Accuracy Matters For The Benefits Of Sleep After Retrieval Practice, Steven Dessenberger Dec 2019

Accuracy Matters For The Benefits Of Sleep After Retrieval Practice, Steven Dessenberger

Arts & Sciences Electronic Theses and Dissertations

Previous research suggests that while sleep and retrieval practice can each improve memory on their own, their benefits cannot be combined to produce an additive effect unless feedback is given during the initial test. These previous findings would seem to support a retrieval-as-consolidation of the testing effect, which states that the benefits of retrieval are the result of memory consolidation, a process that normally occurs during the sleep cycle. The present study sought to determine whether the retrieval-as-consolidation account held true when initial test accuracy was considered as a factor. Using foreign language word pairs, we examined the combined effects …


Children's Perceptions Of Status At The Intersection Of Race And Gender, Grace Reid Dec 2019

Children's Perceptions Of Status At The Intersection Of Race And Gender, Grace Reid

Arts & Sciences Electronic Theses and Dissertations

By 6 years of age, children associate males with higher status than females (Liben, Bigler & Krogh, 2001), and Whites with higher status than Blacks (Bigler, Averhart & Liben, 2003). However, little is known about how race and gender interact to influence children’s thinking about status. In Study 1, we asked whether children associate White men with higher status than other races and genders. Sixty children selected from among Black and White male and female targets the person who they thought would do familiar and novel jobs that varied in status. White men were the most likely to be chosen …


Fear Of Positive Evaluation And Negative Affect From Inclusion In Cyberball, Jason Ted Grossman Dec 2019

Fear Of Positive Evaluation And Negative Affect From Inclusion In Cyberball, Jason Ted Grossman

Arts & Sciences Electronic Theses and Dissertations

Fear of positive evaluation (FPE) is a construct related to social anxiety that involves discomfort when receiving positive attention and feedback from others. FPE research has increased over the past decade, and results suggest that it may be an important part of social anxiety for some individuals; however, it is not yet known whether FPE may also include discomfort from being included in social situations. Level of inclusion was hypothesized to moderate the relationship between FPE and negative affect from being over included such that those with high FPE would feel more uncomfortable the more they were included. To test …


Crip Time In Fin-De-Siècle Spain: Disability, Degeneration, And Eugenics, Erika Rodriguez Dec 2019

Crip Time In Fin-De-Siècle Spain: Disability, Degeneration, And Eugenics, Erika Rodriguez

Arts & Sciences Electronic Theses and Dissertations

A period of intense nation-building, the late nineteenth century was marked by the search for medical and legal solutions to the increasing number of bodies that did not align with culturally constructed expectations of productivity and reproduction in Spanish modernity. Authors of this time used representations of disability to engage in urgent political questions about population control and the rights of individuals in the face of increasing medical intervention. In carrying out this analysis, I raise the question of how representations of disability created a space to reconfigure the social values that determined what lives matter. Focusing on canonical realist …


Perceptual Precedence Or Increased Effort?: On The Mechanism Of The Small-Picture-Size Advantage In Category Learning, Toshiya Miyatsu Dec 2019

Perceptual Precedence Or Increased Effort?: On The Mechanism Of The Small-Picture-Size Advantage In Category Learning, Toshiya Miyatsu

Arts & Sciences Electronic Theses and Dissertations

I have previously identified a novel perceptual manipulation that enhances learning of some complex natural categories, and the current dissertation aims to uncover its mechanism. Specifically, learning of categories of tropical fish was enhanced when learned through small pictures (about 2º) compared to large pictures (about 19º). Through analyzing the previous results and extant theories in various domains, I identified two potential mechanisms through which this small-picture-size advantage manifested. The perceptual precedence hypothesis postulates that the processing of local dimensions is prioritized in large pictures and the processing of global dimensions is prioritized in small pictures. Therefore, small picture size …


Young Children’S Knowledge About The Role Of Print In Reading, Molly Farry-Thorn Dec 2019

