Retrieval Information From Working Memory: The Output Gating Framework Perspective And Its Underlying Processes, Chen Tiferet-Dweck

Dissertations, Theses, and Capstone Projects

Working memory (WM) keeps information accessible and available for further processing. However, not all the information we maintain in WM is behaviorally relevant at any given moment. To act effectively, we must dynamically control which memory representations are accessed to support ongoing goal-directed behavior. While the mechanisms underlying the selection of single items from WM access are comparatively well-studied, less is known about the principles governing multi-item access. Existing models of WM access imply that selecting multiple items should take longer and be more error-prone than single-item access. Yet, paradoxically, prior studies have shown that retrieving all items in WM …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …

The Interaction Of Multilingualism And Depressed Mood On Cognitive Set-Shifting, Annalise Caviasco

Dissertations, Theses, and Capstone Projects

Although findings are mixed, many researchers believe there are cognitive benefits to multilingualism, a phenomenon dubbed the “bilingual advantage”. Of these apparent benefits, cognitive flexibility, or the ability to shift thinking styles based on the context or specific demands of a certain situation, is thought to be highly relevant. Current literature suggests that one aspect of multilingualism, the practice of “code-switching” between languages throughout their daily lives, is related to increased general cognitive flexibility compared to monolinguals. Another branch of research on cognitive flexibility investigating the role of affect in cognition demonstrates that clinical depression as well as transient negative …

Unveiling The Precision Of Physiological Signals In Prediction Error During Fear Learning: Insights From Associative Strength And Generalized Uncertainty, Haja H. Jallo-Jamboria

Dissertations, Theses, and Capstone Projects

Prediction error (PE) is the discrepancy between expected and actual outcomes. It is a central mechanism in associative learning particularly within fear-conditioning paradigms. Identifying physiological markers of PE in aversive contexts has important implications for refining learning models and enhancing clinical interventions for anxiety-related disorders. This study examined skin conductance response (SCR) as a potential physiological index of PE by analyzing both anticipatory and omission-related responses across multiple learning phases. Participants completed a Pavlovian fear-conditioning paradigm in which two conditioned stimuli (CS+) signaled threat at different reinforcement probabilities: CS+100 (certain threat) and CS+50 (uncertain threat), alongside a non-reinforced safety cue …

Wavelength And Luminance Interaction On Spatio-Temporal Contrast Sensitivity Function, Taylan S. Ergun

Dissertations, Theses, and Capstone Projects

Contrast sensitivity (CS) measures the ability to discriminate objects from their backgrounds under varying conditions(Campbell & Robson, 1968). Contrast sensitivity is important for navigating the real world and operating under different light conditions. The contrast sensitivity function (CSF) reflects how the visual system performs under different conditions. This measure is crucial in assessing the health of the visual system (Chen & Gardner, 2021). CSF contributes to a deeper understanding of how the visual system processes and integrates properties of light to create visual sensation and perception. Human contrast sensitivity depends on the viewing conditions such as field size, luminance, color, …

Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

Characterization Of The Attentional Profile In Women And Girls With A Fragile X Premutation Allele, Shira Russell-Giller

Dissertations, Theses, and Capstone Projects

The fragile X premutation (PM), characterized by 55 to 200 CGG repeats in the FMR1 gene, is associated with diverse clinical outcomes, including cognitive and neuropsychiatric changes. Despite most individuals with a PM presenting without overt clinical symptoms, adults face increased risks for conditions associated with a PM, including higher rates of attention and executive difficulties. This dissertation investigates the developmental trajectory of attention and executive functioning changes in females with a PM using a series of prospective studies employing the Attention Network Test (ANT). Study 1 re-analyzed prior data on sustained attention in women with a PM, revealing significant …

Category Learning Reorganizes Internal Representations Of Visual Artworks, Aishwarya Gurung

Dissertations, Theses, and Capstone Projects

How are categories of art internally represented, and how can we capture those representations systematically? Investigating category learning in the context of complex, multidimensional stimuli like visual artworks presents unique challenges due to their inherent variability and perceptual complexity. Artworks engage multiple cognitive processes and are shaped by both sensory-driven mechanisms and top-down influences like prior knowledge, making them uniquely suited for studying how structured categorical knowledge interacts with perceptual and aesthetic judgments. The present study addresses these questions by utilizing machine-learning tools to construct and implement a two-dimensional similarity space of 400 existing artworks painted by two artists from …

Constructing A Parameterized Stimuli Space Suitable To Induce Controlled Changes In Human And Machine Perceptual Systems, Andrew Frankel

Dissertations, Theses, and Capstone Projects

Traditional computer vision applications focus on objective tasks, such as object detection, classification, or segmentation. Much of human experience is inherently subjective, such as our personal response to artwork. Individualized experiences are challenging to replicate in a controlled laboratory environment, as those experiences depend on the unique history and internal models of the observer. This work presents a technique to construct a 2-dimensional parameterized stimuli space suitable to induce controlled changes in the perceptual systems of both human and machine observers. Our contributions are threefold:

1. Using a balanced dataset of 8,800 fine art images spanning 11 art movements and 88 …

Differential Mechanisms Of Access In Working Memory: Comparing Global And Selective Retrieval, Jade M. Turbides

