The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals, Randall L. Miller

Seton Hall University Dissertations and Theses (ETDs)

Healthy individuals do not perceive the left and right sides of space equally, showing a leftward spatial bias on visuospatial tasks. This bias may be more attributed to a perceptual-attentional (PA) component than a motor-intentional (MI) component. While monocular eye patching alters this spatial bias via modification of PA but not MI, hemifield eye patches that occluded the left or right half of the visual field have been shown to be more effective at modifying spatial bias, but only in patients with spatial neglect. Furthermore, it is unclear whether hemifield patching affects PA, MI, or both. The goal of the …

Sustained And Transient Reward Effect On Cognitive Control In Schizophrenia: The Relevance Of Negative Symptoms, Yu Sun Chung

All Theses and Dissertations (ETDs)

Schizophrenia (SCZ) is characterized by severe cognitive impairments and amotivation, generally referred to as negative symptoms, including anhedonia and/or avolition. Amotivation tends to exist in prodromal patients and persist over the illness course regardless of successful antipsychotic medications, which are known to reduce positive symptoms, including hallucination and delusions (e.g., (Horan, Blanchard, Clark, & Green, 2008; Tarbox et al., 2013). Importantly, amotivation is a promising predictor for later social functioning in SCZ, even after accounting for patients' cognitive impairments (e.g., (Evensen et al., 2012; Faerden et al., 2010). Despite this crucial impact on functioning outcome in SCZ, to date, no …

Bursts And Heavy Tails In Temporal And Sequential Dynamics Of Foraging Decisions, Kanghoon Jung, Hyeran Jang, Jerald D. D. Kralik, Jaeseung Jeong

Dartmouth Scholarship

A fundamental understanding of behavior requires predicting when and what an individual will choose. However, the actual temporal and sequential dynamics of successive choices made among multiple alternatives remain unclear. In the current study, we tested the hypothesis that there is a general bursting property in both the timing and sequential patterns of foraging decisions. We conducted a foraging experiment in which rats chose among four different foods over a continuous two-week time period. Regarding when choices were made, we found bursts of rapidly occurring actions, separated by time-varying inactive periods, partially based on a circadian rhythm. Regarding what was …

Longitudinal Perspective Of Participation In A Double Blind Placebo Surgery Trial, Jessica Kuhne

Electronic Theses and Dissertations

Parkinson’s disease (PD) is a chronic and progressive neurological disorder that causes both motor symptoms and non-motor symptoms in individuals. Overall, PD impacts the physical, emotional and social functioning in the lives of those impacted by the disorder. In 2001, Freed et al. investigated the effects of fetal tissue transplantation in participants with PD by conducting a double-blind sham-controlled surgery trial. The quality of life (QoL) study was conducted concurrently by McRae et al. (2004) in order to determine whether QoL improved in participants in the transplant group compared to the sham group after the one-year period of the double-blind. …

Obstructive Sleep Apnea Syndrome And Neuropsychological Dysfunction: Understanding The Impact Of Obesity, Chelsea A. Hilsendager

Electronic Theses and Dissertations

Obesity is the largest risk factor for the development of obstructive sleep apnea syndrome (OSAS), which is a common sleep-related breathing disorder that is associated with cognitive dysfunction. A growing body of literature suggests that obesity is related to negative neuropsychological outcomes independent of other health problems known to impact cognitive functioning (e.g., type II diabetes, cardiovascular disease). The purpose of this study was to investigate the impact of obesity on the cognitive functioning of individuals with OSAS. Specifically, this study aimed to examine whether or not differences existed between obese and non-obese persons with OSAS on a battery of …

Studying Eye Gaze Of Children With Autism Spectrum Disorders In Interaction With A Social Robot, Huanghao Feng

Electronic Theses and Dissertations

Children with Autism Spectrum Disorders (ASDs) experience deficits in verbal and nonverbal communication skills including motor control, emotional facial expressions, and eye gaze attention. In this thesis, we focus on studying the feasibility and effectiveness of using a social robot, called NAO, at modeling and improving the social responses and behaviors of children with autism. In our investigation, we designed and developed two protocols to fulfill this mission. Since eye contact and gaze responses are important non-verbal cues in human's social communication and as the majority of individuals with ASD have difficulties regulating their gaze responses, in this thesis we …

