Brain-Based Mechanisms Of Behavioral Impairment In Fetal Alcohol Spectrum Disorder (Fasd): The Neuroimaging Biomarkers Of Inhibitory Control, Zinia Pervin

Biomedical Engineering ETDs

The developing brain is highly susceptible to alcohol-induced toxicity, often resulting in long-term deficits in executive function and behavioral regulation. Inhibitory control impairments are among the most prominent deficits observed in Fetal Alcohol Spectrum Disorder (FASD). This study investigated the neural mechanisms of inhibitory dysfunction using a multimodal MEG–DTI approach in 67 children aged 6–8 years (34 with FASD, 33 controls) who performed a Go/No-Go task. Source-level MEG analyses revealed reduced stimulus-locked cortical activation in the anterior cingulate cortex and significant group-by-hemisphere interactions in the superior parietal cortex and cuneus. Time–frequency analyses showed diminished response-locked beta power in the sensory-motor …

Cognition Is Not Content: A Structural Account Of Processing Conditions, Griselda Poe

Publications and Research

Human cognition has been described in terms of content. This description becomes insufficient once artificial systems make output observable apart from subject attribution, intention, and relational context. Under this contrast condition, what becomes visible is a layered structure in which output, reconstruction, evaluation, and termination do not necessarily coincide. The same input may register as complete under one processing condition while remaining unresolved under another. This separability means that content-based description does not merely omit an additional variable: it can mislocate a processing difference as a difference in meaning, personality, intention, ability, or attitude. This is not a proposal for …

From Fog To Function: An Occupational Therapist's Guide To Evaluating And Treating Cancer-Related Cognitive Impairments, Lauren E. Toner

Entry-Level Occupational Therapy Doctorate - Doctoral Capstone Symposium

Cancer – related cognitive impairment (CRCI) is a common side effect of cancer treatment that interferes with cancer survivors’ occupational performance, independence, and quality of life. Despite its high prevalence, CRCI remains under recognized and inconsistently addressed within oncology care. About 70% of individuals diagnosed with cancer report cognitive changes during or after treatment, yet many do not receive treatment. Occupational therapists are clinically trained to evaluate and treat functional cognition, activities of daily activities, instrumental activities of daily living, and client centered goals, positioning them as key providers in addressing CRCI. However, limited occupational therapy specific resources have hindered …

Understanding Social And Cognitive Influences In Medical Students' Learning Processes For Step 1: An Interpretivist Case Study., Ashley Elaine Triplett

Electronic Theses and Dissertations

This qualitative interpretivist case study explores, at a singular institution, medical students’ perspectives on the social and cognitive factors influencing the learning process as students prepare for the Step 1 examination. While prior research regarding medical students Step 1 preparation have focused primarily on wellness, stress, and career outcomes, limited studies have examined medical students' lived experiences to navigate what occurs during the learning process while they prepare for this critical exam. Utilizing a qualitative case study approach, this dissertation draws on fourteen student interviews, seven that passed Step 1 on their first attempt, and seven that failed. Findings reveal …

The Effect Of Birthweight And Gestational Age On Cognitive Function In Midlife: The Bogalusa Heart Study, Eunsun Gill, David J Libon, Soo Jung Kang, Ileana De Anda-Duran, Lydia A Bazzano, Wei Chen, Camilo Fernandez-Alonso, Emily W Harville

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Although the relationships between birthweight, gestational age (GA), and cognitive function (CF) before midlife have been demonstrated, the relationships after midlife and potential racial disparities remain inconclusive. This study examined the association between birthweight, GA, and midlife CF stratified by race.

METHOD: 1,032 subjects from the Bogalusa Heart Study (67% Whites, 33% Blacks, mean age 48.1 ± 5.3 years) were studied. Cognition was assessed with tests measuring verbal episodic memory, working memory, attention, graphomotor information processing speed, and global CF. Each test was standardized by sex and age, then averaged. The global CF was computed by averaging all cognitive …

Does An Impaired Sense Of Smell Make It Harder To Think About Things Like Garlic?, Ishrat N. Khan

Honors Scholar Theses

According to sensorimotor-based (also called "embodied" or "grounded") theories of semantic memory, accessing conceptual knowledge about things involves reactivating—or “simulating”—the sensory and motor experiences that we have had with them. For instance, thinking about things for which olfactory experience is dominant (e.g., garlic or a rose) would involve simulating their smell. However, evidence for olfactory simulation when thinking about "smelly” things is sparse and mixed. We tested smell-impaired (“anosmic”) and control participants (N=130 in the anosmic group and N=190 in the control group) on three tasks (1) Picture-Word Verification, (2) Semantic Property Verification, and (3) Free Recall. We predicted that …

