Psychological Determinants Of Physical Activity And The Prediction Of Physical Activity Levels In African American Men, Alvin L. Morton Iii

Doctoral Dissertations

African American (AA) men experience disproportionally higher rates of non-communicable, chronic diseases (e.g., cardiovascular, type 2 diabetes, and renal failure) than White men. Physical activity (PA) is known to reduce the progression of CVD, type 2 diabetes, and renal failure. National statistics illustrate that AA men are less likely to get sufficient levels of PA to obtain health benefits. Although many factors (e.g., biomedical, socio-cultural) influence participation in PA, the psychological factors at the individual level are essential to beginning and maintaining activity. Therefore, understanding the psychological determinants of PA in AA men and their associations with meeting national guidelines …

An Examination Of Music Majors’ Exercise Motivations And Readiness For Change, Jason Ruggieri

Doctoral Dissertations

This dissertation examined hypothesized differences in college students’ exercise behaviors, motivations, and readiness for change. Previous research confirms longstanding health benefits of regular physical activity and corresponding wellbeing and mortality risks of a sedentary lifestyle. Despite this evidence, people become increasingly more inactive over time. Overall, college students perpetuate these life-long sedentariness trends. Music students encounter physical performance demands unique to degree programs, endorsing more physical and mental health complaints than most undergraduates. Self-determination theory and the transtheoretical model of behavior change postulate individuals with strong self-directed motivations and willingness to enact behavior changes are more likely to be physically …

Working Alliances: The Implications Of Person-Centered Theory For Student-Teacher Relationships And Learning, Adam Parker Cogbill

Doctoral Dissertations

In this dissertation project, I interview four therapists and four writing teachers to learn if there were any significant similarities in differences in their approaches to dyadic relationships with students and clients. By dyadic, I mean what happens between individuals in a 1-on-1 setting when subjectivities collide. I was guided in my investigation by the core concepts of person-centered theory, which have heavily influenced the work of clinical therapists for the past half-century or more. These concepts are congruence, or whether one’s behaviors and speech match what one is feeling; empathy, the process of entering and becoming familiar with another’s …

The Development And Validation Of An Automatic-Item Generation Measure Of Cognitive Ability, Scott Hines

Doctoral Dissertations

Cognitive ability is perhaps the most studied individual difference available to researchers, being measured quickly and effectively while demonstrating a predictable influence on many life outcomes. Historically, the evolution of the psychometric study of cognitive abilities has pivoted on the development of new and better methodologies allowing for a more complete and efficient capture of intellect. For instance, recent advances in computer and Internet technology have largely replaced traditional pencil-and-paper methods, allowing for innovative item development and presentation. However, concerns regarding the potential adverse impact and test security of online measures of cognitive ability, particularly in unproctored situations, are well …

Personal Intelligence And Learning About Personality In Everyday Life, Jayne L. Allen

Doctoral Dissertations

As we encounter other people, we form impressions of and judgments about them. Based on these evaluations, we choose whether we want to interact any further, and if we do, what type of relationship we want to have. Although such choices can have far-reaching consequences, we typically base them on tacit knowledge. Our abilities to reason about our own and others’ personalities—abilities theorized to be part of a personal intelligence (Mayer, 2008)—determine in part the relationship outcomes we experience.

The existence of such an intelligence implies that people have a “database” they consult when making personality-relevant decisions. This raises the …

The Mediating Influence Of Career Aspirations And Career Decision-Making Self-Efficacy On Self-Differentiation, Vocational Identity, And Career Indecision, Jay Justin Middleton

Doctoral Dissertations

Research indicates that numerous family variables influence the career-development process (Osipow, 1983). Bowen's family systems theory is one model through which to view the development and influence of the family on career development (Bowen, 1972). According to his theory, individuals begin life highly dependent on family members for all forms of support. As people grow into adults, they slowly become independent of their family, or self-differentiated. Adults low in self-differentiation have been found to make decisions in order to appease their families. Further, low levels of self-differentiation have been related to greater mental health problems (Skowron & Friedlander, 1998) and …

The Relationship Between Executive Functioning And Substance Abuse, John M. Tracy