Professional Opinion On The Use Of Interest Inventories In Employee Selection, Amy Mandelke

Masters Theses & Specialist Projects

Although interest inventories have a long history in the field of career counseling, vocational interests have received limited attention in Industrial-Organizational (I-O) psychology. To assess the potential utility of interest inventories in the field of I-O psychology, 82 I-O psychologists with expertise in employee selection and equal employment opportunity law completed a survey assessing their expert opinion on the utility of interest inventories for employee selection decisions. Opinion on potential legal liability and discriminatory impact of the use of interest inventories was also assessed. Hypothesis 1, which stated a majority of respondents would indicate they have little to moderate knowledge …

Effect Of Environmental Cues On Behavioral Efficacy Of Haloperidol, Olanzapine And Clozapine In Rats, Tao Sun, Xinfeng Liu, Ming Li

Department of Psychology: Faculty Publications

Previous studies have reported that context can powerfully modulate the inhibitory effect of an antipsychotic drug on phencyclidine (PCP)-induced hyperlocomotion (a behavioral test used to evaluate putative antipsychotic drugs). The present study investigated the experimental conditions under which environmental stimuli exert their influence through associative conditioning processes. Experiment 1 examined the extent to which prior antipsychotic treatment in the home cages affected a drug’s ability to inhibit PCP-induced hyperlocomotion in a novel motor activity test apparatus. Five days of repeated haloperidol (0.05 mg/kg, sc) and olanzapine (2.0 mg/kg, sc) treatment in the home cages still potentiated their inhibition of PCP-induced …

PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation.

OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after …

The Cessation Of Nssi: Differences In Acquired Capability And Distress Tolerance, Rondel T. Kittleman

Masters Theses & Specialist Projects

The purpose of this investigation was to examine the role of cessation of NSSI in acquired capability and distress tolerance. It was hypothesized that individuals with longer time in-between assessment and NSSI would show lower levels of acquired capability and higher levels distress tolerance regardless of lifetime frequency. These hypotheses were tested by surveying 375 undergraduate university students (64% female; mean age = 20.3) Participants completed packets with self-report measures that included: Inventory of Statements about Self- Injury, Acquired Capability of Suicide Scale, Distress Tolerance Scale, and Demographics. Results suggested that individuals with longer amount of time since last NSSI …

Interactions With Horses Is Associated With Higher Mindfulness And Heart Rate Variability And Lower Electrodermal Response In College Students, Sarah Mary Wach

USC Aiken Psychology Theses

A wealth of research has revealed psychological and physiological benefits of interactions with animals. As yet, research is limited to smaller animals such as dogs and cats and has not examined the benefits of human-horse interactions. The present study examined the effects of video-simulated human-horse interactions compared with simulated interactions with a car and a person on state mindfulness and physiological arousal. The relationship between trait mindfulness and horse experience was also examined. Undergraduate students with (n = 16) and without experience with horses (n = 26) were recruited with the exclusion criteria of a fear of horses. …

Obstetrics and Gynaecology, East Africa

Background: Rape of women and children is recognized as a health and human rights issue in Tanzania and internationally. Exploration of the prevailing perceptions in rural areas is needed in order to expand the understanding of sexual violence in the diversity of Tanzania’s contexts. The aim of this study therefore was to explore and understand perceptions of rape of women and children at the community level in a rural district in Tanzania with the added objective of exploring those perceptions that may contribute to perpetuating and/or hindering the disclosure of rape incidences.

Methods: A qualitative design was employed using focus …

Generalization Of Fear Effects In Reinstatement To A Discrete Stimulus, Lauren Best

USC Aiken Psychology Theses

The purpose of this study was to investigate generalization of reinstated fear effects to a discrete stimulus. McAllister and McAllister (2006) reported that reinstated fear could generalize over time to similar contexts. The present study aimed to determine if reinstated fear could generalize to similar or different stimuli than conditioning after a long delay between reinstatement and testing. Rat subjects were randomly assigned to six groups (n = 10) which received conditioning and extinction to a 3000 Hz tone. Reinstatement conditioning was then conducted with either the same, similar, or different CS as used in conditioning. Testing for reinstated fear …

Do Social Communication Skills Mediate The Relation Between Adhd Symptoms And Reltionship Satisfaction?, Erin Clarke Bell

