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.

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.

Development and Evaluation of an Electrical Engineering and Math Curriculum Module for High School Students

Description

Parents in STEM careers are more apt to guide their kids towards STEM careers (Sherburne-Michigan, 2017). There are STEM programs and classes for students who are interested in related fields, but the conundrum is that students need to be interested

Parents in STEM careers are more apt to guide their kids towards STEM careers (Sherburne-Michigan, 2017). There are STEM programs and classes for students who are interested in related fields, but the conundrum is that students need to be interested in order to choose to participate. The goal of this creative project was to introduce engineering concepts in a high school class to reveal and investigate the ways in which engineering concepts can be successfully introduced to a larger student populace to increase interest in engineering programs, courses, and degrees. A lesson plan and corresponding materials - including circuit kits and a simulated ball launching station with graphical display - were made to accomplish this goal. Throughout the lesson students were asked to (1) use given materials to accomplish a goal, (2) predict outcomes based on conceptual understanding and mathematical calculations, (3) test predictions, (4) record data, and (5) analyze data to generate results. The students first created a simple circuit to understand the circuit components and learn general electrical engineering concepts. A simple light dimmer circuit let students demonstrate understanding of electrical concepts (e.g., voltage, current resistance) before using the circuit to a simulated motor in order to launch a ball. The students were then asked to predict the time and height of a ball launched with various settings of their control circuit. The students were able to test their theories with the simulated launcher test set up shown in Figure 25 and collect data to create a parabolic height versus time graph. Based on the measured graph, the students were able to record their results and compare calculated values to real-world measured values. The results of the study suggest ways to introduce students to engineering while developing hands-on concept modeling of projectile motion and circuit design in math classrooms. Additionally, this lesson identifies a rich topic for teachers and STEM education researchers to explore lesson plans with interdisciplinary connections to engineering. This report will include the inspiration for the product, related work, iterative design process, and the final design. This information will be followed by user feedback, a project reflection, and lessons learned. The report will conclude with a summary and a discussion of future work.

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.

Analog to Digital Converters (ADCs) are a critical component in modern circuit applications. ADCs are used in virtually every application in which a digital circuit is interacting with data from the real world, ranging from commercial applications to crucial military and aerospace applications, and are especially important when interacting with sensors that observe environmental factors. Due to the critical nature of these converters, as well as the vast range of environments in which they are used, it is important that they accurately sample data regardless of environmental factors. These environmental factors range from input noise and power supply variations to temperature and radiation, and it is important to know how each may affect the accuracy of the resulting data when designing circuits that depend upon the data from these ADCs. These environmental factors are considered hostile environments, as they each generally have a negative effect on the operation of an ADC. This thesis seeks to investigate the effects of several of these hostile environmental variables on the performance of analog to digital converters. Three different analog to digital converters with similar specifications were selected and analyzed under common hostile environments. Data was collected on multiple copies of an ADC and averaged together to analyze the results using multiple characteristics of converter performance. Performance metrics were obtained across a range of frequencies, input noise, input signal offsets, power supply voltages, and temperatures. The obtained results showed a clear decrease in performance farther from a room temperature environment, but the results for several other environmental variables showed either no significant correlation or resulted in inconclusive data.

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.
