Evaluating Recognition Memory Models From An Individual Differences Perspective, Kyle Gramer Featherston

Arts & Sciences Electronic Theses and Dissertations

Although recognition memory models have been thoroughly compared in various recognition memory paradigms, the relative reliability and validity of their parameters have not been thoroughly assessed using an individual differences approach. In two studies, I evaluated three models: the dual-process signal detection (DPSD) model, the continuous dual process (CDP) model, and the unequal variance signal detection (UVSD) model. In Study 1, participants performed a remember-know procedure that also included confidence ratings. When model parameters were estimated twice in the same individual, both key parameters from the DPSD model were reliable within an individual, whereas the CDP version of familiarity was …

Examining Individual Differences In Forgetting From Long-Term Memory, Christopher Lee Zerr

Arts & Sciences Electronic Theses and Dissertations

Forgetting reflects the decreased likelihood of memory retrieval over time. With a few exceptions, although the mean likelihood of retrieval (or retention) across experimental conditions may differ markedly, rates of forgetting across those conditions do not differ. Similarly, although groups (e.g., young and old adults) may differ in the amount retained at a given point in time, the rates of forgetting tend not to differ across groups. In contrast, recent work suggests that individual differences in rates of forgetting may emerge when more sensitive statistical analyses are used on person-level performance. Some person-level variables purported to influence forgetting rate include …

Material Difficulty And Individual Difference Factors Moderate The Eyewitness Confidence-Accuracy Relationship, Wenbo Lin

Arts & Sciences Electronic Theses and Dissertations

Recent studies have shown that eyewitness confidence is positively associated with high identification (ID) accuracy, but some eyewitness researchers have expressed concerns regarding the reliability of this confidence-accuracy relationship in applied settings (e.g., are there circumstances or moderator variables that make this relationship less reliable?). For the present study, we considered two types of moderator variables: material difficulty (i.e., the difficulty level associated with different sets of eyewitness stimuli) and individual difference factors such as face recognition ability. Experiment 1 examined whether these moderator variables significantly impair the confidence-accuracy relationship and Experiment 2 examined whether these same moderator variables equally …

The Role Of Fear Of Evaluation In Individuals' Perceptions Of Groups, Jin Shin

Arts & Sciences Electronic Theses and Dissertations

Social anxiety disorder (SAD) is associated with interpersonal impairment. One possible reason for this dysfunction is that people with SAD evaluate others differently on dimensions of warmth and dominance compared to individuals without the disorder. In the current study, we examined whether two core constructs of SAD, fear of negative evaluation and fear of positive evaluation, affect the judgments that people make about groups based on warmth and dominance. We also investigated whether racial similarity (i.e., whether someone is the same race as those they’re interacting with) and ethnic identity (i.e., one’s sense of belonging to a particular social group) …

An Integration Of Attachment And The Investment Model: Joint Predictors Of Accommodation In Romantic And Friendship Dyads, Samuel Y. Chung

Arts & Sciences Electronic Theses and Dissertations

The present two-wave research examines two frameworks for predicting relationship maintenance: adult attachment theory and the investment model of commitment. Expanding upon past work, I test models that integrate the two theories such that relationship satisfaction, alternatives, and investment size mediate the relationship between avoidance and commitment, and attachment anxiety moderates the investment model factors’ relationships with accommodation in romantic relationships and friendships. In romantic relationships, increasing partner anxiety reduced the relationship between actor relationship satisfaction and commitment whereas in friendships, increasing actor anxiety increased the relationship between actor relationship satisfaction and commitment. Further, increasing actor anxiety increased the relationship …

Does The Combination Of Spacing And Testing Promote Transfer Beyond Either Strategy Alone?, Zeynep Oyku Uner

Arts & Sciences Electronic Theses and Dissertations

Testing and spacing improve long-term retention and their combination boosts retention further. Despite the combined benefits of spaced testing, it is unclear whether these benefits extend to situations where students learn from lengthy and complex textbooks and need to use concept knowledge in novel ways. To address this issue, in the current study, college students were asked to read from a textbook and review key concepts twice, either back-to-back within the same session or in two sessions spaced two days apart. To review concepts, students either took definition quizzes with feedback (short-answer in Experiment 1, multiple-choice in Experiment 2) or …

