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 …

Brainwaves, Memory, And Reward, Rebecca Mccune

Dissertations, Theses, and Capstone Projects

The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …

The Effects Of Isolated Affordances On Preschool Counting Improvement When Using A Digital Coloring App, Katherine Papazian

Dissertations, Theses, and Capstone Projects

Counting is an important preschool math skill that is necessary for building a strong foundation in mathematics. Previous research has demonstrated that guided counting activities can improve counting ability in preschoolers and that drawing on paper while learning can deepen processing, but research has not included digital drawing as a potential means of deepening processing while children count. This study developed a novel touch-screen app, which used a guided coloring activity to encourage effective counting skills and serve as a home numeracy tool that could be employed by all parents, including those with math anxiety. To evaluate the benefits of …

Evaluating Neural Networks As Cognitive Models For Learning Quasi-Regularities In Language, Xiaomeng Ma

Dissertations, Theses, and Capstone Projects

Many aspects of language can be categorized as quasi-regular: the relationship between the inputs and outputs is systematic but allows many exceptions. Common domains that contain quasi-regularity include morphological inflection and grapheme-phoneme mapping. How humans process quasi-regularity has been debated for decades. This thesis implemented modern neural network models, transformer models, on two tasks: English past tense inflection and Chinese character naming, to investigate how transformer models perform quasi-regularity tasks. This thesis focuses on investigating to what extent the models' performances can represent human behavior. The results show that the transformers' performance is very similar to human behavior in many …

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 …

Understanding The Relationship Between Working Memory And Long-Term Memory, Kelly Cotton

Dissertations, Theses, and Capstone Projects

How lasting memories are created is a question that has driven much research into human cognition. An area of renewed research interest concerns the relationship between working memory and long-term memory. Recent research has investigated how the processing that occurs while information is held in working memory influences successful long-term memory creation. Both working memory consolidation and maintenance have been identified as critical in long-term retention, but the mechanisms underlying the working memory/long-term memory relationship remain unclear. The present dissertation examined different working memory mechanisms and their impact on long-term memory in a broader context by addressing two questions: 1) …

The Lived Experience Of Using Opiates Among Young Adults, Catherine Mbewe

Dissertations, Theses, and Capstone Projects

The purpose of this research study is to explore the lived experience of using opiates, as described by young adults aged 18 to 25 years. Over the last 2 decades, opioid use disorders (OUDs) and opiate overdose deaths have increased dramatically in the United States. What used to be a problem primarily contained to minority groups in poor inner-city areas is now increasingly common in all races, genders, ages, and classes. There has also been an alarming increase in opiate use—including fentanyl, both legal and illegal—among young adults. While much of the literature has been focused on the opiate use …

A Novel Measure Of Narrative Self-Functioning And Its Role In The Transformative Potential Of Psychedelic Experience Across Clinical And Non-Clinical Participants, Nicole M. Amada

Dissertations, Theses, and Capstone Projects

The eudaimonic field of well-being is founded on the idea that self-knowledge and the realization of one’s potential is at the heart of what it means to strive for well-being. While the “self” is at the core of this perspective, theories derived from this field have yet to incorporate neurocognitive conceptualizations of the self, and account for the collection of self-referential cognitions that influence striving for well-being. Such a theory and measure could fill this theoretical gap and be applied in person centered interventions to capture change in these processes over time. One such intervention utilizes psychedelic experience as a …

Unexpected Arousal Suppresses Memory And Metamemory Predictions During Associative Face-Name Recognition Task, Sameer Sabharwal-Siddiqi

Dissertations, Theses, and Capstone Projects

Successful recognition often depends on probabilistic estimation of memory-signal. Arousal has been shown to offset the influence of heuristic evidence on memory prediction. We conducted three experiments that tested whether arousal also suppresses predictions relevant to memory confidence. Experiments employed associative face-name memory tasks that included retrospective (Experiments 1 and 2) or concurrent (Experiment 3) judgements of confidence. During test, subjects were presented with a masked-affective face on a subset of trials. By timing the masked-affective face to precede a recognition judgement (Experiment 1), we replicated the finding that unexpected arousal offsets the influence of heuristic evidence on expectations of …

