Structural Alterations In Cortical And Thalamocortical White Matter Tracts After Recovery From Prefrontal Cortex Lesions In Macaques, Ramina Adam, David J. Schaeffer, Kevin Johnston, Ravi S. Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

Unilateral damage to the frontoparietal network typically impairs saccade target selection within the contralesional visual hemifield. Severity of deficits and the degree of recovery have been associated with widespread network dysfunction, yet it is not clear how these behavioural and functional brain changes relate with the underlying structural white matter tracts. Here, we investigated whether recovery after unilateral prefrontal cortex (PFC) lesions was associated with changes in white matter microstructure across large-scale frontoparietal cortical and thalamocortical networks. Diffusion-weighted imaging was acquired in four male rhesus macaques at pre-lesion, week 1, and week 8-16 post-lesion when target selection deficits largely recovered. …

Hippocampal Functional Activity Following Prenatal Alcohol Exposure, Ryan E. Harvey

Psychology ETDs

Prenatal alcohol exposure (PAE) is among the most common developmental insults to the nervous system and is characterized by spatial memory disruption. There is a pressing need to identify physiological alterations that help explain this memory impairment. The hippocampal (HPC) formation and connected regions are a compelling candidate for this purpose as they are vital for navigation, spatial memory, and memory consolidation. This document is broken up into 3 main parts, a detailed review of the prior literature followed by several experiments. First, It starts out with a comprehensive review on spatial behavioral impairments following PAE and the synaptic & …

The Feeling Mind, Maria Doulatova

Arts & Sciences Graduate Student Theses and Dissertations

According to standard conceptions of agency, our reasons and intentions guide our actions. That is, goal-directed intentions play a key role in practical deliberation, planning, and execution of action. Furthermore, purposeful, goal-directed behavior warrants attributions of responsibility or “reactive attitudes” like resentment, anger, gratitude and forgiveness. However, recent developments of the dual-process theory of mind cast doubt on the empirical adequacy of this picture. While people take themselves to be responding to relevant reasons, they are often bypassed by irrelevant affective or automatic reactions. In this work I go beyond the dual-process theory of mind to offer a mechanistic account …

Understanding The Benefits Of Experiential Learning For Executive Leader Development: A Mixed Methods Approach, Bruce Loveless

Dissertations

This study sought to understand the benefits of using experiential learning methods (such as outdoor activities) for executive leader development from the perspective of senior corporate, government, and nonprofit leaders. Increasingly, executive development programs are embracing “learning by doing” by incorporating experiential activities. Although most programs are influenced by developmental psychology (such as stage theory), this study integrated perspectives from adult, transformative, and experiential learning with common practices in outdoor adventure education into a new conceptual framework for experiential leader development with four types of experiences: intrapersonal, interpersonal, managerial, and environmental. This study fills a gap in research literature regarding …

Cognitive Empathy And Longitudinal Changes In Temporo-Parietal Junction Thickness In Schizophrenia, Derin J. Cobia, Tatiana Karpouzian-Rogers, Julie Petersen, Lei Wang, Vijay A. Mittal, John G. Csernansky, Matthew J. Smith

Faculty Publications

Objective: Deficits in cognitive empathy are well-documented in individuals with schizophrenia and are related to reduced community functioning. The temporoparietal junction (TPJ) is closely linked to cognitive empathy. We compared the relationship between baseline cognitive empathy and changes in TPJ thickness over 24 months between individuals with schizophrenia and healthy controls. Methods: Individuals with schizophrenia (n = 29) and healthy controls (n = 26) completed a cognitive empathy task and underwent structural neuroimaging at baseline and approximately 24 months later. Symmetrized percent change scores were calculated for right and left TPJ, as well as whole-brain volume, and compared between groups. …

A Criminological Analysis Of Notorious Serial Killers In The United States, Hannah E. Booth

