A Multi-Gene By Environment Perspective Of Adhd Symptomatology In Young Children, Amber L. Allison

LSU New Orleans Theses and Dissertations

Attention deficit hyperactivity disorder (ADHD) is a heritable disorder, which has detrimental effects on childhood development and is associated with maladaptive functioning in adulthood. Despite this, we are far from an understanding of the etiology and possible trajectories of ADHD, possibly due to investigations focusing on the contribution of single genes. In fact, single genes are likely not influential enough to alter behavior, but the additive effect of many genes may predispose an individual toward certain behaviors. Further, environmental input can activate or suppress genetic expression, thereby leading to vast individual differences in both normative behavior and psychopathological illness, including …

Brief Monocular Deprivation As An Assay Of Short-Term Visual Sensory Plasticity In Schizophrenia - "The Binocular Effect", John J. Foxe, Sheralyn Yeap, Victoria M. Leavitt

Publications and Research

Background: Visual sensory processing deficits are consistently observed in schizophrenia, with clear amplitude reduction of the visual evoked potential (VEP) during the initial 50-150 of processing. Similar deficits are seen in unaffected first-degree relatives and drug-naïve first-episode patients, pointing to these deficits as potential endophenotypic markers. Schizophrenia is also associated with deficits in neural plasticity, implicating dysfunction of both glutamatergic and GABAergic systems. Here, we sought to understand the intersection of these two domains, asking whether short-term plasticity during early visual processing is specifically affected in schizophrenia.

Methods: Brief periods of monocular deprivation (MD) induce relatively rapid changes …

Factors Influencing Youth Self-Perceptions Of Overweight And Obesity, Caitlin Helen Sommers

Dissertations and Theses

This study sought to examine whether participation in physical activity affects the ability to correctly classify body size, based on body mass index classifications. Secondarily, this study determined whether adolescents who incorrectly classified their body size overestimated or underestimated their size. Self-report data from the Youth Risk Behavior Surveillance Survey collected by the Centers for Disease Control and Prevention were analyzed. Logistic regression was performed to examine relationships between self-perception of body size and physical activity, television viewing time, computer/video game use, physical education class time, and extracurricular sports activities. Significance was set to p<0.05. Physical activity was the only statistically significant independent variable (p=0.058, OR = 1.060). Although physical activity was shown to be statistically significant, it did not appear to meaningfully increase the ability of youth to correctly classify body size. Secondary analysis showed that adolescents who incorrectly classified their body size were more likely to underestimate their body size. Females more frequently underestimated their body size (females=673; males=384).

Robust Resilience: Metaphor And Meaning In Assessing System Performance Ranges, Barrett S. Caldwell

Journal of Human Performance in Extreme Environments

The current emphasis on Resilience Week and the International Symposium on Resilient Cognitive Systems highlights a growing awareness of the importance of designing and operating engineering systems under a variety of environmental conditions and in response to dynamic events. Although there has been considerable confusion and drift in the use of the term, ‘‘resilience’’ as a concept dates back to dynamic systems study of complex ecological systems in the 1970s. This original definition relates clearly to quantitative metrics that link also to statistical process control techniques describing system performance as affected by external, ‘‘assignable’’ causes. This paper discusses important elements …

Gay, Straight, Or Slightly Bent? The Interaction Of Leader Sexual Orientation And Gender On Leadership Evaluations, Fred George Macoukji

USF Tampa Graduate Theses and Dissertations

Abstract

Existing research has shown that gender stereotypes regarding characteristics of men and women influence others' perceptions of their fit with organizational roles, including leadership roles (cf. Eagly & Karau, 2002). However, little research has examined stereotypes regarding other demographic characteristics (e.g., race, sexual orientation) and how they may interact with gender stereotypes to influence leadership evaluations. The current study examined whether leader gender and sexual orientation interact to influence subordinates' evaluations of leader effectiveness, likability, and boss desirability using an experimental design. In addition to examining whether leader gender and sexual orientation interacted to predict leader evaluations, the present …

Maternal Monitoring And Maternal Psychological Well-Being: Important Components In Treating Conduct Disorder, Benjamin Rosen

