Does Chronically Administered Intermittent Restraint Stress (IRS) have Long-Lasting Effects on Fear Extinction and Depressive-Like Behavior?

Description

The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks.

The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks. Young adult, male Sprague Dawley rats underwent restraint stress using wire mesh (6hr/daily) for five days with two days off before restraint resumed for three weeks for a total of 23 restraint days. The groups consisted of control (CON) with no restraint other than food and water restriction yoked to the restrained groups, stress immediate (STR-IMM), which were restrained then fear conditioned soon after the end of the IRS paradigm, and stress given a rest for 6 weeks before fear conditioning commenced (STR-R6). Rats were fear conditioned by pairing a 20 second tone with a footshock, then given extinction training for two days (15 tone only on each day). On the first day of extinction, all groups discriminated well on the first trial, but then as trials progressed, STR-R6 discriminated between tone and context less than did CON. On the second day of extinction, STR- IMM froze more to context in the earlier trials than compared to STR-R6 and CON. As trials progressed STR-IMM and STR-R6 froze more to context than compared to CON. Together, CON discriminated between tone and context better than did STR-IMM and STR-R6. Sucrose preference, novelty suppressed feeding, and elevated plus maze was performed after fear extinction was completed. No statistical differences were observed among groups for sucrose preference or novelty suppressed feeding. For the elevated plus maze, STR-IMM entered the open arms and the sum of both open and closed arms fewer than did STR- R6 and CON. We interpret the findings to suggest that the stress groups displayed increased hypervigilance and anxiety with STR-R6 exhibiting a unique phenotype than that of STR-IMM and CON.

Effect of Student Relationships and Motivation on Student Learning and Teacher Lessons

The fields of psychology and education are typically housed within separate contexts. Psychology is the scientific study of the mind, thoughts, behaviors and actions (Nordqvist, 2018). The history of psychology originated centuries ago in Europe, although some attribute the beginning of mind study as far back as Aristotle. Currently, the American Psychological Association has 54 active scientific divisions, ranging from the Society of Military Psychology to Psychological Hypnosis. Education, has been studied in a variety of ways, including curriculum, instruction, and educational policy. Educational psychology is a relatively new field that examines the effects of how psychological science can be applied to learning and educational success (Parankimalil, 2014). Some of the factors that educational psychologists study include: educational reform, classroom interactions, stimuli effects on learning, student motivation, individual and collective self-beliefs, goal orientation, theory of attribution, and cognitive development. It is important to distinguish that each student has a unique approach to learning. Student relationships in classrooms can profoundly impact this learning. Moreover, student motivation stems intrinsically and is influenced by external factors. Research demonstrates the positive effects sensory stimuli, including auditory, tactile, olfactory and visual, can have on student learning as well. Intrinsic and extrinsic motivation are inseparable facets of student learning, as explained by the self-determination theory. This allows for student progression from external to internal motivation, to develop better learning methods. Educational psychology is very relevant to study today, more so in a classroom where students are actively synthesizing the information learned, to apply it to real-world situations. Future research includes studying cultural effects, technology, stereotypes and reciprocal determinism in an educational setting and providing individualized learning opportunities. This research provides a transition to a student focused change rather than the cyclical model currently driving the education system today. By studying the psychological effects in a classroom, the goal is to reduce the dropout rate and improve child and adolescent education by personalizing learning.

Free Bird: Preventing Sexual Assault on College Campuses

Sexual assault affects hundreds of thousands of individuals every year. College students are especially at risk as women ages 18-24 are 3 times more likely to be a victim of sexual assault than other females (Campus Sexual Violence, n.d.). Because victims of sexual assault can experience negative sequelae for weeks, months, and even years after the incident occurs, it is critical to provide them with easily accessible help and guidance. For my thesis project, I investigated how sexual assault influences these victims' lives as well as what help is readily accessible to them. After researching sexual assault in college students and reading through many websites, articles, and journals, I researched the types of information provided to sexual assault victims through the websites of national sexual violence organizations. I then coded the websites of Arizona colleges and universities (N = 10) for the topics covered in their sites. Because several of these colleges had inadequate material on their websites, I developed a website that would provide additional information to sexual assault survivors. The idea of Free Bird is to establish a safe space for victims of sexual assault to find information that will allow them to heal along their journey. I learned a lot while completing this project, and I hope that the creation of this website will allow others to become more educated on the topic and realize what a problem sexual assault is in our society today.

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.