Linguistic Abstractions In Children’S Very Early Utterances, Qihui Xu

Dissertations, Theses, and Capstone Projects

How early do children produce multiword utterances? Do children's early utterances reflect abstract syntactic knowledge or are they the result of data-driven learning? We examine this issue through corpus analysis, computational modeling, and adult simulation experiments. Chapter 1 investigates when children start producing multiword utterances; we use corpora to establish the development of multiword utterances and a probabilistic computational model to account for the quantitative change of early multiword utterances. We find that multiword utterances of different lengths appear early in acquisition and increase together, and the length growth pattern can be viewed as a probabilistic and dynamic process.

Retrieval Practice Promotes Learning Of Turkish As A Foreign Language: A Computer-Assisted Language Learning Study, Maya C. Rose

Dissertations, Theses, and Capstone Projects

Adults generally find it difficult to learn a new language, yet exhibit remarkable individual differences in outcomes. Variation in second language (L2) learning is associated with input conditions (Morgan-Short et al., 2010) as well as learners’ aptitude (Dörnyei, 2005). Recent work has demonstrated benefits of retrieval practice in promoting L2 learning of grammatical patterns and vocabulary in both artificial and natural languages (Hopman & MacDonald, 2018; Keppenne et al., 2021). With that said, when retrieval practice is based on oral recall as opposed to a recognition test, it confounds potential benefits of repeated testing (Rowland, 2014) with those associated with …

Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia

Dissertations, Theses, and Capstone Projects

Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …

Virtual Reality Supplement To The Peers Social Skills Intervention For Adolescents With Asd, Kevin Ambrose

Dissertations, Theses, and Capstone Projects

The purpose of this study was to replicate findings of the Program for the Education and Enrichment of Relation Skills (PEERS) parent-assisted social skills training program for a diverse group of adolescents with historical autism spectrum disorder (ASD) diagnoses in an urban locality. Additionally, this study sought to pilot a 3D multi-user virtual environment for adolescent participants and an online learning community for parent coaches; both hypothesized to reinforce the social skills curriculum. A randomized controlled trial of PEERS was completed with 12 adolescents diagnosed with ASD with some participation from their caregivers. Results show that participants who received the …

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, …

Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell

Dissertations, Theses, and Capstone Projects

Successful regulation of fear memories is a fundamental tenet to the exposure-based therapies often employed by mental health professionals for individuals with PTSD, phobias, and other anxiety disorders. Consequently, the efficacy of these treatment methodologies is largely dependent on the strength of the fear memory, as stronger memories are often characterized by an increased resistance to extinction and heightened fear recovery. However, there is little consensus within the scientific community regarding how to effectively maximize fear memory strength in human studies, and the literature exploring the impact of variability in acquisition parameters on memory strength is sparse. Here, we tested …

Individual Differences In Coping With Large Multimodal Conflicts In A Spatial Orientation Paradigm, Cassandra J. Engstrom

Dissertations, Theses, and Capstone Projects

This study examined how humans respond to large 180º disparities between internally generated self-motion cues and external landmarks in a navigation task. Subjects learned the locations of 4 objects in a virtual environment, navigating back to these sites in a testing phase that probed their sense of direction at dead-ends. In select (incongruent) trials, subjects’ virtual rotations were mirrored relative to their physical turns, forcing them to navigate along separate virtual and physical trajectories. On these trials, subjects were either instructed to navigate using their memory of the required turn sequence (proprioceptive instructions) or the external environment (visual …

Semantic Network Activation Contributes To The Relationship Between Mood And Inhibition, James S. Maniscalco

Dissertations, Theses, and Capstone Projects

Prior research has identified several relationships between mood and executive functions. Very broadly, these findings generally suggest that positive moods are associated with enhanced cognitive performance, particularly in working memory and learning. However, recent studies note that there are some instances in which negative moods may benefit select executive skills, such as those involved in divided attention and inhibition. In sum, these findings indicate that positive moods favor top-down, heuristic, or relational processing, whereas negative trait moods favor bottom-up, detail-oriented processing. However, a clear mechanism by which these effects occur has yet to be identified.

