A Psychometric Validation Of The Spanish Translation Of The Coping Inventory In A Latinx Population, Daniela Chavez

Theses and Dissertations

Research efforts to comprehend coping strategies in response to stress within the Latinx/Hispanic community have been limited. The inability to effectively cope with stress can lead to physical and mental health problems in adults. This study aims to test the psychometric properties of the translated version of a recently developed coping assessment, “The Coping Inventory,” to evaluate its validity among Spanish-speaking Latinx individuals. The results indicate that The Coping Inventory demonstrates reliability and validity among this population. These findings can enhance the measurement of coping strategies within the Latinx/Hispanic community, potentially resulting in improved …

Latino Men’S Barriers And Obstacles Towards Treatment Seeking Attitudes, Rebecca Gonzalez

Theses and Dissertations

There is a drastic difference in the number of Latino men utilizing mental healthcare as only 24 percent of Latino men with a severe mental illness ever receive treatment. Previous research has revealed stigma and attitudes are important factors in the help seeking process, but with limited Latino participants. The current study gathered survey data from Latino male university students about their levels of stigma, attitudes towards both tele – health and in person counseling, perceived barriers and benefits, treatment history, and current levels of depression. It was revealed that in contrast to previous studies, Latino men’s social stigma is …

Neural Mechanisms Of Lexical Semantics: Investigating The Roles Of Hubs And Distributed Action-Perception Systems, Nicholas Andrew Riccardi

Theses and Dissertations

Understanding the meaning of words and concepts is vital for communication, forming relationships, and navigating everyday life. Loss of this knowledge through brain damage can have drastic consequences for one’s health and well-being. It is therefore important to learn how this information is organized anatomically in the brain. In this dissertation, I report a series of structural and functional neuroimaging studies in healthy adults and survivors of stroke seeking to understand how lexical semantics are represented. Specifically, I used a variety of tasks to examine the contributions of putative ‘hubs’ and distributed action-perception systems. Results indicated that damage or disruption …

Using Factor Mixture Modeling To Counter Faking, Raul Corrêa Ferraz

Theses and Dissertations

Self-reports (SRs) of typical behavior are often the only existing feasible method to gather data on important drivers of human performance. In applications such as personnel selection, SRs are vulnerable to intentional distortions, often referred to as faking. A review of the literature suggests that so far, the methods proposed to address faking are unsatisfactory. In a recent breakthrough, Pavlov et al. (2019) showed that high-stakes scale scores are best modeled as a function of a) propensity to fake, b) honest scores, and c) the interaction of these two terms. Pavlov et al. did not, however, propose any method to …

Examining The Impact Of Financial Stress On Affect And Eating Behaviors, Ellen Hunt Steele

Theses and Dissertations

Economic pressure and concomitant financial stress have been associated with mental and physical health problems, conflict, and poorer education and employment outcomes. Moreover, financial stress can be seen in specific hardships (e.g., food insecurity) and lead to maladaptive attempts to regulate emotions stemming from financial stressors. Women may be more vulnerable to consequences of food insecurity and attempts to regulate emotions with eating than men. Thus, the current study examined the impact of a randomized financial stress induction on affect and snack food choice while accounting for the influence of food insecurity and gender. Participants included 269 validly responding individuals. …

Cognitive Consequences Of Covid-19 Infection And Quarantine-Induced Social Isolation: Hope For The Young And Mildly Infected, Kristin Nickole Kirchner

Theses and Dissertations

Coronavirus disease 2019 (COVID-19) has infected over 539 million individuals worldwide, and initial research supports the possibility that COVID-19 may damage the central nervous system either directly or indirectly. Neurological signs and noted cognitive deficits observed in even mildly infected patients are a cause for concern for those infected by COVID-19; the effect of social isolation on the central nervous system is also of interest. The present study sought to determine the extent of these potential cognitive deficits in a young and mildly infected sample of college students. Participants completed an extensive survey assessing their experience with COVID-19 and any …

Perfectionism, Alcohol Intoxication, And Deliberate Self-Harm In Men And Women, Lissa N. Mandell