Doctoral Dissertations

Substance use disorders are a widespread issue in society today with approximately 20 million people in the U.S. alone experiencing drug-related problems (Substance Abuse and Mental Health Services Administration, 2012). However, treatment is often ineffectual with approximately 50% of addicted individuals returning to substance use. One factor found to impact individuals' treatment response is their neuropsychological functioning. Drug-abusers frequently exhibit severe executive functioning impairments across a number of domains, and there is evidence that these deficits may be time and substance-dependent. Executive functions are mental processes critical in motivation, planning, and goal-directed behaviors. With extended abstinence, research suggests cognitive improvements …

Psychometric Properties Of Three Common Depression Measures In Breast Cancer Patients With Major Depressive Disorder, Audrey Ashton File

Doctoral Dissertations

Breast cancer is the most frequently diagnosed cancer among women in the United States and MDD is the most common mental health problem in women with breast cancer. There is lack of research on measures of depression in this population. This study examined the psychometric properties of three commonly used depression measures, the BDI-II, CES-D, and HRSD, with clinically depressed breast cancer patients (n = 127). Findings revealed the measures displayed good distributional characteristics, internal consistency, and convergent validity. Discriminative validity with the BAI was not demonstrated, however, and confirmatory factor analyses indicated that the existing models of these …

Personal Factors, Domain Specificity, And Risky Decision-Making, Rose Niles

Doctoral Dissertations

Adults make many risky decisions daily, such as choosing to drive over the speed limit or going outside without previously applying sunscreen. How and why adults make such decisions remains relatively unknown and has gained much research attention. Traditional models of decision-making, such as Expected Utility Theory (Bernoulli, 1954) and Prospect Theory (Kahneman & Tversky, 1972) have proven too simplistic, as they do not account for the regular deviations from expected decision-making processes. Likewise, models that attempt to categorize individuals as risk seeking and risk-averse do not hold up well when decisional-domain is examined (Blais & Weber, 2006). Contemporary research …

Factors Predicting Weight Loss And Weight Gain In Bariatric Surgery Patients, Deborah Potisek Simpson

Doctoral Dissertations

Obesity has become an epidemic in the United States that can result in problems in multiple areas of an individual's life. Bariatric surgery has been shown to be an effective weight loss treatment for obese and morbidly obese individuals; however, although many individuals obtain long-term weight loss success after surgery, there is a percentage of patients who do not obtain the expected weight loss or end up regaining the weight they had initially lost. In an attempt to identify those who may be at risk for poorer results after bariatric surgery, most surgeons require that an individual undergo a psychological …

Ptsd, Academic Achievement, And College Persistence: The Moderating Effects Of Coping Mechanisms And Social Support, Rebecca Granda

Doctoral Dissertations

Prevalence rates of lifetime exposure to trauma for college students range from 50 to 90% indicating that most college students begin the first year of college with a history of trauma. Previous studies suggest a significant negative relationship between posttraumatic stress disorder (PTSD) and college retention; however, these studies have mainly focused on the negative effects of trauma exposure and PTSD on college students' persistence. As a result, it was unknown whether the effects of PTSD on academic achievement and college persistence can be moderated by protective factors, such as coping skills and social support. The purpose of this study …

Chronotype Preference, Partial Sleep Deprivation, And Executive Functions Performance Throughout The Wake-Cycle, Devin Layne Merritt

Doctoral Dissertations

Sleep is vital to survival and well-being. Adequate sleep, which is conceptualized in terms of quantity and quality, is positively related to a number of cognitive functions. In terms of length, it has been recommended that individuals in late adolescence and adulthood should receive no less than eight hours of sleep. Negative effects on higher-order mental processes have been found in states of sleep deprivation. Individuals who experience total sleep deprivation show decrements in performance on tasks of executive function (i.e. sustained attention, planning, and decision making). However, the effects of partial sleep deprivation on executive functions has not been …

The Effects Of Encouraging Student-Faculty Interaction On Academic Success, Identity Development, And Student Retention In The First Year Of College, Katerina Karaivanova