The most compelling theories that …

Pilot Study Of The Effects Of Mobile Based Resonant Frequency Breathing On Cognitive Performance In Healthy Young Adults With Elevated Stress, Daniel Saldana

Dissertations, Theses, and Capstone Projects

Objective: Prior research has shown a bidirectional relationship between breathing, emotions, behavior, and cognitive functions thought to be mediated by the autonomic nervous system (ANS). Studies have shown that deep or diaphragmatic breathing interventions are associated with improved affect and decreased stress levels, but little attention has been paid to the effects of breathing training on cognition. The few studies that have looked at this have shown improved attention, memory, and executive functioning as a result of breathing interventions. While suggestive of positive benefits, these studies used control groups that are either inactive or inappropriate for determining their respective mechanisms …

The Influence Of Prosecutorial Overcharging On Defendant And Defense Attorney Plea Decision Making: Documenting And Debiasing The Anchoring Effect, Stephanie Aurora Cardenas

Dissertations, Theses, and Capstone Projects

Strategic overcharging, a practice that some prosecutors readily employ to threaten defendants with excessively severe sentences, undermines the Sixth Amendment right to trial by coercing defendants to plead guilty rather than face penalties disproportionate to their alleged misconduct. Legal scholars and psychologists have long suggested that strategic overcharging may elicit powerful anchoring effects that bias defendants’, but not attorneys’ evaluations, of the plea offer. The current research sought to examine (a) the extent to which mock defendants and legal professionals were susceptible to the anchoring bias, (b) elucidate the mechanism underlying susceptibility to the anchoring effect in plea contexts, and …

The Effect Of Anticipatory Anxiety On Fear Extinction Learning, Daniela C. Echeverria

Dissertations, Theses, and Capstone Projects

Adaptive regulation of fear is dependent on successful fear extinction learning; therefore, investigating factors that both enhance and diminish fear extinction learning is a critical line of research. In the present study, we induce mild anticipatory anxiety during fear extinction learning in an attempt to modulate how participants extinguish fear memory. In the experiment, we apply a classic three-day fear learning protocol to both control participants (N = 20) and an experimental group (N = 20) with fear acquisition, fear extinction, and fear recovery phases; each phase is separated by a period of 24 hours and we use a skin …

Examining The Transient Neural Dynamics Underlying Working Memory Maintenance For Complex Visual Stimuli, Chelsea Reichert Plaska

Dissertations, Theses, and Capstone Projects

Working memory (WM) is the temporary storage of information to accomplish a future goal. The WM delay period is the time after encoding but before retrieval when information is being maintained, typically in the absence of relevant stimuli. Understanding how the brain supports maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM research is how information is stored during this delay period. One …

Rethinking Thinking About Thinking: Against A Pedagogical Imperative To Cultivate Metacognitive Skills, Lauren R. Alpert

Dissertations, Theses, and Capstone Projects

In summaries of “best practices” for pedagogy, one typically encounters enthusiastic advocacy for metacognition. Some researchers assert that the body of evidence supplied by decades of education studies indicates a clear pedagogical imperative: that if one wants their students to learn well, one must implement teaching practices that cultivate students’ metacognitive skills.

In this dissertation, I counter that education research does not impose such a mandate upon instructors. We lack sufficient and reliable evidence from studies that use the appropriate research design to validate the efficacy of metacognitive skill-building interventions (not just evaluate their relationship to learning outcomes). I argue …

From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood

Dissertations, Theses, and Capstone Projects

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Mobile Cognitive Training For The Cognitive Symptoms Of Depression In Young Adults: A Double-Blind, Randomized Pilot Study With Active Control, Alice Grinberg

Dissertations, Theses, and Capstone Projects

Background: Depression is associated with a broad range of cognitive symptoms, including reduced attention, verbal learning and memory, executive functioning (EF), and processing speed (PS). Computerized cognitive training (CCT) has been shown to ameliorate the cognitive symptoms of depression. Younger adults, in particular, are understood to benefit more from CCT than older adults due to their greater capacity for neuroplasticity. However, several issues remain unclear about the effectiveness of CCT: (1) whether the benefits of CCT are driven by the specific content or by non-specific factors, such as engagement, motivation, novelty, and expectancy, which have been inadequately controlled in prior …

