychology Stephanie Villaire Psychology

Many barriers to accessing treatment for substance use disorder and HIV among those on community supervision are well-documented, including a lack of transportation, lack of reentry care, and lack of awareness of services. To address these barriers, a NIDA-funded R01, ACTION, aimed to promote engagement in care for infectious diseases (like HIV/AIDS) and opioid use disorder for individuals on probation in Texas. When conducting these large studies, it is imperative to understand participant and staff perceptions of an intervention’s feasibility and acceptability. Therefore, the current study aims to analyze the similarities and differences in opinions and attitudes of the success of the intervention identified by project staff and client. To examine this, a deductive qualitative analysis of 6 project staff and 20 clients was completed using Atlas.ti. Staff identified communication, state resources and facilities, and issues with pharmacies as key barriers to the intervention, whereas clients cited scheduling and transportation as key barriers. Staff identified the ability to communicate with other staff for resources, meeting clients in person, and meeting in the mobile health unit as key strengths of the intervention, whereas clients cite receiving healthcare services and interaction with the patient navigator and research assistant as key strengths. Understanding these barriers to and facilitators of the ACTION interventions allows researchers to see what works and what can create issues in the study.

Game on or Game over? The Effects of Bedtime Online Gaming on Sleep Quality, Next-Day Cognitive Performance and Mental Health Outcomes

Type: Undergraduate
Author(s): Ian Sanchez Psychology
Advisor(s): Qinxin Shi Psychology

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.

Effects of Overtraining on Behavioral Adjustment to Reward Downshift

Type: Undergraduate
Author(s): Catalina Sheehan Psychology
Advisor(s): Mauricio Papini Psychology

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.

The Impact of Helicopter Parenting and Interparental Conflict on College Students' Romantic Relationships: The Mediating Role of Attachment-related Behaviors

Type: Graduate
Author(s): Whitney Sullivan Psychology Ava Burton Psychology Jasmine Durrant Psychology
Advisor(s): Naomi Ekas Psychology

The term helicopter parenting (i.e., parents’ over-involvement in the lives of their child) has been used to describe parents who exercise increased involvement and control over their child and is mostly regarded as developmentally inappropriate for emerging adults (Kouros et al., 2017; Padilla-Walker & Nelson, 2012). The association between helicopter parenting and poorer relationship satisfaction in college students has recently been observed (Jiao et al., 2024). Interparental conflict has been associated with poor relationship quality in emerging adults (Parade et al., 2012; Singh & Thomas, 2023). In addition, studies have indicated that interparental conflict and helicopter parenting predict negative attachment characteristics in children (Laurent et al., 2008; Miller et al., 2024). The goal of the current study was to examine the associations between helicopter parenting, interparental conflict, and parenting warmth on college students’ relationship satisfaction. An additional goal of the current study was to examine the extent to which negative attachment-related behaviors (i.e., anxiety and avoidance) explain these associations.

Participants included 413 undergraduate students in a romantic relationship who were enrolled in psychology courses across two private universities in the Dallas-Fort Worth area. Students completed a series of questionnaires through an online survey platform in exchange for course credit. Measures used for the current study included the Consolidated Helicopter Parenting Scale (CHPS; Schiffrin et al., 2019), the Conflict Properties subscale of the Children's Perception of the Interparental Conflict Scale (CPIC; Grych et al., 1992), the Parental Bonding Instrument (PBI; Parker et al., 1979), the Experiences in Close Relationships (ECR; Miller et al., 2024), and the Couples Satisfaction index (CSI; Funk & Rogge, 2007).

A structural regression model was conducted using structural equation modeling (SEM) in MPlus (Muthén & Muthén, 2017) to examine the associations between relationship satisfaction and parenting behaviors as well as interparental conflict mediated by level of attachment-related anxiety and avoidance. Significant negative associations were observed between relationship satisfaction and conflict properties (b = -.09 (SE = .05), p = .050), and level of attachment-related anxiety (b = -.19 (SE = .05), p ≤ .001) and avoidance (b = -.49 (SE = .04), p ≤ .001). Direct associations between relationship satisfaction and helicopter parenting as well as parental warmth were non-significant (ps ≥ .206). Significant positive associations were observed between attachment-related anxiety and helicopter parenting (b = .33 (SE = .05), p ≤ .001) and conflict properties (b = .17 (SE = .05), p = .001). Helicopter parenting was positively associated with attachment-related avoidance (b = .19 (SE = .05), p ≤ .001). All other effects were non-significant, ps ≥ .119.