Impulsivity And Brain Organization In Childhood Suicide: An Adolescent Brain And Cognitive Development (Abcd) Study, Katherine Lopez

Arts & Sciences Electronic Theses and Dissertations

Rates of suicide have steadily increased across all age cohorts, revealing a particularly concerning rise in suicide among much younger age groups (10-15 years old). Recent efforts aimed at understanding suicide in youth have leveraged work from the adult literature to more pointedly examine candidate risk factors associated with childhood suicide. A noteworthy body of work has begun to clarify the role that impulsivity plays in elevating suicide risk among adults and adolescents, a critical link warranting further research in childhood suicide given the vast and well-documented changes occurring in self-control and brain maturity throughout development. Here, we examined a …

Testing Candidate Cerebellar Presymptomatic Biomarkers For Autism Spectrum Disorder, Zoe Wilson Hawks

Arts & Sciences Electronic Theses and Dissertations

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder diagnosed on the basis of social impairment, restricted interests, and repetitive behaviors. Contemporary theories posit that cerebellar-mediated error signaling impairments contribute to the causation of ASD. However, the relationship between infant cerebellar functional connectivity (fcMRI) and later ASD behaviors and outcomes has not been investigated. Such work is critical to establish early (presymptomatic) cerebellar correlates of ASD. Methods: Data from the Infant Brain Imaging Study (n=94, 68 male) were used to evaluate cerebellar fcMRI as a presymptomatic biomarker for ASD. Specifically, brain-behavior associations were analyzed for 6-month cerebellar connections in relation …

Clear Adjustment: Status Self-Concept Clarity And Emotion Regulation, Isidro Landa

Arts & Sciences Electronic Theses and Dissertations

One factor associated with a person’s adjustment during important life transitions is self-concept clarity (SCC)—“the extent to which the contents of an individual's self-concept (e.g., perceived personal attributes) are clearly and confidently defined…”. However, it is not fully understood why and for whom SCC predicts adjustment. Recent work suggests that SCC may function as a resource for regulatory functions, allowing one to focus on long-term self-relevant goals rather than narrowly focusing on regulating immediate discomfort associated with uncertainty. It is possible that having high SCC facilitates emotion regulation in such a way that it allows one to engage and further …

The Use Of Introspective Reports To Predict Subsequent Memory: Implementing Machine Learning For Judgment-Of-Learning Paradigms, Nathan Lloyd Anderson

Arts & Sciences Electronic Theses and Dissertations

Recent advances in machine learning have allowed for the use of natural language responses to predict outcomes of interest to memory researchers such as the confidence with which recognition decisions are made. The present experiments were designed to leverage this novel methodological approach by soliciting free-response justifications of judgments of learning (JOLs) whereby people not only assess the probability with which they will later recognize individual items but also (for some items) justify the reasoning behind their judgment. Across all experiments and conditions, regression models trained on justification language showed above-chance prediction of subsequent memory success and outperformed models trained …

Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt

Arts & Sciences Electronic Theses and Dissertations

Research on the relationship between normal-range personality and cognitive aging has demonstrated consistent, but modest, effects. The current investigation seeks to increase our understanding of unhealthy cognitive aging by examining the maladaptive extremes of personality. Borderline and avoidant personality disorder (PD), but not obsessive-compulsive PD, were hypothesized to show prospective associations with cognitive aging. Interpersonal stress was expected to mediate these relationships. The current investigation tested these hypotheses in two longitudinal studies of older adulthood: the Alzheimer’s Disease Research Center cohort (ADRC, N = 434, Mage = 69.95, 56% women) and the St. Louis Personality and Aging Network study (SPAN, …

Altered Network Organization And Screen Time Use In Childhood Attention-Deficit / Hyperactivity Disorder (Adhd), Elizabeth Jane Hawkey