Dissertations

Very few studies have examined adult attention-deficit/hyperactivity disorder (ADHD) and relationship satisfaction. The current study focused on ADHD symptoms, social communication skills, and relationship satisfaction. Based on previous research that provides evidence that individuals with ADHD tend to have more difficulty with both receptive and expressive social communication skills as well as the large amount of evidence that communication is a key component to relationship satisfaction, it was expected that higher ADHD symptoms in one partner of a romantic dyad would relate to less relationship satisfaction. Furthermore, because ADHD is associated with a positive illusory bias (PIB), it was also …

A Description Of Vocalizations And Their Association With Mouthing Behaviors And Social Context In Bottlenose Dolphins, Tursiops Truncatus, Christina Elyse Perazio

Master's Theses

Dolphin communication is multimodal and incorporates physical behaviors and vocalizations. Dolphins often exchange information with conspecifics using different types of vocalizations, and these vocalizations are sometimes associated with specific behaviors. However, the relationship of vocalization type and mouthing behavior type has not been investigated. This thesis examines simultaneous acoustic and visual recordings of bottlenose dolphins (Tursiops truncatus) to determine the relationship between type of mouthing behavior and type of vocalization (whistle, whistle-squawk, chirp, moan, burst-pulse type A, burst-pulse type B, and click trains). The role of the social context of a mouthing behavior is also evaluated. Data were obtained opportunistically …

The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones

Master's Theses

The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …

What Do Children Know Before Spelling Phonologically? Prephonological Spellers’ Knowledge Of Writing, Lan Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Most theories of literacy development have focused on children’s knowledge of the phonological aspect of writing. Relatively few studies have investigated children’s writing-related knowledge before they acquire alphabetic knowledge. The constructivist theory provides insights into what and how children know about other aspects of writing such as its graphic properties and symbolic function. The present study examined different aspects of the constructivist perspective. Preschool children with a mean age of 4 years and 4 months completed a spelling task and a recognition task. Participants who had not grasped conventional phoneme-grapheme correspondences in English were of primary interest. Consistent with the …

The Effect Of Naltrexone On Nicotine-Induced Conditioned Place Preference In Rats, Jonathan M. Adams

All NMU Master's Theses

Nicotine is the central active ingredient in tobacco. The reinforcing effects of nicotine can be studied in animals through self-administration, conditioned place preference, and other approaches that enable researchers to assess nicotine cessation strategies. One strategy involves the use of opioid receptor antagonists. For instance, naloxone has been shown to reduce place preference for nicotine in rats, and other experimental opioid antagonists have also been shown to affect place preference for nicotine. The present study sought to extend these findings to the opioid antagonist naltrexone, which has long been FDA-approved for the treatment of opioid and alcohol addiction in humans. …

The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker

Masters Theses

In recent years, researchers have evaluated individuals' preferences for different mand modalities and its effects on the acquisition of novel mands during functional con1munication training (i.e., FCT; e.g., Falcomata, Ringdahl, Christensen, & Boelter, 20 I 0). In many of these studies, the modality of responding that Michael ( 1985) classified as selection-based responding, is preferred by participants (e.g., Falcomata et al., 201 0). Wraikat, Sundberg, and Michael (1991) suggest that topography-based responses may be preferable for the acquisition of complex language. However, selection-based verbal responses may have faster acquisition in learning initial verbal operants (Charlop-Christy, Carpenter, Le, LeBlanc & Kellet, …

A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla

Masters Theses

Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify …

Development And Testing Of The Home Safety And Beautification Checklist With Mothers Referred For Child Neglect And Substance Abuse, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unintentional injury is the leading cause of death among children in the United States accounting for nearly 40 percent of deaths in this age group. Approximately 50 percent of nonfatal injuries, and 40 percent of fatalities, occur in and around the home. Elevated rates of child injury in the home environment are associated with parental substance abuse and neglectful behaviors. Childhood injuries are preventable, yet practical and cost-effective measures to identify child home safety risks are limited. This study involved a retrospective preliminary examination of the Home Safety and Beautification Checklist (HSBC) in a sample of drug-abusing mothers referred by …

