Object Categorization In Children With Autism Spectrum Disorder (Asd), Jaime Vitrano

Dissertations, Theses, and Capstone Projects

The purpose of this study was to investigate hierarchical object categorization in children with autism spectrum disorder (ASD), examining three levels of category inclusiveness (superordinate, basic, subordinate) across three tasks (sequential touching task, generalized imitation task, sorting task) in three domains (animals, tools, kitchen utensils) in the same group of children with ASD. Previous research on the categorization abilities of children with ASD has shown mixed results. This study was designed to clarify past discrepancies in the literature.

Ten children with ASD participated in this study (mean CA = 4 years, 10 months; range 3 to 6 years; mean VMA …

Black Like Me? A Narrative Study Of Non-Anglophone Black U.S. Immigrant Selves In The Making, Yvanne Joseph

Dissertations, Theses, and Capstone Projects

The passage of the 1965 Immigration and Nationality Act abolished discriminatory national origin quotas that favored European immigrants. The U.S. has since experienced steady flows of immigrants of color. These diverse groups have brought their racial, social, cultural and historical experiences, which adds greater complexity to the existing Black/White and ingroup/outgroup models that shape group relations, and psychological theorizing about identity. This dissertation focuses specifically on the smaller, less visible, yet growing segments of these immigrant populations. It presents a study of the lives of ten individual immigrants of African descent originating from a non-Anglophone country within Africa, Latin America …

Triple Stigma In Forensic Psychiatric Patients: Mental Illness, Race, And Criminality, Michelle Leigh West

Dissertations, Theses, and Capstone Projects

Stigma involves negative beliefs and devaluations of people in socially identified groups (e.g. race, mental illness). Although people have many reactions to social stigma, some labeled people internalize these attitudes. Research has increasingly explored mental illness self-stigma, when people with mental illness begin to believe that society's negative beliefs are true of them (e.g., that they are hopeless due to mental illness). Self-stigma predicts poorer functional and treatment outcomes. Stigma research has typically investigated stigmatized labels individually. Forensic psychiatric patients, people with mental illness with history of criminal conviction, by definition experience multiple stigmas, yet no research has explored how …

Generalized Event Representation In Pre-School Children With Mild- To High-Functioning Autism Spectrum Disorder (Asd) And Children With Cognitive And Linguistic Delays (Cld), Tashana S. Samuel

Dissertations, Theses, and Capstone Projects

Children with autism spectrum disorder (ASD) frequently establish rigid routines and have difficulties flexibly applying what they have learned. Three experiments were conducted to examine generalized event representation in 34 pre-school children. In Experiment 1, children diagnosed with varying kinds of cognitive and language delays (CLD: n = 14) were tested with the generalized imitation paradigm, a reliable measure of representational capacity. Two sets of perceptually dissimilar objects with similar functions were used to perform the same task: one set consisted of modeling props and the other set was the generalization props. At the generalization assessment, children observed actions modeled …

The Role Of Emotional Support Consistency And Child Risk Factors In Predicting Pre-K Cognitive And Social-Emotional Development, Amy Lynn Cannell-Cordier

Dissertations and Theses

The quality of children's daily experiences in preschool classrooms is predictive of their school readiness and later achievement (Duncan et al., 2007; La Paro & Pianta, 2000). One particularly important aspect of these experiences is the quality of emotional support provided by teachers and peers in the classroom (Hamre & Pianta, 2005; Howes et al., 2008; Mashburn, 2008; National Center on Quality Teaching and Learning, 2012). Traditionally, emotional support quality has been calculated as the average of ratings taken across the school year and is meant to represent children's average daily experience, without regard to any variability which exists within …

Investigating Sleep Behaviors In Autistic Infants, Alanna R. Flynn

Undergraduate Honors Theses

Autism Spectrum Disorder (ASD) is defined by social, emotional, and learning deficits. Past research suggests that ASD and sleep problems often co-occur. The goal of this research was to investigate sleeping behaviors in autistic infants in comparison to typically developing infants (TD). The data of this study has been acquired at the University of California San Diego Autism Center of Excellence. One main goal of this center is to identify early indicators of ASD in infants (1-3 years of age), which could lead to earlier treatment and better therapy techniques. The current study used a sleep questionnaire to compare parent-reported …

Summary Of The Performance Effects Of Sustained Operations, Valerie Gawron

Journal of Human Performance in Extreme Environments

Sustained operations missions are performed in diverse environments. These environments include military command and control, process control, medical practice, and security surveillance. Research on the related fatigue effects of sustained operations is reviewed for each of these diverse environments. For military surge operations, both ground and airborne command and control operators show similar decrements in visual performance as a function of sleep loss. Other decrements include increased number of errors in vigilance tasks and reaction time tasks. In process control experiments, longer shifts resulted in more variance in reaction time to grammatical reasoning tasks. Night shift was associated with slower …

Gender Differences In The Relationship Between Impulsivity And Disordered Eating Behaviors And Attitudes, Alyssa Lundahl, Laura C. Wahlstrom, Christa C. Christ, Scott F. Stoltenberg

Department of Psychology: Faculty Publications

Objective: We investigated relationships among gender, impulsivity and disordered eating in healthy college students.

