Testing P300-Based Biometric Authentication Paradigms, Jordan Razzak

Electronic Theses and Dissertations

Bench research suggests that P300 amplitude is greater in response to self-relevant stimuli compared to familiar stimuli. This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang

Electronic Theses and Dissertations

Information is encoded and stored in three types of memory: sensory memory (SM), short-term memory (STM), and long-term memory (LTM). SM has a large capacity but retains information for only a brief period. When information transfers to STM, only a limited amount can be stored. Information in STM can then be transferred to LTM, which has a much larger capacity and longer retention time. STM is often conceptualized as working memory (WM) to highlight its role in active information processing. Due to the limited capacity of STM, it is commonly believed that STM serves as the bottleneck for information processing. …

Emotion Regulation, Reasoning, And Procedural Safeguards In Politically-Polarized Moral Dilemmas., Alanea Graci

Electronic Theses and Dissertations

Societal disputes often stem from polarized moral dilemmas. Procedural justice and self-determination (PJSD) afforded by societal decision-making processes may influence cooperation and acceptance in these dilemmas. However, moral conviction can sometimes overshadow PJSD, causing morally-opposed individuals to avoid deliberation, become uncooperative, or reject decision outcomes. I conducted two experiments to explore the role emotions (emotion regulation) and procedural safeguards for democratic deliberation (e.g., equal discussion time, rules for civility) play in these situations. I examined the topic of abortion in the U.S. after the Supreme Court’s June 2022 reversal of Roe v. Wade. Undergraduates at a large, urban Midwestern university …

Differences In Performance In Mental Rotation And Short-Term Free Recall In Gender Minorities, Katheryne Renee Wood

Electronic Theses and Dissertations

The study examined mental rotation, short-term free recall, state anxiety, and gender expression through masculinity and femininity. This study addressed gaps in literature examining gender differences in gender minority groups by investigating gender differences in two tasks: mental rotation and short-term recall. Participants are categorized into four gender groups: cisgender men, cisgender women, non-binary, and binary transgender. In accordance with previous literature, it was hypothesized that men would outperform women in mental rotation, women would outperform men in short-term free recall performance, and that non-binary individuals would operate separately from other groups. Anxiety was recorded as a possible covariate, but …

Exploratory Learning In Two Modalities: Tabular Vs Graphical., Lianda Velic

Electronic Theses and Dissertations

In traditional educational settings, an instructor delivers a lecture prior to providing students a practice activity. Exploratory learning reverses this order to encourage active learning and engagement, typically improving learning outcomes. However, more research is needed in order to determine how to optimally design exploratory learning materials, and how differences in such design impact learning processes and outcomes. The current study investigated the impact of instructional order and activity modality type (tabular or graphical) on learning outcomes. Undergraduate students (N=252) were taught the statistical concept of consistency and the formula to compute standard deviation. In the instruct-first condition, …

Perceiving, Processing, And Evaluating Infant Facial Affect In Potential Parents: An Erp Study, Tiffany Bonnagio

Electronic Theses and Dissertations

Evidence for differences between assigned female at birth (AFAB) and assigned male at birth (AMAB) perceiving, processing, and evaluating infant faces has been mixed. The current study examined whether expected parental self-efficacy (EPSE) and desire for children predicts event-related potentials (ERPs) to infant facial affect in potential parents. No scale for EPSE exists. Therefore, we reworded the Perceived Maternal Parental Self-Efficacy scale from present to future tense. There was no correlation with EPSE scores, ERPs, or behavioral data. No difference was found between AFAB and AMAB in accurately evaluating infant faces; however, AFABs responded more quickly. ERP data revealed significantly …

Developing A Comprehensive Cognitive Model Of Math Achievement, Nina Anderson

Electronic Theses and Dissertations

Recently, downward trends have been reported in U.S. children’s math performance following school disruptions during COVID-19 amidst longstanding concerns for instruction and curricula within the subject. In support of efforts to remedy these declines, the current work presents two studies dedicated to identifying cognitive factors that are most strongly related to math performance, and which therefore offer promising potential targets for assessment and intervention. Both studies use data from the Colorado Learning Disabilities Research Center, which includes participants ages 8 - 16 and multiple well-validated measures of all constructs of interest. Study 1 tests three alternative latent cognitive models of …