Young Children’S Knowledge About The Role Of Print In Reading, Molly Farry-Thorn

Arts & Sciences Electronic Theses and Dissertations

Children begin to learn about the print in books and the role it plays in reading well before the onset of formal literacy instruction. Young children’s knowledge about precisely what readers are reading when they read books and who is able to read books has been studied primarily through interviews, but conclusions from this research are limited by methodological concerns. Three experiments examined whether pre-readers understand what part of a book is read and whether they distinguish between the skill of reading and the activity of reading. Although pre-readers were typically able to locate the print in a book, they …


Genomic Contributors To Individual Differences In Reward-Related Neural Activity, Lindsay Jane Michalski Dec 2019

Genomic Contributors To Individual Differences In Reward-Related Neural Activity, Lindsay Jane Michalski

Arts & Sciences Electronic Theses and Dissertations

Aberrant reward-related behavior, including impulsive and risk-taking behaviors, is a common feature of externalizing psychopathology (e.g., attention deficit hyperactivity disorder, antisocial personality disorder, and substance-use disorders). Through imaging studies, these behaviors have been linked to dysregulated reactivity within a diffuse reward-related corticostriatal neural network, including the striatum, frontal regions (namely orbital, ventromedial, and dorsolateral cortices), the insula, and the hippocampus. Because variability in risk-taking behavior and related psychopathology is moderately-to-largely heritable (i.e., with estimates ranging from 40 – 80%), a genetically-informed approach is well-positioned to provide valuable insight into the etiology of reward-related neural and behavioral phenotypes that characterize externalizing …


Investigating The Relationship Between Gaze Behavior And Audiovisual Benefit Across Various Speech-To-Noise Ratios, Lauren Gaunt Dec 2019

Investigating The Relationship Between Gaze Behavior And Audiovisual Benefit Across Various Speech-To-Noise Ratios, Lauren Gaunt

Arts & Sciences Electronic Theses and Dissertations

Speech perception improves when listeners are able to see as well as hear a talker, compared to listening alone. This phenomenon is commonly referred to as audiovisual (AV) benefit (Sommers et al., 2005). According to the Principle of Inverse Effectiveness (PoIE), the benefit of multimodal (e.g. audiovisual) input should increase as unimodal (e.g. auditory-only) stimulus clarity decreases. However, recent findings contradict the PoIE, indicating that it should be reassessed. One method for investigating the factors that contribute to AV speech benefit is to examine listeners’ gaze behavior with eye tracking. The present study compared young adults’ (N=50) gaze …


Neuroticism And Stressful Life Events: Probing Mechanisms Underlying Vulnerability To Stress-Related Depression, Erin Bondy Dec 2019

Neuroticism And Stressful Life Events: Probing Mechanisms Underlying Vulnerability To Stress-Related Depression, Erin Bondy

Arts & Sciences Electronic Theses and Dissertations

Elevated neuroticism (N) potentiates the depressogenic effects of stressful life events (SLEs). We first replicate this association using longitudinal data (N=971 older adults) from the St. Louis Personality and Aging Network (SPAN) study. Here, SLEs prospectively predicted future depressive symptoms, especially among those reporting elevated N, even after accounting for prior depressive symptoms and previous SLE exposure (NxSLE interaction: p=0.016, ΔR2=0.003). These findings were further replicated in cross-sectional analyses of the Duke Neurogenetics Study (DNS), a young adult college sample with neuroimaging data (n=1,343: NxSLE interaction: p=0.019, ΔR2=0.003). Because evidence suggests that stress may promote depression …


The Unique Effects Of Relatively Recent Conflict On Cognitive Control, Jackson Colvett Dec 2019

The Unique Effects Of Relatively Recent Conflict On Cognitive Control, Jackson Colvett

Arts & Sciences Electronic Theses and Dissertations

In tasks such as Stroop, our past experiences with conflict influence our ability to attend to goal-relevant information and ignore irrelevant information. There exists evidence that conflict experiences on at least two timescales affect cognitive control. The “immediate” timescale is evidenced by congruency sequence effects while the “long” timescale is evidenced by list-wide proportion congruence effects. What remains underspecified is whether relatively recent experiences with conflict may also uniquely influence cognitive control and how experiences on different timescales are weighted. The present, pre-registered experiments aimed to assess the role of relatively recent conflict by examining the potential effects of an …


