Threat Detection From Phenotypic Facial Features, Melissa L. Kern

Theses and Dissertations

Previous research has demonstrated people's ability to accurately and quickly make snap judgments of trustworthiness from viewing individuals' faces (Todorov, Pakrashi, & Oosterhof, 2009; Willis & Todorov, 2006). The study of how human beings make meaningful predictions from phenotypic facial features about trustworthiness, among other traits, warrants additional scrutiny and investigation. Further, other research suggests the facial width to height ratio (fWHR) is a more specific indicator used by human beings to gauge, often accurately gauge, trustworthiness with some accuracy. As such, past research found participants rated people with larger fWHRs as less trustworthy and more aggressive (Carré & McCormick, …

Posttraumatic Growth And Primal World Beliefs Among People Who Have Caused Accidental Death Or Serious Injury, Mark L. O'Brien

Master of Applied Positive Psychology (MAPP) Capstone Projects

Background. Posttraumatic growth (PTG)—positive changes that people may experience in the aftermath of highly distressing experiences—has been observed in survivors of a variety of events but has not been previously studied among people who have caused accidental death or injury (PCADIs). In addition, questions remain about the role, in PTG, of changes in the assumptive world and the relationships between PTG and distress, personality, and social support. Methods. Participants (N = 528), included PCADIs (n = 44) and a non-trauma comparison group (n = 484), who completed the Primals Inventory and measures of personality, anxiety, and depression. …

The Effects Of Flood Warning Information On Driver Decisions In A Driving Simulator Scenario, Katherine Rose Garcia

Psychology Theses & Dissertations

Flood warnings are a type of risk communication that alerts the public of potential floods. Flood warnings can be communicated through mobile devices and should convey enough information to keep the user safe during a flood situation. However, the amount of detail included in the warning, such as the depth of the flood, may vary. The purpose of this study was to: (a) extend our prior research on flood warnings by recreating the written driving scenarios into the driving simulator; (b) deepen the understanding of human decision-making in risky situations; and (c) investigate how to best inform drivers of floods …

Hurting To Helping: Regret As A Potential Motivator Of Helping Behavior, Chandler Ann Findley

Graduate Theses and Dissertations

Previous research has suggested that emotions can influence people’s motivation to engage in prosocial behaviors. Even negatively-valenced emotions, like sadness, guilt, and shame, have been shown to motivate prosocial behaviors. Exploratory analyses of a previous study indicated that regret may also motivate increased prosocial intentions, but no research has been published to experimentally test whether feelings of regret may motivate prosocial behaviors. Therefore, the present research seeks to experimentally manipulate participants’ current emotional state to empirically examine whether regret motivates greater helping behavior than other, similar negative emotions that have already been demonstrated to motivate prosocial behaviors in humans. These …

Can Conflict Cultivate Collaboration? The Positive Impact Of Mild Versus Intense Task Conflict Via Perceived Openness Rather Than Emotions, Tsai Ming-Hong

Research Collection School of Social Sciences

Public Significance Statement In contrast to previous research on the negative associations between conflict and collaboration, the current investigation demonstrates the positive effects of conflict on collaboration and performance and offers practical suggestions on beneficial conflict expressions. Specifically, when people debate and deliberate about their different viewpoints about task-related issues, they tend to collaborate and thus achieve high task performance by enhancing their perceptions of others' openness rather than by influencing their emotions.Previous research has demonstrated negative associations between task-relevant conflicts and collaboration. To supplement the previous findings and explore the potential benefits of conflicts, we differentiate between two types …

Temperament And Individual Differences In Category Learning, Tianshu Zhu

Electronic Thesis and Dissertation Repository

Objectives. Individuals can differ in their strategic approach in learning the same categorization task, researchers have sought to study what specific stable individual differences traits can help explain these differences. This dissertation first surveyed extant literature on the impact of trait differences on category learning then examined the effect of temperament traits on these dependent variables. Chapter 2 (scoping review): This scoping review synthesized the past literature that examined the relationship between sources of stable individual differences and category learning performance and strategy use outcomes. Five database platforms were searched to identify relevant articles, cross-referencing was also performed. Sixty-nine studies …

Mementos And The Endowment Effect, Charlene K. Chu, Suzanne B. Shu

Business Faculty Articles and Research

This research provides evidence for a new moderator of the endowment effect: having a memento of the endowed object. Three studies adapting classic endowment effect paradigms and using a variety of endowment objects and mementos demonstrate that having a memento of an endowment increases willingness to trade the endowment and decreases selling prices for the endowment. We provide evidence that mementos attenuate the endowment effect regardless of whether the memento is a separate small gain when facing the loss of the endowment or a small part of the original endowment that is kept. Examining mementos in context of the endowment …

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 …

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 …

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 …

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 …

These surveys had questions relating to alcohol usage, marijuana usage, mood, pain, and questions about daily functioning. …

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

Faculty 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 …

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, …

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 …

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, …
