Description
Asthma is one of the most common chronic diseases affecting children, and investigators have identified a number of risk factors that worsen asthma symptoms. Most prior studies have concluded that there is an association between one risk factor, poor sleep quality, and asthma; however, whether sleep quality predicts future asthma symptoms, asthma symptoms predict future sleep quality, or the relation is reciprocal is still unclear. The methodology of studies examining the asthma-sleep association has consisted of actigraphy and parent report to determine children's sleep duration and sleep efficiency, and lung function assessments with a spirometer on the participants to determine children's overall lung function. The purpose of the proposed study is to determine the strength of the cross-sectional and longitudinal associations between indicators of sleep quality and asthma. The proposed study plans to use a combination of actigraphy, sleep diaries, and lung function assessments using a spirometer to determine sleep quality and lung function, respectively. Future directions include determining the directionality of the association between sleep quality and asthma as well as strength of association.

Description
As a biology major, many of my classes have included studying the fundamentals of genetics or investigating the way genetics influence heritability of certain diseases. When I began taking upper-division psychology courses, the genetic factors of psychological disorders became an important part of the material. I was exposed to a new idea: that genes were equally important in studying somatic diseases as they were to psychological disorders. As important as genetics are to psychology, they are not part of the required courses for the major; I found many of my peers in psychology courses did not have a grasp on genetic fundamentals in the same way biology majors did. This was a disconnect that I also found in my own life outside the classroom. Growing up, my mother consistently reminded me to limit my carbs and watch my sugars. Diabetes was very prevalent in my family and I was also at risk. I was repeatedly reminded of my own genes and the risk I faced in having this biological disorder. However, my friend whose father was an alcoholic did not warn her in the same way. While she did know of her father's history, she was not warned of the potential for her to become an alcoholic. While my behavior was altered due to my mother's warning and my own knowledge of the genetic risk of diabetes, I wondered if other people at genetic risk of psychological disorders also altered their behavior. Through my thesis, I hope to answer if students have the same perceived genetic knowledge of psychological diseases as they do for biological ones. In my experience, it is not as well known that psychological disorders have genetic factors. For example, alcohol is commonly used by college students. Alcohol use disorder is present in 16.2% of college aged students and "40-60% of the variance of risk explained by genetic influences." (DSM V, 2013) Compare this to diabetes that has "several common genetic variants that account for about 10% of the total genetic effects," but is much more openly discussed even though it is less genetically linked. (McVay, 2015)This stems from the stigma/taboo surrounding many psychological disorders. If students do know that psychological disorder are genetically influenced, I expect their knowledge to be skewed or inaccurate. As part of a survey, I hope to see how strong they believe the genetic risk of certain diseases are as well as where they gained this knowledge. I hypothesize that only students with a background in psychology will be able to correctly assign the genetic risk of the four presented diseases. Completing this thesis will require in-depth study of the genetic factors, an understanding of the way each disease is perceived and understood by the general population, and a statistical analysis of the survey responses. If the survey data turns out as I expect where students do not have a strong grasp of diseases that could potentially influence their own health, I hope to find a way to educate students on biological and psychological diseases, their genetic risk, and how to speak openly about them.

Description
Self-regulation in the form of coping with emotions is something that most people have effectively adapted to by adulthood. This is an organically learned process that begins in early childhood through play, parenting, education, and peer interactions. This study examines whether six children aged 4-5 (M age= 4.72, SD= 0.372, 50% female, 100% Caucasian) are able to understand basic emotions and how to cope with them through one of two protocols. The conditions were either directive instruction or embodied cognition, and children were evaluated with a pre and post-test measure. Findings did not indicate any significant effect of the conditions on memorizing coping mechanisms, nor did it indicate that there was a significant improvement in emotion understanding following the sessions. These findings were limited by the sample size and participant interest.