Method: Participants (N = 1223) were healthy, undergraduate men (28.5%) and women (71.5%), who completed the Barratt Impulsiveness Scale — Version 11 (BIS-11) and a four-factor version of the Eating Attitudes Test (EAT-16).

Results: As predicted, mean scores on all four EAT-16 factors were significantly higher for women than for men. Attentional impulsivity was related to poorer self-perception of body shape, more dieting, and a greater preoccupation with food for the sample as a whole. Moreover, motor impulsivity was related to poorer self-perceptions of body shape …

The Relation Of Hyperactivity To Parenting Stress Within The Parent-Child Relationship In Children With Autism Spectrum Disorders, Heather Davis

Clinical Psychology Dissertations

Research indicates that parents of children with autism spectrum disorder (ASD) experience more total stress and more stress within specific domains of the parent-child relationship. Specific externalizing behaviors such as hyperactivity have been related to elevated adverse parent-child outcomes in families with typically developing children. To date, the relation of child hyperactivity to parenting stress has not been examined in children with ASD. This study investigated the extent to which child hyperactivity differs between children who are typically developing (TD) and children with ASD. In addition, this study also examined the relation of child hyperactivity to parenting stress. Participants included …

An Investigation Of Short-Term Memory Functioning In A Neurodevelopmental Rat Model Of Schizophrenia, Ashley M. Moyett

Seton Hall University Dissertations and Theses (ETDs)

Schizophrenia is a debilitating disorder characterized by positive, negative, and cognitive symptoms. Cognitive deficits affect one’s learning and memory due to a dysfunction in the brain, inhibiting a normal functioning life. The self-medicating hypothesis states that ninety percent of people with schizophrenia smoke, because nicotine use improves these cognitive deficits. The cytokine hypothesis states that inflammation due to prenatal infection is associated with schizophrenia. These increased proinflamatory cytokines can damage the brains of the fetuses, which can cause schizophrenic-like symptoms in rats. The present study used Lipopolysaccharides to activate the cytokine-mediated inflammatory response injected into pregnant dams. A T-maze was …

Arts & Sciences Graduate Student Theses and Dissertations

This study evaluated the impact of an interdisciplinary course on aging designed to improve attitudes toward older adults and aging, and generate interest in aging-related careers. Main outcomes included knowledge of older adults and aging, attitudes toward older adults and aging, and anxiety about personal aging. Participants included first-year undergraduate students enrolled in the course (curricular intervention group) and first-year undergraduate students not enrolled in the course (control group). Data were collected at the beginning and end of one semester. At the end of the semester curricular intervention students had increased in their knowledge about aging and showed more positive …

Effects Of Rhes Prenylation On Mouse Cognition In A 3-Nitropropionic Acid Animal Model Of Huntington's Disease, Diana Hobbs

LSU New Orleans Theses and Dissertations

Located on the short arm of chromosome 4, there exists a gene, IT15, responsible for the trinucleotide CAG expansion involved in the autosomal dominant neurodegenerative disorder known as Huntington’s disease (HD). The brain region associated with the most atrophy, the striatum, leads to expression of severe motor dysfunction, the hallmark feature of HD. To a lesser degree, the cortex and hippocampus show earlier deterioration indicative of the cognitive deficits that occur prior to motor symptom onset. The brain regions associated with HD-induced neuronal death additionally selectively express the protein Rhes - the combination of Rhes and mutant huntingtin being cytotoxic. …

Functional Analysis Of Gambling, Mack S. Costello

Dissertations

Given high rates of gambling and the growing population of disordered gamblers, there is a need to develop assessment strategies with improved treatment validity. More specifically, assessment strategies are needed that identify the controlling variables for disordered gambling and, thus, provide guidance in the selection of treatment and prevention strategies. This study sought to develop a functional analysis for gambling by utilizing a simulated gambling environment in which contextual variables hypothesized to be causally linked to disordered gambling could be systematically manipulated. Seven experienced gamblers participated in the multi-element, single-subject experimental study. Participants who endorsed at least some problems from …

A Conceptual Framework Of Computations In Mid-Level Vision, Jonas Kubilius, Johan Wagemans, Hans P. Op De Beeck

