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.

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
The present study tested the respective mediating effects of sensation seeking and initial level of response (LR) to negative, sedative alcohol effects on the relation between the density of familial history of alcoholism and adolescent alcohol use. Additionally, the present study tested the direct effect of LR to negative, sedative alcohol effects on adolescent drinking over and above the effects of sensation seeking; and also tested the moderating effect of sensation seeking on the relation between level of response negative, sedative alcohol effects and adolescent drinking. Specifically, OLS regression models first estimated the effects of sensation seeking, LR to negative, sedative alcohol effects, and their interaction on alcohol outcomes, over and above the influence of covariates. Indirect effects were then tested using the PRODCLIN method through RMediation. Analyses failed to support sensation seeking as a mediator in the relation between familial history of alcoholism and adolescent drinking, and as a moderator of the relation between LR and adolescent drinking. However, analyses did support a robust direct effect of LR to negative, sedative alcohol effects on adolescent alcohol involvement. A significant mediating effect of initial LR to negative, sedative alcohol effects on the relation between familial alcoholism and adolescent drinking was found, however failed to maintain significance in post-hoc analyses attenuating the downward bias of the measure of initial LR. Initial LR to negative, sedative alcohol effects continued to predict adolescent drinking after attenuating measure bias. These findings strengthen research on initial LR to negative, sedative alcohol effects as a risk for greater alcohol involvement in adolescence, and underscore the complexity of studying the familial transmission of alcoholism in adolescent populations

Description
Using data from a randomized, experimental trial of a brief family-based preventive intervention for parentally-bereaved families, this study evaluated whether participation in the Family Bereavement Program (FBP) when the offspring were in childhood/adolescence (ages 8 to 16) improved competencies when the offspring were emerging/young adults (ages 23 to 32). Participants were 244 emerging/young adults; data used were from assessments at pretest, posttest, 6 years post-intervention, and 15 years post-intervention. In addition to testing the direct effects of the program, developmental cascade effects models were used to test the relations between program-induced improvements in positive parenting and decreased negative life events at posttest and subsequent effects on domains of competence and behavior problems in adolescence/emerging adulthood (ages 14 to 22) and four developmental competencies of emerging/young adulthood: academic, peer, romantic, and work competence. Results supported a cascading effects model of program effects on competence outcomes. In the full sample, there were significant mediation effects of the intervention to decreased negative life events at posttest to increased grade-point average (GPA) at the 6-year follow-up to higher academic and work competence at the 15-year follow-up. For females only, two additional significant mediational pathways of the FBP occurred. The FBP led to an increase in peer competence 6 years post-intervention, which was associated with an increase in work competence 15 years post-intervention. Also, the FBP led to a decrease in externalizing problems in adolescence/emerging adulthood, but externalizing problems were positively associated with work competence. For males, additional mediation effects of the FBP on work competence occurred. The FBP decreased negative life events. However, higher negative life events were associated with lower externalizing problems in adolescence/emerging adulthood, and externalizing problems were positively associated with work competence. For males only, a significant three-pathway mediation effect of the intervention occurred on increased positive parenting at posttest to increased romantic attachment at the 6-year follow-up to higher romantic competence at the 15-year follow-up. Peer competence showed continuity over development. Mediational analyses highlighted the role of program-induced improvements in parenting, reductions in exposure to negative life events, and earlier developmental competencies on competence outcomes in emerging/young adulthood. Implications for promoting resilience in parentally-bereaved, at-risk youth are discussed.

Description
Alcohol use among romantic partners is known to be related to a variety of detrimental outcomes, such as decreased relationship satisfaction and increases in conflict. However, discrepant drinking among partners may be a stronger predictor of relationship outcomes over and above the amount of alcohol use. Currently, little is known about potential differences in the within- and between-person effects and discrepancy’s effect on mood, particularly among community samples. The current study investigated the effects of both individual and partner alcohol use, as well as discrepant drinking, on mood and relationship functioning. Data were obtained from 280 heterosexual romantic couples using a measurement burst daily dairy design over the course of one year. Actor Partner Interdependence Model and Dyadic Score Model analyses were used to investigate the effect of alcohol use and discrepant drinking on mood and relationship functioning, both at the within- and between- person levels. Specifically, analyses investigated the effects of no drinking versus moderate drinking, no drinking versus binge drinking, and moderate drinking versus binge drinking. Results revealed that while binge drinking may be related to positive outcomes proximally, the cumulative effects at the between-person level are detrimental. Moreover, discrepant drinking appears most detrimental when women outdrink their partners. These findings have important implications for refining and improving upon couples-based interventions aimed at alcohol-use problems among non-clinical couples.