Arts & Sciences Electronic Theses and Dissertations

Introduction: Symptoms of attention-deficit/hyperactivity disorder (ADHD) have been associated with alterations in functional connectivity involving networks in the developing brain that support optimal cognitive control. However, a clear profile of altered connectivity has yet to emerge, and it remains unclear whether changes in behavioral patterns such as screen time (ST) contribute to ADHD symptomatology and altered connectivity in networks that support cognitive control. The current study examined connectivity between large-scale networks associated with cognitive control (CC), measures of executive function (EF) which index CC, and ST in children with ADHD. Methods: Our sample included 11,874 children (ages 9-11, 52% male) …

Targeted Memory Reactivation During Mind-Wandering In Younger And Older Adults, Jessica Nicosia

Arts & Sciences Electronic Theses and Dissertations

Mind-wandering (MW) is a universal cognitive process that is prevalent across individuals and in our everyday lives. It is estimated that over 95% of Americans experience MW every day and that ~30% of our everyday thoughts consist of MW. Despite its pervasiveness in our everyday lives, the nature of how MW interacts with other cognitive processes remains a scientific blind spot. Two interrelated issues regarding the nature of MW in the context of healthy aging were ad-dressed across five experiments. First, given the frequency of MW in our everyday lives, it is important to understand if it serves a functional …

Which Task To Choose? The Impact Of Associative Retrieval Of Event Files On Voluntary Task-Switching Performance In Younger And Older Adults, Emily Carole Streeper

Arts & Sciences Electronic Theses and Dissertations

Previous task-switching research has demonstrated how prior experience can impact subsequent task-switching performance (i.e., reaction times, task choice) through associative retrieval, the creation and retrieval of event files. Event files, episodic traces which contain information about the stimulus, prior context, and action performed, can be implicitly retrieved when re-encountering information from the prior experience (e.g., stimulus repetition). The effect of associative retrieval on task-switching performance has been examined in younger adults, but few studies have investigated this effect in older adults. This gap is especially glaring in the voluntary task-switching literature where only one study to date has explored how …

Examining Anti-Lgbt Consequences Of Perceiving Anti-Christian Bias, Chad Miller

Arts & Sciences Electronic Theses and Dissertations

Christians in the US report increasing perceptions of anti-Christian bias, but little research has examined the consequences of these perceptions. Three Experiments provide evidence that for White, heterosexual, cisgender Christians, perceiving anti-Christian bias causes prejudice against gay and lesbian people – particularly when the latter are perceived as influential. Participants primed with anti-Christian bias reported lower warmth toward gay and lesbian and transgender people (relative to those who read about bias toward an outgroup) (E1 and E2). This effect was stronger for Christians who see gay people and transgender people, respectively, as having a significant cultural influence in U.S. society …

Person-Centered Profile Consistency: A Test Of Longitudinal Personality Consistency, Amanda Wright

Arts & Sciences Electronic Theses and Dissertations

Test-retest correlations are a common way to quantify stability in personality. However, these single estimates obscure patterns of consistency as well as individual differences in consistency. Importantly, examining patterns of consistency provides insights into the underlying processes driving personality development. The current study used Bayesian multilevel asymptotic models to examine trends of person-centered consistency using item-level profile correlations across four to nine waves with four datasets (N = 21,616). Results indicated that there were, on average, very high levels of profile consistency across time, highlighting one aspect of the stable nature of personality. There were notable individual differences in …

A Secondary Data Analysis Of The Prevalence Of Reported Dementia And Subjective Cognitive Decline Across U.S. National Surveys, Matthew C. Picchiello

Arts & Sciences Electronic Theses and Dissertations

Within the United States, many large-scale, nationally representative studies exist with the goal of tracking and monitoring aspects of health. These studies are often used to establish the prevalence of dementia and subjective cognitive decline (SCD) in the population. The goal of the current study is to examine how different population-based studies probe respondents about conditions related to cognitive impairment, and to assess similarities and differences in point estimates. We reviewed eight studies and identified comparable items related to dementia and SCD. We calculated design-appropriate point prevalence estimates and compared weighted estimates across studies, finding a wide range and statistically …