MODVIS Workshop

The goal of visual processing is to extract information necessary for a variety of tasks, such as grasping objects, navigating in scenes, and recognizing them. While ultimately these tasks might be carried out by separate processing pathways, they nonetheless share a common root in the early and intermediate visual areas. What representations should these areas develop in order to facilitate all of these higher-level tasks? Several distinct ideas have received empirical support in the literature so far: (i) boundary feature detection, such as edge, corner, and curved segment extraction; (ii) second-order feature detection, such as the difference in orientation or …

The Effect Of Stereoscopic (3d) Movies On Psychological And Physiological Experiences, Dawn M. Sarno

Honors Program Theses and Projects

Despite the recent rise in the popularity of 3D entertainment technology, there is surprisingly little research on the psychophysiological experience of watching 3D movies. Previous studies suggest that exposure to stereoscopic (3D) images in training environments (e.g., flight simulators) can cause discomforts including eyestrain and visually induced motion sickness. However, existing research on 3D entertainment has been mixed and has relied primarily on retrospective, non-experimental research designs, which do not allow us to draw clear causal conclusions. The purpose of this study was to examine the psychological and physiological effects of viewing 3D movies using a controlled, manipulated experiment. Eighty-two …

The Short And Long-Term Effects Of Chronic Ketamine During Adolescence On Object Recognition Memory In Rats, William Hardin

Seton Hall University Dissertations and Theses (ETDs)

Prior research has demonstrated that ketamine causes deficits in object recognition and location memory following both acute and chronic administration (Pitsikas & Boultadakis, 2009; Venãncio et al., 2011). Although it is well established that abuse of many different kinds of drugs during the critical developmental period of adolescence can lead to impairments in cognition later in adulthood (Gilpin et al., 2012; Wagner et al., 2010), no research has investigated the effects of chronic ketamine administration during adolescence and its effects on behavior in adulthood. With recent research establishing that chronic ketamine during adolescence produces late-onset alterations in electrophysiology during adulthood …

Retention Across Pedagogies, Rachel Larkin

Senior Honors Projects, 2010-2019

When teaching, many professors try to increase their students’ retention of the information that is taught. Instructors can incorporate active learning, repeated testing, collaborative testing, and/or corrective feedback into traditional forms of teaching (e.g., lecture), or they can combine all of these components and transform their entire course, such as with Team-Based Learning (TBL). The current study compares retention of course material in TBL, lecture, reading, and control conditions in a lab setting. In the first session, students received one teaching method and learned about an article on whether having pets led to lowered blood pressure. During the second session, …

The Effects Of X-Axis Rotation On Data Estimation Accuracy, Catherine Mathers

Senior Honors Projects, 2010-2019

Researchers, pollsters, marketers, and others use graphical displays to reduce the need for wordy, and often unclear, descriptions of their findings. Numerous studies have attempted to determine important graphical attributes that aid readers’ graphical perception. For example, does three-dimensionality (3D) of a graph help readers to accurately assess the graph’s data? The present study is the first to use eye movement data to quantify how 3D graphs, graph type, the use of gridlines, and data positioning affected readers’ perception and accuracy. Participants viewed 24 different graphs while their eye movements were recorded. Time, fixation, and accuracy were recorded for each …

The Relation Of Service Activity To Change In Empathy, Nancy L.C. Windsor

Senior Honors Projects, 2010-2019

The purpose of this study was to explore the relationship between empathy, service, and other variables that have been seen in the past to be possible predictors of empathy and service. Undergraduate and graduate students took a survey measuring their emotional empathy, strength of religious faith, intent to engage in civic action, other predictor variables, and the amount of service each participant engaged in. Pearson’s correlations and independent t tests were run to analyze the relationships between the variables. The intent to engage in civic action measure was highly correlated with both the emotional empathy scale and strength of religious …

Hiv-1 And Cocaine: Motivation And Synaptic Function, Sarah J. Bertrand

Theses and Dissertations

Molecular and behavioral assays were used to examine the effects of HIV-1 on synaptodendritic integrity, motivated behavior and the therapeutic potential of natural isoflavones in ameliorating both synaptodendritic injury in vitro and changes in motivation in vivo. The overarching hypothesis of the present dissertation is twofold: 1. HIV-1 causes a decrease in motivation for sucrose and cocaine and the change in motivational state is driven by compromised synaptic integrity as evaluated by F-actin and DAT function and, 2. Treatment with phytoestrogens will prevent synaptodendritic damage, normalize the internal motivational state of the HIV-1 Tg rat for sucrose and cocaine, and …

Human Factors In High-Altitude Mountaineering, Christopher D. Wickens, John W. Keller, Christopher Shaw

Journal of Human Performance in Extreme Environments

We describe the human performance and cognitive challenges of high altitude mountaineering. The physical (environmental) and internal (health) stresses are first described, followed by the motivational factors that lead people to climb. The statistics of mountaineering accidents in the Himalayas and Alaska are then described. We then present a detailed discussion of the role of decision-making biases in mountaineering mishaps. We conclude by discussing interpersonal factors, adaptation, and training issues.

