Let's Get Physical: The Role Of Physical Activity In The Training Of Graduate Mental Health Students, Cassandra Pasquariello

Theses and Dissertations

There is growing awareness of the role of physical activity (PA) in the prevention and treatment of health disorders. Mental health practitioners are well positioned to provide PA counseling and may have ethical obligations to address PA. Researchers have cited insufficient training as a barrier to PA counseling, yet little is known about training in mental health. This exploratory study examines the need for training students in PA counseling. A national sample of 361 current graduate students in psychology, social work, rehabilitation counseling, and psychiatric nursing completed a Web-based survey on their training, knowledge, attitude towards PA, personal PA, and …

Pre- And Post-Migration Attitudes Among Ghanaian International Students Living In The United States: A Study Of Acculturation And Psychological Well-Being, Nicole Fischer

Theses and Dissertations

This qualitative study investigated attitudes among international students prior to their departure and following their arrival in the United States through a phenomenological research approach. Eight participants completed individual interviews in Accra, Ghana, and four participants completed follow-up email correspondence. The purpose of the study was to explain pre-migration expectations, post-migration experiences, and compare similarities and differences between perceptions and actual encounters. The researcher investigated five principle components of pre-migration: satisfaction with life prior to departure from the country of origin, impressions and expectations of the host country and predominate influences, awareness of discrimination in the host country, and culture-specific …

Adjustment Of Families With Children Adopted From Eastern Europe, Maria Kuznetsova

Theses and Dissertations

The purpose of this study was to examine the adjustment of older children and adolescents adopted from Eastern Europe and the impact of their preadoption history and family’s functioning on their adjustment. This is a follow-up study of families first surveyed in 2005 with an addition of new families. One hundred and forty-five families reporting on 194 adopted children (9 to 19 years; 104 girls) participated in this study at Time 2. The project was conducted as an internet-based survey. Parents and adopted children reported on children’s emotional, behavioral and social problems (CBCL and YSR), as well as family environment …

Minority Disproportionality In New Jersey, Shannon Kemp

Theses and Dissertations

This study sought to examine whether New Jersey districts exhibited minority disproportionality, or the overrepresentation of minority students in special education eligibility categories and placements. A dataset with a random sample of 200 school districts was compiled with special education data from the New Jersey Department of Education. Through analyses of four ethnicities, White, Black, Hispanic, and Asian, it was discovered that Black and Hispanic students were significantly more likely to be placed in special education as compared to their peers. Asian students were significantly less likely to be represented in special education in comparison to their non-Asian counterparts. Black …

Neuroendocrine Function Of Female Youth With Callous-Unemotional Traits, Andrew Gostisha

LSU New Orleans Theses and Dissertations

Callous-unemotional (CU) traits have been shown to designate a particular subgroup of antisocial youth that are particularly violent, recidivistic, and more likely to continue offending in adulthood. Disordered neuroendocrine function may be a mechanism for the development of CU traits. We examined whether altered stress responsivity served as a mechanism linking stress exposure and the expression of CU traits. Participants were 15 incarcerated adolescent girls with CU traits. Measures of CU traits, stress exposure, and salivary cortisol were collected. Results revealed girls with CU traits had higher morning levels of cortisol, an intact cortisol awakening response (CAR), and flatter diurnal …

Multinational Teams: The Relationship Between Work Values And Productivity And The Moderating Effect Of Degree Of Operational Integration, Kelly C. Kinnebrew

Electronic Theses and Dissertations

The present study gathered data from 147 employees in two U.S. headquartered multinational manufacturing companies. Participants responded to questions about their work-related values, perceptions of the productivity of their work teams, and the degree of operational integration between firms‟ foreign affiliate offices and their U.S. based headquarters. Additionally, analyses were conducted to assess the relationship between team productivity and psychic distance, which is a measure of country-level cultural differences. Work values were assessed using The Values Scale (Neville & Super, 1989), perceptions of team productivity were assessed used an instrument by Kirkman and Rosen (1999), degree of operational integration was …

Comprehension Of Functional Support By Enculturated Chimpanzees Pan Troglodytes, Anna M. Yocom, Sarah T. Boysen

Sentience Collection

Studies of causal understanding of tool relationships in captive chimpanzees have yielded disparate findings, particularly those reported by Povinelli & colleagues (2000) for tool tasks by laboratory chimpanzees. The present set of experiments tested nine enculturated chimpanzees on three versions of a support task, as described by Povinelli (2000), during which food rewards were presented in different experimental configurations. In Experiment 1, stimulus pairs included a choice between a cloth with a reward on the upper right corner or with a second reward off the cloth, adjacent to a corner, with the second pair comprised of a cloth with food …

