Narcissism And Eyewitness Identification, Haley M. Hearn

Graduate Theses and Dissertations (2019 - present)

According to the Innocence Project, 69% of individuals exonerated by DNA evidence were initially found guilty due to an eyewitness misidentification (Innocence Project, n.d.-a). A way that investigators attempt to prevent misidentification is by assessing how confident eyewitnesses are in their identifications. There is a large body of research suggesting that these confidence estimates can, in many instances, operate as reliable barometers of accuracy. However, what if an eyewitness is overconfident? Narcissism is a personality trait characterized by overconfidence. If a narcissistic eyewitness reports confidence in their identification of a suspect, should this report be trusted? Two studies were conducted …

The Evolution Of Self-Awareness In Conscious Organisms, Robert A. Dielenberg

Journal of Conscious Evolution

Self-awareness in conscious organisms remains an enduring puzzle for philosophers and neuroscientists. This paper proposes a tripartite evolutionary model tracing its emergence through three sequential types: the sensory self (primitive egocentric, valence-tagged awareness of sensory states), the bodily self (external objectification of the body as a distinct entity, evidenced by mirror self-recognition in select species), and the cognitive self (internal objectification of the mind enabling recursive self-transformation). Adopting a monist framework, the model treats consciousness as the biological substrate of delayed neural apperception (the “Delayed Present”), within which selves emerge as increasingly sophisticated models. It distinguishes non-human metacognition—implicit, online regulation—from …

Grief As Slip: (How Little I Show) An Exploration In Clay, When Words Are Not Enough, Michelle A. Smith

Masters Theses, 2020-current

Grief as Slip (how little I show) implies that even as we acknowledge our mortality and the fleeting nature of life, we still only reveal a fraction of our true selves or our deeper realities. The ceramic artwork in this exhibition carries and conveys a journey through the present and remembered emotions of the artists’ personal narrative. By juxtaposing the tactile nature of clay with the ethereal quality of human experience, Smith contemplates the profound interplay between material transformation and emotional resilience. The exhibition’s intent is to translate the essence of complex emotional states into abstracted forms so they can …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

The Role Of The Individual In Animal Collectives, Tanya T. Shoot

Theses and Dissertations (Comprehensive)

Animals form groups for a variety of reasons, primarily as a way to increase access to food, mates, and safety. An important attribute of these groups is their personality composition. Personality is defined as repeatable traits over time and context, and has been found across multiple taxa. Traits have been found to be heritable, and are thus a unit for natural selection to act upon. Having a heterogeneous group may be beneficial for survival in a changing environment. The question of how the personality composition of the group affects group behaviour has rarely been asked in the field of animal …

Effects Of A Psychological Stressor On Methamphetamine Seeking In Rats., Kayla B. Cox

Psychology ETDs

Although methamphetamine abuse and fatality rates are on the rise in the United States, there are currently no FDA approved drugs to treat methamphetamine use disorder (MUD). To better understand factors contributing to addiction, researchers have designed various rodent models of stress including the use of footshock, social defeat and maternal separation, however, these models involve physical or early life stress exposure and thus are less translatable to human psychological stress. The present study implemented predatory odors as a model of psychological stress and examined whether chronic exposure to these stressors enhanced subsequent vulnerability to a subthreshold dose of methamphetamine. …

Withdrawal From Voluntary Oral Methamphetamine Reveals Female Specific Susceptibilities To Behavioral Deficits And Neurochemical Perpetuators Of Neurotoxicity And Drug Seeking Behavior, Nicoletta K. Memos

Dissertations, Theses, and Capstone Projects

MA is a potent, highly addictive psychomotor stimulant known to produce neurotoxic effects on the brain leading to neurological impairments^1-6 characterized by neurodegeneration of dopaminergic fibers, cell bodies and pathways, as well as brain regions such as the hippocampus, frontal cortex, and midbrain^1,5.

In MA addiction, women are more vulnerable to the behavioral and cognitive effects of MA compared to men. Adult human literature reveals gender differences in usage patterns and women demonstrate increased vulnerability to the neurotoxic effects and health effects of MA use. Women begin drug use at an earlier age, escalate drug use quicker, …

Differential Neural Correlates Underlying Different Cognitive Control Strategies And Their Relationship With The Barratt Impulsiveness Scale, Carroll Bentley

Psychological Science Undergraduate Honors Theses

Impulsivity is defined as a rapid unplanned action to a stimulus, where the person does not consider the consequences of their actions (Moeller et al., 2001). Various measurement techniques exist in the study of impulsivity and include self-report, behavioral and physiological measures. This breadth of measurement techniques affords researchers the opportunity to understand what is likely a multifaceted nature of this construct. Previous literature shows mixed results between the relationship of the three measures. The present study seeks to add clarity between the three different modalities of measuring impulsivity. To address this relationship, an undergraduate sample (n = 171) completed …

Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley

LSU Doctoral Dissertations

Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …

Unresolved Issues Of Behavioral Analysis In Invertebrates, Charles I. Abramson, Paco Calvo

Animal Sentience

Crump et al. (2022) provide a framework for determining the presence of sentience in organisms. Their target article is interesting and thought-provoking, but it does not consider the many unresolved issues related to behavioral analysis – especially when it concerns invertebrates. We feel that no real progress can be made until such fundamental issues as the need for a consistent definition of conditioning phenomena, the lack of a generally accepted behavioral taxonomy, and the use of cognitive terms to explain invertebrate behavior are examined critically.