Findings of the current study indicate that helicopter parenting behaviors increase negative attachment-related behaviors (i.e., anxiety and avoidance) in college students, which, in turn, decreases their relationship satisfaction with their current romantic partner. Interparental conflict negatively impacts college students’ relationship satisfaction. Parental warmth does not impact college students’ attachment-related behaviors or their relationship satisfaction. A strength of the current study is a large sample size well-powered for conducted analyses. Limitations include use of self-report measures and a non-representative sample as most participants were White females. Future research should examine these associations over time as well as include the use of observational measures. Clinicians working with college students with helicopter parenting and interparental conflict experiences should implement interventions designed to strengthen positive attachment-related behaviors.

The Link Between Natural Mentoring and Resiliency in the Face of Adverse Experiences and Insecure Attachment

Type: Undergraduate
Author(s): Jessie Swartz Psychology Lillyan Shelley Psychology
Advisor(s): Danica Knight Psychology

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.

Birth control, cycle phase, and inflammatory response to an immunological stimulus

Type: Undergraduate
Author(s): Emma Tawadrous Psychology Alexandra Hock Psychology
Advisor(s): Sarah Hill Psychology

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.

Meaning in Life and Time Perception: The Moderating Effects of Obsessive Compulsive Tendencies

Type: Undergraduate
Author(s): Roselyn Tentzohua Psychology
Advisor(s): Cathy Cox Psychology Bao Han Tran Psychology

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.

No time for meaning: How time scarcity impacts our meaning in life.

Type: Graduate
Author(s): Bao Han Tran Psychology
Advisor(s): Cathy Cox Psychology

Eighty percent of Americans feel like they "never have enough time." This phenomenon is referred to as time scarcity, or the feeling that we do not have enough time to do all that we want. According to Self Determination Theory, people need to feel like they can act in accordance to their values (autonomy), are able to master their environment (competence), and connect with others (relatedness) in order to thrive. It is hypothesized that when time feels restricted, our sense of autonomy,  competence, and relatedness is reduced. This study examines how time scarcity affects our meaning in life through the mediation of basic psychological needs. Two-hundred and thirty-six participants completed an online survey about time scarcity, time affluence, basic psychological needs, and meaning in life. Parallel mediation analyses reveal that time scarcity reduces autonomy and competence, which in turn reduces meaning if life, while time affluences increases autonomy and competence, which in turn increases meaning in life.

Disgust, Inflammation, and Effort: Investigating the Immune System's Role in Motivation and Decision-Making

Type: Undergraduate
Author(s): Emma Wilner Psychology Talia Chachkes Psychology
Advisor(s): Sarah Hill Psychology

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. 

Inducing a State of Surrender: Effects on Predictors of Panic Disorder Symptoms

Type: Undergraduate
Author(s): Michael Wrucke Psychology
Advisor(s): Cathy Cox Psychology Thomas Sease Psychology

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.

Decoding Digital Dynamics: An Intensive Longitudinal Study of Smartphone Use, Physiology, and Mental Health in College Students

Type: Graduate
Author(s): Zili Zhong Psychology
Advisor(s): Qinxin Shi Psychology

