A Phenomenological Study Of School Psychologists: The Influence Of Implicit Bias On The Disproportionate Identification Rates Of African American Students Evaluated For Emotional Disturbance, Sonya Coe-Milo

Electronic Theses and Dissertations

As advocates, school psychologists remain ethically responsible and uniquely positioned to identify social injustices and promote nondiscriminatory practices in prekindergarten through grade 12 public education institutions. Implicit bias and its influence on African American students is one such practice. In public education, implicit bias contributes to discipline disproportionality, differentiated teacher support, pedagogical practices, and adult perceptions and expectations of appropriate and inappropriate behaviors. These factors directly correlate to the disproportionate identification rates of African American students for special education and related services. Therefore, this phenomenological qualitative study examined the personal, lived experiences and perceptions of school psychologists regarding implicit bias …

Reference Frames In Human Sensory, Motor, And Cognitive Processing, Dongcheng He

Electronic Theses and Dissertations

Reference-frames, or coordinate systems, are used to express properties and relationships of objects in the environment. While the use of reference-frames is well understood in physical sciences, how the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain the transition from egocentric (based on the observer) to exocentric (based outside the observer) reference-frames to account for the perception of relative motion. In a second project, we focus …

Digital Manipulation Of Human Faces: Effects On Emotional Perception And Brain Activity, Martin Knoll

Electronic Theses and Dissertations

The study of human face-processing has granted insight into key adaptions across various social and biological functions. However, there is an overall lack of consistency regarding digital alteration styles of human-face stimuli. In order to investigate this, two independent studies were conducted examining unique effects of image construction and presentation. In the first study, three primary forms of stimuli presentation styles (color, black and white, cutout) were used across iterations of non-thatcherized/thatcherized and non-inverted/inverted presentations. Outcome measures included subjective reactions measured via ratings of perceived “grotesqueness,” and objective outcomes of N170 event-related potentials (ERPs) measured via encephalography. Results of subjective …

Interrupting Holistic Processing May Improve The Detection Of Deceptive Emotional Facial Expressions, Christopher A. Gunderson

Electronic Theses and Dissertations

Although a growing body of evidence suggests that genuine and deceptive facial expressions differ, previous work is mixed as to whether observers can discern between them. One explanation is that cues to deception on the face are subtle and not readily perceived by observers. I argue that the way people process faces may obscure these cues, making them ‘unseen’ by observers. In the current work, I pit two hypotheses against each other to test whether interrupting holistic processing improves or impairs the ability to identify deceptive emotional expressions. Since people process faces holistically, one region of the face may interfere …

The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen

Electronic Theses and Dissertations

The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …

The Loss-Processing Framework, Lawrence Childress

Electronic Theses and Dissertations

The circumstances of responding to loss due to human death are among the most stressful experiences encountered in life. Although grief’s symptoms are typically considered essential to their gradual diminishment, possible negative impacts of complications related to grief are also well known, and have been associated with detriments to mental and physical health. Grief, however, can also generate transformative positive change. Thus, albeit ineludible, responding to loss is not uniformly experienced, expressed, or understood. It is also culturally-shaped, making attempts to define “normal” grief, as well as to label some grief “abnormal”—and to medicalize it—possibly problematic. Bereavement (the situation surrounding …

Database Of Picture-Based Cognitive Reappraisal Experiments: Analyses Of Trial-Level Factors, Damon Abraham

Electronic Theses and Dissertations

Cognitive reappraisal is widely recognized as an effective emotion regulation strategy for managing negative emotions. In laboratory research, reappraisal has been shown to attenuate self-reported negative affect as well as physiological and neurological markers of emotion and arousal. In these experiments, emotionally evocative images are frequently used to induce negative affect in participants. Depending on the trial condition, participants are instructed to either look and react naturally or to change their experience using reappraisal. Data are typically aggregated within trial condition, and the average difference in reported negative affect between conditions serves as the behavioral measure of reappraisal success. While …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

Electronic Theses and Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Medical Noncompliance In A Pediatric Patient Living In A Single-Parent Household, Lucy Obianuju Norrell

Electronic Theses and Dissertations

Abstract Noncompliance is a patient’s inability to comply with the recommended treatment for their complete recovery from an ailment, while compliance is the extent to which a patient adheres to the provider’s directive, such as medication and orders given. The purpose of this study was to determine if motivational interviewing when applied to noncompliant pediatric patients from single-parent households, would improve global medical compliance in this population as compared to the standard of care at the end of three months. Thirty-two participants were recruited using the homogeneous purposeful sampling. The project employed a mixed-method approach. Fred Kleinsinger’s noncompliant behavior tool …