Learning In Nonleafcutting Fungus-Gardening Ants, Elizabeth D. Boshers

Biology Theses

Social complexity influences learning and other cognitive behaviors, but for insects, this influence is not well understood. Delayed rejection is an aversive learning behavior previously studied exclusively in leafcutting ant species, the most socially complex of the fungus-gardening ants. Fungus-gardening ants are unique in that they do not directly consume the material they forage, using it instead as substrate to cultivate a symbiotic fungus on which the ants are obligately dependent. Here, I attempt to induce delayed rejection in several fungus-gardening ant species that exhibit a range of social complexity, then compare the characteristics of delayed rejection behavior among species. …

Spirituality In Place: Assessment Of Spirituality, Place Attachment, And Locus Of Control In College, Chloe Armand

Honors Undergraduate Theses

The intent of this thesis is to explore how spirituality in place shapes college students’ cognition. While spiritual development is recognized as an important aspect of student affairs, its influence on cognitive factors such as locus of control and place attachment remains underexplored. This study investigates the relationship between spirituality, place attachment, and locus of control, as well as students’ perceptions of spiritual design elements on UCF’s campus. To assess these perceptions, a Quality of Place Questionnaire for Spirituality was developed. This instrument aims to measure humanity, sensuality, and sustainability in the built environment. This research uncovers the connections between …

The Power Of Words: Unpacking Language's Role In Educational Inequities, Zara Yokohama, Liz Beccari, Malcolm Jasmin

Symposium Of University Research and Creative Expression (SOURCE)

The language used to describe racial disparities in education may inadvertently influence how we address them. Framing such disparities as “achievement gap” rather than as “inequality in educational outcomes” assumes a deficit thinking mindset, shifting focus from the structural injustices contributing to education disparities to individuals, resulting in decreased prioritization of racial equity (Quinn & Desruisseaux, 2022). We aim to replicate this prioritization effect, specify the language driving the effect, and examine the impact of frames on perceptions of how to achieve racial equity. Participants were randomly assigned to conditions framing racial equity concerns as: a racial achievement gap, racial …

Awareness In The Brain: A Mechanistic And Descriptive Account, Jacob Fried, Roy Pereira

Honors Thesis

An exploration of the different aspects of consciousness and their biological underpinnings, followed by a review of existing theories of awareness in the brain and a critique of the existing research. This paper conducts a review and critique of the contemporary research and finds that no existing theory currently offers an account of awareness in the brain that is both mechanistic and descriptive in nature. Thus, this paper proposes a new theory of the process of awareness in the brain, wherein Attention Schema Theory is considered as the mechanism of awareness and Global Neuronal Workspace Theory as its nature.

Large-Scale Investigation Of White Matter Structural Differences In Bilingual And Monolingual Children: An Adolescent Brain Cognitive Development Data Study, Juliana Ronderos, Jennifer Zuk, Arturo E Hernandez, Kelly A Vaughn

Faculty, Staff and Student Publications

Emerging research has provided valuable insights into the structural characteristics of the bilingual brain from studies of bilingual adults; however, there is a dearth of evidence examining brain structural alterations in childhood associated with the bilingual experience. This study examined the associations between bilingualism and white matter organization in bilingual children compared to monolingual peers leveraging the large-scale data from the Adolescent Brain Cognitive Development (ABCD) Study. Then, 446 bilingual children (ages 9-10) were identified from the participants in the ABCD data and rigorously matched to a group of 446 monolingual peers. Multiple regression models for selected language and cognitive …

Investigating A Potential Protein-Protein Interaction Between Transcription Factor Pax6 And Ribosomal Protein S20 (Rps20), Modupe Oladayo

All Master's Theses

The neocortex is the largest region of mammalian brains and is responsible for the complex cognitive abilities and behaviors of mammals. The neocortex of mature mammals is divided into concise areas, which process sensory information from ears, eyes, and touch receptors, and regulate conscious movement of muscles. The combined graded expressions of several transcription factors over the embryonic neocortical ventricular zone regulates the sizes of these functional areas in the adult neocortex. Although progress has been made in understanding how transcription factors affect neocortical patterning, additional research is required to fully understand the underlying molecular mechanism(s), which will contribute to …

Mrs. Dalloway As A Window For Understanding Life, Kristen Venegas

English (MA) Theses

Virginia Woolf’s Mrs. Dalloway may be dismissed as fiction, and fiction consequently is dismissed as fantasy. However, the novel enables readers to practice an intellectual exercise of meta-awareness that extends beyond the pages and onto real world phenomena. Under a cognitive neuroscience perspective, Mrs. Dalloway is a literary masterpiece due to its hyper- realistic execution of the intimacies of life. Through the narrative style of free-indirect discourse, Woolf illustrates what occurs in the minds of characters as they develop their own perceptions of reality and identity, exposes the fear and inadequacies of mankind’s distress in times of chaos and disorder …

Sex Differences In Stress Reactivity, Brain Morphology, And Oxytocin In The Hypothalamus Of The Gray Short-Tailed Opossum (Monodelphis Domestica), Esperanza I. Zacarias, Daniela Rodriguez, Alexandra Chalons, Sasawan Heingraj, Nicole Altamirano, Joseph Rafac, John L. Vandeberg, Mario Gil

Research Colloquium

Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

What Will Happen If Science Will Develop A Theory Of Consciousness? Negative Ramifications., Sam S.. Rakover

