Femininity And Dateability: A Look At The Perception Of Asian Faces, Grace Yang

Caravel Undergraduate Research Journal

Over the last decade, Asian Americans are the fastest growing ethnic group in the United States (Lam, 2016), and the visibility of Asian influence on popular culture has increased as well (Jin & Yoon, 2017).  As a fast-growing minority community, the Asian community has been relatively overlooked in studies about attraction and the effects of ideals of masculinity. The aim of the current study was to investigate factors that influence the perception of the Asian and non-Asian faces with respect to attractiveness, dateability and masculinity.  The current literature suggests that both Asian men and women are stereotyped to be relatively …

Parenting Style And Academic Success: How Can You Help Your Child Succeed?, Elizabeth A. Weicker

Caravel Undergraduate Research Journal

The goal of this study was to investigate the relationship between the parenting style a college student experienced during childhood and the student’s most recent college GPA. Using survey data collected from undergraduate students throughout the United States, a between-subjects ANOVA was conducted to comparing different parenting styles and mean GPA for those styles. The parenting styles analyzed were authoritative, authoritarian, and permissive. Results indicated significant differences in GPA between parenting styles, with the authoritative parenting style producing the highest college GPA. In addition, an independent samples t-test was conducted to analyze the relationship between student satisfaction with the parenting …

Gesture Development In Infants With Fragile X Syndrome, Killian R. Hughes, Jessica Klusek Ph.D., Ccc-Slp, Carsyn Butler B.A., Jane E. Roberts Ph.D.

Caravel Undergraduate Research Journal

Fragile X syndrome (FXS) is the most common known cause of inherited intellectual disability and also the most common known genetic cause of autism spectrum disorder (ASD; Flenthrope & Brady, 2010). About 60% of males diagnosed with FXS meet criteria for ASD (Klusek et al., 2014). Communication impairments are well documented in FXS and ASD; however, limited research has been done to examine early communication in FXS. Gesture use is one of the earliest signs of intentionality and can serve as an early red flag for atypical communication development, even before delays in spoken language are evident (Crais et al, …

The Relationship Between Child Externalizing Behaviors And Parental Stress In Children With Fragile X Syndrome, Erica Mazur, Majorie Grefer, Jane E. Roberts Phd

Caravel Undergraduate Research Journal

Fragile X syndrome (FXS) is the leading heritable cause for intellectual disabilities and the leading known genetic cause for developmental disorders such as autism spectrum disorders (ASD). The present study examined the relationship between levels of externalizing behaviors in children with FXS and increased parenting stress in parents of children with FXS. Aggressive behaviors and autism severity were examined in 48 male children diagnosed with FXS (range 2-5 years). Parenting stress was examined in 27 of their mothers and 21 of their fathers. Increased severity of autistic behavior was associated with elevated parental stress. Greater levels of parental stress were …

Breaking The Cycle: Implementing Journal-Based Emotional Regulation Workshops At South Carolina’S Department Of Juvenile Justice, Sarah Hobson

Senior Theses

Incarcerated youth experience disproportionately high rates of trauma exposure, estimated at 70% to 90%, which significantly impacts emotional regulation and behavior, keeping them in a cycle of repeated offense and increased recidivism rates (Branson et al., 2017). Despite the prevalence of these psychological needs, juvenile justice systems often lack consistent, trauma-informed programming that addresses the underlying causes of delinquent behavior. This study examines the implementation and impact of a structured, eight-week trauma-informed journaling intervention conducted as a pilot program within the South Carolina Department of Juvenile Justice. This program was implemented among a small cohort of participants at the Juvenile …

How Do People Discern Authenticity From Emotional Expressions, Sewon Oh

Theses and Dissertations

Emotional authenticity is a crucial element in the development and progression of social relationships. However, limited research has comprehensively examined how emotional authenticity perception is shaped by different communication channels, visual attention, and individual differences. This thesis aimed to investigate the emotional authenticity perception from multiple perspectives, including the feasibility of authenticity manipulation, the influence of multimodal cues, and visual attention allocation in assessing authenticity from facial expressions. Findings demonstrated that authenticity could be successfully manipulated by both professional and non-professional actors. Participants differentiated both authenticity and emotion most accurately in audiovisual expressions. The audio channel played an important role …

Stimulation Of The Rostromedial Tegmental Nucleus Induces Long-Lasting Avoidance Behavior, Jacob Ryan Watson

Theses and Dissertations

The role of midbrain dopamine (DA) activity in reward seeking and reinforcement learning is well-documented, contrasting the lesser-understood impact of inhibitory signaling on DAergic activity, especially in the context of aversive learning and avoidance. The rostromedial tegmental nucleus (RMTg) is a GABAergic midbrain structure activated by aversive stimuli and exerts inhibitory influence over ventral tegmental area (VTA) DAergic activity in response to aversive consequences. Stimulation of the RMTg decreases the firing rate of VTA DA neurons and direct inhibition of the RMTg – VTA circuit enhances persistent reward seeking despite aversive consequences, a major criterion of substance use disorder (SUD). …

Beyond The Cell: The Impact Of Parental Incarceration On Children Based On The Factors Of Age, Gender, And Race, Ella M. Zeigler

Senior Theses

Incarceration is a life-changing event. It is humbling to be surrounded by three cement walls and a row of metal bars reaching from the floor to the ceiling. Millions of individuals are impacted by the adverse effects of incarceration, but millions more feel the effect of their incarceration as well. There are obvious negative impacts on those who have personally experienced incarceration, but one of the largest impacts is widely overlooked; one that comes from beyond the cell. This thesis considers the variation in the impact of parental incarceration on children, specifically based on the factors of age, gender and …

Therapeutic Potentials Of The Gut-Brain-Microbiota Axis For Prevention And Treatment Of Motivational Deficits In Ecohiv Infected Rats, Mason T. Rodriguez

Theses and Dissertations

People living with HIV begin to experience gastrointestinal disturbances as early as 6 months after initial infection. Regardless of adherence to combination antiretroviral therapy (cART), the gut microbiome of people living with HIV maintains a state of dysbiosis throughout the rest of their lives, providing potential for a novel target for improving the lives of those living with HIV. The present study investigated the impact EcoHIV and cocaine have on the gut microbiome of F344/N rats. Fecal samples were collected from 20 female and 20 male animals at baseline, following self-administration of cocaine, and following inoculation with EcoHIV or Saline. …

The Effect Of Model Size On The Root Mean Square Error Of Approximation (Rmsea): The Nonnormal Case, Yunhang Yin

Theses and Dissertations

This study aimed to understand the effect of model size on the Root Mean Square Error of Approximation (RMSEA) under nonnormal data. We considered three methods for computing the sample RMSEA and the associated confidence intervals (i.e., the normal theory method [Browne & Cudeck, 1993], the BSL method [Brosseau-Liard, Savalei & Li, 2012], and the Lai method [Lai, 2020]). The performance of the three methods was compared across various model sizes, sample sizes, levels of misspecification, and levels of nonnormality. Results indicated that the normal theory RMSEA should not be used under nonnormal data unless the model size is very …

Neural Correlates Of Audiovisual Integration, Jonathan Conrady

Theses and Dissertations

Successfully integrating multiple streams of information is paired with a variety of behavioral enhancements. Multisensory research over the past few decades has demonstrated the criticality of spatial proximity and stimulus effectiveness. Here, we focused on the temporal aspects and underlying neural activity of frequency-varying, audiovisual stimuli using scalp recorded electroencephalography (EEG). Our set of stimuli was particularly chosen because humans are most sensitive to the auditory sound and visual spatial frequencies that make up speech. Recent work has shown that audiovisual integration effects of low-level, simple stimuli are largest when both modalities fall within, compared to outside of, their respective …

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 …

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 …

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. …

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 …

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 …

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 …

The Effect Of The Difference In The Perception Of Temperature Between Sexes On The Academic Performance Of Chapin High School Students, Tiffany V. Phan

Journal of the South Carolina Academy of Science

Mental performance and mental functions may be negatively affected by decreases in thermal comfort as a result of large differences in temperature. Additionally, females are seen to be less content with room temperatures and actually prefer rooms with higher temperatures in comparison to males. This investigation explored the potential effect that sex plays in thermal perception and the impact it may yield on academic performance within a high school population. It was hypothesized that female students would experience an increase in academic performance as the temperature increased while males would experience the opposite effect. A quasi-experimental approach was used to …

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 …

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 …

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 …

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 …

The Word Frequency Effect In English Second Language Students: An Eye Movement Monitoring Study, Chase Alexandria Rathfoot

Senior Theses

Reading has been the subject of hundreds of thousands of studies. Reading is fundamental skill not only to an individual’s education, but to their socialization and an understanding of the behavior is a rapidly expanding area of research. One of the least understood areas of reading behavior can be found is the growing English Second Language (ESL) population – or those who are learning English after demonstrating competence in their native language. As their native language has its own unique set of properties and is presented in its own unique written form, the influence this language has on their reading …

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 …

When “Right Makes Might”: Moral Superiority And Its Effects On Decision-Making For Others, Emily Shakal

USC Aiken Psychology Theses

Within the psychological literature of morality, little research has been done on the concept of moral superiority. The aim of this study was to determine whether a self-perception of moral superiority led to increased severity of judgment toward social issues and harsher moral action against perpetrators. Participants in the experimental condition were given a moral identity prime prior to all tasks. The results showed that the moral prime was not effective in increasing a sense of moral superiority in comparison to the control condition. Severity of judgment also did not differ between groups. There was no difference between groups on …