The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague

Electronic Theses and Dissertations

Amyotrophic lateral sclerosis and other neurodegenerative disorders can cause individuals to lose control of their muscles until they are unable to move or communicate. The development of brain-computer interface (BCI) technology has provided these individuals with an alternative method of communication that does not require muscle movement. Recent research has shown the impact psychological factors have on BCI performance and has highlighted the need for further research. Working memory is one psychological factor that could influence BCI performance. The purpose of the present study is to evaluate the relationship between working memory and brain-computer interface performance. The results indicate that …

Differences In Narcissistic Presentation In Abused And Non-Abused Children And Adolescents, Mallory Laine Malkin

Dissertations

The present study examined whether children and adolescents who have been victims of sexual or physical abuse report higher levels of narcissistic tendencies than children and adolescents who have not been victims of abuse. Inaddition to narcissism, internalizing symptoms, externalizing behaviors, and risky behaviors were evaluated, as such issues have been associated with both maltreatment (Baer & Maschi, 2003) and narcissism (Barry & Malkin, 2010; Bushman & Baumeister, 1998). One-hundred fifty- six (156) children and adolescents (100 females, 56 males) ranging in age from 8 to 17 (M = 12.90, SD = 2.66) were recruited as participants. The vast majority …

The Perception Of Distance On A Real Geographic Slope, David Alan Bunch

Dissertations

Ooi, Wu, and He (2001) have shown that for objects resting on flat, horizontal surfaces, those that appear in the lower sector of the visual field are perceived as close to the observer and objects located near the visual horizon are perceived as further from the observer. Researchers have hypothesized that observers utilize the angle subtended between the horizon and the line of sight to the target object as information for distance.In a previous investigation Hajnal, Bunch, and Kelty-Stephen (2014) showed that an object’s physical angle of declination below the horizon is not uniquely utilized when making distance estimates to …

Effects Of Animal Management Changes On The Activity Budgets And Walking Rates Of Zoo Elephants, Angela Dawn Mackey

Dissertations

The current study aimed to assess the effects of two management strategies, weekly rototilling of the enclosure and the provision of unpredictable foraging opportunities, on the daily behavior of six elephants housed at the San Diego Zoo. Observations took place from January to June 2013 and were conducted throughout a 24- hour period. The study was divided into three phases, each two months in duration. During the first phase (baseline) no changes were made to the current management routine of the elephants. In Phase 2, rototilling of the elephant enclosures was increased from once monthly to once per week, while …

The Effect Of 0.2 Hz And 1.0 Hz Frequency And 100 Ms And 20 - 100 Ms Amplitude Of Latency On Simulatory Sickness In A Head Mounted Display, Amelia Kinsella

All Theses

The purpose of the current experiment was to contribute to the existing literature on the relationship between frequency of latency and amplitude of latency and simulator sickness experienced in a head mounted display (HMD). Motion sickness has been studied for decades in a variety of vehicles including ships, planes, trains and automobiles. More recently virtual environments, including those utilizing an HMD have been shown to generate significant sickness, often termed simulator sickness. Many studies have linked system latency to simulator sickness and recent research has found that with current technology latency is not a constant; but rather it varies systematically …

The Effect Of Acute Lps-Induced Immune Activation And Brain Insulin Signaling Disruption In A Diabetic Model Of Alzheimer's Disease, Andrew Scott Murtishaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a neurodegenerative disorder marked by progressive cognitive impairments and pathological hallmarks that include amyloid plaques, neurofibrillary tangles, and neuronal loss. Several well-known mutations exist that lead to early-onset familial AD (fAD). However, these cases only account for a small percentage of total AD cases. The vast majority of AD cases are sporadic in origin (sAD) and are less clearly influenced by a single mutation but rather some combination of genetic and environmental risk.

The etiology of sAD remains unclear but numerous risk factors have been identified that increase the chance of developing AD. Among these risk …

Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychotic symptoms in bipolar I disorder during mood episodes has been associated with several negative outcomes raising the question as to whether psychosis is a risk factor for a more severe form of this chronic and debilitating condition. However, relatively little research has been directed at understanding the relationships among social cognitive functioning in bipolar I disorder with and without a history of psychosis. Impaired social cognition has been identified as a putative endophenotypic markers in schizophrenia and the evidence is mounting as to whether similar impairments also exist in bipolar I disorder. Given the plethora of research supporting the …
