The Neural Correlates Of Bodily Self-Consciousness In Virtual Worlds, Evan A. Owens

Dissertations, Theses, and Capstone Projects

Bodily Self-Consciousness (BSC) is the cumulative integration of multiple sensory modalities that contribute to our sense of self. Sensory modalities, which include proprioception, vestibulation, vision, and touch are updated dynamically to map the specific, local representation of ourselves in space. BSC is closely associated with bottom-up and top-down aspects of consciousness. Recently, virtual- and augmented-reality technology have been used to explore perceptions of BSC. These recent achievements are partly attributed to advances in modern technology, and partly due to the rise of virtual and augmented reality markets. Virtual reality head-mounted displays can alter aspects of perception and consciousness unlike ever …

Attenuated Typicality Effect In Category-Based Inferences: Implications For Autism Spectrum Disorder, Janani Rajagopalan

Dissertations, Theses, and Capstone Projects

Individuals diagnosed with Autism Spectrum Disorder (ASD) often encounter challenges in assimilating atypical exemplars into their categorical prototypes, a cognitive hurdle that can impact their interpretative and integrative capacities. Addressing this problem, the present research sought to develop a robust methodological approach to reduce the effect of this disparity. We examined the elements embedded within the category's internal structure, with the intention of experimentally attenuating the pronounced typicality effect, which is often exaggerated in ASD.

Across four experiments, the thesis investigated the cognitive and neural underpinnings that shape the access to the typicality gradient intrinsic to a category's structure. The …

The Effects Of Equine-Assisted Activities On Execution Function In Children Aged 7–8 Years: A Randomized Controlled Trial, Xiaodong Cheng, Kexin Zhen, Yongzhao Fan, Qian Tang, Hao Wu

Faculty, Staff and Student Publications

BACKGROUND: This study examines the effects of equine-assisted activity (EAA) training on executive functioning (EF) (inhibitory control, working memory, and cognitive flexibility) in children aged 7-8 years.

METHODS: Twenty-Four healthy children aged 7-8 years with a 1:1 ratio of boys to girls were randomly divided into EAA group (EAAG) or control group (CG). The subjects in EAAG were trained for 12 weeks, and CG participated in normal daily activities. All subjects conducted the Flanker, 1-Back, and More-odd shifting tasks at rest and recorded the average reaction times (RTs) and accuracy data of each task.

RESULTS: After 12 weeks of EAA …

Tiktok Use, Flow, And Addictive Behaviors, Santiago Vigil

McNair Summer Research Program

Abstract

TikTok’s design exploits sensory preferences through continuous scrolling, providing a seamless infinite amount of content. Therefore, I hypothesized that TikTok creates a flow state where people are immersed in the app and may lead to addiction-like symptoms. TikTok use may also be associated with boredom proneness and anxiety. Via a self-report survey, participants indicated their use of social media apps, answered items measuring their psychological flow state on TikTok and Instagram (as a comparison), reported the frequency of behaviors indicating symptoms of addiction, and rated their self-esteem, boredom proneness, and general anxiety. Results showed 7 of the 9 flow …

The Effects Of Covid-19 On Cognition In The Pediatric Population, Mia Ramirez, Hope Mccarroll, Lisa Griggs-Stapleton

Summer 2023 Virtual OTD Capstone Symposium

Coronavirus disease or COVID-19, is an infectious disease caused by the SARS-CoV-2 virus. COVID-19 can affect adults and children by causing long-term symptoms such as difficulty concentrating, anxiety, depression, long-term breathing problems, and even heart complications. Children represent about 19% of all reported COVID-19 cases since the pandemic first began. Children also can have trouble concentrating, which can impact their ability to attend school and do their daily activities that require concentration, such as dressing, showering, and social participation. Cognitive deficits due to COVID-19 can impact the pediatric population as they may have decreased occupational performance in desired occupations, such …

The Influence Of Premium Finished Paper Packaging On Consumer Behavior, Sahil Bhayani

All Theses

Companies face the challenge of determining the return on investment of premium paper packaging features, such as substrate thickness and finishing options. If companies can better understand how consumers perceive “premium,” they could channel their focus on specific design elements and maximize their returns (Dwivedi & Nayeem, 2018). Touch is a critical factor in driving consumer behavior and purchase decisions and influencing trust between brands and consumers (Krishna et al. 2017). While previous studies have explored the impact of design elements like size, shape, color, and font on consumer behavior, this research investigates the influence of touch, substrate, print finishes …