Doctoral Dissertations

The study presented in this dissertation was designed to investigate the effects of a brief intervention encouraging student-faculty interaction among college students on their academic achievement, college adjustment and intent to withdraw. Additionally, the effects of identity style on academic achievement, college adjustment, and student-faculty interaction were examined. Two hundred and five first year students participated in a four-part study, measuring the frequency and quality of student-faculty interaction, college adjustment, and identity development at three different time points. Students were randomly assigned to one of three experimental groups; only one group received the advice to meet with faculty outside of …

Reasons For Revealing And Concealing Interpersonal Trauma, Sidney Bennett

Doctoral Dissertations

Prior research has documented the role that revealing and concealing interpersonal violence has on health outcomes for victims (e.g., Ullman, 2010). The present paper aims to add to the existing research by presenting a new model, The Revealing and Concealing Process Model for Interpersonal Trauma, to describe the process that occurs when victims reveal or conceal interpersonal violence. The second stage of the model (i.e., reasons for revealing/concealing interpersonal violence) was tested by: 1. Creating a measure to assess the reasons for revealing and concealing interpersonal violence and 2. Identifying whether getting goals met for revealing/concealing is related to health …

Using Your Mind To Train Your Body: An Experimental Autobiographical Memory Intervention For Adolescent Physical Activity, Mathew Biondolillo

Doctoral Dissertations

Developmentally, physical activity levels tend to decline from adolescence to early adulthood. Adolescent physical activity programs have been largely ineffective, leading to a call for new low-cost interventions. This study examined the effects of an autobiographical memory intervention on adolescent physical activity. Over six weeks, students (N = 558) in a New England middle school completed questionnaires and were timed weekly in physical education classes while training for a school-wide race. During Week Three, some students were asked to provide a positive motivational physical activity memory and others a control memory. Students indicated their intentions to be physical active, completed …

What Is Self-Potential And How Does It Relate To Personal Intelligence?, Bonnie Ann Barlow

Doctoral Dissertations

Intelligence is an important ability that we use in our everyday lives to understand people, such as choosing the best partner to work with on a project. Personal intelligence is the ability to “reason about personality and its processes, as applied to one’s self and others” (Mayer, Panter & Caruso, 2012). The Test of Personal Intelligence (TOPI) was developed to test this important ability. If the TOPI measures people’s ability to understand their own and other’s personality, as personal intelligence increases so should a person’s level of self-potential. This idea was tested in two studies by conducting correlations between the …

May I Help You? How Stereotypes And Innuendoes Influence Service Encounters, Lauren Michelle Brewer

Doctoral Dissertations

"You only get one chance to make a good first impression." The dissertation focuses on marketing agents; among the most visible is the "service provider." Previous research establishes the important role of cognitive social schemata in determining the way consumers react to different types of marketing agents, including service providers. In the literature review, a classification schema is developed for service provider stereotypes derived from theory using social stereotypes. The development of the Service Provider Perception Framework (SPPF) creates a classification for the individual service provider along two main dimensions: competence and affect.

In services design (particularly situations involving a …

The Relationship Of Personality To Entrepreneurial Performance: An Examination Of Openness To Experience Facets, Adam R. Smith

Doctoral Dissertations

The role of personality has resurfaced in entrepreneurship research. The results surrounding the broad personality traits have varied. Although openness to experience has been found to generally have a positive relationship with entrepreneurial intentions and performance (e.g., Zhao, Seibert, & Lumpkin, 2010), conflicting and inconsistent results have emerged (e.g., Baron & Markman, 2004; Ciaverella, Buchholtz, Riordan, Gatewood, & Stokes, 2004). Therefore, an in-depth look at the facets of openness to experience may offer additional information.