Emerging adulthood is a critical developmental period marked by increased independence, elevated social stress, and heightened susceptibility to mental health challenges. While digital device use is deeply embedded in their daily lives, its dynamic relationship with physiological functioning and mental health remains scare. Traditional retrospective self-reports cannot capture the objective, real-time, and complicate interactions between these factors. With the Ecological Momentary Assessment (EMA) and passive sensing techniques, we can overcome these obstacles and reveal the interactions between these factors in daily life.
This prospective, observational study aims to investigate the associations between phone use, physiological functioning, and mental health wellbeing among college students. Specifically, we aim to: 1) identify smartphone usage and physiological functions associated with between-person differences in mental health symptoms; 2) evaluate concurrent associations between individuals’ smartphone usage, physiological functions, and mental health symptoms; and 3) evaluate the time-lagged, mediating pathways of physiological functions (sleep duration and HRV) between smartphone use and next-day mental health symptoms.
We propose the recruitment of 100 undergraduate students aged 18-22 for a 28-day intensive longitudinal study. At baseline, participants will complete demographics survey and a series of assessments regarding their mental health. After the study takes place as physiological function (e.g., blood pressure, HRV, sleep quality, etc.) will be continuously measured via wearable devices Garmin Vivoactive Smartwatch. Digital behavior will also be measured via AWARE framework app installed and activated in the background of participants’ smartphones to passively record screen time and app use patterns. EMA will be provided 3 times a day (9am, 1pm, 6pm) to capture participants’ daily mental health. At the end of the 28-day period, a post-study assessment will re-administer mental health measures to evaluate change over time.
We anticipate specific digital and physiological patterns in distinguishing individuals' symptoms. First, at the between-person level, higher average daily screen time and greater evening smartphone use will be associated with elevated depressive and anxiety symptoms, while better physiological functioning, such as higher HRV and sleep quality, will be associated with alleviated depressive and anxiety symptoms. Second, at the within-person, concurrent level, days characterized by increased smartphone use and lower HRV will associate with higher stress and negative affect. Third we hypothesize a significant time-lagged mediation that elevated social media use will predict HRV and disrupted sleep, which in turn will prospectively predict (acute stress, negative affect, and depressive level) the following day.
Such findings will inform the development of scalable, data-driven models for early risk detection and support the creation of just-in-time intervention strategies to improve mental health outcomes for college students.

Family Dysfunction, Youth Emotion Dysregulation, and Caregiver Strain Among Families of Youth Involved in the Legal System (YLS)

Type: Undergraduate
Author(s): Hampton Zidlicky Psychology
Advisor(s): Danica Knight Psychology

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.

Reward downshifts show that behavior remains dependent on reward expectancies even after extended training

Frustrative nonreward (FNR), an adverse reaction brought on by unexpected reward reductions or omissions, can be induced by a downshift in the quantity or quality of the reward. The consummatory successive negative contrast (cSNC) task is a well-known paradigm for studying FNR. cSNC involves monitoring the behavioral reaction to a lower reward (downshift) after exposure to a larger or better incentive. It supports the idea that an acceptable but less preferred reward will be rejected in a situation that is associated with a better and more desirable reward. The intensity of FNR depends, among other things, on the strength of the expectation of the large reward. We assumed that overtraining would enhance reward expectancy such that a reward downshift would lead to a stronger cSNC effect than that observed under regular training conditions. This would support the hypothesis that behavior (licking for sucrose) was guided by reward expectancies—an action. But overtraining often leads to habitual behavior that depends on eliciting stimuli, rather than reward expectancies. A failure to show the cSNC effect after overtraining would be consistent with the hypothesis that behavior had become automatic—a habit. Our experiment was designed to test whether overtraining in the cSNC task would result in behavior becoming either an action or a habit. In the experiment, 47 rats were exposed to different concentrations of sucrose, 32%, 16%, or 4%, and 2 training periods, overtraining for 30 sessions and regular training for 10 sessions. Animals exposed to 32% and 16% sucrose were randomly assigned to two groups depending on the amount of training they received before the downshift, either 30 (overtraining) or 10 sessions (regular training). These animals were given access to 4% sucrose after their designated training period. An unshifted control group received only access to 4% sucrose throughout training. The data obtained after 10 vs. 30 sessions of training were compared to the unshifted controls. The results showed that overtraining enhanced the cSNC effect relative to regular training, suggesting that licking was an action guided by the expectation of the current reward, rather than a habit. These results suggest that FNR induced by reward downshifts overcomes the development of a habit even after prolonged training.

Humans produce complex and learned behaviors like speech, playing musical instruments, and sports through exceptional motor abilities. These learned actions need specific motor planning and preparation. Researchers use songbirds in part because they produce a stereotyped motor sequence whenever they engage in singing behavior. Further, Zebra Finches learn their song through vocal production learning, similar to human speech acquisition; they mimic their adult male tutor's song and reproduce a similar version in adulthood. This motor learning process leads to the generation and execution of a highly skilled and stereotyped motor program production. Before the song, Zebra finches sing a sequence of introductory notes that are short-duration, non-stereotyped sounds. Previous work has speculated that these introductory notes are a form of motor preparation, but an experimental test of this hypothesis has not been conducted. This study casually examines the role of introductory notes as a motor preparation phase to help transition to executing the main song motor sequence. To distinguish motor preparation from song execution, we reasoned that presenting an external stimulus would delay preparation but not execution. We used air pressure recording to identify introductory notes and triggered white-noise playback during the introductory note performance in six birds and found that the external stimulus led to a delay, which can lead to interruption of the typical song motor pattern (e.g., abnormal pauses). Whereas the same stimulus presented during the song either caused an abnormal early termination of the motor program or did not affect the song (continuation), but it did not delay the execution of the song's motor gestures. Our findings suggest that introductory notes are flexible and modifiable by external stimuli, which is consistent with the hypothesis that they function as a preparatory motor gesture for the upcoming stereotyped song.
Understanding motor planning can provide insight into neurological, behavioral, speech, and motor disorders that are characterized by deficits in neuromuscular preparation.

