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 …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

The Effects Of Acute Exercise On Retrieval Induced Forgetting, Walter Simpson

Honors Theses

Retrieval Induced Forgetting (RIF) is a type of active forgetting that may play beneficial and detrimental roles in long-term memory. The benefit of the retrieval of certain information is that information will become more readily available following subsequent retrieval; a concept termed the retrieval practice effect (RP). The detrimental effect of RIF may be that, upon the subsequent recall of certain information, related information may be inhibited from recall. The effects and mechanisms of RIF have remained a topic of debate among neuroscientists, psychologists, and other related scholars. The goal of this study was to evaluate the effects of acute …

Everyday Memory In People With Down Syndrome, Yingying Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman

Honors Thesis

Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …

The Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes

Masters Theses & Specialist Projects

The ability of 16 younger adults to visually perceive distances in depth was evaluated within three environmental contexts (indoors in the dark, indoors in the light, and outdoors). The observers' task was to bisect an 8m distance interval in all contexts using both monocular and binocular vision. In the outdoor environment (a natural grassy field), the observers' judgments indicated perceptual compression of farther distances similar to that obtained in many previous studies. In the indoor lighted environment (a 10.2 x 9.6m laboratory room), the observers' judgments were consistent with perceptual expansion of farther distances. Finally, there was a beneficial effect …

Neurocognitive Interactions Between Anticipatory Anxiety And Memory Encoding, Felicia M. Chaisson

LSU Master's Theses

Although acute anxiety has been shown to improve encoding of threat-relevant information, its effects on threat-neutral information are less understood. Recent research suggests that anxiety can impair subsequent recall for neutral words, particularly following practice with the recall task. Here we use event-related potentials (ERPs) to test the notion that anxiety specifically disrupts the implementation of encoding strategies—such as elaborative encoding—that tend to develop with practice. ERPs were recorded as participants studied two sets of neutral words, one of which was presented in a stressful context using the threat-of-shock paradigm (threat block), and the other in a non-threatening context (safe …

How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel

Department of Psychology Faculty Scholarship and Creative Works

Drawing upon multidimensional theories of intelligence, the current paper evaluates if the Geneva Emotional Competence Test (GECo) fits within a higher-order intelligence space and if emotional intelligence (EI) branches predict distinct criteria related to adjustment and motivation. Using a combination of classical and S-1 bifactor models, we find that (a) a first-order oblique and bifactor model provide excellent and comparably fitting representation of an EI structure with self-regulatory skills operating independent of general ability, (b) residualized EI abilities uniquely predict criteria over general cognitive ability as referenced by fluid intelligence, and (c) emotion recognition and regulation incrementally predict grade point …

An Evaluation Of An Application Designed For The Ipad® To Measure Stimulus Overselectivity For Future Use In Autism Research, Adrienne A. Fitzer

Dissertations, Theses, and Capstone Projects

Twenty-three college students participated in two studies evaluating an application designed to measure stimulus overselectivity in pictures depicting facial affect. We analyzed whether this application worked as designed by evaluating whether it could provide a robust analysis of the types of errors users make (e.g., by matching by the top features, the bottom features, or not by the top or the bottom features), and the extent to which the application worked to decrease selective responding in the event a user was not matching consistently by all features. We also evaluated if participant scores on the Autism Quotient and RAADS-14 could …

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 …

An Evaluation Of Wayfinding Abilities In Adolescent And Young Adult Males With Autism Spectrum Disorder, Yingying Yang, Weijia Li, Dan Huang, Wei He, Yanxi Zhang, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Background

Wayfinding refers to traveling from place to place in the environment. Despite some research headway, it remains unclear whether individuals with Autism Spectrum Disorder (ASD) show strengths, weaknesses, or similarities in wayfinding compared with ability-matched typically developing (TD) controls.

Method

The current study tested 24 individuals with ASD, 24 mental-ability (MA) matched TD (MA-TD) controls, and 24 chronological-age (CA) matched TD (CA-TD) controls. Participants completed a route learning task and a survey learning task, both programmed in virtual environments, and a perspective taking task. Their parents completed questionnaires assessing their children’s everyday wayfinding activities and competence.

Results

Overall, CA-TD …

Critically Evaluating Website Credibility: Factors That Influence Perceptions Of Online Mental Health Information, Mikayla Kimery

All Master's Theses

Research on the use of online information has suggested that general users of the internet do not critically evaluate the information they consume. In addition, specific elements of online information, such as the presence of advertisements, has been shown to affect perceptions of that information, resulting in less favorable ratings of websites. In contrast, communication studies have shown that perceptions of the presented information increased favorably when an image of a brain was included even when the actual information was considered insufficient in quality by experts. To date, the combined effects of brain images and advertisements on evaluations of online …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

Electronic Theses and Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Visual Perception And Action In Reaching During Upper Limb Obstacle Avoidance, Nondon Chakraborty

Theses and Dissertations (Comprehensive)

During everyday activities, people reach to specific objects with their hands and avoid obstacles. For people to move successfully through an obstacle gap, it is necessary to be able to accurately perceive the actions that the surroundings afford and adjust hand movements accordingly. Reaching behaviours, including planning (perception) and execution (action), depend on visual information. This study aimed to understand and detect the differences between perceptual judgment and actual performance of both hands during a reaching task at the time of obstacle avoidance by using a hand-scaled approach. Participants were young adults (male (n=7) and female (n=10) aged 18 to …