The present investigation used a sample of founder/owners and examined the facets of openness to: fantasy, aesthetics, feelings, actions, ideas, and values. Specifically, it was …

Examining Social Climate And Youth Social Goals On Extended Wilderness Courses: A Path Toward Improving Participant Experiences, Benjamin J. Mirkin

Doctoral Dissertations

This dissertation examined participants' expectations of the social climate on extended wilderness courses, how students' actually experienced the social climate during their course, and how these expectations, perceptions and the influence of environmental characteristics, impacted their goals for peer interactions. Pre and posttest surveys were used to assess students' expectations and perceptions of their experience and multi level modeling was used to better understand the relationship of social climate to peer interaction. The research was undertaken to improve the practical and theoretical understanding of organizations' and leaders' ability to facilitate a social climate that promotes adaptive forms of social motivation. …

Movements, Dive Behavior And Trophic Ecology Of Leatherback Turtles (Dermochelys Coriacea) In The Northwest Atlantic, Kara Dodge

Doctoral Dissertations

The endangered leatherback turtle is a highly migratory predator that feeds exclusively on gelatinous zooplankton. Leatherbacks spend most of their lives submerged or offshore, and their at-sea biology (particularly that of males and sub-adults) is poorly understood throughout much of their range. I used satellite telemetry to monitor movements and dive behavior of nine adult and eleven sub-adult leatherbacks captured off Massachusetts, USA, and tracked throughout the NW Atlantic. Leatherback movements and environmental associations varied by oceanographic region, with slow, sinuous, area-restricted search behavior and shorter, shallower dives occurring in cool, productive, shallow shelf habitat at temperate latitudes. Leatherbacks were …

Violent Socialization Processes And Criminal Behavior: An International Perspective On Variations In Social Control During Late Adolescence And Emerging Adulthood, Aimee Delaney Lutz

Doctoral Dissertations

Using Gottfredson and Hirschi's parental socialization thesis as a theoretical framework, the present study explores whether or not violent socialization processes are associated with criminal behavior, both at the micro-level and macro-level, across 32 different nations. Analyses were conducted on data from the International Dating Violence Study (Straus & Members of the International Dating Violence Research Consortium, 2004). Bivariate statistical analyses show that violent socialization tends to be more prevalent among nations with indicators of violence (e.g., laws supporting the death penalty) compared to nations without such indicators. The results of ordinary least squares regression analysis indicate that violent familial …

Racial Prejudice, Homophobia, And Sexism As A Function Of Right-Wing Authoritarianism, Religious Values, Religious Pressures, And Religious Orientation, Dixie Turner

Doctoral Dissertations

Past literature is ambiguous regarding relationships among different religious variables and prejudice. The purpose of this study was to clarify complicated relationships among religious pressures, religious fundamentalism, Christian orthodoxy, intrinsic and extrinsic religious orientation, quest orientation, right-wing authoritarianism, and the outcome variables of racial prejudice, homophobia, and sexism. Two models, a developmental model and social learning model, were proposed in this study and were tested using structural-equation modeling. Participants were 310 self-identified Christian students. Several predicted paths were deleted in both models because they did not contribute to good fit. Three predictor variables: Christian orthodoxy, extrinsic religious orientation, and religious …

“It Can Start From Anything”: An Existential Phenomenological Investigation Of Athletes’ Experiences Of Psychological Momentum, Greg Young

Doctoral Dissertations

Psychological Momentum (PM) is a commonly recognized phenomenon in sport, yet remains one of the least understood (Taylor & Demick, 1994). Previous research examined PM using archival data (Gayton & Very, 1993; Gilovich, Vallone, & Tversky, 1985; Koehler & Conley, 2003; Silva, Hardy, & Crace, 1988), hypothetical and contrived scenarios (Eisler & Spink, 1998; Miller & Weinberg, 1991; Perreault, Vallerand, Montgomery, & Provencher, 1998; Vallerand, Colavecchio, & Pelletier, 1988), and actual performance (Mack, et al., 2008). More recently, Jones and Harwood (2008) used semi-structured interviews to examine participants’ …

"I Remember When You Taught Me That!" Developmental And Gender Differences In Children's Episodic Memories Of Learning Events During The Early School Years, Rhyannon H. Bemis

Doctoral Dissertations

The study presented in this dissertation was designed to investigate young children's ability to accurately recall episodic (i.e., specific-one-moment-in-time) memories of learning events and whether this ability was related to another metacognitive skill, source monitoring. Further, the study investigated possible gender differences in the ability to recall learning events. Sixty children, ages four to six years, participated in two staged learning events about two novel topics, the Aleutian Islands and the visual system. Following a delay, children were interviewed and asked both general factual knowledge questions and questions about the target material learned in the staged events. Children were asked …

