The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay …

Simulated Owl Predation During Foraging Differentially Alters Choice And Fear Behavior Between Sex In Rats, Meghan M. Olsen

Research Psychology Theses

Existing research on the predator cue circuit has indicated there are observed differences between sexes of animals either directly or indirectly exposed to a predator stimulus. Exposure increases predator directed attention, and overrides other motivational systems (hunger, pain, reproductive behavior). Little research has explored whether exposure to predation is associated with differential responses to non-predator related decision-making across a variety of tasks. Therefore, understanding the prioritization of motivational states when a predator stressor is present can aid in understanding sex differences in these processes in both adaptative and maladaptive conditions. To determine how repeated exposure to a predator stressor differentially …

Does Trait Self-Esteem Serve As A Resilience Factor In Maintaining Affective Well-Being? Findings From Daily Diary Studies In Singapore And The United States, Matthew H. S. Ng, Verity Y. Q. Lua, Nadyanna M. Majeed, Andree Hartanto

Research Collection School of Social Sciences

Research suggests that self-esteem could be a protective factor in stressful or unfavorable situations. However, little research has been done on the buffering role of self-esteem in the context of daily stressors on affective reactivity. Three daily diary studies (of which two were conducted in Singapore and one in the United States) were carried out to examine this relationship. In all three studies, trait self-esteem was measured at baseline. Subsequently, daily assessment was conducted on exposure to daily stressors, and positive and negative affect for seven to eight days. Multilevel modeling showed that trait self-esteem did not moderate the relationship …

Cognitive Consequences Of Covid-19 Infection And Quarantine-Induced Social Isolation: Hope For The Young And Mildly Infected, Kristin Nickole Kirchner

Theses and Dissertations

Coronavirus disease 2019 (COVID-19) has infected over 539 million individuals worldwide, and initial research supports the possibility that COVID-19 may damage the central nervous system either directly or indirectly. Neurological signs and noted cognitive deficits observed in even mildly infected patients are a cause for concern for those infected by COVID-19; the effect of social isolation on the central nervous system is also of interest. The present study sought to determine the extent of these potential cognitive deficits in a young and mildly infected sample of college students. Participants completed an extensive survey assessing their experience with COVID-19 and any …

The Influence Of Parental Psychological Control On Offspring Anxiety Symptomatology: A Cognitive Model, Yu Ping Wong

Dissertations and Theses Collection (Open Access)

Parental control has often been purported to be a risk factor for offspring anxiety. Recent studies however, identify that a particular dimension of control - parental psychological control - is an especially important contributor to anxiety. However, the mechanisms behind this relationship remain unknown. Thus, in this study, we seek to bridge this gap in the literature by examining whether a cognitive mechanism underlies this relationship. Drawing on Beck's model of emotional disorders, we propose that control- related beliefs and negative automatic thoughts would serially mediate the influence of psychological control on anxiety symptoms. Moreover, we sought to examine the …

Sex Differences In Locomotor Activity And Behavioral Sensitization In Rats Administered Fentanyl, Jessica J. Lee, Nareen Sadik, Cameron Davidson Phd, Majd Yahya, Josie Zdun, Shane Perrine Phd

Medical Student Research Symposium

Opioid overdoses have continued to increase, and women have experienced a greater rate of increase than males. Preclinical studies demonstrate marked sex differences in addiction-related behaviors, with females being more vulnerable due to a potential role of estradiol. We sought to understand how the estrous cycle, as a proxy measure of estradiol, influences sex differences in the sensitizing effects of fentanyl. In this ongoing study, we used male and female rats to investigate potential sex effects of fentanyl (20µg/kg subcutaneously) administration for 14 days and a forced abstinence period of 13 days on behavioral sensitization via locomotor activity (LMA) following …

Comparing Crime Scene Trajectories: Sexual Versus Nonsexual Serial Homicides, Jonathan T. Dixon

Student Theses

When faced with a possible serial offender, crime linkage analysis is crucial in identifying which crime scenes belong to the same offender. Thus, when analyzing behavioral consistency to link crimes, it is essential to use a classification model that is empirically tested and is based on the type of crime being investigated. Several classification models examine patterns of consistency and change using a combination of thematic and behavioral subgroups; however, they are tested using sexual and nonsexual crime scenes, which some recent literature argues are two distinct types of homicide and should be examined separately. The present study tests the …

The Interplay Between Perceived Usability And Quality In Visual Design For Tablet Game Interfaces, Uttam Kokil, Tracy Harwood

Faculty and Research Publications

Research in human-computer interaction (HCI) has shown inconsistencies in the relationship between users’ perception of usability and the quality of visual design in digital products. Research is lacking in the gaming domain for visual design in user interfaces on tablet screens. Despite extensive research on visual aesthetics and perceived usability, best practices offer limited guidance for game interfaces from a user-centered design perspective.