Theses and Dissertations

Conduct disorder is characterized by behaviors that take a large toll on the individuals, families, and communities afflicted. Thus, improving treatment effectiveness should be a high priority. Currently, common intervention programs do not address parental depression, even though it has been linked to adolescent conduct disorder behaviors in some studies. The current study assessed whether the relation between maternal depression and adolescent conduct disorder behaviors is mediated by another factor which has been linked to conduct disorder behaviors, maternal monitoring. Results did not support the hypothesized mediated association, but did show significant individual associations for both maternal depression and maternal …

Environmental- And Ethanol-Induced Effects On Reference And Short-Term Memory In The Rat, Kimberly Ramos

Seton Hall University Dissertations and Theses (ETDs)

Environmental enrichment (EE) is a combination of complex physical and social stimulation beyond that which would be received in standard or isolated laboratory housing. Continuous enrichment paradigms have been shown, among other influences, to increase neurogenesis and dendritic branching, and enhance learning and memory. Recently, the preventative effects of enrichment have been considered, specifically relating to drugs of abuse (Solinas, Thiret, Chauvet, & Jaber 2010; Stairs & Bardo 2009). This series of studies examined the effects of daily EE on reference memory and short-term memory, as assessed in the radial arm water maze (RAWM) and Morris water maze (MWM). Sprague-Dawley …

Repeated Asenapine Treatment Produces A Sensitization Effect In Two Preclinical Tests Of Antipsychotic Activity, Rongyin Qin, Yingzhu Chen, Ming Li

Department of Psychology: Faculty Publications

Among several commonly used atypical antipsychotic drugs, olanzapine and risperidone cause a sensitization effect in the conditioned avoidance response (CAR) and phencyclidine (PCP)- induced hyperlocomotion paradigms – two well established animal tests of antipsychotic drugs, whereas clozapine causes a tolerance effect. Asenapine is a novel antipsychotic drug recently approved for the treatment of schizophrenia and manic disorders. It shares several receptor binding sites and behavioral features with other atypical antipsychotic drugs. However, it is not clear what type of repeated effect (sensitization or tolerance) asenapine would induce, and whether such an effect is transferrable to other atypicals. In this study, …

Suicide-Related Imagining And Acquired Capability: Investigating The Role Of Imagery In Self-Harm Behaviors, Tara C. Holaday

Masters Theses & Specialist Projects

The purpose of this investigation was to examine the role of suicide-related mental imagery in suicidal behavior. It was hypothesized that engagement (frequency, emotional impact, vividness, realism) with suicidal imagery would be related to suicidality, with greater engagement with imagery associated with more suicidal behaviors. Acquired capability for suicide was expected to be a mediator of this relationship. These hypotheses were tested by surveying 237 undergraduate university students (59% female; mean age = 20). Students completed a packet of self-report measures: The Modified Suicidal Cognitions Interview, The Acquired Capability for Suicide Scale, and the Self-Harm Behavior Questionnaire. Results suggested that …

Iptakalim Attenuates Self-Administration And Acquired Goal-Tracking Behavior Controlled By Nicotine, S. Charntikov, N. Swalve, Steven T. Pittenger, K. Fink, S. Schepers, G. C. Hadlock, A. E. Fleckenstein, G. Hu, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Iptakalim is an ATP-sensitive potassium channel opener, as well as an a4b2-containing nicotinic acetylcholine receptor (nAChR) antagonist. Pretreatment with iptakalim diminishes nicotine-induced dopamine (DA) and glutamate release in the nucleus accumbens. This neuropharmacological profile suggests that iptakalim may be useful for treatment of nicotine dependence. Thus, we examined the effects of iptakalim in two preclinical models. First, the impact of iptakalim on the interoceptive stimulus effect of nicotine was evaluated by training rats in a discriminated goal-tracking task that included intermixed nicotine (0.4 mg/kg, SC) and saline sessions. Sucrose was intermittently presented in a responseindependent manner only on nicotine sessions. …

Feeling Sad? Maybe You Are Just Uncertain! A Predictive Test For Depression, Dana Elizabeth Larson

Masters Theses & Specialist Projects

The current study examined the relationship between depression and uncertainty within the stress-diathesis model. Depression is a mental health disorder that is wide spread within our society. However, few causes of this disease have been able to be identified. Studies in uncertainty have shown that it is a major stressor in day-to-day life. Previous research has shown that individuals with high levels of uncertainty show higher levels of depression. The stress-diathesis model, a model originally developed to explain differences in development of schizophrenia, provides a theoretically meaningful way to combine these two concepts. The model states that a person who …