Three Elements Of Self-Regulated Learning: Metacognitive Functioning, Self-Efficacy, And Study Behavior, Catherine E. Overson

Doctoral Dissertations

Individuals' metacognitive insight regarding their own performances -- what people think they know about what they know -- is often flawed. Students' metacognitive functioning was examined in two studies. In Study 1, exam performance estimates compared with actual scores were assessed across three in-class exams. Results demonstrated a systematic tendency for lower performers to overestimate their exam performances. Top performers underestimated their performance. In Study 2, an incentive to be as accurate as possible in exam performance estimations ($50 gift card) did not reduce estimation miscalculations for either bottom or top performers.

In Study 1, higher levels of students' self-efficacy …

The Effect Of Culture And Self-Construal On Memory Development: Mother-Child Conversations In Eastern Turkey, Western Turkey And The United States, Basak Sahin

Doctoral Dissertations

Eighty-seven mothers and their four-year-old children from Eastern Turkey (N = 32 mother-child pairs), Western Turkey (N =30 mother child pairs) and the United States (N = 25 mother-child pairs) participated in a study of mother-child memory talk, self-construal and parenting goals. Mother-child pairs were audio-recorded while drawing pictures and talking about shared past and anticipated future events. Mothers completed Balanced Integration-Differentiation questionnaires and were scored as high or low on individuation and relatedness orientations. They completed child rearing goals questionnaires that were scored for conformity, self-maximization and power factors. Memory and future talk differed across culture and self-construal groups. …

An Exploration Of The Relationship Among Online Social Network Usage, Intimacy, Social Comparison Tendencies, And Relationship Satisfaction, Matthew Hand

Doctoral Dissertations

The popularity of online social networks prompts an examination of the effects these websites have on intimate relationships. While these networks have received a considerable amount of attention in mainstream media, peer-reviewed research examining the effects these websites have on users is sparse. By their very nature, online social networks involve the creation and maintenance of interpersonal relationships. As such, the effect of these networks on relationships may be profound and with the paucity of research on the topic, the relationship between online social networks and interpersonal relationships is an important area of study. The present study sought to examine …

Selected Demographic Characteristics And Social Interest As Predictors Of Teacher Stress, Barry J. Morales

Doctoral Dissertations

The purpose of the research was to study stress in teachers in Louisiana by utilizing a descriptive/comparative research design. Hypotheses were tested concerning relationships between each of seven independent variables and the dependent variable (teacher stress). The independent variables were (a) years of teaching experience, (b) educational levels of teachers (college degrees), (c) age, (d) gender, (e) social interest, (f) geographical location (North and South Louisiana), and (g) educational levels of students taught by teachers (elementary, middle, high school). The procedure for choosing the participants involved a sample of convenience whereby superintendents provided access/permission to specific schools. Nine schools (three …

The Reminiscence Bump In Autobiographical Memory: An Investigation Of The Life Script Hypothesis, Ryan Alexander Dickson

Doctoral Dissertations

Researchers have consistently found that older adults report a higher percentage of autobiographical memories for experiences that occurred between ages 15 and 30 compared to any other period of life. This reminiscence bump is evident for memories involving positive emotions but not for memories involving negative emotions. The life script hypothesis proposes that people share cultural knowledge for the types and timing of positive landmark events expected to occur over the life course and that this shared knowledge guides the retrieval of autobiographical memories. In a series of five studies, the valence (positive and negative) and expectedness (not surprising and …

Sophisticated Credulity: Are Old Beliefs Disguised By New Terminology And Selective Learning?, Matthew A. Ramsey

Doctoral Dissertations

The present research attempted to distinguish between traditional anomalistic belief (TAP) and pseudoscientific anomalistic belief (PSAP). In Study 1, I constructed the PSAP scale and then, to establish construct validity, examined its correlation to other measures related to TAP. In Studies 2 and 3, I examined how high and low TAP and PSAP believers differed in recalling information that either did, or did not support the existence of anomalistic phenomena. Participants read 12 abstracts on paranormal phenomena and were given T/F recall questions either immediately (Study 2) or following a four day delay period (Study 3). As expected, high and …
