Description
The benefits of earning a college degree are clear, yet nearly half of first-time, full-time college students do not complete their degree within 6 years. Completing college is no simple task and students must regularly make decisions not to prefer the smaller, immediate rewards over the larger, future reward of graduation (i.e. temporal discounting). Recent research shows initial support that temporal discounting can be reduced by heightening future self-continuity. This thesis study pilot tested an ecological, scalable approach to increase future-self continuity by heightening three components, similarity, vividness and positivity, within the framework of social media. Participants completed measures of these components before and after simulating the creation of a social media profile for themselves 10 years after college graduation. A significant increase in perceived similarity to the future self from Time 1 to Time 2 was detected in a within-subjects test. The findings in this study are encouraging and may inform the development of interventions aimed at increasing future self-continuity in college students.

Description
The purpose of this study was to examine executive cognitive functioning (ECF) and drinking induced disinhibition as potential mechanisms through which a family history (FH) of alcohol problems contributes to off-spring alcohol-related problems. We also examined the hypotheses that indirect effects of family history would be moderated by age of drinking onset, hypothesizing that indirect effects of family history through ECF and drinking induced disinhibition would be stronger among those with an earlier age of drinking onset. The sample included 177 college aged heavy drinking participants (66.2% men; 33.8% women; 78.8% Caucasian; 10.1 % African American; 6.9% Hispanic; 4.2% Multi-racial; 4.8% other) participating in a randomized controlled trial of naltrexone (vs. placebo) plus brief motivational counseling for drinking reduction. Measures of family history, self-control, working memory, and drinking induced disinhibition collected prior to randomization to treatment condition (intake assessment), were used to explore the hypothesized mechanisms of FH effects. Although FH was not related to either working memory or self-control, self-control predicted both drinking induced disinhibition and alcohol-related problems, with a marginal indirect effect of self-control on problems through drinking induced disinhibition. Age of drinking onset did not moderate relations between FH and measures of ECF (working memory and self-control). The findings suggest that self-control is a major factor contributing to the development of alcohol-related problems. Thus self-control may be an important target of intervention regardless of age of drinking onset or family history status.

Description
Abstract: Behavioral evidence suggests that joint coordinated movement attunes one's own motor system to the actions of another. This attunement is called a joint body schema (JBS). According to the JBS hypothesis, the attunement arises from heightened mirror neuron sensitivity to the actions of the other person. This study uses EEG mu suppression, an index of mirror neuron system activity, to provide neurophysiological evidence for the JBS hypothesis. After a joint action task in which the experimenter used her left hand, the participant's EEG revealed greater mu suppression (compared to before the task) in her right cerebral hemisphere when watching a left hand movement. This enhanced mu suppression was found regardless of whether the participant was moving or watching the experimenter move. These results are suggestive of super mirror neurons, that is, mirror neurons which are strengthened in sensitivity to another after a joint action task and do not distinguish between whether the individual or the individual's partner is moving.

Description
Virtual reality (VR) educational games are growing in demand, partly because of evidence found of the benefit of using embodied gestures in educational VR games. Little research has investigated how presence, which is the subjective experience of existing in a virtual world, impacts player learning gains when playing an embodied STEM VR games. The current study investigates how presence impacts learning gains in four conditions. This study evaluated 122 participants’ subjective experiences of presence via an experimenter-designed Presence Scale after playing an educational STEM VR game. ANOVAs were conducted to evaluate differences in learning gains by condition and to also ascertain how presence was affected by cognitive load. Results revealed that presence did not impact learning gains, although high embodiment and high immersion significantly predicted presence. These findings contribute to understanding the effects of embodiment on VR educational games, and how to design for VR user-ability.