The Cognitive Thalamus: Source Analysis Of Scene Working Memory Delay Activity, Bernard A. Gomes

Dissertations, Theses, and Capstone Projects

Working Memory represents a limited-capacity store for maintaining information and manipulating the store's contents over a short period for the guidance of goal-directed behavior. Working Memory is an essential component of executive functions that are intricately associated with the prefrontal cortex (PFC). The PFC has been implicated in maintaining task-related information online for brief periods in the absence of relevant information. This active maintenance phase is called the delay period that occurs between encoding and retrieval of the stimulus. Previous studies have attempted to understand the relationship between working memory and the PFC, especially during the delay or maintenance phase …

Working Memory Training: Cognitive And Linguistic Implications In Adult English Language Learners, Deepti Wadhera

Dissertations, Theses, and Capstone Projects

This study used a cognitive training paradigm to explore whether the same mechanisms of working memory underly conflict resolution in non-verbal and verbal domains in adult English language learners.The association between an individual’s Working Memory (WM) performance and their success in skills such as interference control, decision-making and language processing has been repeatedly highlighted by researchers in cognitive psychology and linguistic fields. Particularly, acquisition and use of a second language is one life experience in which WM ability seems valuable. However, when this association is put to the test in studies that train participants’ WM and measure transfer of these …

Bilingual Reading Fluency And Prediction: Heritage Language Versus Second Language, Olga Parshina

Dissertations, Theses, and Capstone Projects

The thesis presents the first comparative investigation of reading fluency and factors that affect it by examining eye movements in reading by Heritage Speakers (HSs) and L2 learners of Russian. The eye movements of bilingual participants are compared to two control groups, monolingual adults and monolingual children. Following the introductory Chapter 1, in Chapter 2 we present the study that establishes basic eye-movement characteristics in reading for Heritage Speakers and L2 learners in connection to proficiency and linguistics factors of word length and frequency. Contrary to our predictions, we found that all eye-movement characteristics of high-proficiency HSs are different from …

The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides

Dissertations, Theses, and Capstone Projects

Cognitive control describes a set of mechanisms that guide behavior towards a goal (Cohen, 2017). The successful execution of cognitive control is essential for effective learning, information processing, problem solving, and academic achievement (Visu-Petra et al., 2011). The Expected Value of Control framework (EVC; Shenhav et al., 2013) suggests that control carries an inherent cost, which is weighed against the potential benefits of expending it. This cost-benefit analysis determines the direction and intensity that a goal is pursued. Importantly, motivation plays a role in this cost-benefit analysis and may function as the factor that offsets the cost of control expenditure …

Applying A Metacognitive Framework In The Neuropsychological Assessment Of Subjective Cognitive Decline And Mild Cognitive Impairment, Susan Y. Chi

Dissertations, Theses, and Capstone Projects

The characterization of the earliest stages of Alzheimer's disease (AD) is a topic of major research interest because it is critical for early diagnosis and emerging interventions. Metamemory, or knowledge about memory, including awareness of one’s own memory functions, has been investigated in AD especially in relation to how impairment in memory and executive functions contribute to unawareness of cognitive deficits, termed anosognosia. Previous research, however, has not systematically investigated metamemory functioning in older adults with prodromal dementia conditions. Therefore, we investigated metamemory accuracy in cognitively healthy older adults (HC) and those with subjective cognitive decline but intact neuropsychological test …

Beyond Exposure: Markers Of English Proficiency In School-Aged French–English Bilinguals, Erin Quirk

Dissertations, Theses, and Capstone Projects

Bilingual children show more variation in their language development than monolingual children, a fact that has been linked to their experience with their languages. Bilingual language experience also varies more than monolingual children's, both in terms of how much they hear the language spoken around them (exposure) and how much they speak the language themselves (production). This dissertation investigates the following aspects of the relationship between bilinguals’ language experience and development which are not well-understood: how children’s language production relates to their proficiency in that language, how children’s language exposure relates to receptive versus expressive and lexical versus grammatical skill, …