Journal of Conscious Evolution

For a long time, philosophers and scientists have attempted without success to develop a mind-body theory, a consciousness theory (T_c) to explain the exact relation between the mind and the body, a solution which is based on an assumed connection between consciousness and the activity of the neurophysiological processes in the brain. An important concern of the present paper, then, is to address the question of why, despite the great research effort on the subject, no successful T_c has ever been developed. In response, McGinn (1989) proposes that the human being’s cognitive system is not equipped to …

Explicit Rule Learning: A Cognitive Tutorial Method To Train Users Of Artificial Intelligence/Machine Learning Systems, Anne Linja

Dissertations, Master's Theses and Master's Reports

Today’s intelligent software systems, such as Artificial Intelligence/Machine Learning systems, are sophisticated, complicated, sometimes complex systems. In order to effectively interact with these systems, novice users need to have a certain level of understanding. An awareness of a system’s underlying principles, rationale, logic, and goals can enhance the synergistic human-machine interaction. It also benefits the user to know when they can trust the systems’ output, and to discern boundary conditions that might change the output. The purpose of this research is to empirically test the viability of a Cognitive Tutorial approach, called Explicit Rule Learning. Several approaches have been used …

The Influence Of Early Childhood Parental Feeding Behaviors On Self-Regulation & Food Decision-Making In Young Adults, Natasha Singareddy

CMC Senior Theses

This study used data from a diverse set of undergraduates from the Claremont Colleges to examine the relationship between cognitive control (impulsivity and response inhibition) and self-regulatory ability as an indicator of sustained early childhood parental feeding behaviors in adulthood. In addition, the current study explored if early childhood parental feeding behaviors predicted food decision-making in adulthood as a result of perceived taste and nutritional value of food items. It was hypothesized that heightened impulsivity and impaired response inhibition as measures of cognitive control would correlate to poorer self-regulation, in turn reflecting a particular mode of early childhood parental feeding …

The benefit of pharmacological and non-pharmacological treatment of cognitive deficits in this population is unclear. This is an updated version of the original Cochrane Review published in Issue 12, 2014.

OBJECTIVES: To assess the effectiveness of interventions for preventing or ameliorating cognitive deficits in adults treated with cranial irradiation.

SEARCH METHODS: For this review update we searched the Cochrane Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, Embase via Ovid, and PsycInfo via Ovid to 12 …

The Effects Of Floral Attributes And Conspecifics On Bumble Bee Forager Memory, Lucas Lauter, Tiffany Dinh

Undergraduate Research Symposium

What do bees remember about flowers? These memories are important for both bees and flowers. The bees have better foraging success and gain more nectar and pollen from flowers when they remember the most rewarding flower types. More memorable flowers will be visited more frequently, resulting in more successful pollination for the plant. At the same time, bees can also learn about flowers from other bees and may remember this information differently. We are training and testing three floral cues and a single social cue to see how the different types of cues affect their learning and memory of rewarding …

Examining The Cross-Cultural Competence Of United States Christian Missionaries Engaged In Developing Indigenous Leaders: A Mixed Methods Study, Craig W. Goodman

Dissertations

For the past two millennia, missionaries have crossed from one culture to another to bring the Christian message to all cultures of the world. Questions about the effectiveness of these mission efforts have been asked and researched by many; however, one key question remains unanswered: what personal attributes help a person to be more competent at crossing cultures as they interact with people from other cultures? Although cross-cultural competence has been studied in a variety of fields over the past 50 years, the models and assessments used have never been applied to Christian missionaries.

To address this deficiency, this parallel …

Using Ai-Enabled Gaze Tracking System To Understand Comprehension Patterns Of Computer Science Students, Bradley Boswell

College of Graduate Studies: Theses & Dissertations

Academic institutions and instructors lack the ability to accurately assess the moment-to-moment attentiveness of students in classrooms where students’ faces are obscured by computer monitors. This can cause the lectures of Computer Science, Information Technology, or other lab-based courses to be incorrectly-paced, which can lead to students having an overall poorer grasp of the subject material. We propose a system for real-time accurate detection of classroom attentiveness using monitor-mounted webcams and eye trackers, along with a Convolutional Neural Network machine learning model (NiCATS). Through the use of a neural network, we produce an initial attentiveness score based on student webcam …

Metaphors Matter: Top-Down Effects On Anthropomorphism, Hailey Austine Scherer

Dartmouth College Undergraduate Theses

Anthropomorphism, or the attribution of human mental states and characteristics to non-human entities, has been widely demonstrated to be cued automatically by certain bottom-up appearance and behavioral features in machines. In this thesis, I argue that the potential for top-down effects to influence anthropomorphism has so far been underexplored. I motivate and then report the results of a new empirical study suggesting that top-down linguistic cues, including anthropomorphic metaphors, personal pronouns, and other grammatical constructions, increase anthropomorphism of a robot. As robots and other machines become more integrated into human society and our daily lives, more thorough understanding of the …
