Possible Psychosocial Benefits Of Having A Sibling With A Disability, Jenna M. Talbott

Senior Honors Theses

Possible psychosocial benefits resulting from exposure to siblings with disabilities are investigated in the current study. Previous literature has generally overlooked the possibility of psychosocial benefits by exclusively focusing on the negative effects of having a sibling with disabilities. Contact theory suggests that the increased exposure to individuals with disabilities should increase positive attitude toward those who are struggling with disadvantages. This investigation hypothesized that this tendency would be manifested as elevated empathy and compassion in individuals who have siblings with disabilities, and that these traits would be influenced by certain demographic variables. A survey was distributed, and the responses …

Changes In Sleep Time And Sleep Quality Across The Ovulatory Cycle As A Function Of Fertility And Partner Attractiveness, Brooke N. Jenkins, Elizabeth G. Pillsworth, Aaron T. Goetz

Psychology Faculty Articles and Research

Research suggests that near ovulation women tend to consume fewer calories and engage in more physical activity; they are judged to be more attractive, express greater preferences for masculine and symmetrical men, and experience increases in sexual desire for men other than their primary partners. Some of these cycle phase shifts are moderated by partner attractiveness and interpreted as strategic responses to women’s current reproductive context. The present study investigated changes in sleep across the ovulatory cycle, based on the hypothesis that changes in sleep may reflect ancestral strategic shifts of time and energy toward reproductive activities. Participants completed a …

Comparison Of Functional Network Connectivity For Passive-Listening And Active-Response Narrative Comprehension In Adolescents, Yingying Wang, Scott K. Holland

Center for Brain, Biology, and Behavior: Faculty Publications

Comprehension of narrative stories plays an important role in the development of language skills. In this study, we compared brain activity elicited by a passive-listening version and an active-response (AR) version of a narrative comprehension task by using independent component (IC) analysis on functional magnetic resonance imaging data from 21 adolescents (ages 14–18 years). Furthermore, we explored differences in functional network connectivity engaged by two versions of the task and investigated the relationship between the online response time and the strength of connectivity between each pair of ICs. Despite similar brain region involvements in auditory, temporoparietal, and frontoparietal language networks …

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

Linking Brain Electrical Signals Elicited By Current Outcomes With Future Risk Decision-Making, Dandan Zhang, Ruolei Gu, Lucas S. Broster, Yang Jiang, Wenbo Luo, Jian Zhang, Yue-Jia Luo

Behavioral Science Faculty Publications

The experience of current outcomes influences future decisions in various ways. The neural mechanism of this phenomenon may help to clarify the determinants of decision-making. In this study, thirty-nine young adults finished a risky gambling task by choosing between a high- and a low-risk option in each trial during electroencephalographic data collection. We found that risk-taking strategies significantly modulated mean amplitudes of the event-related potential (ERP) component P3, particularly at the central scalp. The event-related spectral perturbation and the inter-trial coherence measurements of the independent component analysis (ICA) data indicated that the “stay” vs. “switch” electrophysiological difference associated with subsequent …

Using Otoacoustic Emissions To Evaluate Efferent Auditory Function In Humans, Simon Henin

Dissertations, Theses, and Capstone Projects

The auditory system continually adapts to changes in the acoustic environment over short periods of time. This fine-tuning of its dynamics is mediated in part by the medial olivocochlear (MOC) bundle, a neural feedback loop which aids in the regulation of cochlear micro-mechanics. The ability to measure the response of the MOC system in humans may provide significant insight into unique cochlear functions, such as its sharp frequency selectivity and wide dynamic range. In humans the efferent system can be investigated non-invasively using otoacoustic emissions (OAEs). However, how OAEs can best be used to evaluate efferent function, the pitfalls associated …

Meta-Analysis Of Social-Personality Psychological Research, Blair T. Johnson, Alice H. Eagly

CHIP Documents

This publication provides a contemporary treatment of the subject of meta-analysis in relation to social-personality psychology. Meta-analysis literally refers to the statistical pooling of the results of independent studies on a given subject, although in practice it refers as well to other steps of research synthesis, including defining the question under investigation, gathering all available research reports, coding of information about the studies and their effects, and interpretation/dissemination of results. Discussed as well are the hallmarks of high-quality meta-analyses.

Can Helmet Design Reduce The Risk Of Concussion In Football?, Steven Rowson, Stefan M. Duma, Richard M. Greenwald, Jonathan Beckwith, Jeffrey J. Chu, Kevin M. Guskiewicz, Jason P. Mihalik, Joe Crisco, Bethany J. Wilcox, Thomas W. Mcallister, Arthur C. Maerlender, Steven P. Broglio, Brock Schnebel, Scott Anderson, P. Gunnar Brolinson

Center for Brain, Biology, and Behavior: Faculty Publications

Of all sports, football accounts for the highest incidence of concussion in the US due to the large number of athletes participating and the nature of the sport. While there is general agreement that concussion incidence can be reduced through rule changes and teaching proper tackling technique, there remains debate as to whether helmet design may also reduce the incidence of concussion. A retrospective analysis was performed of head impact data collected from 1833 collegiate football players who were instrumented with helmet-mounted accelerometer arrays for games and practices. Data were collected between 2005 and 2010 from 8 collegiate football teams: …