Retrieval Of Past Events During Change Experience Is Associated With Memory For Change, Mary Hermann Dec 2019

Retrieval Of Past Events During Change Experience Is Associated With Memory For Change, Mary Hermann

Arts & Sciences Electronic Theses and Dissertations

A novel theory has emerged that examines how people process and comprehend change. Two experiments examined these theoretical mechanisms used to detect and recollect changes in everyday activities. Participants viewed movies of an actor performing narrative activities across two fictitious days. During the second movie, participants also completed a prediction task in which they were asked to predict what they thought was going to happen next. In Experiment 1, some activities repeated identically across the two days, some were repeated but changed on a critical feature (e.g. waking up to an alarm from a clock or a phone), and …


Double Trouble: How Children And Adults Decide When To Use Double Consonants, Ruth Caputo Dec 2019

Double Trouble: How Children And Adults Decide When To Use Double Consonants, Ruth Caputo

Arts & Sciences Electronic Theses and Dissertations

Consonant doubling is a difficult pattern in the English writing system to master because it is inconsistent. In English two-syllable words, consonants are typically doubled after short vowels, a phonological context, but not after any vowel spelled with more than one letter, a graphotactic context. Knowledge about these contexts may help children learn when to use a single or double consonant. Previous theories on spelling development argue that children learn to spell in stages, without learning about phonological or orthographic context until late in the learning process. This study builds on previous research suggesting that children learn spelling patterns through …


Associations Between Prenatal Selective Serotonin Reuptake Inhibitor Exposure, Depression And Brain Morphology In Middle Childhood, Allison Moreau Dec 2019

Associations Between Prenatal Selective Serotonin Reuptake Inhibitor Exposure, Depression And Brain Morphology In Middle Childhood, Allison Moreau

Arts & Sciences Electronic Theses and Dissertations

Objective: Selective Serotonin Reuptake Inhibitors (SSRIs) are one of the most widely used prescribed medicine by pregnant women. A mixed literature suggests that prenatal SSRI exposure may increase depression risk among offspring. Method: Using data from children (n=11,076) who completed the baseline session of the Adolescent Brain and Cognitive Development (ABCD) study, we examined whether prenatal exposure to SSRIs is associated with child depression and variability in depression-related brain structures (i.e., hippocampus, amygdala, nucleus accumbens, caudate, putamen; rostral anterior cingulate; rostral and caudal middle frontal, superior frontal, and lateral and medical orbitofrontal cortices). Analyses were cross-sectional and included the following …


In Praise Of The Peaks: Science, Art, And Nature In Kojima Usui’S Mountain Literature, Aaron Paul Jasny Aug 2019

In Praise Of The Peaks: Science, Art, And Nature In Kojima Usui’S Mountain Literature, Aaron Paul Jasny

Arts & Sciences Electronic Theses and Dissertations

During the Meiji period (1868–1912), a newly constituted Japanese nation sought equal standing among the global powers it encountered with increasing frequency, by updating and modernizing in various fields of knowledge and cultural production. Science and technology were adopted and adapted from the nations of the West in order to bolster the economy, improve infrastructure, and ensure the health and well-being of the Japanese people. Meanwhile, literature and the arts were refashioned to make them more suitable for dealing with modernization, urbanization, empirical and rational thinking, and a regard for individual autonomy and subjectivity. Meiji Japan witnessed numerous innovations, which …


Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth Aug 2019

Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth

Arts & Sciences Electronic Theses and Dissertations

Recent research has suggested an association between motivational impairment in those with schizophrenia and reduced willingness to expend effort on experimental tasks. However, few studies have examined the neural correlates of effort-based decision-making in those with schizophrenia. In the current study, we aimed to examine willingness to expend effort, the associated neural circuitry of effort-based decision-making, and the impact of experimentally-defined effort-based decision-making on daily motivational experience in schizophrenia. We recruited 28 individuals with schizophrenia and 30 healthy controls to perform an effort-based decision-making task while undergoing fMRI scanning. In order to assess whether willingness to expend effort was associated …

The Afterlife Of Corpses: A Social History Of Unburied Dead Bodies In Qing China (1644-1911), Joohee Suh Aug 2019