Emotional Content In Working Memory Processes: An Fmri Study., Manal Zafar

Electronic Theses and Dissertations

Working memory (WM) is a dynamic system that processes and manipulates both goal-relevant and goal-irrelevant information, integral to higher-level cognition and executive control (Fujii, 2001; Nyberg & Erikkson, 2016). The processing and manipulation of representations is modulated by the affective nature of the information (Pessoa, 2009) such that negative information can either impair or enhance WM processing. WM impairments are seen commonly across clinical disorders such as depression, anxiety, PTSD and schizophrenia (Levens & Gotlib, 2010; Joorman et a., 2011; Brodziak et al., 2015). Specifically, negative information is known to have differential processing in WM compared to neutral and positive …

Informed Consent Document Delivery: Effects On Appalachian Caregivers' Comprehension, Trust In Researchers, And Willingness To Participate, Tess A. Simpson

Electronic Theses and Dissertations

The purpose of the present study was to investigate whether altering an informed consent document (ICD), in ways that either promote or inhibit accessibility, would affect potential participants’ willingness to participate in a child development laboratory-based study. Specifically, I was interested in assessing the willingness to participate of historically underrepresented groups, especially Appalachian caregiver-child dyads. I altered three parameters of a previously approved and employed ICD to explore whether these parameters impacted Appalachian caregivers’ comprehension of the study, willingness to participate, and trust in the researchers. The manipulated parameters included reading level, utilization of illustrative pictures, and inclusion of text-to-speech …

Children's Beliefs About Search Engines., Lauren N. Girouard-Hallam

Electronic Theses and Dissertations

Children rely on information from other sources to think and learn about the world around them. As the world around them digitizes, their options for where to seek new information have expanded to include technological sources like Google Search. This dissertation examines what factors impact children’s trust in search engines, particularly Google. In the first set of studies, 4- to 8-year old children were asked whether technological informants and a teacher could answer stable and changing questions, and which informant would have the better answer. With age, children endorsed the Google search engine at higher rates and the teacher at …

Applying Exploratory Learning Methods To Sociopolitical Beliefs And Cognition., Sarah French

Electronic Theses and Dissertations

Americans are polarized along party lines across a variety of sociopolitical issues, including climate change and sustainability issues. Sociopolitical messaging often triggers biased processing that results in defensive rejection or biased elaboration (i.e., counterarguing) of belief-incongruent information. The current research examined whether exploratory learning activities, primarily applied in STEM-education research, can foster belief updating about polarized sustainability issues. Exploratory learning encourages people to engage with learning materials and arrive at their own conclusions before receiving direct instruction/messaging. In two experiments, participants reported their beliefs about carbon taxes and electric vehicle incentives (among other issues) before and after receiving counter-attitudinal persuasive …

P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak

Electronic Theses and Dissertations

Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically …

Comparative Analysis Of Acceptance And Commitment Therapy’S Effectiveness In An Intensive Outpatient Program Setting, Efrain Frank Ellin Iii

Electronic Theses and Dissertations

This thesis presents a comparative analysis of acceptance and commitment therapy (ACT) and treatment as usual (TAU) within an intensive outpatient program setting, evaluating their effectiveness in enhancing various dimensions of psychological well-being. Guided by two main research questions, the study investigates whether ACT demonstrates greater or equal effectiveness compared to TAU and if it provides more immediate effects on psychological well-being within three weeks. Utilizing a quasi-experimental design, the research incorporates a comprehensive array of measurement tools to assess outcomes related to anxiety, depression, stress, psychological flexibility, cognitive flexibility, emotion regulation, mindfulness self-efficacy, and life satisfaction among participants. The …

A Phenomenological Study Of School Psychologists: The Influence Of Implicit Bias On The Disproportionate Identification Rates Of African American Students Evaluated For Emotional Disturbance, Sonya Coe-Milo

Electronic Theses and Dissertations

As advocates, school psychologists remain ethically responsible and uniquely positioned to identify social injustices and promote nondiscriminatory practices in prekindergarten through grade 12 public education institutions. Implicit bias and its influence on African American students is one such practice. In public education, implicit bias contributes to discipline disproportionality, differentiated teacher support, pedagogical practices, and adult perceptions and expectations of appropriate and inappropriate behaviors. These factors directly correlate to the disproportionate identification rates of African American students for special education and related services. Therefore, this phenomenological qualitative study examined the personal, lived experiences and perceptions of school psychologists regarding implicit bias …

Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel

Electronic Theses and Dissertations

A Faustian Bargain refers to an individual making a “deal with the devil,” exchanging something moral or sacred for an unattainable earthly good. The Faustian Bargain has been used to describe a ubiquitous social dilemma inherent to human civilization: exchanging individual liberty for public goods (e.g., security) provided by societal leaders and governments (Ostrom, 1980). Research on Faustian Bargains often examines tradeoffs between outcome utility (i.e., value derived from the outcomes of a decision) and procedural utility (i.e., value derived from being involved in the decision process (e.g., Frey et al., 2004). Much of the research on Faustian Bargains has …

Risky Behavior As Motivated Emotion Regulation: A Mixed-Method Approach, Lyneé A. Herrera

Electronic Theses and Dissertations

Engaging in risky health behaviors is a ubiquitous human experience that often marks developmental progression from adolescence into adulthood. While much previous research has framed risky behaviors in terms of negative legal, social, and public health consequences, less empirical work has been done on potential benefits of their engagement. A growing body of research has identified emotion regulation deficits as a significant driver of risky behavior engagement, suggesting that these behaviors may offer perceived emotional benefits when other regulation strategies are less accessible. Previous research has shown that emotional outcomes can be influenced by the regulation strategies one chooses to …

Interactive Computer-Based Simulations As Exploratory Learning Activities., Derek Mcclellan

Electronic Theses and Dissertations

Typical college lectures follow a direct instruction framework, where instructors deliver a lecture, followed by an activity. Exploratory learning flips this routine by providing students with an activity prior to instruction. Research suggests that this inversion benefits students’ conceptual understanding and ability to transfer their knowledge. The majority of exploratory learning tasks in the literature are problem-solving activities. The current work investigates the use of computer-based simulations during exploratory learning, and whether manipulating the cognitive load of the activity impacts learning. In Experiment 1, undergraduate students (N=66) were randomly assigned to explore a simulation-based circuit construction activity prior …

False Memories Are Impacted By Semantic Pairing Of Drm Lists., Ryan Coleman

Electronic Theses and Dissertations

In the DRM paradigm, experience of semantically related words leads to false memories of related words called critical lures. These false memories serve as evidence that the relationship between items in a DRM list contribute to an overall gist or central concept for the experience. The present studies aim to investigate whether the higher-order semantic relationship that exists between different DRM lists can also influence recognition memory. Study 1 compared memory confidence ratings for list items and critical lures to two metrics: “Temporal Contiguity”, how closely in time lists appeared to each other at encoding, and “Semantic Distance”, the semantic …

Reference Frames In Human Sensory, Motor, And Cognitive Processing, Dongcheng He

Electronic Theses and Dissertations

Reference-frames, or coordinate systems, are used to express properties and relationships of objects in the environment. While the use of reference-frames is well understood in physical sciences, how the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain the transition from egocentric (based on the observer) to exocentric (based outside the observer) reference-frames to account for the perception of relative motion. In a second project, we focus …

Interactions In The Mind: Examining Metacognition's Role In Entrepreneurial Performance, John Sebesta

Electronic Theses and Dissertations

To better understand the mental processes that shape entrepreneurial performance, this dissertation examines the moderating effect of metacognitive abilities on the relationship between cognitive style and entrepreneurial alertness on performance at the opportunity identification and planning stages of the entrepreneurial journey. Prior research identifies these factors as components of an entrepreneurial mindset. However, the present research develops and examines theoretically driven predictions regarding how the factors interact. Using a sample of seventy teams participating in a business plan competition enables performance evaluation at these early steps in the entrepreneurship process. The hypotheses were not supported, but post hoc analyses indicate …

Process Depletion In Emotion Regulation, Christian Capistrano Boeckner

Electronic Theses and Dissertations

The ability to regulate emotions via reappraisal is considered an important skill that is associated with greater well-being. However, the effectiveness of emotion regulation is impacted by individual differences, and its adaptiveness may vary depending on context. For example individuals from vulnerable populations such as children and mothers in the context of poverty often demonstrate less optimal reappraisal, that is in turn associated with maladaptive behaviors. Given its consequence on mental health, it is critical to understand mechanisms that influence reappraisal to maximize its adaptive consequences. The current study explored conditions that could either facilitate or impair reappraisal success. We …

Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley

Electronic Theses and Dissertations

Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …

The Effect Of Typewriting Vs. Handwriting Lecture Notes On Learning: A Systematic Review And Meta-Analysis., Timothy Schaun Lau

Electronic Theses and Dissertations

This study is a systematic review and meta-analysis of studies examining the effect of note-taking modality during lecture, that is, taking notes by hand using pen and paper vs. taking notes using a keyboard and computer, on learning among secondary and postsecondary students. I begin with a review of the literature and theoretical introduction to the theories and terms used. From a theoretical standpoint, there are strong reasons to believe that taking notes by hand might offer recall benefits relative to taking notes using a computer and keyboard. At the same time, I point out that one problem, which I …

Adverse Childhood Experiences And Quality Of Life: A Mediating Role Of Physical Activity And Executive Function, Loni Parrish

Electronic Theses and Dissertations

ACEs have been associated with heightened risk for a range of chronic health problems, substance use, and cognition in adulthood (Center for Disease Control (CDC), 2019; Hinojosa et al., 2017). One potential protective factor is physical activity (McEwen, 2016; Wu et al., 2013). Physical activity is associated with sustaining overall health, improving mental health by reducing symptoms of depression and anxiety (Murri et al., 2019; Sharma et al., 2006; Tasci et al., 2019), and maintaining a healthy body weight and BMI (WHO, 2021). Therefore, this study examined whether barriers to physical activity, physical activity levels, and executive outcomes serve as …

Individual Characteristics Of Postsecondary Underachievement, Natasha Godkin

Electronic Theses and Dissertations

Underachievement in postsecondary education has been a growing concern for educators and researchers. Higher education institutions have implemented early alert systems to identify students performing below standards. This early warning system has major limitations that confine it to an identification only approach. The current study aimed to investigate the psychometric properties of the Student Attitude Assessment Survey-R (SAAS-R) in a postsecondary sample. First, a confirmatory factor analysis validated the SAAS-R in a postsecondary sample. Predictive validity was then investigated by identifying students as underachieving or achieving based on responses to the SAAS-R and via a regression-based discrepancy model (ability vs. …

The Effects Of Rejection Sensitivity On Attention And Performance Monitoring Event-Related Potentials, Elizabeth Ridley

Electronic Theses and Dissertations

Rejection sensitivity (RS) can have significant effects on interpersonal relationships. Previous research has shown the negative social effects of RS, but less is known about the cognitive implications of having high levels of RS. The current study examined the effect of RS on various event-related potential (ERP) components associated with performance monitoring (error-related negativity, ERN; feedback-related negativity, FRN) and attention (P300; late positive potential, LPP). Participants completed a social or nonsocial Flanker task and an emotional Stroop task. Results showed an increased ERN on error trials for individuals with higher RS. Although the FRN, P300, and LPP were not influenced …

Effects Of Dissociation And Hyperarousal On Item And Association Memory, Naomi M. Wright

Electronic Theses and Dissertations

Dual representation theory (DRT) asserts that when an individual experiences an acutely stressful or traumatic event, encoding of memory of individual parts of an event (i.e., items) is enhanced, while connections between parts of an event (i.e., associations) is impaired due to peritraumatic changes in cognitive functioning. The current project sought to refine understanding of DRT by examining the differential effect of dissociation and hyperarousal, two common peritraumatic cognitive reactions, on memory for item and association information. Method: Using experimental methods from the cognitive study of memory, two studies evaluated how individual differences in cognitive states (Study 1) and experimentally …

The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen

Electronic Theses and Dissertations

The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …

Positive Body Image And Cognitive Processing Style, Brittney Dumas

Electronic Theses and Dissertations

Social media use among young people is ubiquitous and has been associated with body image concerns. Though prior work has overwhelmingly focused on “screen time,” increasing evidence highlights the role of subjective social media experiences in driving this association, rather than mere frequency of use. In the current study, body appreciation was tested as a trait-level variable that may protect women from the negative impact of appearance-focused fitspiration images, which have become common in social media platforms. Appearance schema activation and appearance-related self-discrepancy were examined as two social-cognitive processes in which self-protective tendencies may emerge. Fitspiration exposure predicted appearance schema …

It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey

Electronic Theses and Dissertations

The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …
