A Case Study: Observations Of Behaviors & Vocalizations In A Captive Asian Elephant (Elephas Maximus) During Quarantine, Alexandra L. Dilley

Theses and Dissertations

Bozie, an Asian elephant (Elephas maximus), was relocated from the Baton Rouge Zoo to Smithsonian’s National Zoo. During a requisite 29-day quarantine period, I recorded Bozie’s stress-related behaviors and the vocalizations she produced when she was alone and with her keepers in free and protected contact.

Investigating The Nest Sanitation Hypothesis In A Rejecter Species: Is Sanitation A Proximate Link, Pre-Adaptation, Or By-Product Of Egg Ejection?, Alec B. Luro

Theses and Dissertations

Nest sanitation, a behavior similar in motor pattern to egg ejection, has been proposed repeatedly as a potential pre-adaptation to foreign egg ejection in avian brood parasites hosts. We found no support for the sanitation hypothesis--therefore we suggest egg ejection may have evolved independently of sanitation.

Eye-Tracking And Corpus-Based Analyses Of Syntax-Semantics Interactions In Complement Coercion, Matthew W. Lowder, Peter C. Gordon

Psychology Faculty Publications

Previous work has shown that the difficulty associated with processing complex semantic expressions is reduced when the critical constituents appear in separate clauses as opposed to when they appear together in the same clause. We investigated this effect further, focusing in particular on complement coercion, in which an event-selecting verb (e.g., began) combines with a complement that represents an entity (e.g., began the memo). Experiment 1 compared reading times for coercion versus control expressions when the critical verb and complement appeared together in a subject-extracted relative clause (SRC) (e.g., The secretary that began/wrote the memo) compared to …

Psychometric Evaluation Of The Offender Coping Self-Efficacy Scale In The Context Of Incarceration And Upon Re-Entry, Minhdan Thuy Ta

Clinical Psychology Dissertations

Incarceration presents unique stressors that affect psychological well-being. Identifying self-efficacy for different types of coping strategies to manage stressors may help treatment teams develop appropriate interventions aimed at reducing recidivism. Consequently, I developed and evaluated the preliminary psychometric properties of the Offender Coping Self-Efficacy Scale (OCSS). An initial pool of 47 items was used to assess inmates’ confidence in their ability to cope with stressors related to incarceration and re-entry. The scale was completed by a sample of inmates (N = 144) who were 18 years or older and serving time at one of two county jails. The majority …

A Cultural Comparison Of Two Facial Inference Studies, Janine Swiney

Symposium Of University Research and Creative Expression (SOURCE)

Two different samples from Pakistan and the United States were asked to infer the emotions and personality traits shown in three facial expressions (angry, sad, happy) of young white females and males in six photographs. The two studies used Amazon.com’s Mechanical Turk (MTurk) to investigate the facial inference process. Each picture was presented for 10 seconds followed by four questions about the individual in the picture. The first question asked participants to identify the emotion shown, from a list of six emotions (anger, disgust, fear, happiness, sadness, surprise). The next three questions consist of condensed sets of the Big Five …

Social Media Use And Self-Esteem In Undergraduate Students, Carly Renee Pineiro

Theses and Dissertations

With technology growing every day, people are using a different form of communication which is social media. Social media is a way that people communicate with family/friends, get information, post photos, etc. It is estimated that the average amount of time spent on this social networking site ranges from thirty minutes to over two hours on a daily basis. The purpose of this study is to explore a correlation between high usage of social media use and lower levels of self-esteem. To test the correlation between social media usage and self-esteem students were asked to participate in an online, anonymous …

The Role Of Work Volition In The Association Between College Students’ Medical Illness Symptomatology And Their Major Satisfaction, Educational Persistence Intentions, And Career Aspirations, Lauren Michele Bouchard

Theses and Dissertations

This thesis reports the results of a study exploring the role of work volition in the relations of health-related symptomatology and perceptions to the short-term career outcomes of major satisfaction, leadership aspirations, educational persistence intentions, and real/ideal career discrepancy. The responses of 366 college students to an online survey revealed that illness perceptions and the number of unhealthy days out of the last 30 were significantly related to work volition. Work volition was significantly related to all four short-term career outcomes. Path analyses showed that work volition was a mediator between unhealthy days and all four short-term career outcomes, which …

Facial Expressions In Generalized Anxiety Disorder, Lauren Noble

Theses and Dissertations

This study found that greater displays of sad facial expressions and body movement are associated with higher self-reported anxiety-related symptoms in those with GAD. In the control group, lower scores on rumination and worry scales are associated with greater displays of fearful facial expressions during the fear video.

