Description
Anorexia Nervosa is an increasing problem in today's day and age. With the overbearing messages of what the media portrays to be beautiful, some people are responding by engaging in unhealthy eating habits. By taking embodied cognition into consideration, there may be a method to help treat people with Anorexia Nervosa that has not been attempted yet. According to embodied cognition, the body influences the way a person thinks (Glenberg, 2010). If people with Anorexia Nervosa are thinking in unhealthy ways in terms of their body, providing relief from these unhealthy forms of thinking may come in the form of using a surrogate body: a virtual avatar in a video game. Through explanation and integration of the Embodied Social Presence Theory, the use of a virtual avatar as a surrogate body for victims of Anorexia Nervosa becomes a probable and viable method of ushering treatment. The avatars are not an explicit treatment of Anorexia Nervosa, but rather a way to allow actual treatment and therapy to be more successful.

Description
Anti-gay bias is a prevalent aspect of traditional male gender norms that has negatively impacted the lesbian, gay, bisexual, and transgender (LGBT) community, both in terms of mental and physical health. This study examined how anti-gay bias varies as a function of gender, education level, and field of study. We hypothesized that men will have more bias than women, that seniors in college will be less biased than freshmen in college, and that male students in sub disciplines of engineering that have relatively more women (e.g., biomedical engineering), will be less biased than those in more homogeneous, male-dominated fields (e.g., mechanical engineering). Past research has identified the implications of gender and education level in anti-gay bias; the current study looked to further such research and to investigate possible implications of the impact of settings that have a gender imbalance. A total of 303 undergraduate students from Arizona State University completed an online survey that measured attitudes toward lesbian, gay, bisexual, and transgender individuals and communities. Neither education level nor academic field of study were found to have influenced degree of bias. Limitations and implications of the study are discussed.

Description
There are two common cognitive distortions present in risky decision-making behavior. The gambler's fallacy is the notion that a random game of chance is potentially biased by previous outcomes, and the near-miss effect is the overestimation of the probability of winning immediately after barely missing a win. This study replicated a portion of the methods of Clark et al. (2014) in an attempt to support the presence of these two fallacies in online simulated risky decision-making tasks. One hundred individuals were recruited and asked to perform one of two classic gambling tasks, either predict the outcome of a dichromatic roulette wheel or spin a simplified, two-reel slot machine. An analysis of color predictions as a function of run length revealed a classic gambler's fallacy effect in the roulette wheel task. A heightened motivation to continue playing after a win, but not a near or full miss, was seen in the slot machine task. How pleased an individual was with the results of the previous round directly affected his or her interest in continuing to play in both experiments. These findings indicate that the gambler's fallacy is present in online decision-making simulations involving risk, but that the near-miss effect is not.

Description
Perceptions of the self differ between cultures, generally between those cultures in the West and East. Some of the ways that these individuals from these cultures may differ are in their self-construal, their collectivist and individualist tendencies, and how they perceive control in their lives. The current study proposes that some of these differences are influenced by different concepts individuals hold regarding the "soul", or inner self. These concepts may be promoted by the different religious beliefs prominent in different regions. The Soul Perception Index, being developed through this study, measures belief in multiple souls, a universal soul, a single soul, or no soul. It was predicted that a belief in a single soul will correlate with an individual view of the self (individualism, independent self-construal, internal locus of control), and a universal or multi-soul belief will correlate with an interdependent view of the self (collectivism, interdependent self-construal, and external locus of control). We found that these variables did not significantly differ in their relationships with soul belief. However, Indian Hindu participants and Chinese participants seemed to score highly on all self-view variables and all soul perception types indicating that individuals from these cultures may be more predisposed to hold opposing beliefs simultaneously while US Christians are not.