Honors Thesis

Serial killing is a phenomenon that both fascinates and scares people. The United States has experienced several notorious serial killers that remain well-known, even years after their crimes. Serial killers are known for having many similar, but also many different traits. Ted Bundy, Dennis Rader, and Aileen Wuornos are some of America's deadliest serial killers, but each has backgrounds and traits that make them unique. This paper will provide an analysis of their psychopathic traits, and a model showing the significance of biological and environmental factors in their lives. Analyzing individual case studies for each killer will explain how their …

Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson

LSU Doctoral Dissertations

Mental imagery is a common component in a range of emotion regulation techniques. However, the effectiveness and neural mechanisms of regulation via mental imagery are underexplored due to a lack of studies targeting mental imagery specifically. This discrepancy results in uncertainty regarding the mechanism of regulation in existing paradigms. Biased competition for attentional resources presents a plausible model by which a mental imagery-based distracter can downregulate response to an emotional stimulus. If visualizing an imagined distracter effectively regulates emotional response, the inclusion of mental imagery components in other techniques represents a potential confound. To address this discrepancy, this dissertation investigates …

The Use Of Animal-Assisted Interventions To Treat Child Victims Of Sexual Abuse, Stephanie Johnston

Counseling Psychology | Master's Theses

This study examines the therapeutic benefits of incorporating dogs into the mental health treatment of child victims of sexual abuse in both formal and informal settings. In 1962, Dr. Boris Levinson began incorporating his dog into therapy sessions with his child clients. He noticed that incorporation of dogs into psychotherapeutic treatment encouraged communication in withdrawn children and published his results in 1969, initiating a widespread interest in animal-assisted therapy (AAT). Other variations of AAT soon followed in the form of animal-assisted activities (AAA). The human-animal bond can be a powerful tool that effectively improves mental health and can play a …

The Medial Temporal Memory System In Down Syndrome: Translating Animal Models Of Hippocampal Compromise, Caron A.C. Clark, Fabian Fernandez, Stella Sakhon, Goffredina Spano, Jamie O. Edgin

Department of Educational Psychology: Faculty Publications

Recent studies have highlighted the dentate gyrus as a region of increased vulnerability in mouse models of Down syndrome (DS). It is unclear to what extent these findings are reflected in the memory profile of people with the condition. We developed a series of novel tasks to probe distinct medial temporal functions in children and young adults with DS, including object, spatial, and temporal order memory. Relative to mental age-matched controls (n=45), individuals with DS (n=28) were unimpaired on subtests involving short-term object or configural recall that was divorced from spatial or temporal contexts. By contrast, …

Examining A Trauma-Based Etiology For Psychosis, David Comer

Educational Specialist, 2020-current

Psychosis has been traditionally viewed through a biological lens, resulting in a narrative of the disorder that does not allow room for therapy. By applying a trauma-informed lens, psychosis can now be thought of as a trauma-based developmental disorder. This impacts how we explain the symptoms of these disorders, and how we view them overall. It also has implications for future treatment, advocacy, and research. This paper examines the bio-psycho-social symptoms of psychosis and offers trauma-informed explanations of the symptoms. Implications for Counselors are examined, as are potential limitations of this current line of research.

The Political Pandemic: Investigating The Relationship Between Political Ideology And Covid-19 Compliance, Allison Moore

Undergraduate Theses

One key to curtailing the health costs of COVID-19 is adherence to social distancing measures. Despite their importance, distancing measures seem to have proved divisive. The present research sought to identify ideological differences in behavioral compliance to distancing measures and to account for the psychological underpinnings of behavioral differences. A first study (April, 2020; N=571) using Amazon’s Mechanical Turk revealed conservatives to be significantly less likely to obey social distancing recommendations than liberals. Differences among conservatives and liberals in adherence to self-reported social distancing practices were significantly mediated by perceived COVID-19 health risk and perceived media accuracy in covering the …

An Evaluation Of Trial-Based Functional Analyses Of Inappropriate Mealtime Behavior, Ashley Andersen

