Process Dissociation Analyses Of Memory Changes In Healthy Aging, Preclinical, And Very Mild Alzheimer Disease: Evidence For Isolated Recollection Deficits, Peter R. Millar

Arts & Sciences Electronic Theses and Dissertations

Recollection and familiarity are independent processes that contribute to memory performance. Recollection is dependent on attentional control, which breaks down in early-stage Alzheimer disease (AD), whereas familiarity is independent of attention. The present study examines the sensitivity of recollection estimates based on Jacoby’s (1991) process dissociation procedure to AD-related biomarkers in a large sample of well-characterized cognitively normal older adults (N = 519) and the extent to which recollection discriminates these individuals from individuals with very mild symptomatic AD (N = 64). Participants studied word pairs, e.g., “knee bone,” then completed a primed, explicit, cued fragment-completion memory task, e.g., “knee …

How Do The Largest And Smallest Baboon Species Compete For Reproductive Success In A Natural Hybrid Zone?, Monica Mcdonald

Arts & Sciences Electronic Theses and Dissertations

This dissertation examines hybridization between two of the most divergent baboons, the kinda baboon (Papio kindae) and the grayfooted chacma baboon (P. ursinus griseipes), which differ markedly in body size and in some social behavior. Preliminary research revealed hybridization between males of the smaller species (kinda) and females of the larger species (grayfoots), but not the reverse. Using behavioral, phenotypic, and genetic data collected from a single hybrid group in Kafue National Park from May 2012 to July 2013, I evaluated whether a similar asymmetry was borne out in this group and whether phenotypic markers of species assignation matched genotypic …

The Violence Of Abstraction: Learning To Live With Type-2 Diabetes In Everyday Life, Jenny Epstein

Arts & Sciences Electronic Theses and Dissertations

The impetus for this project grew out of my experience working as a pharmacist in a federally-funded ambulatory-care clinic In Tacoma, WA. Many people seen at the clinic struggled with type-2 diabetes (T2DM) and over time, I began to see this condition not only as a biological disorder, but also as a complex symptom of both macro-level social history and micro-level daily activities. I also began to see how the emphasis on medical abstraction in the form of measuring, monitoring and scheduling into daily routines, while necessary to control T2DM, created a gap between lived experience and the broader social …

What Does Your Major Say About You? Selection, Socialization, And Person-Environment Fit In The Context Of Personality Development, Leah Schultz

Arts & Sciences Electronic Theses and Dissertations

A young adult’s years spent at a four-year undergraduate institution constitute a critical time in human development. With the vast array of social, academic, and extracurricular options available for an undergraduate to explore, it is unsurprising that during this time, individuals change in relatively drastic ways compared to other parts of the lifespan (Arnett, 2000; Donnellan, Conger, & Burzette, 2007). A dizzying array of factors may contribute to an individual’s development during the college years: being away from home for the first time, interacting with professors, TAs, friends, and romantic partners, and involvement in academic projects, internships, and university organizations …

The Effect Of Social Anxiety On Social Support Behavior In Close Friendships, Marilyn Piccirillo

Arts & Sciences Electronic Theses and Dissertations

Quality of interpersonal relationships is a strong predictor of mental and physical health outcomes (Cacioppo, & Hawkley, 2003) and individuals with social anxiety disorder (SAD) report increased relationship impairment (Schneier et al., 1994). Evidence from the interpersonal literature suggests that individuals with SAD exhibit interpersonal constraint, in that they rate themselves as colder and more restricted in the amount of warmth they display with close others (Rodebaugh, Bielak, Vidovic, & Moscovitch, 2016). This study aimed to determine behavioral differences in the provision and receipt of support behaviors as a function of generalized SAD (GSAD). Participants (n = 92) and their …

Approaching Individual Differences Questions In Cognitive Control: A Case Study Of The Ax-Cpt, Shelly Cooper