Description
Sibling interactions are natural contexts for learning about the appropriate expression of emotions. The emotionally charged nature of sibling interactions creates a convenient context to explore emotional reactivity and regulation. The purpose of this study was to examine the relations among parent-reported sibling relationship quality, observed sibling prosocial and antisocial behaviors displayed when playing a competitive marble game, and children's emotions coded from videotape. The sample consisted of 58 twin children who are currently participating in the longitudinal Arizona Twin Project. Parents completed the Sibling Relationship Questionnaire online at 5 and 8 years. Additionally, a competitive marble game interaction between the siblings took place in the home at 8 years and was videotaped for objective coding of prosocial, antisocial, and control behavior. Facial expressions were also coded from videotape using Emotient FACET software across the marble game interaction. Three mean composites of emotion were created, including positive and negative emotional facial expressions. Results showed that parent reported warmth did not predict the occurrence of positive emotions during the sibling interaction. However, siblings with high conflict showed less fear during the interaction. Parent reports of warmth predicted the extent to which siblings differed on emotion expression, however conflict did not. Parent ratings of conflict and warmth did not predict the extent to which the sibling dyad was emotionally intense. Findings regarding genetic and environmental effects were in line with previous reports of genetic influence on prosocial behavior and negative emotion, and expressions of joy being influenced by the environment. This study investigated noteworthy aspects of the sibling relationship that appear to promote children's adaptive development.

Description
A recent controversy has surrounded service dogs in public environments. Use of service dogs may trigger discrimination against individuals with non-visible disabilities. Major goals of this thesis study are to examine if significant differences exist in personality perceptions and attitude towards service dog owners with visible disabilities versus those with non-visible disabilities, and whether these perceptions and attitude predict how they would be treated in a public setting. The study employed a mixed 2 x2 factorial experiment design. The first independent variable was visibility of the disability, with the two levels being visible vs non-visible, and this factor was non-repeated in nature. The second independent variable was the target of evaluation, with the owner and the dog being the two levels, and this was a repeated measure. Specifically, this study assessed personality perceptions using the Big Five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience) and operationalized attitude in terms of the positivity of personality perceptions. Additionally, this study examined whether an owner of a service dog with a non-visible disability would be treated differently from their counterpart who has a visible disability. In the study, participants were given a scenario and picture where they encounter an individual who either had a visible or non-visible disability with a service dog at a restaurant. Then, participants rated the owner and the dog individually on the Big Five personality traits, and indicated whether and how likely they would seat the individual and their service dog at the restaurant. When considering the visibility of a disability alone, an individual with a non-visible disability was perceived as less conscientious. When considering how the owner and the dog were perceived regardless of visibility of disability, owners were rated significantly lower than their dog on agreeableness and extraversion, but significantly higher on openness to experience. There was also a significant difference in treatment of the dog owners based on the visibility of their disability, service dog owners with non-visible disabilities have a higher likelihood of experiencing unlawful treatment. Furthermore, personality perceptions and attitude were significantly correlated with treatment for both individuals with non-visible and visible disabilities. Together, findings of this study inform the design of future research. Future research on this topic may help inform policy makers the challenges and unfair treatment facing individuals who have non-visible disabilities.

Description
Previous research pertaining to dog memory and cognition has been confined mainly to samples of colony dogs and therefore can be hard to generalize to a larger population of pet dogs and varying breeds. The present study focused entirely on pet dogs of many different breeds, rather than colony or laboratory animals for the purposes of accessibility, affordability, and novelty. Methods: We presented the dogs with a memory task in the form of a game in which the dogs chose to search for food at one of two locations at varying delay intervals, with a maximum time limit of one hour per dog. We expected our data to show a significant decrease in memory capacity and an increase in error rates among older dogs as compared to younger dogs; these results would allow us to conclude that it is likely many dogs, much like humans, experience various cognitive deficits as a function of increasing age. Results: Using one-factor ANOVA and linear and curvilinear regression analyses, we examined the relationship between the independent variable, age (individual dog ages as well as three generalized age categories), and three dependent variables. The dependent variables were: (a) percentage of correct choices at a 60 second delay interval, (b) maximum delay interval attempted (MDIA), and (c) the maximum delay interval that was completed above chance level (50%) (MDAC). We found significant results to support our hypotheses that aged dogs show spatial memory and cognitive deficits in comparison with young and middle-aged dogs, and that age can be considered a marginally significant predictor of spatial memory capacity.