Recent discussions surrounding law enforcement have highlighted varying opinions on the ability of police officers to respond effectively to mental health-related incidents. Given that 20% of police calls involve mental health or substance abuse issues, it is crucial that the general population is confident about the role of police as mental health interventionalists. The current study assessed DFW residents’ (N = 64) perceptions of the police’s ability to intervene in mental health crises utilizing in-person and online 7-point Likert scale surveys (where 1 = disagree strongly and 7 = agree strongly). Survey results showed that confidence in police’s ability to handle mental health crises increases with age, p = .04. Older participants expressed greater trust, while younger respondents were more skeptical. No significant differences were found in gender, race, ethnicity, or socioeconomic status, highlighting a generational divide in public trust. These results suggest that there is potential for improving younger individuals’ attitudes towards police intervention.

Rats use many cues when navigating to food, shelter, or a mate. The use of visual cues (e.g., landmarks) has been reported in many species. In rats, these cues include those around their start position, the experimenter, as well as landmarks located in (intramaze) or around (extramaze) the search space. In the current experiment, rats were placed into a start box with a transparent door and released onto an open field. We examined whether rats were able to discriminate between two different intramaze landmarks (wooden figurines; A and B) from the start box. Landmark A trials were reinforced with a Froot Loop© hidden in a cup behind the landmark (A+), but no Froot Loop was present on Landmark B (B-) trials or on C- trials with no landmark. Latency to the goal cup was measured and revealed no differences between the three trial types. The procedure was modified to include two response locations (to the left and right of the landmark). A+ and B+ trial types were reinforced at different cups. There was no difference in accuracy for searching the correct cup first. The use of non-visual cues, the discriminability of the landmarks, and the response cost of search will be discussed.

Bird song has been extensively investigated as a model for understanding the physiological basis for animal vocalization.. Juvenile songbirds acquire their songs and perfect them as they transition into adulthood, just as we acquire our native language by exposure and imitation of adult tutors. Scientific investigation of bird song requires the collection of hundreds of hours of audio data containing songs, calls, and cage noise. These data must be sorted into categories of interest for specific research questions, with singing behavior being the dominant behavior of interest. Data categorization is a tedious and time-consuming process, and while current software hastens this process, substantial human effort is still required. This project investigates whether or not machine learning algorithms can be used to more efficiently categorize audio data collected in songbird research. Specifically, we developed a convolutional neural network (CNN) in PyTorch to classify whether or not 0.5 second sections of audio contain bird song. Using a supervised learning paradigm, we trained the CNN using labeled spectrograms (visual representations of audio frequencies across time) acquired from recordings of the zebra finch (Taeniopygia guttata). After training the CNN, we implemented it into an algorithm that identifies song within audio recordings. We then compared the CNN based software to a pre-existing, custom-written LabVIEW template-matching algorithm to determine the relative speed and accuracy of the software. Recordings were taken in both noisy and quiet recording environments to test the strengths and limitations of the two approaches. Our data indicate that the CNN based algorithm achieves comparable levels of accuracy to the pre-existing algorithm and accomplishes the categorization using a fraction of the time required by the template matching program. . These results suggest that machine learning algorithms can effectively be used to automate and rapidly categorize stereotyped vocal patterns. Further development of this software may facilitate rapid analysies of data and be extended to categorization of a broader range of vocal patterns, including human speech.