Battle Over Black Bears: Investigating Perceptions Of The Black Bear Hunting Referendums In Maine, Francesca A. Gundrum

Electronic Theses and Dissertations

Human dimensions of wildlife is an emerging discipline that seeks to understand the complex relationships between people, wildlife, and their conflicts and/or interactions (Decker, Riley, & Siemer, 2012). Human dimensions utilizes several tested theoretical frameworks to investigate these complexities, such as cognitive hierarchy theory and wildlife value orientations (WVOs). Both of these theoretical frameworks were examined in this study, which investigated the content of news media during controversial American black bear (Ursus americanus) hunting referenda in Maine, and key stakeholder perceptions of black bear management. Maine is the only state that allows hunters to take a black bear over bait, …

Risk-Taking, Thinking Styles, And Criminality: A Fuzzy-Trace Theory Perspective, Adrienne Machann

Electronic Theses and Dissertations

Preferred modes of thinking, otherwise known as biases, have been well documented in adult reasoning and decision-making (Evans, 2003; Gilovich, Griffin, & Kahneman, 2002; Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). Researchers have explained these biases by proposing that the basis for them is a system of thought that relies mostly on intuition and “gut feelings” rather than logical analysis of the situation (Reyna & Brainerd, 2011; Tversky & Kahneman, 1986). According to standard dual-process theories, intuition is described as a thought process so quick, it is automatic and, at times unconscious; conversely, analytical thinking is slow and steady, …

Examining The Effects Of Energy Drinks On Academic Performance, Alyssa P. Roberson

Electronic Theses and Dissertations

Reports of energy drink (ED) consumption have grown among the United States population. Research suggests reasons for consumption vary across populations, including increased attention and enhanced endurance performance. However, ED consumers could suffer from negative effects of ED, including health problems, caffeine overdose, and death. Energy drink consumption is also linked to substance use. Despite risks of consuming ED, heavy use of EDs remains among college students, often to help with academic performance; however, research has not examined effects of ED consumption on perceived and actual academic performance. This study evaluated relationships among ED consumption, self-efficacy, and academic performance in …

Does Enhancing Mind Perception Affect Conspiracy Belief?, Jorge R. Noguera - Sepulveda

Electronic Theses and Dissertations

This study was conducted to determine the effectiveness of a novel mind perception manipulation. Mind perception is currently theorized to be an essential aspect of a number of human social psychological processes. Thus, a successful manipulation would allow for the causal study of those processes. This manipulation was created in an attempt to explore the downstream impact of mind perception on the endorsement of conspiracy theories. Conspiracy theories are steadily becoming more and more prominent in social discourse. Endorsement of conspiracy theories are beginning to show real world ramifications such as a danger to human health (e.g., in the anti-vaccination …

Wellness And Karate, Cristina Kumpf

Electronic Theses and Dissertations

The promotion of wellness is an integral part of the counseling field and is considered to be a central focus to the counseling process (Barden, Conley, & Young, 2015; Myers, 1992). The counseling profession adopted the concept of wellness because it harmonizes with many of the founding principles of the ACA and is seen as a process of questing toward optimal health and well-being in body, mind, and spirit (Barden, Conley, & Young, 2015; Myers, 1992; Myers, Sweeney, & Witmer, 2000). Additionally, ACA Code of Ethics (2014) state that counselors “engage in self-care activities to maintain and promote their own …

The Effects Of Monaural And Binaural Cues On Perceived Reverberation By Normal Hearing And Hearing-Impaired Listeners., Gregory Matthew Ellis

Electronic Theses and Dissertations

This dissertation is a quantitative and qualitative examination of how young normal hearing and young hearing-impaired listeners perceive reverberation. A primary complaint among hearing-impaired listeners is difficulty understanding speech in noisy or reverberant environments. This work was motivated by a desire to better understand reverberation perception and processing so that this knowledge might be used to improve outcomes for hearing-impaired listeners in these environments. This dissertation is written in six chapters. Chapter One is an introduction to the field and a review of the relevant literature. Chapter Two describes a motivating experiment from laboratory work completed before the dissertation. This …

The Effects Of One Neurofeedback Session On Eye-Tracking Distractibility When Completing Verbal And Visuospatial Search Tasks, Rebecca C. Recio-Swift

Electronic Theses and Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is a common and prevalent condition seen in all ages and throughout the world. School-aged and college-aged students seem to have the most difficulty in terms of academic performance, social functioning, and adaptive functioning. Visual attention and visual search are important aspects of attention. Visual attention drives what and how the brain processes and interprets information from the environment. Visual search is the ability to find a visual target within a set of distractors. Electroencephalography (EEG) Neurofeedback is the process of re-training brainwaves through operant conditioning. Neurofeedback (NF) has been suggested to be a non-invasive …