Theses and Dissertations

Previous research has demonstrated associations between deliberate self-harm (DSH) and perfectionism, although most of that research used retrospective self-report measures of DSH, which are prone to various cognitive biases. Although perfectionism has been associated with alcohol abuse, no research has examined how alcohol intoxication may moderate the relation between perfectionism and DSH. The aims of this experimental study were to determine if perfectionism is associated with a laboratory analogue of DSH (the Self-Aggression Paradigm) and examine the role of alcohol intoxication as a potential moderator. Using archival data, blood alcohol content (BAC) was manipulated by randomly assigning participants to reach …

The Impact Of Fluorescent Light On Shelter Dog Behavior (Canis Lupus Familiaris), Kristiina J. Wilson

Theses and Dissertations

Fluorescent lighting is used in a wide variety of applications, however, the flicker that accompanies fluorescent light can be aversive. This thesis examines the impact of fluorescent lighting on the behavior of shelter dogs at New York City’s Animal Care and Control Centers.

Non-Verbal Pride Expressions As A Predictor Of Lgbtq Health, Craig Gilbert

Theses and Dissertations

Pride is a self-conscious, positive emotion that has been assessed in a wide range of populations and with a variety of pre-validated measures. Research has shown that the presence of pride can function as a potential resilience factor against minority based stress and has been linked to increased emotional well being, life satisfaction, and self-esteem. However, a majority of this research relies upon self-report questionnaires as opposed to observational data. To evaluate the predictive power of non-verbal pride behaviors, a group of LGBTQ+ individuals (n=125) were asked during a recorded interview to describe an experience where they felt prideful about …

S-Equol: A Novel Therapeutic For Hiv-1 Induced Gut Dysbiosis, Mason T. Rodriguez

Theses and Dissertations

HIV-1 infection affects approximately 38 million people around the world. The advent of cART has greatly improved the quality of life of infected individuals; however, roughly 50% of these individuals will still experience HIV-1 associated neurocognitive disorders (HAND). Additionally, the gut microbiome has been reported to be dysbiotic in HIV-1 infected individuals, regardless of adherence to cART. Current research has pointed to the gut-brain-microbiota axis as a potential target to treat both cognitive deficits and microbial changes. The present study investigated S-equol (SE) as a potential therapeutic for HAND by modulating the gut microbiome. The study included 21 HIV-1 Tg …

Testing Models Of Context-Dependent Outcome Encoding In Reinforcement Learning, William M. Hayes Iv

Theses and Dissertations

Previous studies of reinforcement learning (RL) have established that choice outcomes are encoded in a context-dependent fashion. Several computational models have been proposed to explain context-dependent encoding, including reference point centering and range adaptation models. The former assumes that outcomes are centered around a running estimate of the average reward in each choice context, while the latter assumes that outcomes are compared to the minimum reward and then scaled by an estimate of the range of outcomes in each choice context. However, there are other computational mechanisms that can explain context dependence in RL. In the present study, a frequency …

Impact Of Number Of Alternatives And Spatial Arrangement On Decoy Effects, Jacob M. Stanley

Theses and Dissertations

The way in which people make decisions is largely guided by the context of the choice set. Choice sets that contain decoy alternatives can result in context effects that violate rational principles of decision making. Most studies on contextual choice manipulate preference among two alternatives in the context of a decoy using three option choice sets. However, many real-world decisions are made among choice sets with many more than three alternatives, such as in online shopping. We tested for attraction and compromise decoy effects in choice sets with varying numbers of alternatives by using a within-subjects preferential grocery shopping task. …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Dreadds Modulation Of Operant Behavior In Male And Female Hiv-1 Transgenic And F344/N Rats, Jessica Illenberger

Theses and Dissertations

The neurobiological processes which determine the choice between 2 (or more) reinforcers are unidentified despite the remarkable benefits which could result from better understanding or control of such processes. Most prominently, reducing choices to pursue drug over non-drug reinforcers could curtail the development or continuation of drug dependence. Likewise, increasing goal-directed behavior in single-schedule and choice settings may alleviate some of the consequences of apathy, a reduction in goal-directed behavior which can occur with neuropathologies including HIV-associated neurocognitive disorders. Dysregulation of the mesolimbic circuit, connecting the ventral tegmental area to the nucleus accumbens, has been implicated in both drug dependence …

Treatment Of Hiv-1 Associated Neurocognitive Disorders Through Mechanisms Of Neurogenesis With 11-Hour Voluntary Running Wheel Exposure, Alex Steiner