Arts & Sciences Electronic Theses and Dissertations

Investigating individual differences in cognition requires addressing questions not often thought about in standard experimental designs, especially those regarding the psychometrics of a task. The purpose of the present study is to use the AX-CPT cognitive control task as a representative case study example to address four concerns that may impact the ability to answer questions related to individual differences. First, the importance of a task's true score variance for evaluating potential failures to replicate predicted individual differences effects is demonstrated. Second, evidence is provided that Internet-based studies (e.g., MTurk) can exhibit comparable, or even higher true score variance than …

Meta-Emotions In Daily Life: Associations With Emotional Awareness And Depression, Natasha Haradhvala

Arts & Sciences Electronic Theses and Dissertations

Meta-emotions are emotions that occur in response to other emotions (e.g., guilt about anger). Although preliminary evidence indicates that depression is associated with a greater likelihood of meta-emotions, much remains unknown about meta-emotions, including how regularly they are experienced and whether emotional awareness constructs (including attention to and clarity of emotion) influence their occurrence. In the present study, we aim to establish norms for meta-emotions in everyday life, determine whether increased emotional awareness is associated with a greater likelihood of meta-emotions, and examine whether negative emotions about negative emotions (negative-negative meta-emotional experiences) are associated with depressive severity. We recruited an …

Examining Criterion A: Dsm-5 Level Of Personality Functioning As Assessed Through Life Story Interviews, Patrick Cruitt

Arts & Sciences Electronic Theses and Dissertations

Several studies have examined the Level of Personality Functioning Scale (LPFS) from the DSM-5 as rated using diagnostic interviews conducted by trained clinicians (Few et al., 2013; Zimmermann et al., 2014). These studies have demonstrated the reliability and validity of the LPFS, but suffer from a common limitation, namely, that diagnostic interviews probe specifically for information pertaining to functioning. This probing may inflate reliability and introduce confounds into the assessment of functioning. The purpose of the current analyses is to examine the reliability and validity of personality functioning ratings obtained in the absence of information pertaining to personality disorder criteria. …

Letter Teaching In Parent–Child Conversations, Molly Farry-Thorn

Arts & Sciences Electronic Theses and Dissertations

Societies engage in cross-generational transfers of information, enabling cultural transmission of skills such as tool use and language (Tomasello, 2001). Reading and spelling are two of the most important cultural tools that are transferred to children in modern societies. This transfer begins with informal experiences in the home and continues with formal teaching at school. One skill that is critical to a child’s success during the first years of reading and spelling instruction is decoding, which is the ability to sound out written words. Decoding ability depends, in part, on a child’s knowledge of letters (Lonigan, Burgess, & Anthony, 2000). …

Decision Making In Older Adults: A Comparison Of Delay And Probability Discounting Across, Ariana Vanderveldt

Arts & Sciences Electronic Theses and Dissertations

The value of an outcome is affected both by the delay until its receipt (delay discounting) and by the likelihood of its receipt (probability discounting). The discounting framework has greatly aided in modeling and understanding decision-making, particularly in the areas of impulsivity, but these findings have overwhelmingly been based on research with young adults. In three experiments, the current study extended the discounting framework by examining choice by older adults. Experiments 1 and 2 found that both young and older adults discounted delayed outcomes and probabilistic outcomes and that their choices were well-described by the same hyperboloid model. Both young …

Dynamic Adjustments Of Cognitive Control In Healthy Aging: A Diffusion Model Analysis, Andrew Jacob Aschenbrenner

Arts & Sciences Electronic Theses and Dissertations

The control of attention over salient yet irrelevant information is a critical component of goal-directed behavior. Compared to younger adults, older adults often produce larger interference effects in tasks which tap selective attention, a deficit that has typically been viewed as reflecting an age-related decline in attentional control processes. Interference in distinct, attentionally demanding tasks has produced different influences on the characteristics of underlying response time distributions leading to the assumption of different control mechanisms operating across various paradigms. More recently, accumulating research has shown that the magnitude of observed interference can be critically modulated by the congruency of the …

Perceiving Oldness In Parietal Cortex: Fmri Characterization Of A Parietal Memory Network, Adrian Gilmore