Effects Of One Neurofeedback Session On Relationship Between Fear-Of-Pain And Visual Avoidance Of Pain, Timothy Swift

Electronic Theses and Dissertations

Chronic pain is increasingly prevalent and costly and will continue to be with the increasing mean age of America’s population. It is important to identify interventions addressing pain-related biopsychosocial aspects. The purpose of the current study was to examine if a single session of specific neurofeedback (NF) protocols had an effect on subjective fear and physiological fear-avoidance behaviors in relation to pain-related stimuli. Correlational analyses revealed that FPQ-III minor pain scores were negatively associated with total fixation duration while looking at pain-related pictures. One-way ANOVAs revealed differences approaching significance for those trained on Left-Hemisphere NF protocols compared to those in …

Assessing The Relationship Between Talker Normalization And Spectral Contrast Effects In Speech Perception., Ashley Atri Assgari

Electronic Theses and Dissertations

Speech perception is influenced by context. This influence can help to alleviate issues that arise from the extreme acoustic variability of speech. Two examples of contextual influences are talker normalization and spectral contrast effects (SCEs). Talker normalization occurs when listeners hear different talkers causing speech perception to be slower and less accurate. SCEs occur when spectral characteristics change from context sentences to target vowels and speech perception is biased by that change. It has been demonstrated that SCEs are restrained when contexts are spoken by different talkers (Assgari & Stilp, 2015). However, what about hearing different talkers restrains these effects …

"Triggers": Systematic And Social Cues For Black College Student Racial Self-Consciousness And Rejection Sensitivity, Race-Based., Leanna T. Luney

Electronic Theses and Dissertations

Scholars have examined black student well-being in varying ways including through the framing of race-based rejection sensitivity (Downey & Feldman, 1996; Mendoza-Denton, Downey, Purdie, Davis, & Pietrzak, 2002) and racial self-consciousness (Clark & Clark, 1939). Research shows that black students perform worse academically when they display high levels of race-based rejection sensitivity and racial self-conscious levels (Brannon & Taylor, 2015; Clark & Clark, 1939; Koehler & Skvoretz, 2010), and feelings of racial self-consciousness or rejection sensitivity stem from discriminatory and prejudicial experiences. However, research has not fully connected the broader context surrounding black students in college to their high levels …

The Empathy Mitigation: Empathy And Its Impact On Pain Perception And Altruistic Motivation, Amanda Daly

Electronic Theses and Dissertations

Empathy and its impact on pain perception has been studied narrowly with the focus being on participants receiving empathy during a pain procedure. This study reversed the focus and ran a standard cold pressor test (CPT) in the context of an empathy frame structured to elicit an empathic response for others from participants. It was hypothesized that the group receiving the empathic frame would have longer CPT times due to alterations in pain perception from empathy activation and these subjects’ self-reported state-trait empathy level would positively correlate with the increased times. 85 subjects participated with a control group of 43 …

The Effect Of Religious Dress On Perceived Attractiveness And Trustworthiness, Courtney Swank

Electronic Theses and Dissertations

The hijab, a symbol of modesty and privacy in the Islamic faith, negatively affects ratings of perceived attractiveness. Although postcolonial feminism strives to portray women as not one universal group, but as an incorporation of different races, ethnicities, social classes, and other cultures, the Western world may not be where it endeavors to be. In this study the impact of the hijab on people’s perceptions of attractiveness was examined. Participants rated four target photos of the same woman with and without a hijab, and with or without cosmetics. Attractiveness and trustworthiness was then assessed in each condition, between genders, in …

The Effects Of Alcohol Priming On Age Perception And Attractiveness Ratings, Brooks B. Kolberg

Electronic Theses and Dissertations

Sexual assault and alcohol have often been linked together (Abbey et.al, 2004; Collins & Messerschmidt, 1993). Also, 29% of rape victims are between the ages of 12 and 17 (Greenfield, 1997). Research suggests people who are more impulsive are more likely to be sexually aggressive (Mouilso, Calhoun, & Rosenbloom, 2013); however, less is known regarding the underlying mechanisms of the relationship between alcohol and sexual assault of minors. This study addressed this knowledge gap by (1) examining the effects of alcohol priming on attractiveness ratings and age perception of individuals who could be perceived as adolescent, and (2) investigating the …

An Examination Of The Relationship Between Ethnic Identity Development, Cognitive Complexity, Differentiation Of Self, And Reports Of Racial And Ethnic Microaggressions, Deshae C. Gatti

