Survivors of military sexual assault (MSA), which has been shown to be positively linked with negative posttraumatic cognitions (NPTCs), may be at an increased risk of engaging in sexual risk behaviors. However, the relation between sexual risk-taking and NPTCs among MSA survivors is understudied. In the present study, it was hypothesized that (1) there would be a significant positive association between sexual risk-taking and NPTCs among MSA survivors, and (2) sex would significantly moderate this association, such that the relation between NPTCs and sexual risk-taking would be stronger among male MSA survivors compared to female survivors. Secondary data came from the Military Social Science Laboratory (MiSSiLe) at Arizona State University (ASU). Participants (N = 400) completed surveys in Qualtrics, Inc. assessing military history, MSA exposure, sexual risk-taking, and NPTCs. Pearson’s correlation and simple linear regression with moderation were used to test the above hypotheses, covarying for age, marital status, military branch, and history of PTSD treatment. Results showed a significant positive association between sexual risk-taking and NPTCs among MSA survivors (p < .001); however, the interaction between sex and NPTCs only approached significance, such that the association was slightly stronger for male MSA survivors compared to female survivors (p = .055). These results suggest that the interplay between sexual risk-taking and NPTCs could be an important target for improving healthcare for MSA survivors. Furthermore, future research may consider utilizing study samples that more accurately reflect the distribution of service members across all military branches and the sex distribution of service members and veterans. Doing so would improve generalizability and better inform treatment.

The body tilt illusion relates to one’s exaggerated perception of body tilt angle in comparison to reality. People tend to overestimate this illusion and feel that they are tilted at 45º when they are tilted less than 45º in reality. This illusion increases with lack of sensory cues and decreases when sensory cues are added. In the present study, distortion in the perception of body tilt was examined as a function of center of mass. There are gender differences in regards to where one’s center of mass lies on their body, with females having a lower center of mass on average compared to males (Elert, 2005). We used a human-sized 3D gyroscope to test participants’ experience of the body tilt illusion. The findings support that perception of body tilt is multisensory and that visual information as well as the tilting plane affects the magnitude of the illusion. This is consistent with the illusion being functional for helping people keep their balance. Yet, we did not find significant differences in the size of the illusion due to differences in center of mass. The pattern of findings supports that the body tilt illusion is relatively universal, and likely functional, but does not vary much due to individual body shape differences like center of mass.

Power— defined as material or social resources one brings into a relationship—can influence the experiences of each partner and has implications for relationship satisfaction. Queer individuals have distinct sexual and gender identities that may influence power dynamics within their relationships, yet Queer relationships have rarely been investigated. We used cross-sectional data to examine how sexual orientation and gender interact to predict experiences of power in Queer relationships, and how power experience affects relationship satisfaction. Participants (N = 196) were recruited online via Prolific. Analyses suggested that lesbians experience the most egalitarian power dynamics, followed by heterosexuals, with bisexual/pansexuals and gay men experiencing the least egalitarian power dynamics. Relationship satisfaction followed a similar trend across groups, consistent with previous work. However, no interaction was found between participant gender and sexual orientation in predicting power dynamics. Exploratory analyses revealed a possible significant association of satisfaction with power in one’s relationship and relationship satisfaction, beyond effects of overall power dynamics. We benefited from a diverse sample; however, our analyses were underpowered. Future studies should continue to examine power dynamics in Queer relationships, and the role of satisfaction with couple power differentials and gender roles in mediating these associations.

In this study, the role of attention in facial expression processing is investigated, especially as it relates to fearful facial expressions compared to happy facial expressions. Facial fear processing plays a critical role in human social interactions and survival, and this has previously been studied mainly in animal models. This study, however, was accomplished with the presentation of images of actors with happy and fearful facial expressions in three spatial frequency formats, as it is hypothesized that images at different spatial frequencies may be processed via different pathways. These images were presented to human participants in two experiments. In Experiment I, facial expression was task-relevant as participants were asked to discriminate between “happy” and “fear” expressions with reaction time (measured in seconds) and accuracy recorded. In Experiment II, facial expression was task-irrelevant, as participants were asked simply to discriminate between photographs of males and females, again with reaction time and accuracy recorded. Overall, the results comparing happy and fearful facial expressions in Experiment I were not significant. The results comparing happy and fearful facial expressions in Experiment II exhibited similar insignificant results except for accuracy in certain spatial frequencies, which were found to be significant. These results suggest that fearful facial expressions are processed more accurately than happy facial expressions when attention is focused on other variables in the image rather than when attention is focused on the facial expressions themselves.