The Effects Of Question Difficulty Order On Metacognitive Judgments During An Online Test, Wei-Chieh Fang

Arts & Sciences Electronic Theses and Dissertations

Three experiments were conducted to examine the effects of question difficulty order on people’s judgments of test performance and test experiences. Building on the finding that ordering questions from easy to hard often leads to overconfidence (i.e., a retrospective bias), the study aimed to examine the generality and robustness of this effect by having participants from a diverse population take an online test and then make a post-test judgement of their performance. In addition to using the same ascending and descending order of difficulty as prior research, the study also explored how the U-shaped order (e.g., easy-hard-easy) and report option …

Fearful Versus Dismissive Beliefs About Emotion: Divergent Pathways To Non-Acceptance Of Emotion, Natasha Haradhvala Bailen

Arts & Sciences Electronic Theses and Dissertations

High non-acceptance of emotion, or the rejection of one’s own emotional experience as bad or unacceptable, is consistently associated with depressive pathology, including elevated depressive symptoms and past and current major depressive (MDD) diagnoses. To progress toward a fuller understanding of non-acceptance and depressive pathology, it is important to identify other associated constructs that could theoretically contribute to this association. Indirect evidence suggests that negative beliefs about emotion—that is, stable underlying negative beliefs about the meaning, value, or consequences of one’s emotions—could be one such factor, as could negative emotion intensity and emotional clarity (or the degree to which one …

The Role Of Selection History In Low-Prevalence Visual Search, Kendra Chamlee Smith

Arts & Sciences Electronic Theses and Dissertations

The low prevalence effect (LPE), the tendency for observers to be more likely to miss rare targets than frequent targets, is a robust error and is difficult to reduce. The LPE is an obstacle in a variety of real-world search tasks in which targets are rare, including baggage screening and some medical imaging. The LPE is thought to occur because when an observer searches for a low-prevalence target, over time, the observer may become both more willing to indicate a target is not there and more likely to end the search early. The present experiments employ three selection history effects, …

Self-Regulated Study Time Allocation To Enhance Learning And Item Difficulty Compensation, Eylul Tekin

Arts & Sciences Electronic Theses and Dissertations

Few studies have examined whether self-regulation of study time allocation is beneficial for learning. In four experiments, the present dissertation investigated the effectiveness of self-paced study relative to fixed-rate study in which subjects did not regulate their study time. More specifically, the present dissertation examined 1) whether self-paced study enhanced retention and item difficulty compensation (i.e., reduced retention differences between easy and difficult items) relative to fixed-rate study under different levels of monitoring accuracy, and 2) whether improving monitoring accuracy facilitated the effectiveness of self-paced study. In all experiments, subjects studied easy and difficult word pairs either under self-paced study …

Psychological Construct Validity, Caroline Marie Stone

Arts & Sciences Electronic Theses and Dissertations

A primary concern for any psychological research project is determining how to measure unobservable mental entities, such as "implicit memory", or "intelligence". Psychologists say that a measure has construct validity when they believe that a measurement method measures the construct they intend it to measure, where a construct is any theoretical term that refers to a mental entity. Construct validity, then, is the process of justifying one's belief that a measure has construct validity. My dissertation seeks to answer three related questions, 1. What is construct validity?, 2. What is the best epistemic theory of justification for construct validation?, and …

The Feeling Mind, Maria Doulatova

Arts & Sciences Electronic Theses and Dissertations

According to standard conceptions of agency, our reasons and intentions guide our actions. That is, goal-directed intentions play a key role in practical deliberation, planning, and execution of action. Furthermore, purposeful, goal-directed behavior warrants attributions of responsibility or “reactive attitudes” like resentment, anger, gratitude and forgiveness. However, recent developments of the dual-process theory of mind cast doubt on the empirical adequacy of this picture. While people take themselves to be responding to relevant reasons, they are often bypassed by irrelevant affective or automatic reactions. In this work I go beyond the dual-process theory of mind to offer a mechanistic account …