Description
The purposes of the study are to: 1) investigate how students' motivation towards reading is related to their reading comprehension skills, and 2) assess the impact of using an Intelligent Tutoring System to improve comprehension. Interactive Strategy Training for Active Reading and Thinking-3 (iSTART-3) is a game-based tutoring system designed to improve students' reading comprehension skills. The current study was conducted in South Africa with 8th and 9th graders between the ages of 14 and 18. These students are multilingual and they learn English as a First Additional Language (English-FAL). Firstly, we predict that students who are highly motivated to read will have high comprehension scores than those who are slightly or not at all motivated to read. Secondly, we predict that the use of iSTART-3 will improve students' reading comprehension, regardless of their level of reading motivation, with better results for those who are more motivated to read. Counter to our predictions, the results did not reveal a relation between reading motivation and reading comprehension. Furthermore, an effect of iSTART-3 on reading comprehension was not found. These results were likely influenced by the small sample size and the length of the intervention.

Description
The aim of this study was to determine whether IUD administration, with and without the presence of Levo, and with and without the presence of the ovaries, impacts cognition in a rat model. Rats received either Sham or Ovariectomy (Ovx) surgery (removal of the ovaries), plus either no IUD, a Blank IUD (without Levo), or a Levo-releasing IUD (Levo IUD), enabling us to evaluate the effects of Ovx and the effects of IUD administration on cognition. Two weeks after surgery, all treatment groups were tested on the water radial arm maze, Morris water maze, and visible platform task to evaluate cognition. At sacrifice, upon investigation of the uteri, it was determined that some of the IUDs were no longer present in animals from these groups: Sham\u2014Blank IUD, Ovx\u2014Blank IUD, and Sham\u2014Levo IUD. Results from the remaining three groups showed that compared to Sham animals with no IUDs, Ovx animals with no IUDs had marginally impaired working memory performance, and that Ovx animals with Levo IUDs as compared to Ovx animals with no IUDs had marginally enhanced memory performance, not specific to a particular memory type. Results also showed that Ovx animals with Levo IUDs had qualitatively more cells in their vaginal smears and increased uterine horn weight compared to Ovx animals with no IUDs, suggesting local stimulation of the Levo IUDs to the uterine horns. Overall, these results provide alternative evidence to the hypothesis that the Levo IUD administers Levo in solely a localized manner, and suggests that the possibility for the Levo IUD to affect reproductive cyclicity in ovary-intact animals is not rejected. The potential for the Levo IUD to exert effects on cognition suggests that either the hormone does in fact systemically circulate, or that the Levo IUD administration affects cognition by altering an as yet undetermined hormonal or other feedback between the uterus and the brain.

Description
Teacher assessments are often used alongside parent assessments to identify behavioral problems and patterns in school-aged children. These assessments can aid in the diagnosis of disruptive behavior disorders and are used to screen children for targeted delinquency prevention programs. Although researchers have heavily studied the relationship between parent and teacher assessments, not as much research has analyzed teacher assessments alone, specifically semiannual teacher assessments. Teacher assessments are typically conducted during the fall semester, normally a couple months into the school year, or during the spring semester, normally a couple months after the winter break period. Using data from the Pittsburgh Youth Study (PYS), we aimed to determine the temporal stability and predictive utility of semiannual teacher assessments of children's behavioral problems from 2nd grade to 5th grade. Results showed that mean assessment scores increased from the fall to the spring semester across all 4 grades. We also found that teacher assessments of behavioral problems in grade school were significantly correlated with future serious violence. Although our statistical model did not identify a specific time period or semester when these assessments were most predictive, we observed a pattern where the spring semesters were more predictive for the younger grades, and the fall semesters were more predictive for the older grades. Future research could aim to understand why this pattern exists and what its implications are.