Memory as whole is impacted by changes associated with aging and menopause. Different memory types are often tested preclinically utilizing rats in different task paradigms. Most studies have focused on understanding social recognition or working memory, however these memory types have yet to be studied together. This thesis focuses on the process of creating and testing a new social recognition task that incorporates a working memory load. We tested different types of previously used social recognition paradigms with an increasing load and through qualitative and quantitative observations the task was modified until a final task was developed for a social working memory study. Young female rats were tested in this task in progressive, meaning a chronologically increasing load and nonprogressive, meaning non-chronological increase in load cognitions. It was found that young female rats had the ability to distinguish between the familiar and novel conspecifics before memory load exceeded four familiar and one novel conspecifics. Once validated through future studies, this task may be utilized to understand the impact of different types of menopause on social working memory.

It is well documented that menopause and the related decline in circulatory steroid hormones estrogen and progesterone are associated with memory alterations. Rodent models of surgical menopause can be used to study these effects, including ovariectomy (Ovx), or the surgical removal of the ovaries. This thesis aimed to characterize the effects of surgical menopause on spatial working and reference memory in rats and examine profiles of uterine gene expression alterations that may serve as indications of mechanisms underlying this association. Eighteen female rats were randomly assigned to one of two surgical treatment groups, either Ovx (the surgical menopause group) or sham (the control group). All subjects underwent testing on the water version of the radial arm maze (WRAM) which allows for the assessment of reference memory errors and two types of working memory errors. After behavioral testing, rat uterine tissues were dissected and RNA sequenced. The results showed that Ovx impaired spatial reference memory performance during a maze learning phase, with Ovx rats making reference memory failures earlier in the day, even before working memory load increased, as compared to control rats. There were no surgical menopause effects on spatial working memory, which may be due to the low working memory load and the young age of the rats. Post-hoc analyses showed that reference memory performance was correlated with nerve growth factor (NGF) and acetylcholinesterase (AChE) gene expression in uterine tissues. These findings add to the literature on the impact of estrogen and female cyclicity on memory and cognition. The results suggest that Ovx impairment of the ability to learn long-term spatial memory information relates to uterine gene expression underlying cellular functioning and that NGF and AChE genes are involved in pathways that give way to underlying cellular functioning that impacts cognition. Future studies should continue to evaluate the effects of menopause on memory function and the effectiveness of hormone therapy.

Approximately 20% of youth experience mental health problems (Vasileva et al., 2021), and dimensions of early childhood temperament, specifically negative affectivity and effortful control, predict later mental health (Rothbart, 2007). Examining temperament using person-centered methods, particularly in stressful contexts, may improve our understanding of vulnerability to adolescent emotional problems. The current study examined whether specific patterns, or types, of infant temperament longitudinally predicted adolescent anxiety and depression symptoms and whether family relationship stress moderated this association. We hypothesized that infants with a Negative Dysregulated temperament would experience higher anxiety and depression symptoms in later childhood compared to those with a Typical Expressive temperament, and that family relationship stress would exacerbate this link. In an ongoing-longitudinal study of families with twins (N=563, 51% female, 29.8% Hispanic/Latinx, 58.4% White; Lemery-Chalfant et al., 2019), primary caregivers (PCs) reported on infant temperament at 12 months (IBQ; Gartstein & Rothbart, 2003, α=.74-.90). In a prior study (Murillo et al., 2023), latent profile analysis yielded three infant temperament types: Negative Dysregulated, Positive Well-Regulated, and Typical Expressive. PCs reported on partner strain (PSS; Schuster, Kessler, & Asseltine, 1990, α=.87) and family conflict (FCS; Porter & O’Leary, 1980, α=.80) at age 8 and a composite of these two measures represented Family Relationship Stress (r = .689). Confirmatory factor analysis was used to form Depression and Anxiety outcome composites based on PC (4 reports), secondary caregiver (2 reports), teacher (2 reports), and self-report (3 reports) measures of depression and anxiety symptoms collected from ages 8-11 (HBQ, Armstrong & Goldstein, 2003; BPI, Measelle et al., 1998, all α’s > .80). We randomly selected one twin from each pair and conducted regression analyses, and then used the second twin for an internal replication. Family relationship stress had a significant main effect on both anxiety and depressive symptoms. The Negative Dysregulated temperament type did not predict anxiety and depression at ages 8-11, however, it interacted with family relationship stress to predict anxiety and depression in 1 of 2 samples. When family relationship stress was low, the Negative Dysregulated type was significantly associated with higher anxiety and depression outcomes compared to the Typical Expressive type, and high family relationship stress was significantly associated with lower depression outcomes. Elucidating these longitudinal relations is important for informing early intervention and reducing the burden of adolescent psychopathology.

