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 …

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. …

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 …

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 …

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 …

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 …

The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson

Electronic Theses and Dissertations

Acute stress is commonly experienced by many throughout their lives. Given the demanding lifestyle of many career paths, it's important to gauge the influence of these stressors upon cognitive performance. The present dissertation focus' upon explicit learning in attempts to explore one avenue of the stress-cognition relationship. The Trier Social Stress Test (TSST) was used as a lab stressor for Experiments 1 and 2, in which participants are asked to give a speech and complete a difficult math task in front of 2 evaluators trained to monitor non-verbal behavior. Experiment 1 investigates the dynamic stress response during the minutes following …

Tornado Trouble: How Can Current Tornado Warnings Be Improved?, Jonathan P. Evans

Electronic Theses and Dissertations

There are many unnecessary deaths from tornadoes every year (NOAA.org, 2013). Although there have been great advancements in tornado warning systems (Coleman, Knupp, Spann, Elliot, & Peters, 2010), more changes to systems could be made to motivate people to take action in preparation for tornadoes (Brotzge & Donner, 2013). Protection motivation theory outlines the process by which we assess threats and decide whether or not preventative actions are worth performing. If the threat is perceived as severe enough and the preventative actions are seen as capable of mitigating the threat, the individual is motivated to act (Rogers, 2000). One means …

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan

Electronic Theses and Dissertations

Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …

The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws

Electronic Theses and Dissertations

A qualitative investigation was conducted to explore the phenomenon of abstract cognition among a purposive sample of 5 secondary scholastic chess club participants. The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

Ego Depletion And Boredom: Does Boredom Compromise Future Acts Of Self-Control?, John Lemay

Electronic Theses and Dissertations

This study explored how boredom might influence self-control when participants believed that willpower is unlimited or limited. After completing one of two questionnaires, which induced the belief that willpower is either unlimited or limited, participants then completed one of three tasks. The tasks consisted of a non-ego depleting self-control task, an ego-depleting self-control task, and a task shown to induce boredom, with the nondepleting and depleting conditions having been replicated from research by Job, Dweck, and Walton (2010). In the non-depleting condition, participants completed a task that involved crossing out all occasions of the letter “e” found on two pages …

Predictors Of Bullying In An Adolescent School Sample, Schell Hufstetler

Electronic Theses and Dissertations

Author's abstract: Bullying is a pervasive problem in our society. Contributing to this problem is the fact that bullying is not well understood. This makes it difficult to design successful interventions. The current study aims to create a complete picture of bullying in order to increase understanding of this behavior. For this study, 59 adolescents completed a survey packet including measures of bullying behaviors and other variables expected to relate to bullying. The results revealed that bullying is a problem for both genders. Multivariate analyses revealed males to be more directly and indirectly aggressive, but there were no significant gender …

"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham

Electronic Theses and Dissertations

Author's abstract: Some researchers assert that cultural display rules may explain differences in perceiving emotions (Matsumoto, Yoo, & Chung, 2010). The current study examined the display rule of masking within the Southern culture of honor. It was hypothesized that masking within the culture of honor negatively affects emotion perception sensitivity, particularly in the speed and accuracy of recognizing anger. Southern undergraduate students were primed with the culture of honor and then presented with the Emotional Expression Multimorph Task. Participants chose one of the six emotions (i.e., sad, happy, surprise, fear, disgust, or anger). It was hypothesized participants in the masking …