Arts & Sciences Electronic Theses and Dissertations

The manner in which the human brain recognizes certain stimuli as novel or familiar is a matter of ongoing investigation. The overarching goal of this dissertation is to improve our understanding of how this may be accomplished. More specifically, work contained herein focuses on a recently described "parietal memory network" (PMN; Gilmore et al., 2015) that shows opposite patterns of activity when perceiving novel or familiar stimuli: deactivating in response to novelty, and activating in response to familiarity. Critically, our understanding of this network is based on explicit memory tasks, in which subjects are deliberately instructed to learn or remember …

The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey

Arts & Sciences Electronic Theses and Dissertations

In a series of studies, I examined the degree to which fluid and crystallized abilities contribute to and interact during speech perception. During the aging process, crystallized abilities (e.g., linguistic and word knowledge) are largely preserved, while fluid abilities involved in the online manipulation of information (e.g., working memory and inhibitory control) decline with age. Importantly, these two components are critical for successful speech perception and comprehension. While prior research has proposed that older adults rely on crystallized knowledge to compensate for cognitive deficits in difficult listening conditions, this hypothesis has not been directly tested. Younger and older adults completed …

Utilizing Multiple-Level Category Information To Enhance Category Learning: Theoretical And Practical Considerations In Application To Authentic Natural Categories, Toshiya Miyatsu

Arts & Sciences Electronic Theses and Dissertations

Category learning is ubiquitous in science education. From botany courses teaching to identify different types of plants to geology courses teaching to distinguish various types of rocks, examples of category learning being a core of a course curriculum can be easily found. Using the educationally authentic rock categories, the current project examined whether category learning at a broad level (i.e., distinguishing between Igneous, Sedimentary, and Metamorphic rocks) could be enhanced by using category information at a more specific level (e.g., Harzburgite under Igneous, Breccia under Sedimentary, etc.). Both in Experiment 1 (broad- and specific- level information were presented simultaneously) and …

Anticipatory And Consummatory Pleasure And Displeasure In Major Depressive Disorder: An Experience Sampling Study, Haijing Wu

Arts & Sciences Electronic Theses and Dissertations

Pleasure and displeasure can be parsed into anticipatory and consummatory phases. However, existing research on pleasure and displeasure in major depressive disorder (MDD), a disorder characterized by anhedonia, has largely focused on deficits in the consummatory phase and most studies have been laboratory-based. Using experience sampling, we compared anticipatory and consummatory pleasure and displeasure for activities in the daily lives of adults with MDD (n = 41) and in healthy controls (n = 39). Participants carried electronic devices for one week and were randomly prompted eight times a day to answer questions about activities that they most and …

Market Effect: The Impact Of For-Profit Charter Schools On Racial And Socioeconomic Segregation, William Brett Robertson

Arts & Sciences Electronic Theses and Dissertations

For-profit charter schools are a controversial new development in public education. They combine a structural imperative to maximize profit for private shareholders with the social good of providing public education. This dissertation describes two analyses of for-profit charter schools designed to explore their impact on racial and socioeconomic segregation. The analyses utilize geographic information systems, multilevel modeling, and logistic regression to determine whether and how for-profit charter schools are likely to locate in demographically different neighborhoods, and/or educate demographically different student populations from other types of public schools. The results indicate that for-profit charter schools are less likely than other …

A Quantitative Genetic Analysis Of Craniofacial Variation In Baboons, Jessica Lynn Joganic

Arts & Sciences Electronic Theses and Dissertations

This dissertation is an explication of baboon craniofacial variation and its genetic basis. Intraspecific variation is the result of input from and complex interactions among genetic information, functional demands, and developmental processes. The relative effect of each of these on craniofacial variation, as well as the degree of inter-trait covariance, determines whether traits can respond to selection and what that response might look like. Using a sample of pedigreed baboons, I quantify craniofacial variation to address specific questions regarding the distribution and magnitude of phenotypic, genetic, and environmental variation patterns. In addition, I identify regions of the genome containing genetic …

Essays On Labor Economics, Sunha Myong

Arts & Sciences Electronic Theses and Dissertations

Chapter 1: Need-Based Aid from Selective Universities and the Achievement

Gap between the Rich and Poor

I study the role of need-based aid from selective universities in closing the achievement gap between the rich and poor high school students. I focus on the incentive aspect of need-based aid that can change high school student's effort choices. The impact of increasing need-based aid depends on the extent of borrowing constraints and how competition affects the relative performance of low- and high-income students. I develop a structural model of students' learning, application, and admission processes, and estimate it with the Education Longitudinal …