Winning And Losing: Differences In Reward And Punishment Sensitivity Between Smokers And Nonsmokers, Laura E. Martin, Lisa S. Cox, William M. Brooks, Cary R. Savage

Center for Brain, Biology, and Behavior: Faculty Publications

Background: Smokers show increased brain activation in reward processing regions in response to smoking-related cues, yet few studies have examined secondary rewards not associated with smoking (i.e., money). Inconsistencies exist in the studies that do examine secondary rewards with some studies showing increased brain activation in reward processing brain regions, while others show decreased activation or no difference in activation between smokers and nonsmokers. Aims: The goal of the current study is to see if smokers process the evaluation and delivery of equally salient real world rewards similarly or differently than nonsmokers. Methods: The current study employed functional magnetic resonance …

Hispanic Construction Workers And Assertiveness Training, Pramen Shrestha, Nancy Menzel

Nursing Faculty Research

BACKGROUND: Hispanic (Latino) construction workers experience disparities in occupational death and injury rates in the United States. The cultural value of respect for those in authority may hinder these workers from requesting safe working conditions from supervisors.

OBJECTIVE: To evaluate whether Hispanic construction workers in Las Vegas, Nevada found assertiveness training more useful than non-Hispanic trainees and whether or not they practiced this behavior at work after the training.

METHODS: An assertiveness training simulation was part of fall prevention classes offered to area construction workers. Eight weeks after the training, participants were interviewed by telephone about class topics they found …

Knowledge, Attitude, Lifestyle Practices, And Quality Of Life In Sporadic Lymphangioleiomyomatosis Patients, Shahpar Vafamand

Walden Dissertations and Doctoral Studies

Lymphangioleiomyomatosis (LAM) is a rare lung disease recognized by abnormal growth of smooth muscle cells proliferating in lungs parenchyma, developing benign tumors, migrating to the other organs, and ultimately leading to respiratory failure and death. Despite existing literature mainly on clinical aspects of LAM, there is a gap of literature in regards to the knowledge, attitude, and lifestyle practices (KAPs) of LAM patients and their effects on their quality of life. The purpose of this quantitative study was to investigate the KAPs of the sporadic LAM patients as measured by the Bristol Chronic Obstructive Pulmonary Disease Knowledge Questionnaire, Beliefs and …

Grounded Labels From The Behavioral International Economic Development Growth Path Model On Economic Development Patterns From 2002-2012, Kenneth Thomas Davis

Walden Dissertations and Doctoral Studies

Economic models generally fail to adequately measure positive and negative growth paths in development through agrarian, industry, and service economies. The purpose of this grounded theory study was to design a new model that could accommodate both directions of growth and better measure development paths with particular attention to labors contributions. The theoretical foundation for this study was Walt Whitman Rostow's 5 economic stages of growth classifications. This Study attempted to find the most common economic growth path. While most development models use three to five classifications, this study used nine new classifications giving it a unique and specific look …

Exercise Behavior Patterns In Emerging Adulthood: An Exploration Of Predictor Variables From Self-Determination Theory And Transtheoretical Model, Chad R. Johnson

College of Graduate Studies: Theses & Dissertations

During the transition from childhood to adulthood, young people establish patterns of behavior and make lifestyle choices that affect both their current and future health (NCHS, 2010). Emerging adulthood – a new conception of development for the period from the late teens through the twenties – focuses on individuals ages 18-25 who did not have a child, own a home, or have sufficient income to be fully independent (Arnett, 2000). Very little is known about social influence, motivational mediators, and motivation on exercise behavior within this developmental period. Therefore, the purpose of this study was to determine the influence of …

Adult Response To Olanzapine Or Clozapine Treatment Is Altered By Adolescent Antipsychotic Exposure: A Preclinical Test In The Phencyclidine Hyperlocomotion Model, Qing Shu, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

This study examined how repeated olanzapine (OLZ) or clozapine (CLZ) treatment in adolescence alters sensitivity to the same drug in adulthood in the phencyclidine (PCP) hyperlocomotion model. Male adolescent Sprague-Dawley rats (postnatal day (P) 44–48) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10.0 or 20.0 mg/kg, sc) and tested in the PCP (3.2 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. Then a challenge test with OLZ (0.5 mg/kg) or CLZ (5.0 mg/kg) was administered either during adolescence (~P 51) or after the rats matured into adults (~P 76 and 91). During adolescence, repeated …

Children, Adolescents And Firesetting, Joav Merrick, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

The research of firesetting has been conducted in different ways and lacks a coherent, consistent and comprehensive set of empirical findings. A recent review concluded that despite a number of risk factors being repeatedly identified, an understanding of the etiology behind firesetting behavior and potential developmental trajectories remains theoretically rather than empirically based. Existing theories do not take sufficient account of the complexities of firesetting behavior and there is not yet a typology and accompanying assessment that has undergone thorough empirical testing and is of significant clinical utility. Due to the relationship between firesetting and antisocial behavior there is a …

Self-Reported Juvenile Firesetting, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

In this chapter we address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Logistic regressions were run to determine if attention problems predicted firesetting and the findings indicated that attention problems are predictive of self-reported firesetting. The …