Youthful Offenders Sentencing Trends In Pennsylvania, Monika Nwajei

All Theses

The overwhelming majority of existing literature on the effects of age on judicial sentence decision-making focuses on juveniles (ages 18 and below) and older adults. This paper focuses on offenders between the ages of 18-29, who fall legally outside the definition of juvenile, yet do not have the full brain development or clinical maturity of an adult to provide knowledge of sentencing outcomes for different populations and a well-rounded review and critique of judicial sentence decision-making (Johnson, Blum, & Giedd, 2009). Using a series of logistic regression analyses on the Pennsylvania Commission Sentencing (PCS) data from 2001 to 2018, I …

Voluntary Action And Conscious Intention, Jake Gavenas

Computational and Data Sciences (PhD) Dissertations

Traditional experimental methodology in neuroscience involves comparing responses to different stimuli to make inferences about the human brain. However, human volition entails making decisions and acting in a manner that is underdetermined by the external environment. Investigations of the neuronal basis of volition have led to new controversies regarding the existence of free will, and offer potential directions for medical treatments of disorders such as addiction, akinetic mutism, and locked-in syndrome. However, because volition experiments leave aspects of responses “up to” participants, neuroscientists must utilize computational techniques such as modeling, simulation, and advanced analyses to progress our understanding of human …

Allograft Anterior Cruciate Ligament Reconstruction Fails At A Greater Rate In Patients Younger Than 34 Years, Camryn B. Petit, Jed A. Diekfuss, Shayla M. Warren, Kim D. Barber Foss, Melanie Valencia, Staci M. Thomas, Erich Petushek, Spero G. Karas, Kyle E. Hammond, Mathew W. Pombo, Sameh A. Labib, Timothy S. Maughon, Bryan J. Whitfield, Gregory D. Myer, John W. Xerogeanes, Joseph D. Lamplot

Michigan Tech Publications, Part 1

Purpose: The purposes of this study were to characterize the secondary anterior cruciate ligament (ACL) injury rates after primary allograft anterior cruciate ligament reconstruction (ACLR) and to identify the age cut-score at which the risk of allograft failure decreases. Methods: All patients who underwent primary ACLR within a single orthopaedic department between January 2005 and April 2020 were contacted at a minimum of 2 years post-ACLR to complete a survey regarding complications experienced post-surgery, activity level, and perceptions of knee health. Patients were excluded for incidence of previous ACLR (ipsilateral or contralateral) and/or age younger than 14 years. Relative proportions …

Avoiding Anthropomoralism, Julian Friedland

Between the Species

The Montreal Declaration on Animal Exploitation, which has been endorsed by hundreds of influential academic ethicists, calls for establishing a vegan economy by banning what it refers to as all unnecessary animal suffering, including fishing. It does so by appeal to the moral principle of equal consideration of comparable interests. I argue that this principle is misapplied by discounting morally relevant cognitive capacities of self-conscious and volitional personhood as distinguished from merely sentient non-personhood. I describe it as a kind of anthropomorphizing moralism which I call anthropomoralism, defined as the tendency to project morally relevant characteristics of personhood onto merely …

The Effects Of Exercise On The Mental Wellness Of Children (Ages 3-6), Reem Farhat

McNair Research Journal SJSU

When it comes to mental health, young children are often not researched and their tantrums or mood swings are not taken seriously, when in reality these small behavioral issues could be pointing to a larger issue. Children are the most overlooked when it comes to mental health diagnosis and treatment, unless the child begins to display extreme behavior (Philpott et al., 2019). However, preventative mental health care is arguably more pragmatic and less taboo than diagnosis and treatment. While there is research to support the use of exercise in mental wellness, there is still not enough done within the children …

Increasing The Value Of Xai For Users: A Psychological Perspective, Robert R. Hoffman, Timothy Miller, Gary Klein, Shane T. Mueller, William J. Clancey

Michigan Tech Publications, Part 1

This paper summarizes the psychological insights and related design challenges that have emerged in the field of Explainable AI (XAI). This summary is organized as a set of principles, some of which have recently been instantiated in XAI research. The primary aspects of implementation to which the principles refer are the design and evaluation stages of XAI system development, that is, principles concerning the design of explanations and the design of experiments for evaluating the performance of XAI systems. The principles can serve as guidance, to ensure that AI systems are human-centered and effectively assist people in solving difficult problems.