Essays On Liquidity, Banking, And Monetary Policy, Jaevin Park

Arts & Sciences Electronic Theses and Dissertations

The first chapter develops a new theory of bank capital requirements. A general equilibrium banking model is constructed in which deposit claims backed by bank assets support secured credit arrangements with limited commitment. Bank capital, a contingent claim on bank assets, is costly to hold when the value of assets is insufficient to support an efficient credit arrangement. However, if there is non-diversifiable aggregate risk, requiring banks to hold additional bank capital in the high-return state can be beneficial since it can relax the limited commitment constraint in the low-return state by affecting asset prices. Thus bank capital requirements can …

Make Love And War: Chinese Popular Romance In Greater East Asia, 1937-1945, Chun-Yu Lu

Arts & Sciences Electronic Theses and Dissertations

My dissertation examines Chinese popular romances produced and consumed in the Japanese colonized and occupied regions, including Taiwan, Manchukuo, and Shanghai, during the Second Sino-Japanese War. I investigate the complex relationships between emotion, representation, and consumption vis--vis wartime discourses and sociopolitical turmoil. Through extensive archival research in Taiwan, China and Japan, I (re)discovered and reevaluated five important wartime popular romance writers and their works. In addition to fiction, sequels, film and stage play adaptations, Japanese translation and readers/viewers responses all together create the cultural phenomena of the popular romance genre. In this dissertation I ask the following questions: How are …

Essays On Macroeconomics And Monetary Economics, Fatih Tuluk

Arts & Sciences Electronic Theses and Dissertations

My essays that are captured in two chapters of my dissertation focus on shadow banking system, collateralized debt arrangement and monetary policy. The first chapter studies the role of shadow banking in the recent financial crisis, the relationship between shadow banking and traditional banking, and it investigates the monetary policy reaction to overcome the financial frictions associated with the scarcity of collateral or shortages of safe assets that naturally led to the liquidity constraints. On the other hand, the second chapter studies the role of housing as a collateral or as a medium of exchange and it explores how the …

Essays On Theories Of Social Influence, Jiemai Wu

Arts & Sciences Electronic Theses and Dissertations

This dissertation studies strategic social influence from a theoretical perspective.

The first chapter extends Bikhchandani, Hirshleifer and Welchs informational cascade model by introducing two types of players: experts with high signal accuracy and laymen with low signal accuracy. If a small enough fraction of laymen are present in the population, the probability of having a correct cascade is strictly higher than if no laymen are present. This is because the presence of laymen makes experts less eager to follow suit, which increases the amount of private information revealed.

The second chapter asks the following question: when a decision makers (DM) …

Anxious Anticipation Of A Social Threat And Its Effect On Time Estimation, Natasha April Tonge

Arts & Sciences Electronic Theses and Dissertations

Time perception is a well-studied phenomenon; however, subjective experience of time and its relationship to affective states has received comparatively less attention in the literature (Grondin, 2010). Recently, it was suggested that anticipatory anxiety may also lead to an overestimation effect regarding angry faces in socially anxious individuals (Jusyte et al., 2014). In the present study, participants completed two temporal bisection tasks (TBT) in which they were asked to categorize a stimulus as being of short or long duration. Between the tasks, participants were to present a speech that served to provoke anxiety. In the present study, I aimed to …

Can We Walk? Environmental Supports For Active Travel In India, Deepti Adlakha

Arts & Sciences Electronic Theses and Dissertations

Background: Rapid rates of increase of obesity, diabetes, and associated chronic and co-morbid non-communicable diseases (e.g., cardiovascular diseases and some cancers) are being documented in India, yet in-country evidence-based research of associated risk factors is lacking. Physical activity has been identified as a preventative factor to counter the risk from obesity-related non-communicable diseases. Built environment supports for physical activity represent promising strategies to curb the rise in non-communicable diseases. Mounting research evidence suggests that the built environment can facilitate or constrain physical activity. However, a majority of this research has been conducted in developed nations. Built environment correlates of physical …