Theses & Dissertations

Functional analyses allow clinicians to develop treatment targeting the variables maintaining a child’s inappropriate mealtime behavior (Bachmeyer et al., 2019). Extended functional analyses can be inefficient, potentially delaying the onset of treatment. Researchers have suggested a trial-based functional analysis can increase assessment efficiency (Saini, Fisher, et al., 2019). This study compared trial-based functional analyses to extended functional analyses to determine the variables maintaining inappropriate mealtime behavior. We compared the efficiency and acceptability and evaluated treatments informed by the analyses. Exact correspondence between analyses was low (29%); however, most treatments indicated by the trial-based functional analyses (71%) resulted in improvements in …

Phase Duration And Resurgence, Sean Smith

Theses & Dissertations

Resurgence, the recurrence of responding due to a worsening of reinforcement conditions for current behavior, is a prevalent form of treatment relapse. Resurgence as Choice in Context predicts that increasing the duration of exposure to reinforcement for target responding during Phase 1 will increase resurgence magnitude, whereas increasing the duration of exposure to reinforcement for alternative responding and extinction for target responding during Phase 2 will decrease resurgence magnitude. We conducted an experiment evaluating these predictions with human participants recruited through Amazon’s Mechanical Turk platform. We varied Phase 1 and Phase 2 durations across four experimental groups. Resurgence as Choice …

An Interpretive Phenomenological Analysis Of Psychotherapists' Experiences Of Vulnerability, Kay Yu Yuan Chai

Electronic Theses and Dissertations

In the service of forging a deep authentic connection that has the power to heal and transform, psychotherapists create and hold space for their patients to show themselves in a deeply vulnerable manner so that they can be known and accepted as they are. At the same time, psychotherapists are also flawed and wounded mortal beings who cannot help but bring their own woundedness, personalities, and limitations into the space, and must negotiate the delicate balance between restraint and expressiveness of their vulnerability. This study is a phenomenological inquiry into how psychotherapists experience their vulnerability given the demands of their …

Canine-Assisted Therapy: Incorporating Canines Into The Therapeutic Experience, Melissa H. Kee

Educational Specialist, 2020-current

Canine-Assisted Therapy (CAT) is a therapeutic practice that has been growing in popularity in recent years but unfortunately has little research to show evidence of effectiveness. This article focuses specifically on the use of canines in therapeutic environments. Use of canines in a therapy setting may be a source of confusion due to the many assistance role that canines can provide, including hearing dogs, mobility assistance dogs, and service dogs. This article provides clarity regarding CAT and includes recommendations for counselors considering the use of dogs in their therapeutic practice.

Comparing The Effects Of Feedback Types On Caregiver Training Of Hispanic Parents, Natasha Cintron

Thesis Projects

The purpose of this study was to identify the preference of feedback types used during parent training with Hispanic caregivers. Knowing the caregiver’s preference of feedback formats allowed for the intervention plan to be designed based on caregiver choice and might enhance the likelihood that the treatment will be carried out as designed by the caregiver. A secondary purpose of the current study was to incorporate cultural values, specifically of Hispanic caregivers in the intervention process. By including cultural components in the intervention, practitioners may improve their cultural competency. Parent training protocols and behavioral skills training (BST) was conducted in …

Voluntary Alcohol Consumption And Sleep Deprivation In Rats, Aesha Khan

Masters Theses, 2020-current

Alcohol is one of the most common psychoactive drugs and has depressant effects on the central nervous system. The vast majority of research on alcohol and sleep commonly indicates chronic alcohol use has a detrimental impact on sleep architecture and homeostasis. However, less research has been conducted investigating the effects of sleep deprivation on alcohol consumption. Our lab's previous studies have looked at a potential bi-directional relationship between sleep and alcohol with promising results. However, there was concern that the method of sleep deprivation may have resulted in stress. The present study examines the effect of sleep deprivation on voluntary …

Memory For A Familiar And Unfamiliar University Logo, Alicia M. Fels

Seton Hall University Dissertations and Theses (ETDs)

Prior research found that memory is fallible and that memory for common objects is poorly encoded (Brady et al., 2008; Nickerson & Adams, 1979). Participants studied one of the logos and recalled both the familiar and unfamiliar logos. Confidence judgments were collected at pre- and post-recall for both logos. Results suggest that recall changed by study condition and logo type, studying before recall, for both the familiar and the unfamiliar logo, improved recall scores. The results also suggest that confidence judgments changed depending on the logo familiarity and time. Confidence decreased from pre- to post-recall for the familiar logo in …

