Description
In this study, potential differences in the manifestation and rates of eating disorders and symptoms (body dissatisfaction, weight and shape concerns, food restriction, and compensatory behaviors) in college women across sexual orientations were examined. The sociocultural model of eating disorders was also examined for these women across sexual orientations. The participants were organized into three different sexual orientation groups for analysis: heterosexual (group 1), bisexual, pansexual, and polysexual (group 2), and lesbian, gay, queer, transsexual, asexual, and other (group 3). Using cross-sectional data, it was revealed that there were significant group differences when comparing the three sexual orientation groups on loss of control over eating, but no significant group differences on body dissatisfaction, thin ideal internalization, and weight-related eating pathology, and total eating disorder symptoms scores. The sociocultural model was not predictive of eating disorder symptoms among non-heterosexual groups. Longitudinal analyses revealed that the sociocultural model of eating disorders prospectively predicts eating disorder symptoms among heterosexual women, but not non-heterosexual women. Both cross-sectional and longitudinal analyses indicate that non-heterosexual women may be protected from societal pressure to subscribe to the thin ideal and its subsequent internalization. However, the comparison group of heterosexual women in our study may not have been completely representative of undergraduate women in terms of total eating disorder symptoms or eating pathology. Additionally, regardless of sexual orientation, our sample reported more total eating disorder symptoms and emotional eating than previous studies. These findings have both clinical and research implications. Future research is needed to determine what risk factors and treatment target variables are relevant for non-heterosexual women.

Description
I propose that norms regulate behaviors that negatively impact an individual's survival and reproduction. But because monitoring and enforcing of norms can be costly, individuals should be selective about which norms they police and under what circumstances they should do so. Two studies tested this idea by experimentally activating fitness-relevant motives and having participants answer questions about the policing of norms. The first study examined a norm prescribing respect for status and another proscribing sexual coercion. Results from Study 1 failed to support the hypotheses; activating a status-seeking motive did not have the predicted effects on policing of the respect-status norm nor did activating a mating motive have the predicted effects on policing of the respect-status norm or anti-coercion norm. Study 2 examined two new norms, one prescribing that people stay home when sick and the other proscribing people from having sex with another person's partners. Study 2 also manipulated whether self or others were the target of the policing. Study 2 failed to provide support; a disease avoidance motive failed to have effects on policing of the stay home when sick norm. Individuals in a relationship under a mating motive wanted less policing of others for violation of the mate poaching norm than those in a baseline condition, opposite of the predicted effects.

Description
There is preclinical evidence that the detrimental cognitive effects of hormone loss can be ameliorated by estrogen therapy (Bimonte, Acosta, & Talboom, 2010), however, one of the primary concerns with current hormone therapies is that they are nonselective, leading to increased risk of breast and endometrial cancers as well as heart disease. Thus, in order to achieve a successful and clinically relevant long-term hormone therapy option, it is optimal to find an estrogen therapy regimen that is selective to its target tissue. Recently, phytoestrogens have been found to exert selective, beneficial effects on cognition and brain. For example, genistein and diadzein produce neuroprotective effects in cognitive brain regions (Zhao, Chen, & Diaz Brinton, 2002). The purpose of this study was threefold: 1) to examine the cognitive impact of phytoestrogens in young ovariectomized rats, 2) to replicate the dose effects found in the Luine study (Luine et al., 2006), while controlling for manufacturer differences, and 3) to assess if the rodent diet used in our laboratory has an estrogenic-like cognitive impact.The current findings suggest that, at least for object memory, diets containing varying amounts of phytoestrogens can alter cognition, with diets containing high amounts of phytoestrogens showing potential benefits to this type of memory.

Description
This study aims to examine how crossover relations from one parent relate to the other parent's view of familial relationships. The study examines mood state and psychological distress as variables that relate to each other and familial relationships. Home visits were scheduled with families of normally developing three-year olds. During these home visits, naturalistic observation and surveys were done. Researchers then conducted regression analyses to examine the relation between mood state, psychological distress, and familial relationships. The data showed that there were significant relations between one parents' psychological distress and how the other parent viewed the marital relationship, indicating a crossover relation between those two variables.

Description
The purpose of this thesis was to identity various sports psychology techniques utilized during the injury recovery process of an NCAA athlete. Using a qualitative approach, past research was analyzed to uncover different features of an athletic injury as well as possible intervention methods. Findings suggested that effective intervention techniques structured around the Self Determination Theory (SDT), more specifically the concept of strengthening the satisfaction of an individual's three basic psychological needs: competence, autonomy and relatedness. Following the collection of past research, a series of interviews were conducted with four practicing sports psychologists. Interview questions focused on determining possible distinctions between acute, chronic and career-ending injuries as well as intervention techniques employed. Utilizing data collected from past research as well as the interviews, an applied brochure was developed for the potential benefit of an injured athlete. The established techniques, if utilized properly, should strengthen the satisfaction of an athlete's psychological needs according to the SDT, which may ultimately foster a positive and successful return-to-sport experience.

Description
Visual aides, such as PowerPoint slides, hand-outs, and lecture notes on whiteboards, are often used in classrooms to convey important content to learners, especially in high school and college. When using these visual learning aides, it is important to consider which qualities of these presentations can affect learning— positively or negatively—and how those qualities interact with individual student characteristics. In the present study, we examine the overlap between audio and text and how the effects of overlap potentially interact with reading comprehension abilities. The examination of these potential influences on learning in this study is inspired by Cognitive Load Theory, the Dual-Channel Assumption, and prior research.

Description
Prospective memory is defined as remembering to carry out specified actions in the future. Research has suggested that prospective memory retrieval is reliant on multiple cognitive processes to function, and the ways in which these different processes are used is dependent on a variety of variables relating to the prospective memory task at hand. The current study focuses on the strength of the association between the prospective
memory cue and the prospective memory intention. Based on literature suggesting that aspects of prospective memory are reliant on executive control functioning, the current study examined the possibility that executive control depletion would affect prospective memory ability on subsequent tasks. Results showed that depletion of executive control resources, measured objectively, did not impair prospective memory in either a low or
high cue-association condition. However, participants‟ subjective assessment of their own fatigue correlated significantly with their subsequent prospective memory performance, regardless of association condition. The results of the study indicate that depletion studies that fail to account for both objective and subjective measures suffer from an unclear interpretation of effects, and that recognition of perceived expectancies
of cognitive resource limitation can assist in improving prospective memory ability.

Description
Prospective memory is defined as the process of remembering to do something at a particular point in the future after first forming a conscious intention. There are three types of prospective memory intentions; event-based, time-based and activity-based intentions. Research has suggested that activity-based is one of the dominant prospective memory failures that people self-report yet there is little research on this area of prospective memory. The current study focuses on how activity-based PM is influenced by the association between the match of internal context and intended action. According to previous research, similar context between intention formation and retrieval has been shown to facilitate prospective memory, which increases the execution of intentions. Based on literature, we hypothesized that there would be higher intention completion when the internal context matches the intended action to be completed in the future. Results showed that internal context affected activity-based intention completion significantly. However the interaction between internal context and the intended action did not significantly affect intention completion. Although we did not get the hypothesized interaction, the means do cross over showing the interaction pattern is there. We decided to treat this as a pilot study and replicate it with a well-powered experiment consisting of 560 valid participants.

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.