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 …

The Combined Influences Of Race, Sexuality, And Gender On Perceptions Of Sexual Harassment, Courtney House

Honors Theses

The current research examines the perceptions of sexual harassment based on the influence of the victim’s gender, and the race of both the victim and the perpetrator, and perceiver’s feminist beliefs. By using vignettes (a brief description of an event), we manipulated a) the gender of the victim (man or woman), b) the race of the victim (POC or white), and c) the race of the perpetrator (POC or white). Our hypotheses were as follows: a) vignettes depicting same-sex harassment will be less in line with the definition of sexual harassment; b) vignettes portraying the victim as a woman of …

Analysis Of A Rough-Toothed Dolphin (Steno Bredanensis) Introduction In A Human Care Setting, Lindsey Johnson

Dissertations

Rough-toothed dolphins are a rarely studied species of cetaceans found in temperate and tropical waters throughout the world. These dolphins live in fission-fusion societies and are highly social, swimming in tightly-packed and highly synchronized subgroups consisting of 2-10 individuals. The current study documents the introduction of a stranded calf into an existing population of six rough-toothed dolphins living in a human care setting. Specifically, recordings of vocal and non-vocal behaviors were analyzed across the four phases of the study: baseline, day of introduction, post-introduction, and follow-up. Whistles, a vocal signal associated with social contexts, increased from baseline to post-introduction phases …

Everyday Memory In People With Down Syndrome, Yingying Jennifer 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 …

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 …

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

College of Graduate Studies: Theses & 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 …

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.

The Academic Success And Beyond-Academic Wellbeing Of High Functioning Autistic Boys: A Policy-Professional Care-School-Parent Ecological Perspective, Evelyn Sauceda

Electronic Theses and Dissertations

High Functioning Autistic (HFA) boys have significant social, emotional, and cognitive difficulties and unique cognitive abilities that require special support from stakeholders in their ecology (policy makers, care providers, schools, and parents). The quality of such support and its ecological integration are of poor quality. The purpose of this study was to report on the perceptions of parents of HFA boys about their children’s academic and beyond-academic experiences as understood within a policy-care provider-school-parent ecological framework. This study contributes to the limited ecological literature on the topic. This exploratory, qualitative, phenomenological, non-experimental, and cross-sectional research study used a non-probability, purposive, …

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 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 …

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan

Theses and Dissertations

The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside of its …

Spatio-Temporal Distribution Of Negative Emotions In New York City After A Natural Disaster As Seen In Social Media, Oliver Gruebner, Sarah R. Lowe, Martin Sykora, Ketan Shankardass, Sv Subramanian, Sandro Galea

Department of Psychology Faculty Scholarship and Creative Works

Disasters have substantial consequences for population mental health. We used Twitter to (1) extract negative emotions indicating discomfort in New York City (NYC) before, during, and after Superstorm Sandy in 2012. We further aimed to (2) identify whether pre- or peri-disaster discomfort were associated with peri- or post-disaster discomfort, respectively, and to (3) assess geographic variation in discomfort across NYC census tracts over time. Our sample consisted of 1,018,140 geo-located tweets that were analyzed with an advanced sentiment analysis called ”Extracting the Meaning Of Terse Information in a Visualization of Emotion” (EMOTIVE). We calculated discomfort rates for 2137 NYC census …

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard …

Identifying The Social Contexts Present For Mouthing Behaviors In Bottlenose Dolphins (Tursiops Truncatus), Erin E. Frick

Dissertations

Much of the research on dolphin communication has focused on the acoustic signals produced in a variety of social contexts. Although acoustic signals are undoubtedly an important aspect of dolphin communication systems, dolphin communication is multifaceted and multimodal (e.g., postural, visual and tactile signals, acoustic cues). The present study examined behaviors that involve the mouth (i.e., mouthing behaviors) in a group of captive dolphins using 2,696 minutes of underwater acoustic and video recordings collected from 2010 – 2014. Target behaviors are described as primarily visual (e.g., open-mouth display), both visual and acoustic (e.g., jaw claps), and tactile (e.g., mouthing, biting). …

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …

Mechanisms Of Navigation In Fiddler Crabs: An Analysis Of Allocentric And Egocentric Contributions, Stephen G. Volz

Dissertations, Theses, and Capstone Projects

Navigation in biological systems is a complex task-set that involves learning processes and may include constructing representations of features of their environment. Across the animal kingdom, different learning mechanisms have evolved to similar spatial problems. The extent to which mechanisms are conserved across taxa are an important research area that can guide our understanding of the cognitive dimensions of navigation. Recent studies of mammals, birds, and arthropods has found that these animals often attend to multiple forms of sensory cues, and to either integrate the solutions generated by these cues, or at times prefer one form of cue over another. …

The Effects Of Pre-Trial Event Stimulus Properties On Timing In The Peak Interval Procedure, Daniel A. Garces

Dissertations, Theses, and Capstone Projects

In the peak interval procedure, intruded conditioned stimuli produce shifts in peak/middle time towards later values, regardless of whether these stimuli are presented prior to or during the timing signal. Although the effects of during-trial stimulus properties—temporal location, duration, and salience—have been previously reported, no research exists on how before-trial stimulus properties influence the extent of shifts in middle time. In the present study, we manipulated within subjects both the temporal location and type (i.e., cue alone, response-independent reinforcer alone, or cue and response-contingent reinforcer together) of the pre-trial event. An individual-trial analysis suggested that the type of stimulus event …

Using Conditioned Place Preference To Investigate Changes In The Rewarding Effects Of Running And Eating Following Activity-Based Anorexia, Daniella Plaksiy

Theses and Dissertations

We used conditioned place preference to investigate whether activity-based anorexia would enhance the rewarding effects of running, causing running to be more rewarding than eating. We found that food restricted mice showed a clear preference for the food-associated chamber, and a subset of activity-based anorexia mice preferred the wheel-associated chamber.