The Effects Of Video Prompting In Completion Of Activities Of Daily Living For Individuals With Traumatic Brain Injury, Jessica Hiter

Masters Theses, 2020-current

According to the Brain Injury Association of America (2020), more than 3.5 million experience acquired brain injuries (ABI) every year in the United States. With improving medical treatment, more individuals are surviving ABI; however, many rehabilitation facilities focus on the physical abilities of the individual rather than regaining independence in daily living skills. Video models have been used with success to teach daily living skills to individuals with developmental and intellectual disabilities, however, little research exists on the use of different types of video models to teach those skills to individuals with traumatic brain injury. The purpose of the present …

The Effect Of Headline Manipulation On Memory And Reasoning, Kathryn R. Hogan

Masters Theses, 2020-current

Decades of research have examined misinformation and memory. Recently, studies have demonstrated that misleading headlines can influence the reader’s memory and inferential reasoning. The current study examines how accurate and misleading headlines differentially affect readers’ memory and inferential reasoning for news articles. College students (N = 138) read three articles on various topics (e.g., solitary confinement, stem cell research, and wildfires) and then took a test to assess memory and inferences related to the article. Contrary to previous studies, there was not a difference in memory between accurate and misleading headline conditions across article types. The effect of a …

Better Together? Effects Of Dyadic Collaboration On Intertemporal Preference, Emily Edgington

Masters Theses, 2020-current

Abstract

Intertemporal choices have been researched extensively in the context of individual choices. However, empirical evidence is absent regarding intertemporal preferences when two individuals collaborate on a choice task. This study aimed to compare the rates of discounting under the condition of dyadic collaboration and individual decisions. Furthermore, this study examined the collaboration sessions in an online video conferencing platform. Results showed a strong, positive correlation between average individual discounting rates and corresponding dyad rates of discounting. The findings of this study should be considered when making intertemporal decisions.

Key Words: delay discounting, group decision-making, online collaboration

Going Against The Flow: Attitudes Related To Interest In Unconventional Menstrual Products, Jessica Sullivan

Honors Program Theses and Projects

The current research examined psychological factors that contribute to interest in unconventional menstrual products, including the commonly studied menstrual cup, but also menstrual underwear, reusable pads, and the menstrual sea sponge. Because unconventional menstrual products are reusable and require cleaning, they are less convenient than conventional menstrual products, requiring more contact with one’s body and menstrual fluids during menstruation. Therefore, people who feel that menstruation is bothersome and disgusting/shameful or people who self-objectify are unlikely to be interested in these products. In contrast, people with more pro-environmental attitudes might find reusable products more appealing. Pro-environmentalism involves significant consideration for others; …

The Therapeutic Benefits Of Attunement Through Lindy Hop, Sarah Trowbridge

Expressive Therapies Capstone Theses

Dance/movement therapy (DMT) was developed as a tool to aide in therapeutic healing. A foundational aspect of DMT is attunement, the emotional/kinesthetic connection between two people that allows for meaningful and healing bonds to emerge. Lindy Hop is a partnered dance that fosters an environment of attunement, as it is accessed both subconsciously and consciously. This research explores Lindy Hop as a possible method of therapeutic treatment. The literature indicates the physiological need for attunement and how safety plays a key role in strengthening senses of self-identity, nervous system development, and worldview. Four experienced Lindy Hoppers were recruited to engage …

"Upskirting,” Homosociality, And Craftmanship: A Thematic Analysis Of Perpetrator And Viewer Interactions, Matthew Hall, Jeff Hearn, Ruth Lewis

psychology

“Upskirting” is the action or practice of surreptitiously taking photographs or videos up a female’s skirt or dress. In the United Kingdom, it is an offense. However, internationally, laws are uneven. Understanding how perpetrators account for their actions becomes an important question. Here, we present the findings of our thematic analysis of posts on the “upskirting” website, The Candid Zone. Our analysis shows that posters and respondents frame this activity as artistic and technical, providing each other with advice and guidance on where and how to get the “best” shots. We conceptualize this form of abuse as homosociality and crafts …

