Description
Chronic stress is a risk factor for many diseases that impact the brain, including Alzheimer’s Disease. Unlike acute stress, chronic stress reduces neuronal plasticity, which can lead to neuronal remodeling and suppression. This project investigates the effect of stress on the dendritic complexity of hippocampal neurons in rats, demonstrating a methodology for procuring and analyzing these neurons. The brains of the 160 rats from the Sustained Threat and Timing (STAT) experiment were frozen. The STAT experiment investigated the effect chronic variable stress had on prospective and retrospective timing in rodents. Using a cryostat, thin coronal slices of brain tissue were placed on microscopic slides. The tissue samples were then stained using the Golgi method of silver staining. Hippocampal neurons were assessed using Sholl Analysis; the dendritic complexity of these neurons was quantified. The method of using Sholl Analysis was found to be an effective process in measuring dendritic length of hippocampal neurons.

Description
A review of current research on the relation between growth mindset and students with disabilities was completed. The goal for this project was to provide support for the idea that cultivating the growth mindset of students with disabilities could result in better academic outcomes and an overall improvement in the students’ lives including but not limited to self-efficacy skills, motivation, and dedication. Findings were used to design an evidence-based workbook for cultivating growth mindset in college students with disabilities.

Description
Recent findings support that facial musculature accounts for a form of phonetic sound symbolism. Yu, McBeath, and Glenberg (2019) found that, in both English words and Mandarin pinyin, words with the middle phoneme /i:/ (as in “gleam”) were rated as more positive than their paired words containing the phoneme /ʌ/ (as in “glum”). The present study tested whether a second largely orthogonal dimension of vowel phoneme production (represented by the phonemes /æ/ vs /u/), is related to a second dimension perpendicular to emotional valence, arousal. Arousal was chosen because it is the second dimension of the Russell Circumplex Model of Affect. In phonetic similarity mappings, this second dimension is typically characterized by oral aperture size and larynx position, but it also appears to follow the continuum of consonance/dissonance. Our findings supported the hypothesis that one-syllable words with the center vowel phoneme /æ/ were reliably rated as more rousing, and less calming, than matched words with the center vowel phoneme /u/. These results extend the Yu, et al. findings regarding the potential contribution of facial musculature to sounds associated with the emotional dimension of arousal, and further confirm a model of sound symbolism related to emotional expression. These findings support that phonemes are not neutral basic units but rather illustrate an innate relationship between embodied emotional expression and speech production.

Description
Psychology and dance both shed light on the question: how do our personal, life experiences affect our movement? This document introduces elements from psychology and dance through associative learning, attachment styles, muscle patterning, and partner improvisation as ways of exploring this question. It aims to briefly introduce these theories and explain how they had a role in the research of the creative project. It also documents the inception, creation, and production of Lullabye, a dance work intended to be accessible to an audience with little to no experience viewing concert dance, with the target audience specifically being the writer’s mother. It has three sections, each featuring a different element of dance, storytelling, and individuality. It starts a conversation on how emotions and thoughts related to personal experiences can affect our movement.

Description
Music and emotions have been studied frequently in the past as well as music and memory. However, these three items don’t have as much research grouped together. Further, this research does not also encompass culture. In my research, the aim was to examine the relationship between music, memory, emotion, and culture of gender. The hypothesis was that women had more emotions linked to music than men. We gave 416 students an animal fluency task, a letter fluency task, six cultural fluency tasks, and a cultural identity survey. We used a t-test and created a graph to analyze my data. After administering my tasks, we found that women had recalled more adjectives linked to music than men. However, there was not a statistically significant difference between the number of adjectives with emotional valence between men and women, indicating that there was no relationship between gender and emotion in regards to music. The limitations on this study included the descriptions on how to complete the task, the cultural norms of the participants, and the disparity between the number of female and male participants. In a future study, it is necessary to be more specific in what is desired from the participants and to pay close attention to shifting gender norms. Further, we would also like to see how the results from future research can impact music therapy for memory-related mood disorders.

Description
It was hypothesized that information about current romantic involvement could make a male target more attractive to females. A 2 (Gender) X 4 (Romantic Involvement: Current Romance, Past Romance, Friend, and Control) factorial design was created to test competing predictions from scarcity/reactance, impression-formation, and sociobiological perspectives. A total of 235 male and female subjects saw a photograph of an opposite gender target person, then read a brief description about the target that contained one of the three involvement manipulations, or contained no involvement manipulation (Control). Subjects then rated the target along a 14 item scale to measure romantic attraction. ANOVA and MANOVA results revealed main effects of Gender and Romantic Involvement. Simple effects for Romantic Involvement were found for female, but not male subjects. A priori contrasts testing the predictions from the competing theoretical perspectives provided support only for the socio-biological prediction for female subjects.

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
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.

Description
Besides acquiring group status via dominance or force, as in other animals, human beings can acquire status via prestige, which follows from other group members valuing one’s expert knowledge. Past research has shown a preference for prestigious leaders over dominant leaders. That is, people prefer leaders who are expert over those who are domineering. In this research, I explored whether the preference for prestige over dominance applies to preferences for actual political figures with facial features that appear dominant or prestigious. I also asked whether the same links between dominance, prestige, and voter preference would hold for both men and women. American participants (recruited through Amazon Mechanical Turk) rated European politicians’ faces on traits associated with prestige and dominance and indicated their likelihood of voting for this person as a governor of their state. Findings suggest ratings of both prestige is a strong predictor of leadership preference than dominance. However, strong correlations between variables suggest prestige and dominance are two closely related concepts. In addition, participants indicated a marginal to significant preference for female leaders, depending on their perceived dominance and prestigiousness.

Description
The locus coeruleus-norepinephrine system (LC-NE) has been argued to play a vital role in task engagement and attention control by the adaptive gain theory (Aston-Jones & Cohen, 2005). One of the central claims of this theory is that tonic LC activity exhibits a quadratic relationship with task performance. Pupil dynamics have been correlated to LC-NE activity via primate intracranial recordings in ways that provide evidence for the adaptive gain theory. Due to the small size and location of the LC, less is known about LC functioning in humans, leading to a desire to find valid, noninvasive psychophysiological proxies to study this structure. In this paper we performed a replication of Murphy, Robertson, Balsters, & O’Connell (2011) to gather evidence on whether pupil fluctuations and the P3 event-related potential are viable markers for measuring tonic and phasic LC-NE activity in humans. A sample of 33 subjects from the Arizona State University human subjects pool provided usable electroencephalogram and pupillometry data collected during an auditory oddball task. Our analyses largely correspond with those found in Murphy et al. (2011) showing some evidence that pupillometry and P3 can be utilized when studying the LC. Moving forward we will reproduce the full set of analyses from Murphy et al. (2011) with our dataset.