An Integrative Model Of Situation Awareness, Andrew Thurston

USF Tampa Graduate Theses and Dissertations

In aviation safety incident reports, lack of situation awareness (SA) is often attributed as the cause of negative safety outcomes, such as accidents. While the predominant model of SA has identified three components of SA, perception, comprehension, and projection, assumptions of their relationships with each other and external criteria are yet tested empirically. Specifically, SA theory suggests comprehension SA fully mediates the relationship between perception and projection SA. Additionally, research on the relationships between individual differences and SA is lacking. The purpose of the current study is to test a comprehensive model of SA which simultaneously examines the described mediation, …

Beauty, Sex, And Death: The Role Of Mortality Salience In Objectification Processes, Kasey Lynn Morris

USF Tampa Graduate Theses and Dissertations

Although much attention has been paid to the consequences of objectification, relatively little research has focused on the question of why women are objectified. From a terror management theory perspective, the association of women with (literal) objects strips them of the qualities that are threatening (on account of mortality concerns). Sexualization, however, underscores women’s animal nature, and this association is problematic in the management of existential anxiety. The current research builds on a distinction between sexual and appearance-focused objectification to identify the existential mechanisms in the motivation to dehumanize, and subsequently harm, women. Consistent with the hypothesis, participants primed with …

Music, Emotion, And Personality Typing: A Look Into Coexisting Relationships, Bradley Darin Thorsen

Theses and Dissertations from 2016

This study was intended to replicate previous research findings on musical preferences as a result of specific personality typing; explore the potential for using musical preferences as predictors of determining personality types; and examine changes in personality and music preference across various demographics. Existing research in the areas of music and personality have provided essential information that leads to understanding motivations and influences for an individual's preference. The current study, utilizing both the Small Test of Musical Preferences (STOMP) and Big Five Inventory (BFI), consisted of a questionnaire completed by undergraduate student volunteers (n = 362) via a campus-wide e-mail …

Laterality Strength Is Linked To Stress Reactivity In Port Jackson Sharks (Heterodontus Portusjacksoni), Evan E. Byrnes, Catarina Vila Pouca, Culum Brown

Laterality Collection

Cerebral lateralization is an evolutionarily deep-rooted trait, ubiquitous among the vertebrates and present even in some invertebrates. Despite the advantages of cerebral lateralization in enhancing cognition and facilitating greater social cohesion, large within population laterality variation exists in many animal species. It is proposed that this variation is maintained due links with inter-individual personality trait differences. Here we explored for lateralization in Port Jackson sharks (Heterodontus portusjacksoni) using T-maze turn and rotational swimming tasks. Additionally, we explored for a link between personality traits, boldness and stress reactivity, and cerebral lateralization. Sharks demonstrated large individual and sex biased laterality …

Anxious Anticipation Of A Social Threat And Its Effect On Time Estimation, Natasha April Tonge

Arts & Sciences Graduate Student Theses and Dissertations

Time perception is a well-studied phenomenon; however, subjective experience of time and its relationship to affective states has received comparatively less attention in the literature (Grondin, 2010). Recently, it was suggested that anticipatory anxiety may also lead to an overestimation effect regarding angry faces in socially anxious individuals (Jusyte et al., 2014). In the present study, participants completed two temporal bisection tasks (TBT) in which they were asked to categorize a stimulus as being of short or long duration. Between the tasks, participants were to present a speech that served to provoke anxiety. In the present study, I aimed to …

Investigating The Effects Of Copy Number Variants On Reading And Language Performance, Alessandro Gialluisi, Alessia Visconti, Erik G. Willcutt, Shelley D. Smith, Bruce F. Pennington, Mario Falchi, John C. Defries, Richard K. Olson, Clyde Francks, Simon E. Fisher

Psychology: Faculty Scholarship

Background

Reading and language skills have overlapping genetic bases, most of which are still unknown. Part of the missing heritability may be caused by copy number variants (CNVs).