A Comparison and Contrast of Animal Psychology in the Wild vs. the Human Dominated World

Animal psychology is the study of how animals interact with one another, their environment, and with humans. This can be done in two different settings, the wild and captivity, and through two different approaches, academic research and practice. Academic research relies primarily on behavioral observation for data collection. Practice uses behavioral observation as well, but allows for a more hands on experience and lets the practitioner make improvements in the quality of life. I interviewed two people, one who practices in captivity, and one who does research in the wild. Dr. David Bunn has done research on wild animals in Kruger National Park in South Africa for over twenty years, studying human-animal interactions. Hilda Tresz has worked in zoos nearly forty years and specializes in chimps. Working within the same field, but utilizing a different setting and approach makes a big difference in the feel of the job. Though I found many differences between the two by doing my own research and from conducting interviews, there are many similarities to note as well. The general field of animal psychology is very rewarding, requires a lot of patience, and leads to a better understanding of animal behavior and how to care for specific species of animals. Working with captive animals allows for the opportunity to make a big difference in animal's lives through behavioral enrichment and general care. Working in the wild allows us to understand the innate animal behaviors displayed. Through practice, people get more hands on experience; while through research, you get to observe animals in their native habitats. Each setting and approach has it's own benefits depending on what each person's goals are for their job.

Abstract
This study investigates the effects of Bharatanatyam dance on stress, mood, and anxiety. I have danced Bharatanatyam since I was 8 years old, it has offered me a way to release stress and anxiety. This study provides empirical data to support the claim that Bharatanatyam has therapeutic effects that release stress and reduce anxiety. This investigation was conducted through self-reports and interviews. A Positive Affect and Negative Affect Schedule (PANAS) scale was used to determine positive and negative effects. The average positive affect during the “dance weeks” (DW) was 46.6 and the average negative affect was 12.2. During the “no dance weeks” (NDW), the average positive effect was 23.7 and the average negative affect was 31. The participant’s interview PANAS results had an average positive effect of 39.8 and an average negative effect of 12.8. Analyzing the self-report journaling highlighted a more prevalent use of positive words during the DW and a more significant use of negative words during the NDW. The Bharatanatyam dancers who were probed to enter post-performance environment for an interview also used positive words to describe Bharatanatyam dancing. In conclusion, practicing Bharatanatyam had an overall positive effect on mood, and can reduce stress and anxiety.

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.

The Wham-Womb Effect: Words with the Phoneme /æ/ are Rated as More Rousing than those with /u/

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.

Abstract White matter thickness correlates with various mental illness. Commissure white matter tracts are responsible for interconnecting the same cortical area in both hemispheres. Injury to the brain can result in thinning and shrinkage even collapsing and detachment of the white matter tracts' myelin sheaths. Injury can affect cognitive function and time points are essential for therapeutic intervention. Research is beginning to identify gradual long-term neurodegenerative effects. With the advancement of brain imaging technology, we know that Wallerian degeneration has a significant negative impact on the white matter tracts throughout the brain (Johnson, Stewart, & Smith, 2013). If major tracts become injured like, the corpus callosum, then it can affect interhemispheric communication. Once myelin is damaged the axon becomes vulnerable, and the mechanisms of nerve recovery are not well known. Myelin sheath recovery has been studied in hopes to proliferate the oligodendrocytes that make up for the atrophied myelin. Neurotoxic chemicals released at activation of macrophages which hinders the brains ability to proliferate myelin protein needed for myelin differentiation adequately. In the central nervous system myelin has mechanisms to recover. Neurogenesis is a naturally occurring recovery mechanism seen after brain injury. Understanding the time points in which brain recovery occurs is important for treatment of diffuse injuries that cannot be identified through some imaging techniques. To better understand critical timepoints of natural recovery after brain injury can allow further investigation for early intervention to promote adequate recovery.

Token economies are a type of behavioral reinforcement that are particularly useful in classroom settings for increasing student compliance, for both typically developing children and children with autism spectrum disorder. During this study, we implemented a token economy in an inclusive preschool classroom with tokens contingent on compliance to classroom rules. Three participants, two with a diagnosis of autism spectrum disorder and one considered typically developing, were included in the study. Results indicated that levels of compliance increased for both the typically developing participant and participants with autism, and did not drop below baseline levels during the withdrawal phase, suggesting there was no lack of intrinsic motivation. Further, the typically developing participant and one of the participants with autism spectrum disorder had very similar levels of compliance, while the other participant had much higher levels of compliance throughout every phase, suggesting that the compliance levels for peers with more advanced repertoires with autism may differ from both typically developing peers and peers who have less developed repertoires. The implications of these results are discussed as they relate to compliance from an ABA perspective.