Citalopram Improves Metabolic Risk Factors Among High Hostile Adults: Results Of A Placebo-Controlled Intervention., Thomas W. Karmarck, Matthew F. Muldoon, Stephen B. Manuck, Roger F. Haskett, Jeewon Cheong, Janine D. Flory, Elizabeth Vella

Faculty Publications

Hostility is associated with a number of metabolic risk factors for cardiovascular disease, including waist—hip ratio, glucose, and triglycerides. Along with hostility, many of these measures have also been shown to be associated with reduced central serotonergic function. We have previously reported that a citalopram intervention was successful in reducing hostility by self-report assessment (Kamarck et al., 2009). Here we examine the effects of this serotonergic intervention on metabolic risk factors in the same sample.

Perceptual Scale Expansion: An Efficient Angular Coding Strategy For Locomotor Space, Frank H. Durgin, Z. Li

Psychology Faculty Works

Whereas most sensory information is coded on a logarithmic scale, linear expansion of a limited range may provide a more efficient coding for the angular variables important to precise motor control. In four experiments, we show that the perceived declination of gaze, like the perceived orientation of surfaces, is coded on a distorted scale. The distortion seems to arise from a nearly linear expansion of the angular range close to horizontal/straight ahead and is evident in explicit verbal and nonverbal measures (Experiments 1 and 2), as well as in implicit measures of perceived gaze direction (Experiment 4). The theory is …

Moral Cognition In Children An Examination Of The Possible Impact Of School Didactic Philosophies, Smit S. Shah

HIM 1990-2015

The purpose of this thesis is to examine the effects that Montessori and public school environments have on the moral cognition of children and to assess the differences using modified moral dilemma stories. Through the analysis of these children's responses on moral dilemma stories this thesis reveals that there are stark and statistically significant differences in the children's responses on two of the three stories. The Montessori children scored higher on the morality level and the answers reflected altruism over authority on story one and story three. Through these results the researcher surmised that school environment can have an impact …

Cognitive Processes For Infering Tonic, Steven J. Kaup

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

Research concerning cognitive processes for tonic inference is diverse involving approaches from several different perspectives. Outwardly, the ability to infer tonic seems fundamentally simple; yet it cannot be attributed to any single cognitive process, but is multi-faceted, engaging complex elements of the brain. This study will examine past research concerning tonic inference in light of current findings. First I will survey the recent history of experimental research in cognitive functions for memory retention and expectation as they relate to the recognition and learning of musical schemas. Then I will discuss distributional theories associated with the tonal hierarchy of major and …

Testing Mediated Effects Of A Sex Education Program On Youth Sexual Activity, Paul James Birch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Empirical investigations have identified hundreds of factors that predict whether youth engage in sexual activity (YSA). To promote optimal health and the avoidance of unhealthy or problematic outcomes that can result from YSA, sex education programs have been extensively developed and evaluated. Many evaluations have identified the effect of the program on immediate outcomes such as attitudes and intentions, others have examined subsequent behavioral and health outcomes, and some have done both. The purpose of this study was to extend the evaluation literature by testing a mediated effects model. A sex education program was found to have significant immediate effects …

Examining The Experience Of Recent War Veterans Who Report Posttraumatic Stress Disorder, Neda C. Raymond

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder (PTSD), an anxiety disorder that develops following exposure to a traumatic event, has long been associated with military combat. Despite the well-documented negative effects of PTSD, careful, in-depth accounts of the experience of those suffering from PTSD are rare. The present study employed Descriptive Experience Sampling (DES) to explore the inner experience of seven Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) veterans with combat-related PTSD. Potential participants completed the PTSD Checklist - Military Version to determine the presence and severity of PTSD symptomatology. Participants who reported significant symptoms of combat-related PTSD participated in DES. A …

A Moderational Model Investigating Child Temperament, Executive Functioning, And Contextual Predictors Of Externalizing Behaviors In Preschoolers, Ferne Arlene Pinard