Description
This paper explores the idea of xenophilia and the circumstances under which it may occur. Xenophilia is the preference for an outgroup member over an ingroup member. This preference does not have to be amicable, and in fact can be exploitative under certain circumstances. Previous research indicates that xenophobia is much more common, but a few researchers have found support for the existence of xenophilia. To experimentally test the circumstances under which xenophilia might occur, I conducted a survey-based experiment on Amazon’s Mechanical Turk. This consisted of directed visualizations that manipulated participant goal (self-protection vs. mate acquisition) and the resources offered by both a fictitious outgroup and the hometown ingroup, followed by measures of ingroup/outgroup preference. I hypothesized that when the resource offered by the group addressed the participants’ goal, they would prefer the group with the “matched” resource—even if it was the outgroup providing that resource. My hypothesis was not supported, as the univariate analysis of variance for preference for the outgroup was not significant, F (2, 423) = .723, p = .486. This may have occurred because the goal manipulations were not strong enough to counteract the strong natural preference for ingroup members.

Description
A handheld metal cricket noisemaker known as a "clicker" is often used in dog training to teach dogs new behaviors; however, evidence for the superior efficacy of clickers as opposed to providing solely primary reinforcement or other secondary reinforcers in the acquisition of novel behavior in dogs is almost entirely anecdotal. We sought to determine under what circumstances a clicker may result in acquisition of a novel behavior to a higher level when compared to other potential reinforcement methods. In Experiment 1, three groups of 30 dogs each were trained to emit a novel sit and stay behavior with either the delivery of food alone, a verbal marker with food, or a clicker and food. The group that received only a primary reinforcer reached a significantly higher criterion of training than the group trained with a verbal secondary reinforcer. Performance of the group experiencing a clicker secondary reinforcer was intermediate between the other two groups, but not significantly different from either. In Experiment 2, three different groups of 25 dogs each were shaped to emit a nose targeting behavior and then perform that behavior at increasing distances from the experimenter using the same three methods of positive reinforcement used in Experiment 1. No statistically significant differences between the groups were found. Overall, the findings suggest that both clickers and other forms of positive reinforcement can be used successfully in training a dog to perform a novel behavior.

Description
This study examined the cross-sectional and longitudinal associations among diurnal cortisol rhythms and sleeping patterns in adolescents. 79 participants completed the study over three days during the spring semester of their senior year in high school, and 76 of these subjects participated again over three days during the fall semester of their freshman year in college. They completed daily saliva samples and diary entries, while wearing an actigraph to obtain objective measurements of sleep duration and efficiency. Cross-sectionally, longer sleep duration was associated with a lower cortisol awakening response, a smaller area under the cortisol curve, and a steeper cortisol slope. Longitudinally, there was no significant relationship between sleep duration and these cortisol parameters. Moreover, sleep efficiency was not associated with cortisol parameters cross-sectionally nor longitudinally. Results suggest associations between concurrent sleep duration and cortisol patterns, and may have significant impact on understanding adolescents' physiological response to stress.

Description
Perhaps by some ingrained sense of human preparedness, phobias are an outlier in the world of conditioning. Again and again, they are highlighted as the only thing which avoidance makes worse, rather than alleviates. My own fear of insects had reached its most severe level just as I began learning about phobias, and avoidance, in my undergraduate psychology courses. There, I learned that avoidance of the phobic stimulus \u2014 in my case, insects \u2014 seemed to be a fundamental element of maintaining a phobia, and I was more than guilty of it. Following this realization, I endeavored into what I would later come to call Stimulus Confrontation: A self-designed therapeutic course of action to overcome my fear. This thesis, then, is the record of this project. It weaves together my scholarly research on phobias with my own personal narrative concerning the employment of Stimulus Confrontation, beginning with the etymology and proposed etiologies of phobias, followed by an overview of contemporary treatment options available and a recounting of Stimulus Confrontation as applied to my own phobia. Told from her own perspective, English writer and journalist Jenny Diski's book, What I Don't Know About Animals, tells of her own arachnophobia, and includes an honest account of the fear and anxiety it caused for her, as well as her own journey to overcome it. Like my own, Diski's phobia \u2014 arachnophobia \u2014 had come to affect her everyday life. Prior to seeking treatment for her fear at the age of 58, Diski too had learned to avoid the thing which she so feared. Inspired by What I Don't Know About Animals, the personal anecdotes I have included throughout this thesis serve to elaborate upon my personal experience with my own insectophobia, and the cessation of avoidance that led to substantial progress in overcoming my fears. Throughout this thesis, I refer to this cessation of avoidance as Stimulus Confrontation, with the intention that following the same process I did may benefit others in overcoming their own specific phobias.