Description
Alcohol use disorder (AUD) causes immense global burden and has a significant impact on economic and societal functioning. Efficacious treatments for AUDs have been well-established within the literature, however the most commonly accessed treatments for AUD are alcohol-related services, such as self-help groups, outpatient clinics, and detoxification centers. Though studies suggest these services are effective at treating AUDs, there are numerous differences between individuals who receive alcohol-related services and individuals who do not, causing selection bias. Furthermore, current studies of alcohol-related services frequently define recovery outcomes as abstinence, which reduces variability in viable recovery outcomes, such as reduction of drinking behaviors. In addition, reduction in drinking and alcohol-related problems should theoretically have an impact on broader aspects of functioning, such as familial functioning. Improved familial context may reduce risk to family members, who are otherwise at heightened risk for emotional and behavioral problems when living with a family member with AUD. The current study investigated the effect of alcohol-related services on binary and continuous drinking outcomes after eliminating selection bias using multiple propensity score approaches, to identify the best methodology for a high-risk community sample of individuals with AUD. Propensity scores were created using logistic regression approaches and boosted regression trees. Matching, weighting, and subclassification were used, and matching was performed both using greedy and global approaches. Results suggested subclassification was the most successful method for real world alcohol-related services samples with moderate sample size. Moreover, findings demonstrated that boosted regression approaches were less successful than logistic regression approaches at minimizing the effects of selection bias on known confounding variables that are highly related to group selection. In addition, after removing the effects of selection bias, there were no significant difference between participants who received alcohol-related services and the comparison control group on drinking or family functioning, though both groups reduced drinking from pre- to post-alcohol-related services receipt. Findings suggest careful selection of quasi-experimental methods is warranted in real-world samples, to ensure optimal removal of selection bias. Moreover, future studies should continue to clarify the profile of individual that benefits from alcohol-related services to inform intervention efforts.

Description
Despite the established co-prevalence of substance use (SU) and disordered eating (DE), few longitudinal studies have sought to examine their shared development. Findings have been inconsistent within the extant literature. This may be attributable in part to several methodological aspects, including overlooking distinct psychopharmacological properties of common substances of abuse, examining only between-person relations, and failing to account for shared risk factors. The current study sought to address these gaps by applying latent curve models with structured residuals (LCM-SR) to a preexisting, national sample of adolescent girls followed into adulthood, Add Health. In Aim 1, between-person effects examined the simultaneous development of alcohol, tobacco, and marijuana use and DE behaviors in substance-specific models. In Aim 2, bivariate latent curve models were expanded to account for within-person effects (LCM-SR) in order to examine the potentially bidirectional, prospective relationship between use of a specific substance and DE. Lastly, models accounted for shared developmental risk factors. Findings of the current study demonstrate preliminary evidence of substance-specific effects with DE emerging in adolescence. Across model-building steps, DE engagement in early adolescence was significantly associated with growth in tobacco use and marginally associated with marijuana use. Appetitive side-effects of both substances may link use with DE behaviors and enhance instrumental use for weight control. Significant associations did not emerge between alcohol and DE, and results of the conditional model indicate this co-occurrence is best explained by third variable mechanisms. Implications for prevention are discussed.

Description
Negative Urgency and Positive Urgency are important subfacets of a propensity to rash action. There is currently limited research on parental antecedents of Negative Urgency and Positive Urgency. The current study investigated whether parent personality and parenting behaviors predict adolescent Negative Urgency and Positive Urgency. Data were taken from a community sample with parent personality, positive parenting behaviors, and child Negative Urgency and Positive Urgency measured at separate timepoints. Structural equation models were used to examine whether parent personality predicted adolescent Negative Urgency and Positive Urgency and whether positive parenting mediated this relationship. There was no evidence for a relationship between parent personality and children’s Negative Urgency and Positive Urgency. In addition, there was no relationship between parenting behaviors and child Negative and Positive Urgency in cross-reporter models, but child-reported parenting predicted later adolescent-reported Negative and Positive Urgency. Greater positive parenting, as perceived by children, was related to less Negative and Positive Urgency when they were adolescents. More research is needed to understand whether the current results are due to reporter bias or whether child-perceived parenting behaviors influence the development of adolescent Negative and Positive Urgency.

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
Prior research has established a relation between parenting behaviors and symptoms of child psychopathology, and this association may be influenced by both genetic and environmental factors. Gene-environment correlation, or the influence of a child’s genes on the environment they receive, represents one possible mechanism through which genes and environment combine to influence child outcomes. This study examined evocative gene-environment correlation in the relation between parenting and symptoms of child psychopathology in a sample of 676 twins (51.5% female, 58.5% Caucasian, 23.7% Hispanic/Latinx, primarily middle class, MAge=8.43, SD=.62) recruited from Arizona birth records. Using univariate ACE twin biometric models, genetic influences were found to moderately contribute to internalizing symptoms (A=.47, C=.25, E=.28), while externalizing (A=.86, E=.14) and ADHD (A=.84, E=.16) symptoms were found to be highly heritable. The genetic influences for positive (C=.54, E=.46) and negative (C=.44, E=.56) parenting were smaller and found to be nonsignificant. The correlations between parenting and types of psychopathology were examined and bivariate Cholesky decompositions were conducted for statistically significant correlations. Negative parenting was moderately positively correlated with externalizing and ADHD symptoms; the relation between externalizing symptoms and negative parenting was found to be due to shared genetics, whereas the relation between negative parenting and ADHD symptoms was due to the shared environment. The mixed results regarding the role of gene environment correlation in relations between parenting and child psychopathology indicate that further research on the mechanisms of this relation is needed.