Paradoxical Interaction Between Ocular Activity, Perception, And Decision Confidence At The Threshold Of Vision, Aaron Schurger

Psychology Faculty Articles and Research

In humans and some other species perceptual decision-making is complemented by the ability to make confidence judgements about the certainty of sensory evidence. While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness …

Biases In Race And Social Desirability Within Jury Simulations, Michelle Hallaran

Honors Program Theses and Projects

This study examined how the defendant’s race and the victim’s social desirability influence sentencing. Participants were randomly assigned to read one of four crime scenarios, featuring either a Black or White defendant or a socially desirable or undesirable victim. For each scenario the defendant’s race was manipulated and participants were shown a picture of either a Black or White male. Data were collected at two different time periods, because of potential influence of media coverage of racial bias in jury decisions. Therefore, the effects of defendant race, victim social desirability, and time period were tested through an experiment using a …

Traumatic Experiences And Cognition: How Do Static And Dynamic Variables Contribute To Current Functioning?, Cathryn Richmond

Masters Theses, 2010-2019

Approximately 25% of children in the United States will witness or experience a traumatic event before age 4, and individuals with a history of trauma, particularly traumatic events in childhood, have a much higher likelihood of developing psychopathology in adulthood. Prior research indicates that the vast majority of individuals with a serious mental illness, particularly those in community mental health centers and psychiatric inpatient settings, have experienced at least one traumatic event in their lifetime. These individuals require special consideration in treatment planning, and a large range of neurodevelopmental and environmental factors must be taken into account when interpreting results …

Teacher Child Interaction Training As A Universal Prevention Program In Preschool And Kindergarten Classrooms, Jessica Rossi

Dissertations, 2014-2019

The current study assessed the effectiveness of Teacher Child Interaction Training (TCIT), an adaptation of Eyberg’s Parent Child Interaction Therapy (PCIT), on teacher and child behaviors in preschool and kindergarten classrooms. The sample included four classrooms in urban, socioeconomically disadvantaged and culturally diverse settings. Two preschool classrooms were included in the first study and one preschool and one kindergarten classroom were included in the second study. Both studies used a concurrent multiple baseline design to evaluate the effects of training and coaching on teacher and child behaviors in the classroom. The intervention focused on the development of a friendly attachment …

The Development Of Character Adaptation System (Cast) Intervention, Lauren Mays

Dissertations, 2014-2019

The primary objective of this dissertation was to explore the feasibility and utility of an individualized intervention derived from a group therapy manual grounded in Henriques’ (2011) Unified Theory of Psychology. This framework serves to translate terminology from different theoretical perspectives and map their overlap and distinctive qualities onto human functioning. This project provides a more directive educational approach to explore whether and how clients can be directed to understand these systems and benefit from them. The second goal was to explore the appropriateness and impact of this manual on a client presentation typically seen in college outpatient treatment. These …

Teachers’ Beliefs And Practices Related To Student Self-Regulation In The Classroom, Marlana L. Webster

Dissertations, 2014-2019

Self-regulation serves as a pivotal skill for children to acquire early in life. Mastery of the skill leads to high academic achievement and increased sense of self-efficacy. Teachers play a major role in developing self-regulation in children. Consequently, the beliefs and practices that teachers hold regarding poor self-regulation (i.e. inattention and impulsivity) are to be understood and taken into account. The Self-Regulation Survey was created to capture teachers’ attributions for inattention and impulsivity along with subsequent chosen interventions in 52 participants. The results indicated that teachers attribute impulsivity to organic factors and family origin to a greater degree than classroom …

The Nature And Etiology Of Religious Certitude: Implications Of The Ei Framework And Beliefs, Events, And Values Inventory, Timothy W. Brearly

Dissertations, 2014-2019

Religious certitude is often associated with conflict between individuals and groups, though the nature of this relationship is still not clear. To further clarify these dynamics, the historical psychology of religion is reviewed and contrasted with current perspectives from social psychology and neuroscience, with an eye towards better understanding the variance within religious expressions and their associated relationships with intergroup conflict. It is hypothesized that religious certainty is related to a difficulty in engaging with contradictory religious perspectives, and that the pull towards certainty is tied to an individual’s unique psychological structure, much of which is developed through the interaction …
