Description
The interconnection between family contexts and sleeping patterns play a crucial role in childhood development, with disturbances in either being indicative of future health outcomes in adulthood. It is unclear whether sibling relationships and sleep would have a similar effect as there are not many studies that have examined these links by using subjective sleep and sibling relationship assessments. Given this gap in the literature, the present studied aimed to 1) examine potential bidirectional relations between sibling relationships (warmth, conflict) and sleep variables (duration, efficiency, and sleep midpoint variability) across ages 8 and 10, and 2) test whether a novel sibling interaction task with measures of sharing and competition conducted at age 8 predicts sleep variables both cross sectionally and two years later at age 10. Data are from the Arizona Twin Project which includes a racially and socioeconomically diverse representation of children in Arizona. Twins wore an actigraph watch at both age 8 and age 10 to capture sleep duration and efficiency. Primary caregivers also reported sibling relationships via a questionnaire during both waves. Twins completed a marble pulling task to measure negotiation and cooperation behaviors at age 8 only. We tested cross-lagged prospective associations between sleep and sibling contexts. My study identified a longitudinal, positive association with sibling warmth at age 8 and sleep duration at age 10 and another concurrent, positive association with sibling conflict at age 8 and sleep midpoint variability at age 8. A negative association was identified between sibling warmth and sleep efficiency at age 10. Stability over time was also identified in both sleep variables and sibling relationships. Future studies can further investigate the different ways siblings may influence sleep behaviors, or vice versa, by taking into consideration the quality of the relationship, age, gender, and overall family dynamics. Due to the complexity of sibling relationships, the relations between sleep and siblings may vary among different individuals and families. These additional factors may need to be considered when evaluating the effects of sibling relationships and sleep on child development and well-being.

Description
Chronic pain is common among children and can lead to future physical disability and health problems. The Biopsychosocial model of child pain suggests that biological, psychological, and social factors predict pain risk, but most research has focused on biological and psychological factors impacting child pain, and less on social factors. One social factor is family stress, including parent mental and physical health problems, and parenting and marital stress. The impact of stress, however, may vary depending on the presence of positive family resources, including marital empathy, parental warmth, and interpersonal support. Thus, the current longitudinal study examined links between family stress and increases in child pain during middle childhood and tested whether positive resources acted as a buffer to protect the development of child pain and if low social status acted as an extra stressor to make pain worse. Participants were part of the Arizona Twin Project, an ongoing longitudinal project of twins. At twin age 9, primary caregivers (PCs) reported on different stress, social status, and positive resources measures, and PCs and twins reported on twin bodily pain. At twin age 11, PCs and twins again reported on twin chronic bodily pain. Neither greater family stress nor parent physical health problems predicted increases in child pain over two years, controlling for twin pain at age 9. In tests of moderation, a single significant interaction emerged in a direction opposite of prediction: the relation between family stress and child pain was moderated by social status, such that average and high levels of social status exacerbated the relation between family stress, and child pain at age 11. Although the interaction needs to be replicated, findings suggest that high social status may act as a risk factor for poor child physical health and pain when family stress is high. Future research should further explore whether and how family stress and social status, as well as peer stress and resources, alone and in combination predict health as children age into adolescence.

Description
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.

Description
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.

Description
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.

Description
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.

Description
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.

Description
Introduction: Edibles, THC-infused food products, are a popular type of cannabis. However, there is limited research on how acute effects of edibles differ from more traditional cannabis types, such as smoked flower (e.g., dried bud). The current study examined the subjective response of cannabis between smoked flower and edibles using a two-week long ecological momentary assessment (EMA). Sex differences were also examined.Method: Individuals (n=101) using both edibles and flower at least once weekly completed a cannabis report within 30 minutes (T1) of first cannabis use each day as well as two follow-up reports sent 1.5 (T2) and 3 hours (T3) after initial use. Participants additionally completed assessments throughout the day for fourteen consecutive days to examine daily affect. Multi-level models examined whether overall high, low-arousal negative effects, high-arousal negative effects, and general positive effects differed by edibles and flower. Given time differences in effects between cannabis types, subjective effects were examined at T1, T2, and T3, as well as for the peak effects across the three-hour time window. Covariates included demographics, variant- and invariant- cannabis use characteristics, and daily affect.
Results: At T1, edibles produced lesser positive effects (b=-0.60, S.E.=0.16, p=0.001) and overall high (b=-2.00, S.E.=0.27, p<0.001) relative to flower. At T2, edibles produced greater positive effects (b=0.52, S.E.=0.21, p=0.01) relative to flower. At T3, edibles produced greater low-arousal negative effects (b=0.63, S.E.=0.23, p=0.01) relative to flower. Edibles produced greater peak low-arousal effects relative to flower (b=0.59, S.E.=0.21, p=0.01), With respect to sex differences, there was an interaction between sex and cannabis type at T1 for positive effects (b=-0.99, S.E.=0.31, p=0.001), such that males reported greater positive effects for flower. Males additionally reported lesser low-arousal effects at T1 (b=-0.60, S.E.=0.30, p=0.05) and greater overall high at T3 relative to females (b=1.24, S.E.=0.56, p=0.03).
Discussion: Smoked flower produced greater effects immediately and edibles produced greater delayed effects. Edibles appear to have greater peak levels of low-arousal effects (e.g., sluggish, drowsy, slow) relative to smoked flower. Males may be more sensitive to the rewarding effects of cannabis, particularly when smoking flower.

Description
A dynamical approach is used to avoid isolating systems and instead view systems as interacting together. The current study applied a dynamical approach to heart rate variability and personality. There were two main research questions that this study sought to answer with a dynamical analysis of heart rate variability and personality: “Can we listen to a heartbeat and draw connections to behavior and personality?” and “Is dynamical analysis more effective than traditional analysis at finding correlations between heart rate variability and personality?” To answer these questions a dynamical analysis of heart rate variability was conducted (detrended fluctuation analysis; DFA) along with traditional analysis (standard deviations of NN intervals, SDNN, and root mean squared of successive deviations, RMSSD) and then correlations between heart rate variability measures and personality traits from the Big Five Inventory, Positive and Negative Affect schedule, and State-Trait Anxiety Inventory were examined. Data for this study came from the Rapid Automatic & Adaptive Model for Performance Prediction (RAAMP2) Dataset that was part of The Multimodal Objective Sensing to Assess Individuals with Context (MOSAIC) project. There were no statistically significant correlations between heart rate variability and personality. However, there were notable correlations between extraversion and SDNN and RMSSD and between positive affect and SDNN and RMSSD. We found that SDNN and RMSSD were more closely correlated to each other compared to DFA to either measure. This suggests that DFA can provide information that SDNN and RMSSD do not. Future research can explore dynamic analysis of heart rate variability and other nested systems.

Description
This study sought to determine if perceived neighborhood danger impacted children's sleep. The current study asks: how does perceived neighborhood danger impact children’s sleep both quantity and quality (duration and efficiency), could children’s physical activity mediate these associations, and how do genetic and environmental factors play into these relationships? Questionnaires, biological measurements, and actigraphy watch data were collected from 709 8-year-old Arizonan twins and their parents in order to calculate neighborhood safety, sedentary physical activity, moderate to vigorous physical activity, sleep duration, and sleep efficiency as well as covariates. It was concluded that perceived neighborhood danger does not directly impact children’s sleep duration and efficiency, children’s physical activity does not mediate the relation of perceived neighborhood danger and children’s sleep, but rather, perceived neighborhood danger indirectly impacts children’s sleep duration and efficiency through moderate to vigorous activity, and finally, that both sedentary and moderate to vigorous activity are heavily influenced by genetics.