Pilates, Mindfulness And Somatic Education, Karen Caldwell, Marianne Adams, Rebecca Quinn, Mandy Harrison, Jeffrey M. Greeson

College of Science & Mathematics Departmental Research

The Pilates Method is a form of somatic education with the potential to cultivate mindfulness – a mental quality associated with overall well-being. However, controlled studies are needed to determine whether changes in mindfulness are specific to the Pilates Method or also result from other forms of exercise. This quasi-experimental study compared Pilates Method mat classes and recreational exercise classes on measures of mindfulness and well-being at the beginning, middle and end of a 15 week semester. Total mindfulness scores increased overall for the Pilates Method group but not for the exercise control group, and these increases were directly related …

Psychometric Properties Of The Adolescent Sleep Hygiene Scale, Amy Storfer-Isser, Monique K. Lebourgeois, John Harsh, Carolyn J. Tompsett, Susan Redline

Faculty Publications

This study evaluated the psychometric properties of the Adolescent Sleep Hygiene Scale (ASHS), a self-report measure assessing sleep practices theoretically important for optimal sleep. Data were collected on a community sample of 514 adolescents (16–19; 17.7 ± 0.4 years; 50% female) participating in the late adolescent examination of a longitudinal study on sleep and health. Sleep hygiene and daytime sleepiness were obtained from adolescent reports, behavior from caretaker reports, and sleep-wake estimation on weekdays from wrist actigraphy. Confirmatory factor analysis indicated the empirical and conceptually based factor structure were similar for six of the eight proposed sleep hygiene domains. Internal …

The Impact Of An Interdisciplinary Learning Community Course On Pseudoscientific Reasoning In First-Year Science Students, Timothy Franz, Kris H. Green

Psychology Faculty/Staff Publications

This case study examined the development and evaluation of an interdisciplinary first-year learning community designed to stimulate scientific reasoning and critical thinking. Designed to serve the needs of scholarship students majoring in mathematics and natural sciences, the six-credit learning community course was writing-intensive and emphasized general scientific reasoning and critical thinking skills. Success of the course was measured using a pre-test/post-test design that assessed students’ paranormal beliefs. Outcomes of the study indicated students’ paranormal beliefs were significantly lower at the end of the semester than at the beginning, which was used as a surrogate measure of scientific reasoning that was …

Combining Attentional Control And Semantic Memory Retrieval: A Sensitive Marker For Early Stage Ad And Ad-Related Biomarkers In Healthy Older Adults, Andrew Jacob Aschenbrenner

All Theses and Dissertations (ETDs)

Past studies have shown that measures of attentional control and semantic memory retrieval are sensitive markers of Alzheimer disease: AD). The present study examined the utility of combining measures of attentional control and semantic retrieval within a single task to discriminate healthy aging from early stage AD and show sensitivity to AD biomarkers in healthy control individuals. On each trial of the present task, participants viewed a category: e.g. “a unit of time”) and verified whether a subsequent target item was an exemplar of the category: “hour”) or not: “clock”). Importantly, the nonmembers of the category were associatively related: e.g., …

The Effects Of Gender On Anxiety Sensitivity In Relation To Interoceptive Task Performances : An Exploratory Study., Brittany Deanne Miller

College of Arts & Sciences Senior Theses

This study examined whether males or females have higher anxiety sensitivity, and how this may affect performance on interoceptive tasks. Females in this study, reported significantly higher rates of anxiety sensitivity than males, as measured by the Anxiety Sensitivity Index-3 (Taylor et al., 2007). No significant gender differences were found on either of two interoceptive sensitivity tasks, the Schandry Heartbeat Detection task (Schandry, 1981) and the Mindfulness Interoceptive Sampling Task (Dreeben, 2012). Results of this study suggest that, although females have higher self-reported anxiety sensitivity than males, this does not appear to either enhance or hinder their performance on interoceptive …

The Separate And Combined Effects Of Heredity And Environment Predicting Alcohol Use Disorder Symptoms And Antisocial Personality Disorder Symptoms, Jaylee R. Gill