Electronic Theses and Dissertations

Although individuals may not engage in racism consciously due to social undesirability, they may have biases that manifest in more subtle and unconscious ways. Research has found that people of color experiencing different racial and ethnic microaggressions in their everyday lives are subject to pervasive and negative impacts on their mental health, though little is known about the influence of one’s ethnic identity formation, affective processes, and cognitive processes. A multiple regression analysis was conducted to examine the degree to which ethnic identity development, cognitive complexity, and differentiation of self were associated reported experiences of microaggressions. The analysis indicated that …

Weight Stigma, Cognitions, And Disordered Eating, Sarah E. Pelfrey

Electronic Theses and Dissertations

Weight stigma experiences affect people of all weights and have many negative consequences; despite this, weight stigma is still an acceptable prejudice in our society. Research has established that weight stigma is predictive of disordered eating (DE) cognitions, which are, in turn, predictive of DE behaviors. The current study explored the unique contribution DE cognitions make to DE behaviors while controlling for other DE cognitions. The DE cognitions examined in the current study were drive for thinness, weight bias internalization, and perfectionism. The DE behaviors examined were emotional eating, restrained eating, inappropriate compensatory behaviors, and binge-eating. Weight bias internalization and …

Video Game Engagement, Gender, And Age: Examining Similarities And Differences In Motivation Between Those Who May Or May Not Play Video Games, Joseph Camarata

Electronic Theses and Dissertations

This research aims to fill a research gap by examining video games to explore whether gender, age, or hours played per week would exert any influence on the information of those who may or may not play video games. Mood Management Theory and Uses and Gratification Theory were used as the theoretical foundation for this study. Four-hundred-three East Tennessee State University students who received the survey via email were asked to voluntarily participate in a survey about their motivations behind playing video games. Results from MANOVA showed that the motivations of male participants on video games were significantly higher than …

Examining The Effects Of Enclosure Size At Training And At Test In Spatial Reorientation, Zebulon K. Bell

Electronic Theses and Dissertations

Previous research has begun to shed light on the differentiated influence of enclosure size on cue use during reorientation (Sturz, Forloines, & Bodily, 2012). Namely, the question remains of why both feature (i.e., objects or landmarks in the enclosure) and geometric (i.e., shape of the enclosure) cues are differentially affected by enclosure size, and the extent to which local (i.e., wall lengths and corner angles) and global (i.e., principal axis of space) geometric cues are affected by enclosure size. Further, it remains unclear whether training size, testing size, or the relationship between training and testing size influences the use of …

Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens

Electronic Theses and Dissertations

If an organism is trained to approach a location within an enclosure the organism will approach the correct location and it’s geometrically identical location within the environment upon removal of any features. This phenomenon has been turned spatial reorientation, and further studies on how, and to what, organisms reorient have conducted in the last several decades. In the reorientation literature, two theories have surfaced to fill the void left by the rejection of the initial reorientation theory, the Geometric Module theory. I attempt look to discern if the synonym judgement dual task will hinder reorientation in a similar or different …

The Effect Of Social Influence On Perception Of Tornado Warnings, Jason A. Parker

Electronic Theses and Dissertations

Tornado activity annually results in many deaths throughout the U.S. As a result, the emergency alert system (including tornado warnings) has made considerable advancements throughout the past few decades. However, continued improvements could be made to warning content that aid to facilitate adaptive decision-making by increasing individuals’ motivation to respond. One method that could increase adaptive responses to warnings is by including the modality of descriptive social information within the warning. Research suggests that normative social influence acts as a powerful motivator for individuals to conform toward the witnessed or perceived behaviors of others. The current study examined the impact …

Cognitive And Emotional Processes Involved In The Experience Of Objects As Holy Or Transcendent, Lotte J. Pummerer

Electronic Theses and Dissertations

In recent years, attitudes about religion/spirituality have become more pluralistic (Pew Research Center, 2015a). At the same time, the number of individuals who identify themselves as nonreligious, atheist or agnostic are growing (Pew Research Center, 2015b), yet we are lacking words and research to describe their attributions of transcendence in language not bound to religious concepts. This study aims at examining both concepts – holiness and transcendence – in their similarities and differences through assessing cognitive and emotional processes involved in experiences of objects.

The study consisted of two parts with a total of 206 Christian and 52 nonreligious/atheistic/agnostic participants. …

Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt

Electronic Theses and Dissertations

The aim of the current dissertation was to investigate the mechanisms that contribute to the emergence of causal perception in infancy. Previous research suggests that the experience of self-produced causal action may be necessary to promote the development of causal perception (Rakison & Krogh, 2012). The goal of the current study was two-fold: (1) to further explore the roles of self-produced action, haptic, proprioceptive and visual information, and parental interaction on young infants’ understanding of causality. To assess the impact of these factors on infants’ causal learning, 4½-month-olds were randomly assigned to one four conditions. Three of the conditions (Active …