Dualism And Psychosemantics: Holography And Pansematism In Early Buddhist Philosophy, Federico Divino

Comparative Philosophy

In the Indian philosophical debate, the relationship between the structure of knowledge and external reality has been a persistent issue. This debate has been particularly prominent in Buddhism, as evidenced by the earliest Buddhist attestations in the Pāli canon, where reality is described as a perceptual defection. The world (loka) is perceived through cognition (citta), and the theme of designation (paññatti) is central to the analysis of the Abhidhamma. Buddhism can be viewed as navigating between nominalism and cognitive normativism, as it deconstructs language, which is seen as an obfuscating element that separates the subject from the world. In this …

Self-Beliefs, Transactive Memory Systems, And Collective Identification In Teams: Articulating The Socio-Cognitive Underpinnings Of Cohumain, Gabriela Cuconato

Student Scholarship

Socio-cognitive theory conceptualizes individual contributors as both enactors of cognitive processes and targets of a social context's determinative influences. The present research investigates how contributors’ metacognition or self-beliefs, combine with others’ views of themselves to inform collective team states related to learning about other agents (i.e., transactive memory systems) and forming social attachments with other agents (i.e., collective team identification), both important teamwork states that have implications for team collective intelligence. We test the predictions in a longitudinal study with 78 teams. Additionally, we provide interview data from industry experts in human–artificial intelligence teams. Our findings contribute to an emerging …

Hippocampal Volume And The Detection Of Mild Cognitive Impairment In An Older Adult Population: Assessing Performance On Cognitive Screeners Administered In-Person And Electronically, Kristen Fabrizi

Dissertations

The present study investigated how performance on in-person and electronic neuropsychological assessment measures predicted subcortical hippocampal volume and cognitive decline consistent with mild cognitive impairment. It was hypothesized that the Montreal Cognitive Assessment would display better predictive strength than the Cogstate Brief Battery when evaluating subcortical hippocampal volume measured via structural magnetic resonance imaging. It was further hypothesized that the Montreal Cognitive Assessment would be more sensitive to predicting group membership to the diagnostic classification of mild cognitive impairment compared to the Cogstate Brief Battery. The sample included 445 older adult participants selected from the Alzheimer’s Disease Neuroimaging Initiative 3. …

Weakly Supervised Spatial Relation Extraction From Radiology Reports, Surabhi Datta, Kirk Roberts

Faculty, Staff and Student Publications

OBJECTIVE: Weak supervision holds significant promise to improve clinical natural language processing by leveraging domain resources and expertise instead of large manually annotated datasets alone. Here, our objective is to evaluate a weak supervision approach to extract spatial information from radiology reports.

MATERIALS AND METHODS: Our weak supervision approach is based on data programming that uses rules (or labeling functions) relying on domain-specific dictionaries and radiology language characteristics to generate weak labels. The labels correspond to different spatial relations that are critical to understanding radiology reports. These weak labels are then used to fine-tune a pretrained Bidirectional Encoder Representations from …

Architectural And Heritage Experience Through Playful Learning (An Interdisciplinary And Exploratory Action Research Focused On The Egyptian Context), Atheer Ahmed Salama

Theses and Dissertations

“The lack of awareness of the value of heritage and the lack of opportunities to engage in preserving and safeguarding heritage in the public sphere not only puts the heritage in risk of being irremediably lost. It also impoverishes the younger generation’s sense of identity and belonging within its respective socio-cultural continuum, and thus limits its ability to engage and contribute meaningfully to society at large” (UNESCO, 2021). With conducting this research, the researcher believes that heritage-themed analog games may carve the younger generation’s memory of heritage, allowing them to boost their sense of identity and belonging; thus, widening their …

Using Neural Signals To Investigate Athlete Burnout, Mathew R. Hammerstrom, Thomas D. Ferguson, Hendrik L. Pepler, Anthony Pluta, Gordon Binsted, Olave Krigolson

Journal for Sports Neuroscience

Objective: In the present study, we examined the relationships between athlete burnout, brain function, and self-assessment of performance, and how these relationships can be quantified using mobile electroencephalography (mEEG). Specifically, we performed this study to determine whether mEEG can be utilized as an objective measure of athlete burnout. In addition, we sought to determine whether there was any relationship between athlete burnout and athlete self-assessment of performance while controlling for our neural results.