Honors Theses

The current study examined genetic and environmental influences in relation to alcohol use pathology. The 756 participants (378 adoptive, 378 non-adoptive) came from the 2001-2002 NESARC conducted by the NIAAA. A factorial ANOVA was used to measure the effects that the three grouping variables had on each dependent variable for a total of seven datasets. Results showed that biological parents’ drinking did pose a risk in participants for Loss of Control (p = .000) and Dangerous Behavior (p = .00). Adoption status was correlated with Conduct Disorder (p = .007) and Antisocial Personality Disorder (p = .014). This suggests that …

Congruent And Incongruent Effects Of Ethnic Music On Ethnic Menu Item Selection, Ryan David Muniz

Graduate Theses and Dissertations

This study investigated what impact ethnic music had on ethnic menu item selection. College students were randomly divided into three groups and listened to one randomly assigned sound treatment in sensory booths. Three hundred and five participants completed the questionnaire with measures of expected price value and willingness to pay value. One of the groups listened to an Italian folk music, the second group listened to a Thai folk music, and the third group listened to a restaurant background noise in order to examine if the music will impact each participant menu items selection and perceived price values. The result …

The Role Of Expectations In The Perceived Usefulness And Acceptance Of Virtual Reality As A Preventative Technique For Post-Traumatic Stress Disorder, Christine Kreutzer

HIM 1990-2015

Expectancy theory is based on the subjective probability (expectancy) and projected value (valence). Based on this notion, an individual chooses his or her behaviors based on the interaction between the valences perceived to be associated with the outcomes, and the appraisal of the probability of that behavior resulting in those outcomes. Expectancies have been found to be predictive of many outcomes, such as treatment outcomes, behavioral change, and training reactions. The goal of the present study is to empirically investigate this issue within the mental health field. While virtual reality appears to be a promising preventative technique for posttraumatic stress …

A Good Old Age: Experiencing A Satisfying Life, Kaitlin Thimann

Boise State University Theses and Dissertations

The definition of successful aging has been changing, however, there is a lack of current studies on existing aging trends and how to experience a good old age. The purpose of this study is to identify and describe themes and factors that can lead to an individual experiencing a good old age. This study is a qualitative, exploratory ethnography in which interviews were used to gather information on a good old age from adults aged sixty-five and older. The study revealed that there were several common factors throughout the interviews. Physical and mental health, social support, and financial stability are …

What Works In Suicide Bereavement: What Helps And What Hurts?, Quintin Hunt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Suicide is one of the most painful grief experiences that any family may experience. The suicide bereavement literature, though small, is replete with research that shows family and systemic impacts of suicide. The literature also includes constant calls for family- and systemic-based intervention as every part of society is impacted. Research in the field of marriage and family therapy, however, has ignored suicide and suicide bereavement almost entirely. The purpose of this qualitative study is to develop a more thorough understand of the grief that survivors of suicide experience and to systemically understand what helps and hurts the grieving process. …

Examining The Inner Experience Of Four Individuals With Bipolar Disorder Using Descriptive Experience Sampling, Johanah Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is a lifelong mood disorder with diagnostic criteria that provide a description of expected experiences of individuals diagnosed with BD (e.g., elevated mood, sadness, difficulty concentrating). Despite these criteria, the inner experience of these individuals is largely unknown. Understanding the inner experience of individuals diagnosed with BD may prove essential in understanding and treating BD. The present study examined the inner experience of four individuals diagnosed with BD using the Descriptive Experience Sampling (DES) method (Hurlburt 1990, 1993, 2011). Results revealed all our participants had clear and prevalent experiences of sensory awareness. They also had difficulties apprehending and …

Perceptions And Definition Of Infidelity: A Multimethod Study, Sarah Schonian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Most couples in committed relationships have implicit or explicit rules regarding infidelity. However, not all partners view infidelity in the same way, and the discrepancy in opinions can lead to problems in the relationship and can complicate the healing process. The purpose of this study was to better understand how people define infidelity and the variables that influence perceptions about infidelity. A mutlimethod design was used to collect quantitative and qualitative data on participants' perceptions and definitions of infidelity. Quantitative data was collected through participants' answers to questions on a scale about perceptions of potentially unfaithful behaviors that was developed …

The Role Of Music-Specific Representations When Processing Speech: Using A Musical Illusion To Elucidate Domain-Specific And -General Processes, Christina M. Vanden Bosch Der Nederlanden