Description
Humans use emotions to communicate social cues to our peers on a daily basis. Are we able to identify context from facial expressions and match them to specific scenarios? This experiment found that people can effectively distinguish negative and positive emotions from each other from a short description. However, further research is needed to find out whether humans can learn to perceive emotions only from contextual explanations.

Description
This study investigates the effects of familiarity and the size of a novel object on perception of depth. Familiar size is a visual depth cue that provides information about the distance of an object. This project explores if the familiar size illusion is a result of an automatic perceptual process or an intellectual thought process. This data was collected in two phases, a familiarization phase and a testing phase. The experimental participants were familiarized for 30 seconds with a novel object, while the control group was not shown any objects prior to presentation of test objects. The novel test stimuli were constructed in 5 sizes and participants in the familiar group were familiarized with the medium size object. Participants were then asked to indicate the perceived distance of different sized objects by moving a rod with a pointer at the end to match the distance. The smaller comparison objects subtended visual angles that participants had not previously experienced, while larger comparison objects produced a larger visual angle than the participants had seen during the familiarization phase. The testing phase was identical for both familiar and unfamiliar control groups. Apparent distance was influenced by the size of the objects. Larger objects were judged to be closer than the smaller objects. Participants not familiarized showed smaller effects of stimulus size than the familiarized group. The effect of familiarity was not significant for the smaller stimuli but was very significant for the larger stimuli. The results were not consistent with the cognitive theory which argues that familiar size is a result of a conscious thought process. These outcomes are predicted under the model of familiar size being an automatic perceptual process.

Description
Joseph Henrich coined the term WEIRD: Western, Educated, Industrialized, Rich, and Democratic to describe individuals who were noted to be the predominant sample subjects in psychology research studies and whose behavior is often used to represent behavioral studies (Henrich et al., 2010). Three distinctive conclusions were drawn from a review of a compilation of psychological and behavioral science research: massively biased samples – with approximately 96% of the experimental participants being drawn from northern Europe, North America, or Australia, and 70% of this subpopulation being American undergraduates; psychological diversity; and psychological peculiarity. In Henrich’s book, he discusses the points in history when the West began to differentiate themselves, psychologically speaking, from other cultures and the various driving factors that contributed to this change. Henrich emphasizes the narrowness of sampling within the psychological and behavioral sciences due to the nature of WEIRD societies. As such, it is difficult to generalize the normative ways of development in cross-cultural settings when there is a lack of representation for non-WEIRD societies. For example, shame is one of the vehicles that heavily influences non-WEIRD societies while guilt appears to be a driving factor in WEIRD societies. An idea that is guided by shame, “losing face,” is prominent in multiple non-WEIRD populations and may act as the driving force for adolescents to adopt ‘adult-like’ behaviors. Specifically, “migrant youth” is a phenomenon whereby youth from underdeveloped and developing nations leave some vestige of home to better themselves (Cortina et al., 2014). There is evidence to suggest that unaccompanied Latino migrant youth (LMY) in particular, live as “adults” despite being adolescents (Carlos Chavez et al., 2021). Whether their migration to the U.S. is motivated for a better life and future (Carlos Chavez et al., 2022) or as a family strategy (Stark & Stark, 1991) for the financial survival of the household, it may be possible that unaccompanied LMY are willing to sacrifice themselves in order to ‘save their parents’ face’ from poverty, hunger, and poor health. This type of ‘adult-like’ behavior among LMY challenges the normative human development literature and brings to surface the cultural implications and psychological consequences of non-WEIRD individuals who live in WEIRD societies.