American Undergraduates Undone: Social And Intellectual Dysfunction On Campus, Noelle P. Jones

Arts & Sciences Electronic Theses and Dissertations

The pivotal, formative years of typical undergraduates, ages 18-22, represent a time when students mold their distinctive identities, social personalities, and intellects more intensively than during any other period of their lives. Developmental theorists Arthur W. Chickering and Linda Reisser call this process “journeying toward individuation—the discovery and refinement of one’s unique way of being—and also toward communion with other individuals and groups, including the larger national and global society” (35). In today’s college climate, students flummox and astound parents, professors, and researchers due to their individual immaturity and disengagement with learning. Although these complaints identify nothing new in America, …

Rostral Middle Frontal Gyrus Thickness Is Associated With Perceived Stress And Depressive Symptomatology, Lindsay J. Michalski

Arts & Sciences Electronic Theses and Dissertations

Elevated stress perception and depression commonly co-occur and have shared genetic and environmental influences, suggesting they may rest upon a common underlying neurobiology. The rostral middle frontal gyrus (RMFG), part of the dorsolateral prefrontal cortex, is critical for executive function, including emotion regulation and working memory. Variability in RMFG cortical thickness has been associated with both depression and stress-related phenotypes, although the directionality of these associations has been inconsistent thus far. The current study examined healthy participants (n=879) who completed the ongoing family-based Human Connectome Project were included in analyses. RMFG cortical thickness was computed from structural magnetic resonance imaging …

Exploring The Relationships Between Social Skills, Mental Health And Behavior In A Child Welfare Involved Population, Megan Anne Feely

Arts & Sciences Electronic Theses and Dissertations

Promoting child well-being is one of the three primary goals of the child welfare system. In contrast to safety and permanency, the other two primary goals, that are precisely defined in the federal statute, well-being remains undefined and poorly understood. Recently, the Administration on Children Youth and Families (ACYF) highlighted one facet of child well-being -- social and emotional well-being -- as a particular focus of the agency. These categories, i.e. behavior, emotional development and social functioning collectively are referred to as social and emotional well-being. The relationship between these constructs is unknown although it is likely that they are …

Essays On Macroeconomics, Duksang Cho

Arts & Sciences Electronic Theses and Dissertations

My dissertation is centered on economic heterogeneity endogenously derived from market imperfections or changes in technology. By introducing specific assumptions that capture a market imperfection or a change in technology, I study how the economic realities can affect resource distributions and aggregate outcomes in an equilibrium.

Chapter 1 studies the economic impacts of business groups by focusing on their pyramidal ownership structure given capital market imperfections. An entrepreneur can alleviate financial frictions by creating a pyramidal business group in which a parent firm offers its subsidiary firm internal equity finance. This endogenous creation of pyramidal business groups can beget asymmetric …

Essays On Economic Decision Making, Hee Chun Kim

Arts & Sciences Electronic Theses and Dissertations

My dissertation consists of three chapters and I take different approach in each chapter to investigate economic decision making behavior. The first chapter analyzes individuals strategic decisionmaking when players have replaceable identities and private information in a repeated prisoners dillmma game. The second chapter studies individuals non-strategic decision making when she has incomplete information about her underlying preference in a sequential choice situation. The third chapter experimentally examines a link between an individuals strategic thinking and nonstrategic decision making in a setting designed to elicit beliefs about independent random variables.

In the first chapter, I focus on strategic decision making …

Essays In Macroeconomics, Economic Development, And Growth, Lin Shao

Arts & Sciences Electronic Theses and Dissertations

Chapter 1: Trade credit in production chains In an economy where production takes place in multiple stages and is subject to financial frictions, how firms finance intermediate inputs matters for aggregate outcomes. This paper focuses on trade credit the lending and borrowing of input goods between firms in a production chain and quantifies its aggregate impact. Motivated by empirical evidence, our model shows how trade credit alleviates financial frictions through a process of credit redistribution and creation, thus leading to a higher output level in the steady state. However, the flow of trade credit is prone to disruptions when financial …