UNLV Theses, Dissertations, Professional Papers, and Capstones

When listening to music and language sounds, it is unclear whether adults recruit domain-specific or domain-general mechanisms to make sense of incoming sounds. Unique acoustic characteristics such as a greater reliance on rapid temporal transitions in speech relative to song may introduce misleading interpretations concerning shared and overlapping processes in the brain. By using a stimulus that is both ecologically valid and can be perceived as speech or song depending on context, the contribution of low- and high-level mechanisms may be teased apart. The stimuli employed in all experiments are auditory illusions from speech to song reported by Deutsch et …

Counseling clients are increasingly presenting with problematic issues regarding Internet pornography use. The purposes of this mixed-method study were (a) to examine the current status of counselors’ attitudes and self-efficacy about treating clients with Internet pornography addiction, and (b) to ascertain the opinions of counselor educators who are experts in the field of Internet pornography addiction on the current status of counselor training and best practices for preparing counselors.

The quantitative data was obtained from a 90-item …

Interaction Of Parent Pain And Child Empathy On Child Depression: A Pilot Study, Ketlyne Sol

Loma Linda University Electronic Theses, Dissertations & Projects

Children aged 11-17, in their relationships with their parents, are capable of experiencing a negative mood if their parent is in pain. According to the empathy-altruism hypothesis, people that are high on empathy will want to help someone in distress with the ultimate goal of benefitting the other person. Because of this, the empathy-altruism hypothesis proposes that if an attempt to help is not resolved, the person will report more negative mood. Because children are capable of experiencing empathy for their parents in distress and feel a negative mood as a result, it was hypothesized that an interaction between empathy …

Preparing Mental Health Professionals For Work In Collaborative Care Settings, Angela G. Hester

Loma Linda University Electronic Theses, Dissertations & Projects

There has been a significant shift regarding how health and illness are conceptualized. In decades past, the biomedical model predominated. Factors other than biological were not seen as important with regard to the diagnosis and treatment of illness; mind and body were viewed as separate. Engel’s 1977 article challenged the biomedical perspective with the biopsychosocial model, suggesting the reciprocal nature of biological, psychological and social factors on patients’ experience of health and illness, and responsiveness to treatment interventions. While viewing individuals holistically was not a new concept at that time, several factors led the biopsychosocial model to gain wide acceptance …

The 2 goals of the present investigation were to 1) examine the reliability of the Children’s Behavior Questionnaire: Short Form (CBQ) in a sample of 4-7 year-old children from the Ukraine and 2) compare those children’s temperament profiles to a) one another when the form was administered in 2 different languages and b) their American counterparts from the CBQ standardization sample. Three waves of data were collected from the parents of 167 children residing in Kiev, Ukraine. Internal reliability analyses showed good internal consistency of the instrument. Comparative analyses conducted both within and between cultures showed similarities and differences across …

Children's Recognition Of Pride: An Experimental Approach, Darren Jason Garcia

Theses and Dissertations

Pride is elicited when a child takes credit for an achievement or exceeds a socially valued standard or expectation. Evidence suggests that pride has a distinct nonverbal expression that is recognized by adults across cultures (Tracy & Robins, 2004). Research examining when children recognize pride has yielded age discrepancies between studies that use forced-choice response formats and those that use spontaneous-response formats. Differences in children's ability to use and comprehend language may account for some of these differences. The purpose of this thesis was to examine the age at which children reliably recognize pride, while minimizing the need for children …

Evaluation Of The Relationship Between Nutrition Knowledge And Disordered Eating Risk In Female Collegiate Athletes, Amy L. Miracle

UNLV Theses, Dissertations, Professional Papers, and Capstones

Involvement in collegiate sports among female athletes is at an all-time high with approximately 198,000 currently participating, (National Collegiate Athletic Association, 2012). With this increase in female participation in collegiate sports, the pressures of sport participation and academics lead some women to engage in harmful eating behaviors. These harmful eating behaviors may lead to the development of disordered eating (C. Johnson, Powers, & Dick, 1999; Quatromoni, 2008; Reel, SooHoo, Petrie, Greenleaf, & Carter, 2010; Reinking & Alexander, 2005). Many factors have been identified as contributing to the development of disordered eating but nutrition knowledge or lack thereof, has yet to …