Methods: We tested these relationships in a sample of high-performance athletes – whereby we had athletes complete an mEEG assessment and also had the athletes complete a …

Say That Again: The Role Of Multimodal Redundancy In Communication And Context, Brandon Javier Dormes

Cognitive Science Senior Theses

With several modes of expression, such as facial expressions, body language, and speech working together to convey meaning, social communication is rich in redundancy. While typically relegated to signal preservation, this study investigates the role of cross-modal redundancies in establishing performance context, focusing on unaided, solo performances. Drawing on information theory, I operationalize redundancy as predictability and use an array of machine learning models to featurize speakers' facial expressions, body poses, movement speeds, acoustic features, and spoken language from 24 TEDTalks and 16 episodes of Comedy Central Stand-Up Presents. This analysis demonstrates that it is possible to distinguish between these …

Epistemic Mentalizing And Causal Cognition Across Agents And Objects, Bryan S. Gonzalez

Dartmouth College Ph.D Dissertations

This dissertation examines mentalizing abilities, causal reasoning, and the interactions thereof. Minds are so much more than false beliefs, yet much of the existing research on mentalizing has placed a disproportionately large emphasis on this one aspect of mental life. The first aim of this dissertation is to examine whether representing others’ knowledge states relies on more fundamentally basic cognitive processes than representations of their mere beliefs. Using a mixture of behavioral and brain measures across five experiments, I find evidence that we can represent others' knowledge quicker and using fewer neural resources than when representing others’ beliefs. To be …

Using The Hands To Learn About The Brain: Testing Action-Based Instruction In Brain Anatomy, Fey Parrill

Faculty Scholarship

Brain anatomy is typically taught using static images. We asked participants to use their own hands to represent the brain and perform gestures during learning. We measured learning via a pretest/postest design. We compared five video trainings in which participants heard similar audio and repeated terminology aloud. Conditions were: (1) Image: Participants saw images of a physical model of the brain. (2) Physical model: Participants saw hands pointing to the physical model. (3) Physical model + action: Participants performed actions on the physical model. (4) Hand model: Participants saw images of hands being used to represent the brain. (5) Hand …

Effects Of Daylight On College Students’ Physical And Mental Well-Being, Sathya Thenappan

Quantitative Social Science Undergraduate Senior Theses

While existing literature predominantly deals with the impact of daylight on adults in general and more specifically at the workplace, less is known about its impact on the college student demographic and daylight exposure levels at college residences. Given its considerable impact on both the physical and mental well-being of individuals, daylight has been used in the treatment of an assortment of diseases from seasonal affective disorder to depression. With college students constituting the majority of today’s people who suffer from mental health issues in society, uncovering the link between daylight exposure and its impact on the physical and mental …

Inferring Personalized Treatment Effect Of Antihypertensives On Alzheimer's Disease Using Deep Learning, Pulakesh Upadhyaya, Yaobin Ling, Luyao Chen, Yejin Kim, Xiaoqian Jiang

Faculty, Staff and Student Publications

Alzheimer's disease (AD) is one of the leading causes of death in the United States, especially among the elderly. Recent studies have shown how hypertension is related to cognitive decline in elderly patients, which in turn leads to increased mortality as well as morbidity. There have been various studies that have looked at the effect of antihypertensive drugs in reducing cognitive decline, and their results have proved inconclusive. However, most of these studies assume the treatment effect is similar for all patients, thus considering only the average treatment effects of antihypertensive drugs. In this paper, we assume that the effect …

Predicting The Risk Of Alzheimer's Disease And Related Dementia In Patients With Mild Cognitive Impairment Using A Semi-Competing Risk Approach, Zhaoyi Chen, Yuchen Yang, Dazheng Zhang, Jingchuan Guo, Yi Guo, Xia Hu, Yong Chen, Jiang Bian

Faculty, Staff and Student Publications

Alzheimer's disease (AD) and AD-related dementias (AD/ADRD) are a group of progressive neurodegenerative diseases. The progression of AD can be conceptualized as a continuum in which patients progress from normal cognition to preclinical AD (i.e., no symptoms but biological changes in the brain) to mild cognitive impairment (MCI) due to AD (i.e., mild symptoms but not interfere with daily activities), followed by increasing severity of dementia due to AD. Early detection and prediction models for the transition of MCI to AD/ADRD are needed, and efforts have been made to build predictions of MCI conversion to AD/ADRD. However, most existing studies …