The Role Of Verbal Behavior In Patient-Provider Interactions, Hannah Checkeye

Departmental Honors & Graduate Capstone Projects

The central aspect of any physician-patient interaction is the medical interview. While many studies have investigated these interactions, few have acknowledged the role played by the histories of both patient and physician. The three-term contingency (i.e., antecedent-behavior-consequences; Skinner, 1953) establishes the functional relations between critical events, and is central to the investigation of both verbal and nonverbal behavior. Verbal behavior comprises those actions reinforced through the mediation of others in one’s verbal community. This paper suggests that an analysis of behavior pertaining to the role of verbal behavior in patient-physician interactions more precisely describes relationships between the medical interview and …

Decreases In The Frontal Cortical Areas Following A Developmental Disruption Model Of Schizophrenia, Anna Healy

Honors Program Theses and Projects

Methylazoxmethanol Acetate (MAM) is a toxin that temporarily blocks mitosis in developing embryonic brains. Exposure in rats on embryonic day 17 (E17) selectively targets frontal and hippocampal regions of the brain and produces behavioral and anatomical effects strikingly similar to those seen in human patients with schizophrenia. While previous studies examining these induced neuroanatomical disruptions support E17 MAM exposure as an animal model of schizophrenia, the vast majority focused on male rats. However, there have been a dearth of studies specifically looking at female rats in this model. This is significant since there is evidence of sex differences in the …

Discovering The Wire: Dominance Effects In The Processing Of Polysemes In Sentences, Gwynna Ryan

Honors Theses

Previous research examining the processing of polysemous words presented in neutral sentence contexts has revealed conflicting results. Two different models attempt to explain these divergent patterns. The first predicts that the subordinate sense of an ambiguous word is more difficult to retrieve and process while the second predicts no differences in processing difficulty between the subordinate and dominant senses of ambiguous words. The current study tested the different predictions of these models by presenting sentences with polysemes in a neutral context. Critically, the sense relatedness of the polysemes and the sentence structure were held constant, while the sense frequency of …

Chronic Exercise And Memory Interference, Lisa Vogelgesang

Honors Theses

This online study examined whether chronic exercise is associated with attenuated memory interference. Sixty-three healthy, young adults completed an interference task (AB/AC-paradigm) and self-reported the number of days and minutes a day they engaged in moderate-to-vigorous physical activity. We found that proactive interference (PI), but not retroactive interference (RI), occurred but none of the exercise modalities significantly impacted PI. Future studies should evaluate whether different interference tasks display diverse sensitivities to exercise-induced changes in memory interference. Moreover, other potential modulating factors, such as the duration and intensity of the exercise should be controlled for.

Explanatory Models Of Autism In Nigeria: Exploring Sociocultural Beliefs To Inform Systems Of Care, Gabrielle Udoka Robertson

Honors Theses

Advancements in the diagnosis, understanding, and treatment of individuals with autism spectrum disorder (ASD) have yet to benefit children and families struggling with ASD in Nigeria and other African countries. Not only is there a scarcity of research on ASD in sub- Saharan Africa, but also a lack of mental health and special education services and a lack of understanding of the sociocultural considerations that must inform culturally responsive care. As such, this study explored the sociocultural conceptualizations of autism spectrum disorder (ASD) in Nigeria and how these conceptualizations affect the experiences and care of people with autism. The unique …

A Review Of Behavior Analysis In Education, Devon A. Warner

Capstone Projects

Most education research in applied behavior analysis (ABA) is specific to early learners, which presents significant opportunity to better determine the effectiveness of various instruction methods for college-aged learners (CALs). Within the context of pedagogy, or method of teaching, ABA is the scientific study of the effect of instructional techniques on student behaviors. The available research for college-aged learners is scattered, non-definitive, and has gaps over time. Despite declension over the past half-century, research examining evidence-based practices in education has identified multiple approaches to help instructors manage and improve individual student behaviors and academic performance for CALs. In this review, …