Methods

In a dataset of children recruited for a history of reading disability (RD, also known as dyslexia) or attention deficit hyperactivity disorder (ADHD) and their siblings, we investigated the effects of CNVs on reading and language performance. First, we called CNVs with PennCNV using signal intensity data from Illumina OmniExpress arrays (~723,000 probes). Then, we computed the correlation between measures of CNV genomic burden and the first principal component (PC) score …

Rostral Middle Frontal Gyrus Thickness Is Associated With Perceived Stress And Depressive Symptomatology, Lindsay J. Michalski

Arts & Sciences Graduate Student Theses and Dissertations

Elevated stress perception and depression commonly co-occur and have shared genetic and environmental influences, suggesting they may rest upon a common underlying neurobiology. The rostral middle frontal gyrus (RMFG), part of the dorsolateral prefrontal cortex, is critical for executive function, including emotion regulation and working memory. Variability in RMFG cortical thickness has been associated with both depression and stress-related phenotypes, although the directionality of these associations has been inconsistent thus far. The current study examined healthy participants (n=879) who completed the ongoing family-based Human Connectome Project were included in analyses. RMFG cortical thickness was computed from structural magnetic resonance imaging …

The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry

Seton Hall University Dissertations and Theses (ETDs)

The inability to remember events experienced very early in life is referred to as Infantile Amnesia (IA) and has been observed in both humans and animals. Over the years interest in the phenomenon waned, but has recently increased with the discovery of new neurobiological methods to study brain function (e.g., Callaghan, Li & Richardson, 2014). The neurobiological mechanism behind IA has yet to be determined, but several innovative theories have been developed with these new research methods. The neurogenesis hypothesis theorizes that increased neurogenesis during early development disrupts previously established memories. The hippocampus, an area that mediates both the memory …

A Phenomenological Examination Of Expatriate Families During Their Transitions To Living In A Foreign Country, Kwamia N. Rawls

Seton Hall University Dissertations and Theses (ETDs)

For hundreds of years, people have traveled across land and sea for various employment opportunities. In the past, the majority of these moves have been taken by the worker alone, leaving their family members, spouse and children, behind in their country of origin. With the advancement of technology, the relative convenience of global transportation, and higher paying overseas jobs, many families are now able to accompany the member whose work has been posted over seas. Experiences of expatriate workers and their families, as they transition to living in a foreign country, is an important area of interest for companies, professionals, …

Education About The Adverse Health Effects Of Recreational Marijuana: The Role Of Type Of Persuasion And Source, Dina Mattern

Seton Hall University Dissertations and Theses (ETDs)

In recent years, efforts have been made to legalize cannabis based on increasing research supporting medical benefits and the assumption, albeit questionable, that this is a safe drug. Statistics from the National Institute on Drug Abuse (NIDA) demonstrate a sharp increase in users, especially among the youth population (2014). This is problematic because smoking marijuana during the teenage years has been shown to have possible adverse effects, such as despondency and potential complications in cognitive development. (Crane et al., 2012) This current study aims to explore effective ways to educate the public on the adverse health effects of recreational marijuana …

Do Rats Consume Ethanol To Regulate A Negative Emotion Induced By A Successive Negative Contrast Procedure?, Andrew Dieterich

Seton Hall University Dissertations and Theses (ETDs)

According to the self-medication hypothesis, individuals may consume drugs or alcohol, or engage in other behaviors in order to reduce a negative emotional state (Khantzian, 1985; Gross, 2013; Crum et al., 2013). Rats experiencing a negative state induced by various stressors (Bertholomey et al., 2010), or a decrease or loss in reward value of a sucrose solution (Manzo et al., 2015; Manzo et al., 2014) demonstrate increased consumption of alcohol. I used successive (SNC) and anticipatory negative contrast (ANC) procedures to further examine this hypothesis and the previous findings (Manzo et al., 2015), that rats increase consumption and preference for …

Virtual V1sion: A Collaborative Coding Project, Cheryl Olman

MODVIS Workshop

Virtual V1sion is a new idea for fostering modeling collaborations and data sharing. While still in its infancy, the ultimate goal is a website that hosts repositories for (1) interchangeable model elements, (2) datasets that can be fit/predicted by those models, and (3) educational modules that explain the background for both the models and the datasets. The scope of the modeling is limited to predictions of V1 responses, although not all computations represented by model elements in Virtual V1sion are required to be V1-intrinsic: a goal of the project is to provide a framework in which predictions for modulation by …

A Neural Circuit For Visual Information Spreading, Gregory Francis

MODVIS Workshop

I describe a neural circuit made of integrate-and-fire neurons that instantiates a mechanism for the spreading of visual information. The circuit is simple and operates at a reasonable time scale with reasonable parameter values. Slight alterations to the anatomy allow the circuit to spread information across surfaces (constrained by the surface boundaries) as for brightness and color effects or across a group/object (as for some attention effects).