Modeling Semantic Structure And Spreading Activation In Retrieval Tasks, Abhilasha Ashok Kumar

Arts & Sciences Electronic Theses and Dissertations

Considerable work in the past decade has focused on representational accounts of how semantic information is acquired and organized, leading to the advent of modern Distributional Semantic Models (DSMs) that learn word meanings by extracting statistical information from large text corpora. However, mechanistic accounts for how meaning-related information is accessed and retrieved from semantic representations to ultimately produce responses within semantic tasks remain relatively understudied, especially for production-based tasks that require the selection of a single response amongst several activated competitors, such as in free association and sentence completion tasks. This dissertation evaluated the extent to which state-of-the-art DSMs combined …

Examining Mental Health In Northern Haiti, Michael Galvin

Arts & Sciences Electronic Theses and Dissertations

Mental health is a severely neglected field in low- and middle-income countries globally. Populations in countries such as Haiti demonstrate a high level of need for mental health services despite a lack of services and trained professionals. In addition to the dearth of biomedical services, local belief systems and explanatory models lead a majority of the population to rely on traditional medicine as their first option for care. The goal of this dissertation is to characterize mental health beliefs, practices, and services in northern Haiti by examining the relationship between traditional beliefs and mental illness, assessing the impact of traumatic …

Parental Psychological Distress After Prenatal Diagnosis Of Congenital Heart Disease: Patterns, Predictors, And Impact On Early Outcomes., Kathryn Mangin-Heimos

Arts & Sciences Electronic Theses and Dissertations

Congenital heart disease (CHD) is the most common birth defect and is often diagnosed during pregnancy. The transition to parenthood after prenatal diagnosis can be particularly challenging. Both mothers and fathers are at elevated risk for psychological distress, yet early distress frequencies and patterns have not been well characterized. The impact of psychological distress on parents’ perceptions of their readiness to care for their infant after hospital discharge is currently unknown. The association of psychological distress with early infant neurodevelopment has also been under investigated. To examine these gaps in knowledge, we conducted a single center, prospective cohort study of …

Art And Empathy: Self Discovery In A Dark Forest, Younser Lee

Graduate School of Art Theses

According to the National Institute of Mental Health, 40 million people report feelings of depression, anxiety, and stress as the world moves at an increasingly rapid pace and faces unprecedented challenges. However, many ignore these negative thoughts and fail to acknowledge them as a serious issue. My art, which shares my own experiences, creates safe, cathartic places for viewers to think about their own emotional experiences. Crucial to this process is my use of daily objects and the creation of individualized, participatory, and multisensory experiences.

My art relates to daily life and the negative emotions that we experience daily. I …

Changes In Usage And Perceptions Of Effectiveness Of Learning Strategies Of High School Students During A Rigorous Academic Experience, Emily Een

Arts & Sciences Electronic Theses and Dissertations

Students’ use of effective learning strategies facilitates durable learning and academic success. The present research investigates changes in the learning strategies of 2,082 high school students in a dual-enrollment program. All students in the current study were participating in the program for the first time, and data were collected over one academic year via pre- and post-course surveys. It is hypothesized that friction between students’ pre-course learning strategies and the strategy usage expected in the learning environment could promote a change in students’ use and perceptions of effectiveness of learning strategies. Using latent change score models, we investigated changes in …

Picky Eating In Children: Associations With Iq And Executive Functioning, Ara Nazmiyal

Senior Honors Papers / Undergraduate Theses

Picky eating is an under-researched behavior in children. The current study aims to assess what behaviors correlate with picky eating to better understand potential risk factors for Anorexia Nervosa. 111 children were evaluated at 5 and 6 years old, and a subset was evaluated again at 7 and 8 years old (n=36). Executive function and IQ were evaluated using parent reports and behavioral measures at baseline. Picky eating was reported by a parent questionnaire. Results showed deficits in shifting to be a predictor of higher picky eating behaviors at ages 5-6 years. Additionally, children who were reported extremely picky eaters …