Uncovering The Neural And Behavioral Factors That Underlie Changes In Processing Visual Orientation, Patrick Sadil

Doctoral Dissertations

From moment to moment, the visual environment appears stable; despite prolonged scrutiny, the edge of a desk is not perceived to change. But this apparent stability emerges from perceptual and decisional systems that undergo continuous modulation. In two chapters, I focus on two different kinds of modulation to the processing of visual orientation (i.e., the tilt of an edge). In both chapters, the form of modulation is latent, obscured by standard analyses. To detect those latent changes in perceptual decisions, I develop in this dissertation new statistical tools, at both behavioral and neural levels. In the first chapter, I consider …

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …

Wicked Problems: Depression, Sebastian Wendolowski

English Department: Research for Change - Wicked Problems in Our World

Depression is a disorder that can affect anybody and is the leading cause of disability and disorders in the United States. This year, due to COVID-19, it has hit an all time high, affecting many more people. Suicide rates have been steadily growing across all ages, and this year is at a record high too, showing correlation with depression. There are two types of depression, major depressive disorder and chronic depressive disorder. Diagnosis of depression is typically done physically or through a questionnaire, which is compared into a DSM-5. There are many risk factors for depression and other common mental …

Predictors Of Social Distancing And Mask-Wearing Behavior: Panel Survey In Seven U.S. States, Plamen Nikolov, Andreas Pape, Ozlem Tonguc, Charlotte Williams

Economics Faculty Scholarship

This paper presents preliminary summary results from a longitudinal study of participants in seven U.S. states during the COVID-19 pandemic. In addition to standard socio-economic characteristics, we collect data on various economic preference parameters: time, risk, and social preferences, and risk perception biases. We pay special attention to predictors that are both important drivers of social distancing and are potentially malleable and susceptible to policy levers. We note three important findings: (1) demographic characteristics exert the largest influence on social distancing measures and mask-wearing, (2) we show that individual risk perception and cognitive biases exert a critical role in influencing …

Previous Experiences Drive Attention, Sunghyun Kim

LSU Doctoral Dissertations

Traditionally, the allocation of attention was understood within goal-driven and stimulus-driven factors. However, the traditional approach cannot fully account for the mechanism of attentional orienting. Instead, a growing body of evidence shows that previous search experiences, irrelevant to both goal-driven and stimulus-driven factors, influence attentional allocation. For example, when contexts predict information of targets, the contexts guide attention toward the stimuli having the information predicted by the contexts: contextual cueing. In addition, more valuable stimuli attract more attention: value-driven attentional capture. However, two critical issues are present. First, contextual cueing has been found largely when the contexts and the target …

Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell

Electronic Theses, Projects, and Dissertations

As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …

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.

An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell

Graduate Theses and Dissertations

Emotion regulation and sleep have been identified as mechanisms that may be involved in the development and maintenance of many mental health disorders. However, there has been little research into the relation between sleep and emotion regulation. To address this gap in knowledge, a novel study was conducted. We hypothesized that sleep deprived individuals would demonstrate less approach behavior toward a negatively valenced stimulus, as well as increased self-reported avoidance, compared to a control group. To test this, a randomized controlled experiment using a behavioral measure of approach and a self-report measure of avoidance was conducted. Fifty-two healthy individuals ages …

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref

Dissertations and Theses

In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …

The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …

You’Re The Boss: The Stereotype Content Model As A Predictive Behavioral Tool In Résumé Evaluation Processes, Caylin M. Faria

Honors Program Theses and Projects

Extensive literature has confirmed that hiring discrimination is a persistent problem; less research has focused on the social cognitive mechanisms of prejudicial hiring and its effects on résumé evaluations. The present study evaluated how stereotyped evaluations of minority candidates could be predicted with the Stereotype Content Model (SCM) dimensions of warmth and competence. No published research has demonstrated how SCM group ratings may predict evaluations of individuals and their qualifications for employment. Participants evaluated two résumés for each of five listed job positions and completed a survey packet. One résumé in each pair suggested membership in a minority group: Muslim, …

Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo

Electronic Thesis and Dissertation Repository

Everyday listening often occurs in the presence of background noise. Listeners with normal hearing can often successfully segregate competing sounds from the signal of interest. To do this, listeners exploit a variety of cues to facilitate the separation of simultaneous sounds into separate sources, and group sequential sounds into intelligible speech streams. One of the cues that has been shown to be an effective facilitator of speech intelligibility is familiarity with a talker’s voice. A recent study by Johnsrude et al. (2013) measured speech intelligibility of a naturally familiar voice (i.e., that of a long-term spouse) and showed a …

How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian

Graduate Theses and Dissertations

Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …

Hating Evil: Understanding The Role Of Evil In Interpersonal Hate, Carmen Merrick

Graduate Theses and Dissertations

Research has demonstrated that hate is a protective emotional response to perceived evil, yet the dimensions by which people perceive evil have not been clearly identified. Research has also indicated that it is evil to feel hate, which presents an interesting paradox: if hate protects us from evil, then how can it be evil to feel hate? The present research attempts to identify the dimensions of evil and elucidate the relationship between hate and evil by comparing it to the relationship between dislike and evil. Study 1 tested how participants identified evil in third person scenarios. As predicted, evil was …