Dissertations

Child externalizing behavioral problems (e.g., ADHD symptoms and aggressive behaviors) often appear early in life, are relatively stable, and are associated with maladaptive outcomes in many domains of functioning. Research has shown that, for a subset of children who demonstrate these early behavioral patterns, the course is often more pervasive and persistent. Consequently, a better understanding of externalizing behavioral problems during the preschool period is essential. The current study examined whether biologically-based correlates (i.e., child temperament and executive functioning/neurocognitive attention; EF/Attention) would moderate the relation between the contextual correlates (i.e., socioeconomic status and parenting practices) and externalizing behaviors (i.e., ADHD …

Imagery And Contamination Aversion, Thomas Grover Adams

Graduate Theses and Dissertations

Contamination-based obsessive-compulsive disorder (OCD) is the most common form of OCD. Recent research indicates that the emotion of disgust may play a primary role in the etiology and maintenance in contamination-based OCD (CB-OCD). However, little is known about the effects of disgust on compulsive behaviors related to CB-OCD (e.g.,, hand-washing). The present study utilized an imagery-priming paradigm to test the effects of experienced disgust on compulsive hand-washing. Seventy-eight participants were selected for high or low symptoms of CB-OCD. Following response training, participants were submitted to a disgust or neutral imagery task. Following the imagery task, participants rated their subjective fear …

The Relation Between Externalizing Behaviors Of Children With An Autism Spectrum Disorder And The Externalizing Behaviors, Internalizing Symptoms, And Social Problems Of Their Typically-Developing Siblings, Theodore S. Tomeny

Master's Theses

Existing literature regarding the maladjustment of siblings of children with an autism spectrum disorder (ASD) remains inconclusive. Some studies suggest that difficulties associated with having a child with an ASD in the family result in an adverse experience for both parents and siblings. Dissent within. the literature suggests that certain factors, both environmental and genetic, must be present for maladjustment to occur in typically-developing siblings. Parents of a child with an ASD and a typicallydeveloping sibling (ASD group) and parents of two typically-developing siblings (Control group) provided data via online questionnaires. Both diagnostic category and autism symptoms severity were tested …

The Relationship Of Testosterone And 5-Ht To Aggressive, Self-Aggressive, And Antisocial Behavior In Men, Anne Winston Mcintyre

Master's Theses

Studies of humans show an inconsistent relationship between aggression and T, as well as between T and antisocial and self-aggressive behavior. Other biological variables, including cortisol and brain serotonin, have been implicated as having an effect on the regulation of antisocial and self-aggressive behavior. Researchers have suggested that inconsistencies in the T-aggression relation may be due to the presence of moderating variables. One theory posits that serotonin moderates the relation between T and aggression. The purpose of this study was to examine the relationship between T (as well as cortisol and 5-HT) and aggression-related constructs. A second purpose was to …

Galantamine-Induced Tremulous Jaw Movements In Rats: Reversal With Adenosine A2a Antagonists, Chelsea Elizabeth Leser

Honors Scholar Theses

Alzheimer's disease is the most common neurdegenerative disorder, affecting millions of people worldwide. The underlying etiology of Alzheimer's disease, however, is such that treatment is difficult.

Researchers have linked a decrease in the transmission of the neurotransmitter acetylcholine to the cognitive deficits seen in Alzheimer's disease. Recent drug therapies have focused on using drugs that block the action of the enzyme, acetylcholinesterase, that breaks down acetylcholine. However, these drugs, known as acetylcholinesterase inhibitors, have been found to produce side effects that have the same characteristics as Parkinson's disease, the second most common neurodegenerative disorder. In this study, the acetylcholinesterase inhibitor, …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury

Dissertations

Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …

Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms

Master's Theses

Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …

Does Physical Activity Influence Semantic Memory Activation In Amnestic Mild Cognitive Impairment?, J. Carson Smith, Kristy A. Nielson, John L. Woodard, Michael Seidenberg, Matthew D. Verber, Sally Durgerian, Piero Antuono, Alissa M. Butts, Nathan C. Hantke, Melissa A. Lancaster, Stephen M. Rao

Psychology Faculty Research and Publications

The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03), suggesting PA may enhance memory-related caudate activation in aMCI.