Theses and Dissertations

Individuals with HIV-1 taking combined antiretroviral therapy (cART) live longer with less morbidity associated with the infection. The increase in lifespan has created a critical need for the deterrence of HIV-1 associated neurocognitive disorders (HAND) reported in the aging population. Previous reports indicate that the HIV-1 infection may cause impairment in neurogenesis, leading to many of the cognitive deficits seen. The current paper proposes that exercise, as defined by voluntary wheel running, would be a potent inducer of neurogenesis that results in the neuro-restoration of CNS properties and cognitive functioning. Each animal had free access to 11-hour nocturnal wheel-running seven …

Escitalopram Treatment To The Hiv-1 Transgenic Rat: Spine Dynamics, Telomere Quantification And Neurogenesis, Adam Ray Denton

Theses and Dissertations

HIV is a serious viral infection that persists in the brain despite treatment. Approximately half of all seropositive patients will experience some degree of comorbid depression, as well as HIV associated neurocognitive disorders. The present research sought to evaluate the therapeutic efficacy of escitalopram, a selective serotonin reuptake inhibitor in ameliorating neuroanatomical and biochemical markers associated with HIV infection. The central purpose of this research is to characterize the effects of escitalopram treatment upon dendritic spine proliferation in the nucleus accumbens. Previous research has consistently demonstrated impaired synaptodendritic integrity in this region, with underlying mechanisms remaining unclear. A secondary focus …

Response Interruption And Redirection (Rird) As A Treatment For Vocal Stereotypy In Children Who Are Dually Diagnosed With Autism And Down Syndrome, Stacy Taylor

Theses and Dissertations

Individuals who are dually diagnosed with Down Syndrome (DS) and autism spectrum disorders (ASD) frequently engage in vocal stereotypy that can interfere with learning, impede socially appropriate behavior, and disrupt others. Response interruption and redirection (RIRD) is an intervention that blocks and redirects stereotypy to reduce behavior. Studies on RIRD, while varied in their overall approach, have overwhelmingly been shown to be effective in clinical settings for children with ASD. There are few studies that have evaluated this procedure in more natural settings and with other diagnoses. Given that ASD is prevalent in those with DS and that stereotypy is …

Online Training To Improve Job Coaches’ Support Of Minimally Verbal And Nonverbal Adults With Autism Spectrum Disorder, Erin Brooker Lozott

Theses and Dissertations

Although a sizeable percentage of individuals with autism spectrum disorder (ASD) are minimally verbal or nonverbal, there is limited research on how to best support these individuals in employment settings. Job coaches working with this population should receive specialized training in evidence-based practices (EBP) for ASD to ensure optimal outcomes. This study describes the development, implementation, and evaluation of an online training program for job coaches focused on a behavior skills training approach supporting the use of augmentative and alternative communication. Twenty-two job coaches completed the study. Pre- and posttraining measures were used to evaluate knowledge, self-efficacy, and belief systems …

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Application Of The “Idisco” Full-Brain Tissue Clearing Method: A View Of Dopamine And Inflammation In The Hiv-1 Transgenic Rat, Kristin Nickole Kirchner

Theses and Dissertations

The iDISCO (immunolabeling-enabled three-dimensional imaging of solvent-cleared organs) method is a quick, inexpensive, and easily adaptable tissue staining and clearing procedure that allows neuroscientists to study a protein of interest in a whole, unaltered tissue sample. While the iDISCO method was initially tested and validated for mice embryos and brains, the current experiment sought to adapt the method for use in the rat using HIV-1 transgenic (Tg) rat brain tissue. Antibodies for tyrosine hydroxylase and Iba-1 were validated in the HIV-1 Tg rat and in F344/N control rats using iDISCO. Confocal images were taken of tyrosine hydroxylase positive neurons in …

The Behavioral And Neural Effects Of Audiovisual Affective Processing, Chuanji Gao

Theses and Dissertations

In everyday life, we receive affective information from a multisensory environment. What we see and what we hear jointly influence how we feel, think and act. Outstanding questions still remain about the essential behavioral and neural mechanism underlying how we combine visual and auditory affective signals. In this dissertation, I report a series of behavioral, EEG and fMRI experiments addressing this question. I found behaviorally there are congruency, visual dominance, and negativity dominance effects. Using ERPs, I showed that these behavioral effects can map onto different time course in audiovisual affective processing. Time-frequency analyses of EEG data showed that there …