Hormonal contraceptives can have many negative side effects that deter women from using them. One example that many women are unaware of is alcohol craving. Preliminary studies in our lab have shown that women on hormonal contraceptives have greater alcohol cravings than women who are naturally cycling. Given that this data is mostly survey-based, we aim to add a research manipulation in the current study. We are testing this through a Qualtrics survey, distributed via Amazon’s Mechanical Turk (Mturk), that is designed to prime alcohol cravings. We will ask women to rate their alcohol cravings before and after they watch a video containing alcohol. We expect that when primed with an alcohol video, women’s cravings towards alcohol will increase to a level higher than before they watched the video. Further, we expect to find that women on hormonal contraceptives will have a higher increase in cravings than women who are regularly cycling. If we do find that women on hormonal contraceptives have a stronger reaction to an alcohol cue, women would benefit from being well informed about this effect. For instance, armed with the knowledge that hormones influence craving and behavior, women may be more mindful about their drinking habits. In addition, we eventually hope that this knowledge will influence those who are developing future contraceptives to take these side effects into account.

Existential isolation can be described as the experience of feeling alone in one’s experience of the world; that no one shares your experience or comes close to understanding it (Pinel et al., 2017). Research on existential isolation remains novel, however current findings among those chronically existentially isolated has found significant associations with a host of negative affective outcomes, including increased loneliness (Pinel et al., 2017), death thought accessibility (Helm et al., 2019), depression and anxiety (Constantino et al., 2019), and reduced self-esteem and self-worth (Helm et al., 2018). Finally, there is novel and consistent evidence that existential isolation is related to insecure attachment, specifically avoidant attachment (Helm et al., 2020).

Recent literature has found that adverse early life experiences are one of the factors that can proactively influence adult well-being, resulting in consequences such as anxiety and depressive disorders, and suicidal ideation (Hays-Grudo and Morris, 2020). Additional work has also shown that childhood abuse was uniquely associated with greater loneliness among young adults (Landry et al., 2022) but the impact of early life experiences on loneliness can be impacted by a multitude of factors including, but not limited to, age, gender, socioeconomic factors, and epigenetic factors (Southwick et al., 2014). While loneliness is inherently a part of the feeling of existentially isolated, existential isolation itself is distinct in theoretically meaningful ways that this study aims to investigate through the lenses of adverse childhood experiences and childhood uncertainty. This present study aims to qualitatively examine the relationship between adverse childhood experiences and existential isolation among adult individuals. Our findings across two studies established a positive association between individuals who have experienced adverse childhood experiences and existential isolation.

Recent research has begun to explore the basic misperceptions that underly political divides. For instance, people tend to believe that their political opponents accept objective moral wrongs (e.g., homicide, watching child pornography). These misperceptions then motivate avoidance and dehumanization of political opponents. However, the socio-cognitive processes preceding the formation of these misperceptions are less understood. Across two studies, we examined existential isolation towards political opponents, or the belief that people with a different political orientation than you do not understand your perspective and worldview, as one such social determinant. Study 1 surveyed 194 undergraduate students, and Study 2 surveyed 250 adults via Amazon Mechanical Turk. Results provide consistent support to suggest that individuals feel more existentially isolated from political opponents (e.g., politically liberal individuals report feeling more existentially isolated from politically conservative others). The more existential isolation people felt towards liberal or conservative others, the more they believed that these individuals endorsed objective moral wrongs, the less willingness they were to engage in political discussions with these individuals, and the more they dehumanized them. These findings emphasize the important role of existential isolation in the formation and persistence of political divides, and highlight the need for interventions that target feelings of existential isolation towards one’s political opponents.

The Ineffective Anxiety-Buffering Mechanisms on Well-Being and Psychological Disorders in Traumatized Individuals

Psychological well-being is shaped by an individual’s ability to buffer existential anxiety through self-esteem, cultural worldviews, and close relationships. However, prior research suggests that trauma weakens these mechanisms, increasing vulnerability to distress. Studies indicate that individuals with high trauma exposure struggle to reinforce cultural values in response to mortality salience, leaving them susceptible to psychological disorders. This study examines whether disrupted anxiety-buffering mechanisms contribute to increased fear of death and lower well-being. Participants, which are college students, (N=100) will complete measures assessing childhood trauma (ACE), fear of death (CL-FODS), and well-being (SWLS, PANAS). It is hypothesized that high-trauma individuals will report greater death anxiety and lower well-being compared to their low-trauma counterparts. This research aims to refine models of trauma’s psychological impact and inform interventions designed to restore effective anxiety-buffering mechanisms in survivors.