The Levels Of Analysis Revisited., Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The term levels of analysis has been used in several ways: to distinguish between ultimate and proximate levels, to categorize different kinds of research questions and to differentiate levels of reductionism. Because questions regarding ultimate function and proximate mechanisms are logically distinct, I suggest that distinguishing between these two levels is the best use of the term. Integrating across levels in research has potential risks, but many benefits. Consideration at one level can help generate novel hypotheses at the other, define categories of behaviour and set criteria that must be addressed. Taking an adaptationist stance thus strengthens research on proximate …

Suicide Risk At Young Adulthood: Continuities And Discontinuities From Adolescence, Carole Hooven, Karen A. Snedker, Elaine Adams Thompson

Sociology Faculty Articles and Research

Young adult suicide is an important social problem, yet little is known about how risk for young adult suicide develops from earlier life stages. In this study the authors report on 759 young adults who were potential high school dropouts as youth. At both adolescence and young adulthood, measures of suicide risk status and related suicide risk factors are collected. With a two-by-two classification on the basis of suicide risk status at both adolescence and young adulthood, the authors distinguish four mutually exclusive groups reflecting suicide risk at two life stages. Using ANOVA and logistic regression, both adolescent and young …

Resolving Incidents Of Bullying Among High Functioning Adolescents With Asd: Parent Perspectives, Wan-Ting Chuang

Theses and Dissertations

A qualitative study was conducted investigating the perceptions of seven parents of high functioning adolescents with autism spectrum disorders (ASD) regarding incidents of bullying in which the child was involved. Results of the study indicated that all of the children had been bullied at one time or another, and that the majority had difficulty in demonstrating appropriate social skills. The parents viewed supportive peers to be a positive factor, fostering the children's satisfactory social adjustment. Parent interventions for their child included social skills instruction and empathy training. Research implications for educators included the need to establish systemic organized school-wide support …

Antecedents And Continuity Of Compliance In Preschoolers, Lauren Gindin

Master's Theses

Self-regulation, and compliance behavior specifically, has been implicated in the development of successful socialization. Difficulty self-regulating has led to negative outcomes in areas such as academic success and mental health, and a number of possible contributors, such as temperament, maternal sensitivity and attachment, have been identified. In this study, we examined these possible predictors of preschool compliance behavior through causal modeling utilizing a large and diverse longitudinal dataset from the NICHD Study of Early Child Care and Youth Development. We aimed to predict compliance and delay of gratification performance in children across 2, 3 and 4.5 years of age by …

The Effect Of Postpartum Depression On Child Cognitive Development, Joshua Lees

Theses and Dissertations

The incidence of postpartum depression (PPD) in Western societies is approximately 10-15% and its cause is multi-faceted. Because mothers largely constitute infants' social environment and mediate their experience of the external world, it is imperative to investigate the effects of PPD on child growth and development. Within this paper, the author explores previously conducted Post-Partum Depression research, in regards to its effects on child cognitive development. Following this literature review, a brief experimental study is conducted and explained on a sample population of mothers' of special needs children, serviced by an Early Intervention provider. During this experimental analysis, the researcher …

Interactive Software And Its Effects On Hostility, Warren Shya

Theses and Dissertations

The researcher will be exploring the relationship between violence in video games and the emotional responses to them. The goal of the study is to confirm the previous body of research that a short term increase in aggression and hostility exists after a violent video game is played. The study will also expand on the current existing body of data by examining other variables such as gender, age, typical time spent in a week playing videogames, overall familiarity with video games, the game genre that is normally played, and what consoles and systems are typically used to be played on. …

Rate Changes In Risky Behavior & The Role Of Sibling Influence, Julian Bajczyk

Theses and Dissertations

This study is based on research performed in 2006 by Laura Argys, Daniel Rees, Susan Averett, and Benjama Witoonchart. The 2006 study investigated relationship between the birth order and an adolescent's likelihood of engaging in certain risky behaviors. For the purpose of this study these behaviors include things like drug use, sexual activity and violent or antisocial offenses. The initial study found a trend implicating that adolescents with older siblings more likely to engage in certain risky behaviors than adolescents who did not have older siblings (eldest and only children). The Argys, et al. study used data collected from the …

The Professional Identity Development Of Gerontologists: An Experiential Learning Approach, Tracey Gendron

Theses and Dissertations

Professional identity is a complex construct that describes how an individual develops a sense of self-concept within a chosen profession. Professional identity refers to a self definition within a professional role based on attributes, beliefs, values, motives, and experiences (Ibarra, 1999). This study explored the relationships between the professional identity of gerontology graduates and age, career stage, student typology, occupation, and value of experiential learning both quantitatively and qualitatively. Survey results indicate that experiential learning opportunities provide a framework for all gerontology students to gain and apply the skills and knowledge necessary for professional identity development in the field of …