Testing For Differential Attention To Features In Evaluative Conditioning, Christine E. Weber

Theses and Dissertations

One eye tracking and one behavioral experiment examined the possible roles of contingency awareness and attention to stimulus features in evaluative conditioning. These experiments tested whether evaluative conditioning altered the saliency of positive and negative features in consumer products (Study 1) and attitudinal responses to ambivalent pictures (Study 2). Based on the conceptual categorization model, pairing of ambivalent conditioned stimuli with liked or disliked unconditioned stimuli was predicted to result in enhanced attention to affectively congruent features. Study 1 tested this prediction by recording eye movements to determine how attention to features and responses to ambivalent stimuli were altered as …

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

The Maze Of Personality: Latency And Electric Organ Discharge In A Mormyrid Fish, Gnathonemus Petersii Gunther 1862 (Mormyridae, Teleostei), Abbey C. Lipe

Theses and Dissertations

Personality is individual differences in behavior, consistent across contexts. Among Gnathonemus petersii we investigated, we hypothesized that fish could be grouped by: (1) slow/fast maze performance, (2) low/high electric frequencies, (3) correlated latency and frequency. Our first two hypothesis were not supported. Our third hypothesis was partially supported.

Motivational And Physiological Dysregulation Due To Development And Onset Of Obesity Via Melanocortin 4 Receptor +/- Haploinsufficiency, Alex Steiner

Theses and Dissertations

Obesity is one of the leading most health risks around the world, being especially problematic in the United States. A combination of high-fat diets and genetic abnormalities are to blame for the ever-growing number of obese individuals.

Melanocortin 4 receptors are vital for regulating energy expenditure and feeding behaviors; mutations of the receptors have been found to be the leading monogenetic cause of obesity. Using MC4R +/- haploinsufficient rats being fed a range of dietary fat, we investigated the physiological and motivational differences using a locomotor task, an operant task with fixed and progressive ratios, as well as a distraction …

Judging Facial Expressions Of Emotion: Effects Of Gender, Raine Palladino

Theses and Dissertations

This study examined how quickly people recognize happy, neutral or angry emotional expressions on faces that varied in gender presentation and femininity/masculinity of facial features. Facial features influenced judgments of emotion more for women than men. Neutral expressions were more likely seen as angry on a woman’s face.

Building A Statistical Model Of The Drivers Of Self-Presentation, Kathleen Jocoy

Theses and Dissertations

The attempt to maintain a consistently positive public image is known as self-presentation; however, the structure of self-presentation has not been adequately explored. This paper aimed to identify a theory-based model for self-presentation by examining the relationship between personality traits and utilization of self-presentational behaviors. A review of the literature suggested self-presentation would be best modeled with a second order two-factor model with second order factors of Evaluation and Response. The second order factor of Evaluation is expected to explain the first order factors Perceived Anonymity, Sociability, and Communality while the second order factor of response is expected to explain …

Inhibition Of Return In Visual Search: Disentangling Overlapping Contributions With Event-Related Potentials, Allison Michelle Pierce

Theses and Dissertations

Inhibition of return (IOR) refers to the finding that responses to previously attended locations are slower than those to previously unattended locations. Despite over 30 years of research on IOR, there is still no consensus in the field regarding what the underlying mechanism of this effect is. Although IOR is traditionally studied within spatial cueing paradigms, this effect is thought to reflect a mechanism that facilitates efficient visual search. The following studies explored the hypothesis that multiple processes contribute to the IOR effect in visual search and examined whether these are the same processes that result in IOR in cueing …

Behavioral And Voltammetric Analysis Of Chronic Escitalopram Treatment To The Hiv-1 Transgenic Rat: Implications For Comorbid Hiv-1 And Clinical Depression, Adam R. Denton

Theses and Dissertations

HIV-1 infection is a serious condition affecting approximately 37 million individuals. Between 30% and 60% of seropositive individuals will develop symptoms of clinical depression. These individuals are five times more likely to commit suicide than non-seropositive clinically depressed patients. Dysfunction in serotonergic and dopaminergic transmission has consistently been implicated in the pathogenesis of depression. Specifically, dysfunction in the prefrontal cortex and in the nucleus accumbens core region have been shown to be underlying factors in the trajectory of depression. Given these underlying neurological features, the present research employed behavioral testing and electrochemical recording in an attempt to elucidate the therapeutic …