Description
Catholic confession is one of the most practiced and well-known religious acts in the world. Although Catholic confession has proven to be an important component in the lives of millions of people, little research has been conducted exploring trust engagement within Catholic confession or the variables that affect one’s willingness to confess. The purpose of this study was to examine Catholic confession and find whether variables such as perception of the sexual abuse within the Catholic Church, ability, benevolence, and integrity of the priest, Catholic Church, and pope, propensity to trust, trust, and intrinsic religiosity have a significant relation with one’s willingness to confess. This study was conducted through a series of anonymous questionnaires, including two measures that were created for the purpose of this study—the Sex Abuse Perception Measure and Willingness to Confess Measure. Linear regressions and correlations were used to analyze relation between variables. Results revealed that the perception one has of the sexual abuse within the Catholic Church is significantly related to the perceived ability, benevolence, and integrity for a priest, Catholic Church, and the pope. Additionally, ability and benevolence had a moderate positive relation with trust in a priest and the pope and benevolence and integrity had a moderate positive relation with trust in the Catholic Church. Surprisingly, there were no significant relations between propensity to trust and trust in the priest, Catholic Church, or the pope. Similarly, there were no significant relations between trust in the priest, Catholic Church, or the pope and one’s willingness to confess. Intrinsic religiosity did have a positive relation with willingness to confess. This study highlights that individual and organizational religious figures possibly have differing origins of trust (ability, benevolence, and integrity). This difference may be related to one’s perception of the sexual abuse that occurred within the Catholic Church.

Description
Alcohol consumption in first-year college students is both prevalent and problematic. Although several interventions have been shown to decrease alcohol consumption in college students, effect sizes tend to be small. Previous programs have focused on reducing risk factors; however, some research has shown potential in bolstering promotive and protective factors. The main objective of the current study was to further our understanding of the use of promotive and protective factors in alcohol prevention and intervention for first-year college students. A sample of 290 college psychology majors were assigned to either a treatment group or the standard curriculum of a first-semester course on achieving academic success. The intervention included activities aimed to increase academic engagement and community engagement, promote healthy minds and bodies, and promote positive social lives, including engagement in alcohol-free social activities. Students completed baseline measures at the beginning of the fall semester of their first year in college and a follow-up near the end of the semester. Analyses examined proximal targets (use of university resources, perceptions of peer alcohol use, academic engagement, school connectedness) and behavioral targets (personal alcohol use and GPA) of the intervention. Analyses demonstrated changes in proximal targets, but no significant effects of the intervention on behavioral targets. Students in the treatment condition utilized more school resources, had lower perceptions of peer alcohol use, and were marginally higher in school connectedness than those in the control condition. This suggests that the use of promotive and protective factors in alcohol prevention and intervention may contribute to attitudes and behaviors that are associated with better academic performance and less engagement in risk behavior. However, no significant changes were found for personal alcohol use or GPA. Future studies involving longer follow-ups and adding a skills-based component are needed to fully evaluate the potential of this approach.

Description
The first step in providing adequate prevention of children’s behavior problems is identifying possible predictors. There is an established relation between parenting style and behaviors and children’s future outcomes, including risk of externalizing behavior problems, but the mechanisms that may explain this relation are unclear. The current study investigated whether child executive functioning plays a mediating role between parenting style and externalizing behavior problems. I hypothesized that parenting style, specifically harsh authoritarian parenting, would predict a decrease in child executive performance, then leading to increased child behavior problems. Additionally, sex differences within this model were examined. Parenting styles and child externalizing behavior problems were measured through mother’s self-report within a sample of 322 low-income, Mexican-American mother child dyads in the Phoenix metropolitan area. A mediation model was performed, including relevant covariates, to test for significance of the mediated pathway. The results of the current study indicated that authoritarian parenting style significantly predicted greater externalizing behavior problems in the sample, but only for girls. Interestingly, it was also found that the addition of biological siblings predicted less behavior problems, again only for girls. These results promote understanding of the influences on behavior problems in children that can escalate to delinquency and criminal behavior. This information is critical for the development and improvement of strategic interventions.