The objectives of this study are twofold: to employ a design-oriented methodology to create a real iOS tablet game app from start to finish using ideation, focus groups, iterative prototyping, usability testing, and empirically evaluating game participants’ …

A Comparison Of Fixed Pay, Piece-Rate Pay, And Bonus Pay When Performers Receive Tiered Goals, Alejandro Ramos

Dissertations

The purpose of this study was to compare the performance of participants under three pay systems when all were given five tiered goals. Seventy-one undergraduate students were randomly assigned to receive either fixed pay, base pay with bonuses, or piece-rate pay. Over the course of six 45-minute sessions, one of which served as a covariate, participants engaged in a computerized simulated medical record data entry task. The primary dependent variable was the average number of correctly completed medical records per session. An increasing relationship was expected to be found between the three groups with respect to the number of correctly …

Effects Of Chronic Stress On Safety Processing And Physiology In The Medial Prefrontal-Amygdala-Basal Forebrain Circuit, Itamar S. Grunfeld

Dissertations, Theses, and Capstone Projects

Chronic stress increases generalization of fear to non-threatening cues, a key symptom in numerous psychiatric mood disorders. However, the mechanisms through which stress impacts safety learning remain poorly understood. To probe the relationship between stress and safety learning, this dissertation employed multiple behaviors, in conjunction with in-vivo multisite physiology during explicit safety and fear discrimination learning. In Chapter 1, I outline the role of chronic stress in driving neurological adaptations that result in generalized fear and highlight how this occurs because of impaired safety cue encoding. In Chapter 2, I show that chronic stress in the form of social defeat …

Withdrawal From Voluntary Oral Methamphetamine Reveals Female Specific Susceptibilities To Behavioral Deficits And Neurochemical Perpetuators Of Neurotoxicity And Drug Seeking Behavior, Nicoletta K. Memos

Dissertations, Theses, and Capstone Projects

MA is a potent, highly addictive psychomotor stimulant known to produce neurotoxic effects on the brain leading to neurological impairments^1-6 characterized by neurodegeneration of dopaminergic fibers, cell bodies and pathways, as well as brain regions such as the hippocampus, frontal cortex, and midbrain^1,5.

In MA addiction, women are more vulnerable to the behavioral and cognitive effects of MA compared to men. Adult human literature reveals gender differences in usage patterns and women demonstrate increased vulnerability to the neurotoxic effects and health effects of MA use. Women begin drug use at an earlier age, escalate drug use quicker, …

Exploring The Effectiveness Of Multiple-Exemplar Training For Visual Analysis Of Ab-Design Graphs, Verena S. Bethke

Dissertations, Theses, and Capstone Projects

In behavior analysis, data are usually analyzed using visual analysis of the graphed data. There are a wide range of methods used to visually analyze data, from a basic ‘textbook’ style approach to the use of visual aids, decision-rubrics, and computer-based approaches. In the literature, there have been some comparisons of the efficacy of different approaches. Visual analysis as a behavior can be taught using a variety of methods, independent of how the skill itself is to be performed. Teaching methods include lecture, online instruction, and equivalence-based instruction. There is not much research on the teaching of visual analysis specifically, …

Combining Non-Traditional Therapeutic Competencies With Dance/Movement Therapy In Response To Client Reactivity: The Development Of A Method, Nicole Koontz

Expressive Therapies Capstone Theses

Individuals with reactive attachment disorder present as guarded towards therapeutic care and respond passively to treatment or become combative and aggressive. Previous body-based interventions for individuals with reactive attachment disorder included dangerous and unethical approaches that led to traumatization, distrust, and even death. Historical attachment therapies focused on making the client feel powerless and hopeless to accept care rather than practitioners adjusting to individualized client-centered care. A dance/movement therapy-informed method was developed to provide a nonthreatening therapeutic space to foster genuine participation for clients who present with reactivity towards treatment. The method was implemented over the course of seven weeks …

God’S Plan For Life: Training Drill Sergeants To Better Serve Their Neighbor By Developing Moral Character Utilizing The “Transformational Moral Leadership” Model, Matthew Christensen

Doctor of Ministry Major Applied Project

Instances of moral failure within the U.S. Army raises the question of whether an individual’s character may be developed and improved by utilizing a moral decision-making process. If so, is it possible to measure this improvement? From a Lutheran perspective, is it possible to improve moral character without appealing to the boundaries provided by God’s Word and a Christian community influencing the spiritual dimensions of one’s life.

This project set out to build upon an eighteen-hour Transformational Moral Leadership training model being utilized to strengthen the moral character of drill sergeants at Fort Benning, Georgia. The project allowed me as …

Perfectionism, Alcohol Intoxication, And Deliberate Self-Harm In Men And Women, Lissa N. Mandell

Theses and Dissertations

Previous research has demonstrated associations between deliberate self-harm (DSH) and perfectionism, although most of that research used retrospective self-report measures of DSH, which are prone to various cognitive biases. Although perfectionism has been associated with alcohol abuse, no research has examined how alcohol intoxication may moderate the relation between perfectionism and DSH. The aims of this experimental study were to determine if perfectionism is associated with a laboratory analogue of DSH (the Self-Aggression Paradigm) and examine the role of alcohol intoxication as a potential moderator. Using archival data, blood alcohol content (BAC) was manipulated by randomly assigning participants to reach …

Does Optic Flow Provide Information About Actions?, Hannah Masoner

Dissertations

Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …