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2^nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

Differential Styles Of Emotional Reactivity And Antisocial Behavior Relative To Post-Traumatic Stress Disorder Symptom Expression In Detained Youth, Molly A. Miller

LSU New Orleans Theses and Dissertations

This study sought to explore whether PTSD symptoms in detained adolescents were differentially related to high and low patterns of emotional reactivity, as determined based on callous-unemotional (CU) traits and emotion dysregulation. Analyses revealed four distinct groups based on these criteria: a low/no trauma control group with few PTSD symptoms, and three groups whose PTSD symptoms were distinguished by symptoms of emotional numbing. The study sought to determine whether these profiles were related to distinct patterns of aggression and delinquency. Results revealed that the low/no PTSD symptom group exhibited the least aggression and delinquency. Further, results indicated that higher CU …

Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders

LSU New Orleans Theses and Dissertations

Stress and anxiety negatively impact the working memory system by competing for executive resources. Broad memory deficits have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing children (M = 11.10 years, SD = 2.95). Results indicate reduced post-stress RSA recovery and overall increased levels of cortisol in children with 22q11.2DS. Additionally, anxiety mediated the relationship between 22q11.2DS and visuospatial working memory impairment. However, there was no indication that stress response physiology mediated this association. …

Hormonal Correlates Of P50 Suppression In Socially Anxious Young Adults, Andrea M. Tountas

LSU New Orleans Theses and Dissertations

Ten to 15% of the population is temperamentally shy and have elevated physiological stress responses to novel social situations. Yet, the neural mechanisms underlying this personality trait are not fully understood (Beaton et al., 2009; Schmidt et al., 1997). Efficiently attending to, acting on, and remembering relevant stimuli and filtering out less important information is critical given the sheer volume of sensory and perceptual stimuli the brain is exposed to.

Relevant stimuli that garner attention are remembered and consolidated with existing memories. Stimuli that do not warrant extended attention are ignored or habituated to in a process underpinned by cortical …

Profiles Of The Forms And Functions Of Aggression And Psychosocial Outcomes In Two Distinct Juvenile Offender Populations, Kelli R. Thompson

LSU New Orleans Theses and Dissertations

The current study was designed to explore profiles of reactive and proactive aggression in two distinct juvenile offender populations, in a group of juvenile offenders who have been adjudicated for illegal sexual behavior (n = 138) and in a group of juvenile offenders adjudicated for general delinquent behavior (n = 243). This is the first study of its kind to investigate profiles of aggression in a population of juveniles adjudicated for illegal sexual behavior. Preliminary profile analyses indicated that the two juvenile offender populations had similar profiles of aggression overall. Two step cluster analysis results were generally consistent …

Individual Differences In Adolescents’ Driving Practice During The Learner Stage, Yinan Zhao

LSU New Orleans Theses and Dissertations

The implementation of Graduated Driver Licensing (GDL) policies has reduced the rate of car crashes among adolescents. However, limited research has focused on adolescents’ supervised driving during the learner permit stage of GDL. The study aimed to describe supervised driving practice during the learner permit stage and to test predictors of individual differences in the amount and the quality of supervised driving. 183 adolescents (M age = 16.4 years, 54.1% female) and their parents (84.1% mothers) participated. Adolescents reported driving an average of 25 minutes per day. Adolescents living in single-parent households, with less family income, and with a …

Figure-Ground Organization Using 3d Symmetry, Aaron Michaux, Vijai Jayadevan, Edward Delp, Zygmunt Pizlo

MODVIS Workshop

We present a novel approach to object localization using mirror symmetry as a general purpose and biologically motivated prior. 3D symmetry leads to good segmentation because (i) almost all objects exhibit symmetry, and (ii) configurations of objects are not likely to be symmetric unless they share some additional relationship. Furthermore, psychophysical evidence suggests that the human vision system makes use symmetry in constructing 3D percepts, indicating that symmetry may be important in object localization. No general purpose approach is known for solving 3D symmetry correspondence in 2D camera images, because few invariants exist. Therefore, to test symmetry as a clustering …

The Impact Of A Supportive Feedback Environment On Attitudinal And Performance Outcomes, Amanda Lee Blinebry

Dissertations

While the positive outcomes of feedback in the workplace have been supported in previous research, there is still a lack of theoretical unity explaining how and why feedback may be advantageous. In addition, previous studies examining the effects of feedback have resulted in mixed findings. Two studies were conducted to clarify the conditions for valuable feedback by proposing and empirically testing two models examining relationships between feedback environments and outcomes. The first study examined performance outcomes related to a supportive feedback environment while the second study examined attitudinal outcomes associated with a supportive feedback environment. Results of both studies indicate …