Before the introduction of mobile/online forms of gambling, “brick and mortar” gambling was the typical form of gambling. Now, the use of mobile phones allows for greater accessibility and convenience to gambling. This modern method of gambling has attracted newer younger audiences such as college students which poses an increasing concern about problem gambling among younger individuals. Since alcohol use problems tend to co-occur with problem gambling, it is important to consider alcohol use as a predictor of problem gambling. Other factors that could potentially influence the relation between alcohol use problems and problem gambling are financial stress (as an indicator of socioeconomic status) and sensation seeking; however, the potential interactive effects of these variables with problem alcohol use in predicting problems remain unclear. The main goals of the current study were to examine the unique and interactive influences of alcohol use problems, sensation seeking, and financial stress in relation to problem gambling. The sample for the current study was taken from the Psychology participant pool enrolled at Arizona State University and met the minimum age requirement of 18 (N = 793, 64.1% Male). All analyses were conducted using R Studio (R Core Team, 2023). I ran a a series of logistic regression models for my covariates only, main effects (alcohol use problems and financial stress or alcohol use and sensation seeking) models while controlling for covariates, and interaction models (alcohol use problems multiplied by financial stress and alcohol use problems multiplied by sensation seeking). Results showed that alcohol use problems and sensation seeking were not significant predictors of problem gambling. However, financial stress (SES), sex (male), and age proved to be significant predictors of problem gambling. There were no interactions found between alcohol use problems and socioeconomic status or sensation seeking on problem gambling outcomes. Although some results from the current study are inconsistent with existing literature, the significant findings provide insight into potential future directions and treatment programs for problem gambling among college students. Further studies are needed to develop a more comprehensive understanding of the complex interactions between alcohol use problems, socioeconomic status, and sensation seeking in relation to problem gambling.

Active U.S. service members and veterans engage in heightened and hazardous alcohol consumption, which has negative implications when it comes to fulfilling their military duties. It is common for service members and veterans to suffer from both posttraumatic stress disorder (PTSD) and hazardous alcohol use concurrently, and it is unclear how other challenges could strengthen or weaken this relation. The current study examined the extent to which posttraumatic cognitions (PTCs)–conceptualized as thinking negatively about the world, self, and self-blame–moderated the relation between PTSD and alcohol use in service members with a history of military sexual assault (MSA). An additional exploratory analysis was conducted to see if there was a possible mediating role PTCs play in the relation between PTSD and alcohol use. The current study utilized data from a parent study that administered self-report surveys to 400 U.S. service members and veterans (50%) with a history of MSA. At the bivariate level, PTSD and PTCs were significantly associated with higher alcohol use. PTCs did not moderate the association between PTSD severity and alcohol use severity. An exploratory analysis of PTCs as a mediator of the relation between PTSD and alcohol use found a significant indirect effect of PTSD severity on alcohol use severity through higher PTCs. PTCs could be a target for cognitive-behavioral therapy treatments among those who are experiencing heavy alcohol use.

For centuries, religion has been a part of people's lives, impacting their well-being. Well-being includes both positive and negative emotions that make people feel satisfied. Religion can affect how people handle their physical health, social behavior, support, and stress. Interestingly, more people have been abandoning religion since 1990, even though it has positive effects on well-being. In this study, I sought to understand the extent to which leaving religion is associated with all aspects of well-being, including spiritual well-being. I asked 606 Arizona State University undergraduates to rate their well-being from two different time periods in their life. Participants were first asked if they were currently religious or nonreligious;135 said they had left/changed religions. If participants indicated that they did not leave/change religions, they were asked about their well-being before and after starting at ASU. I examined perceived change in well-being to understand how religion can influence many aspects of an individual’s life. Leaving or changing religion was positively associated with well-being. Those who reported leaving religion reported better environmental, emotional, social, educational, occupational, and spiritual well-being. In the control group (ASU), educational and spiritual well-being had a significant increase, which is interesting. The results showed that changing/leaving religion had a positive association on well-being.