Dissertations, Theses, and Capstone Projects

Working memory (WM) is essential for numerous cognitive tasks, yet the mechanisms underlying selective access to specific subsets of its contents vs. global, nonselective access remain incompletely understood. Context-specific selection of individual items from WM has been found to be more time-consuming and error-prone than globally accessing all memory contents. This study investigates whether the performance costs of selective WM access arise primarily from demands on item-context binding memory. Previous research has suggested that only selective access relies on memory for item-context bindings whereas global access can solely rely on item memory. Across two experiments, we employed task paradigms that …

Investigating The Impact Of Affect In Suicide-Specific Attentional Biases, Beverlin Rosario-Williams

Dissertations, Theses, and Capstone Projects

Objective: Biased processing of suicide-related information has been implicated in risk of future suicidal thoughts and behaviors. Although previous studies have classified this biased processing, the tasks used to examine these biases cannot definitely specify which attentional processes are related to risk for suicidal thoughts and behaviors. Therefore, via two independent studies, this dissertation sought to distinguish suicide-specific attentional engagement and disengagement biases from other forms of cognitive processing, such as accessibility of suicide-related stimuli and threat bias toward and away from socially threatening stimuli. Additionally, this dissertation investigated under which affective conditions suicide-specific engagement and disengagement biases emerged. …

Helpful Intentions? Impact Of Intentionality On Children's Memory For Forensically-Relevant Information, Ella P. Merriwether

Dissertations, Theses, and Capstone Projects

Rationale: When a child is a witness or victim of a crime, they are often asked a barrage of questions regarding when the crime took place, how many times it occurred, and how the abuse unfolded (Cross & Whitcomb, 2017; Sullivan et al., 2022). These questions can be problematic because they rely on concepts for which children may lack memory or linguistic ability to answer (Fenson et al., 2000; Friedman, 1993). One fundamental element missing from the copious research (e.g., Brubacher et al., 2012; Stolzenberg et al., 2017a; Wylie et al., 2021) on children’s ability to recount forensically-relevant information is …

Challenging Beliefs: Examining The Efficacy Of Corrections For Conspiratorial And Partisan Misinformation, Ava Zwolinski

Dissertations, Theses, and Capstone Projects

The threat of misinformation is widely acknowledged among researchers and laypeople (NORC, 2021). When misinformation coalesces with conspiracy theories, the repercussions can be especially dangerous, sometimes even fatal. Events such as the January 6th insurrection and the Buffalo Tops Supermarket shooting were both, in part, inspired by misleading information and conspiracy theories (Burke, 2022; Dawsey, 2023). While misinformation involving conspiracy theories is recognized as possibly posing a greater threat to correction efforts (Lewandowsky, 2021a), no study has yet experimentally manipulated the presence or absence of conspiratorial elements within misinformation. This dissertation explores whether conspiratorial misinformation is more difficult to correct …

The Beautiful And The Bullshit: Speaker And Listener Mental Representations Influence Bullshit Receptivity, Ryan Tracy

Dissertations, Theses, and Capstone Projects

Bullshit is a topic that has enjoyed an explosion of attention in both cognitive and social psychological research domains. While the picture painted thus far suggests that receptivity to such statements (i.e., perceiving meaning where none exists) hinges upon an individual’s ability to engage in reflective (vs. reflexive) cognitive processing, little attention has been paid to how purveyors of bullshit influence one’s willingness to engage with the message. This is critical to explore, given the status of misinformation in today’s media climate. A critical step involved in determining characteristics of speakers that predict bullshit receptivity is to understand how people …

Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham

Dissertations, Theses, and Capstone Projects

Autism spectrum disorder (ASD) and autistic traits in the general population are associated with differences in sensory processing, particularly within the visual domain. Previous studies examining global (i.e., overall gist) and local (i.e., detail) visual processing in relation to ASD have sometimes yielded contradictory findings yet converge on a common theme: slowed global processing and increased local bias associated with ASD. Despite this consensus, the mechanism underlying these differences remains unclear, whether it be differences in visual attention, higher or lower visual perception, and/or cognitive style. The use of traditional tasks and stimuli may further complicate the understanding of contributing …

Pre-Stimulus Anticipation And Unconscious Fear Learning Disparities In Individuals With Varying Levels Of Anxiety, Anastasiya Rumyantseva Kharlamova

Dissertations, Theses, and Capstone Projects

The current study employed a Pavlovian conditioning paradigm to investigate the influence of pre-stimulus unconscious threat anticipation on subsequent fear responses in associative learning. Additionally, we explored the differences in pre-stimulus anticipation among individuals with varying levels of anxiety. Electrodermal response (EDA) was chosen as a primary measure due to its robustness in fear conditioning paradigms. Moreover, the State-Trait Anxiety Inventory (STAI) was utilized to assess anxiety levels in participants. Twenty-seven subjects were recruited to determine if pre-stimulus skin conductance responses (SCR) would exhibit stimulus-specific patterns influenced by implicit cues (L-shaped configurations) that indicated an upcoming face or a house …

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 …

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 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 …

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 …

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 …

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 …

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 …

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 …