The Politics Of Expertise And The Articulation Of Authority In Democracy: Cognitive Style And Intelligibility In The Education Of Problem-Solving And Professional Decision-Making In The Domain Of Law, Michael W. Raphael

Dissertations, Theses, and Capstone Projects

Computational complexity refers to the representational aspect of problem-solving. This representational aspect is commonly understood to describe the regularities that organize the definition of the problem-situation, the qualities that designate its difficulty, either in terms of the process of arriving at a definition of the problem or in the process of arriving at a solution. It is for this reason, that it is commonly said that “representational design precedes computational efficacy.” The point of this maxim is to serve as a reminder that an efficient use of resources begins with the design of near decomposability, the specification of the properties …

Association Strength Between Concepts As The Origin Of The "Foreign Language Effect", Emilia Ezrina

Dissertations, Theses, and Capstone Projects

Bilinguals sometimes make decisions in verbal tasks differently in their first (L1) and second (L2) language. This phenomenon is known as the foreign language effect (FLE), and it suggests strong connections between language and cognition. On the one hand, it is possible that L2 “blunts” emotional language. However, the FLE can be observed in non-emotional tasks. Therefore, it is possible that L2 requires more deliberate processing due to increased cognitive load, leading to more rational decisions. The support for each explanation is mixed.

In this thesis we propose looking for a single explanation for all instances of the FLE. After …

Extinction Of Threat Memory Via Reconsolidation Interference: A Behavioral Intervention Meta-Analysis, Chris M. Andrae

Dissertations, Theses, and Capstone Projects

Threat memories are created when an aversive stimulus is paired with other stimuli such that the associated stimuli elicit the same reaction as the unpleasant one. Anxiety disorders are usually treated with exposure to aversive stimuli. Emotional memories can be altered through a process called reconsolidation interference. Consolidated memories are dynamic: reminders of previous experiences prompt the reactivation of a previously-encoded memory; destabilization of the memory opens it to update. While a memory is updating, it is labile. If extinction training occurs during reconsolidation (i.e., shortly after reactivation), the conditioned stimulus will no longer elicit the conditioned response. Thus, previously-encoded …

What You Don’T Know Matters: An Ignorance-Focused Investigation Of Theory Of Mind, Steven M. Shin, Jonathan S. Phillips

Cognitive Science Senior Theses

This project examines the ways in which knowledge, or ignorance, impact healthy adults’ theory of mind (i.e. their considerations of others’ mental states). In a pilot study, and four experiments, an effect is found which supports the hypothesis that knowledge states influence the execution of theory of mind. The present findings suggest that attention is directed differently when participants reason from positions of knowledge, or positions of ignorance, in regard to a task-relevant fact. This project provides a starting point for further research, investigating the rich contextual contributions to the fluent functioning of the ‘theory of mind system.’

Who Am I?: How Natives’ Mental Trauma Develop During Precolonial And Colonial Eras As Seen In Achebe’S Things Fall Apart And Fanon’S The Wretched Of The Earth, Sophia D. Casetta

Pepperdine Journal of Communication Research

Colonialism is a long, brutal process, where natives’ identities are uprooted as colonizers establish their influence in a foreign land. Consequently, through the exploration of the natives’ response to this upheaval throughout the precolonial and colonial eras, the psychological toll that is placed on the colonized is evident. Such mental trauma that is incited is explored in Chinua Achebe’s fictional novel Things Fall Apart, which unveils the slowly lost of the natives’ identities during the precolonial shift, and the non-fiction work of Frantz Fanon, The Wretched of the Earth that details psychological disorders of the colonized due to colonization. …

Bridging Philosophy And Neuroscience: How Behavioral Experiments Inform A Recent Theory Of Animal Consciousness, Qasim Abrar Qureshi

Cognitive Science Senior Theses

Consciousness is a loaded term and can mean many different things to different people. The goal of this paper is to investigate animal consciousness with an emphasis on rats. We investigated different ways of approaching the problem of animal consciousness including neuroscientific and philosophical methods. Next, we examined, a recent theory of animal consciousness in detail and examined neuroscientific evidence to support animals possessing the features described in the theory. The theory posited that consciousness includes five different components: perceptual richness, evaluative richness, self-consciousness, unity, and temporality. After, we discussed the phenomenon of “insight” and how it is similar and …