Description
Women are twice as likely as men to develop Major Depressive Disorder (MDD), and current MDD therapies are only effective for about a third of patients. Hormonal transitions, specifically those involving estradiol (E2), have been found to contribute to this increased vulnerability in women. This study aimed to investigate potential mechanisms underlying the sex differences seen in MDD vulnerability, specifically the role of E2. The brain region-specific changes induced by chronic stress differ for female rats than for male rats. Therefore, we aimed to determine the effects of sex and chronic stress on E2 expression in four brain regions: the hippocampus, medial prefrontal cortex, amygdala, and cerebellum. Sprague-Dawley rats (n = 48, 24 males, 24 females; n=12/Tx group) were subjected to daily wire mesh restraint stress (6 h/21 days), and were euthanized and dissected the day following the end of chronic restraint stress (day 22). Ultra high-pressure liquid chromatography-mass spectroscopy was used to directly measure E2 in the brain regions. Quantitative real-time PCR was used to indirectly assess E2 expression via mRNA for aromatase (ARO-L) and estrogen receptors (ERβ, ERɑ, and GPR30), as well as expression of inflammatory cytokines (IL-1β and TNF-ɑ). Our findings suggest that chronic stress may lead to changes in local estradiol expression in the brain that are both sex-dependent and brain region-specific, while the data are preliminary given the small sample size. We found that expression of ARO-L mRNA, a measure of local E2 production, tended to increase in the HIPP, but decrease in the mPFC following chronic stress, and in the mPFC this pattern was only observed in males. Local estradiol production in the brain seems to act as a potential compensatory mechanism in the hippocampus, but as a protective mechanism in the mPFC, which is highly sensitive to chronic stress.

Description
Previous research demonstrated the overall efficacy of an embodied language intervention (EMBRACE) that taught pre-school children how to simulate (imagine) language in a heard narrative. However, EMBRACE was not effective for every child. To try to explain this variable response to the intervention, the video recordings made during the four-day intervention sessions were assessed and emotion was coded. Each session was emotion-coded for child emotions and for child-researcher emotions. The child specific emotions were 1) engagement in the task, this included level of participation in the activity, 2) motivation/attention to persist and complete the task, as well as stay focused, and 3) positive affect throughout the session. The child-researcher specific emotions were 1) engagement with each other, this involved how the child interacted with the researcher and under what context, and 2) researcher’s positive affect, this incorporated how enthusiastic and encouraging the researcher was throughout the session. It was hypothesized that effectiveness of the intervention would be directly correlated with the degree that the child displayed positive emotions during the intervention. Thus, the analysis of these emotions should highlight differences between the control and EMBRACE group and help to explain variability in effectiveness of the intervention. The results did indicate that children in the EMBRACE group generally had a significantly higher positive affect compared to the control group, but these results did not influence the ability for the child to effectively recall or moderate the EEG variables in the post-test. The results also showed that children who interacted with the researcher more tended to be in the EMBRACE group, whereas children who did not interact with the researcher more frequently were in the control group, showing that the EMBRACE intervention ended up being a more collaborative task.

Description
Pediatric chronic pain is surprisingly common and impactful, prospectively predicting poorer mental and physical health outcomes. Internalizing symptoms represents one such outcome. It is the most common cluster of symptoms in children, it is related to poorer child functioning, and it has been linked to future functioning/psychopathology. The psychosocial mechanisms through which child pain may impact internalizing have yet to be fully elaborated, but withdrawal from social engagement with peers has been proposed as one possible mechanism. Additionally, sibling relationships may play a role in enhancing or diminishing a child’s social engagement while they are in pain. The current study aimed to examine whether child social engagement at age 8 mediates the relation between child chronic pain at age 8 and internalizing symptoms at age 9. Further, the study tested whether sibling warmth and sibling conflict act as moderators between child chronic pain and child social engagement. The physical and emotional health, quality of sibling relations, and extracurricular social engagement of 491 twin children from 247 families were assessed at age 8 and age 9 via surveys completed by the children’s primary caregivers. Findings showed that child pain at age 8 did not predict lower levels of social engagement, and social engagement did not predict child internalizing at age 9. Sibling warmth, but not conflict, significantly moderated the pain—social engagement relation. Together, these findings indicate that the relation between chronic pain and internalizing functions differently in children than in adults through a variety of cognitive, environmental, and social factors. More longitudinal research in this area will help establish changes in the relation between pain and internalizing from childhood into adulthood.