The Afterlife Of Corpses: A Social History Of Unburied Dead Bodies In Qing China (1644-1911), Joohee Suh

Arts & Sciences Electronic Theses and Dissertations

This dissertation began with the reading of numerous Qing-dynasty records pertaining to dead bodies that remained on the ground without proper burial. These bodies were not necessarily the victims of extraordinary events such as wars or natural disasters, but the remains of ordinary people whose families failed to arrange a burial site. A wide range of historical materials recorded the presence of these bodies, such as commentaries and critiques on popular burial customs written by the imperial government and literati elites, and Qing popular tales where these bodies were described as man-hunting zombies (jiangshi 僵屍). These sources demonstrate unburied dead …


Scaling-Up Child And Youth Mental Health Services: Assessing Coverage Of A County-Wide Initiative, Cole Douglas Hooley Aug 2019

Scaling-Up Child And Youth Mental Health Services: Assessing Coverage Of A County-Wide Initiative, Cole Douglas Hooley

Arts & Sciences Electronic Theses and Dissertations

Over 7 million children and youth have a diagnosable mental illness any given year. There are evidence-based treatments (EBTs) to effectively treat these conditions, but these EBTs reach a very small percentage of their target population with treatment rates between 1-3%.1 We know very little about what influences these coverage rates. Beginning in 2009, the Los Angeles County Mental Health Department (LACDMH) began an ambitious agenda to scale-up the provision of EBTs in child/youth mental health care. The present study seeks to contribute to the scale-up literature by examining three questions based on LACDMH’s initiative: 1) To what extent have …


Spatial Navigation Ability As A Predictor Of Increased Clinical Impairment, Taylor Hendershott Aug 2019

Spatial Navigation Ability As A Predictor Of Increased Clinical Impairment, Taylor Hendershott

Arts & Sciences Electronic Theses and Dissertations

Spatial navigation deficits are observed in Alzheimer disease (AD) cross-sectionally, but prediction of longitudinal clinical decline has been less examined. Cognitive mapping (CM) was assessed in 95 participants and route Learning (RL) was assessed in 65 participants at baseline. Clinical progression over an average of 4.16 years was assessed using the Clinical Dementia Rating scale. Relative predictive ability of these tasks was compared to episodic memory, hippocampal volume and cerebrospinal fluid (CSF) biomarkers (ptau181/Aβ42 ratio). CM and RL were significant predictors of clinical progression (ps181/Aβ42 in prediction (psTaken together the results suggest that baseline spatial navigation …


Aging Of The Reproductive System And Of Germline Stem Cells In Caenorhabditis, Zuzana Kocsisova Aug 2019

Aging Of The Reproductive System And Of Germline Stem Cells In Caenorhabditis, Zuzana Kocsisova

Arts & Sciences Electronic Theses and Dissertations

C. elegans hermaphrodites display dramatic age-related decline of reproduction early in life while somatic functions are still robust. To understand why the germline fails so early, we analyzed the assembly line of oocyte production that generates fertilized eggs in mated hermaphrodites with sufficient sperm. Aging germlines displayed both sporadic and population-wide changes. A small fraction of aging animals displayed endomitotic oocytes in the germline and other defects. By contrast, all animals displayed age-related decreases in germline size and function. As early as day 3 of adulthood, animals displayed fewer stem cells and a slower cell cycle, which combine to substantially …


Essays On Marketing Strategy, Chang Liu Aug 2019

Essays On Marketing Strategy, Chang Liu

Arts & Sciences Electronic Theses and Dissertations

In this dissertation, I apply game-theoretical methods in the context of marketing research and investigate the effects of stylized facts in behavioral economics. Chapter 1 studies the effects of managerial optimism on firms’ performance. Research has shown that many managers and entrepreneurs tend to be optimistic and are inclined to believe that negative shocks happen to them less frequently than to others. However, there is also evidence suggesting that such optimism is often inaccurate in reality and managerial optimism can lead to the failure of a company. We develop a game-theoretic model to investigate the impact of managerial optimism on …


Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga Aug 2019

Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga

Arts & Sciences Electronic Theses and Dissertations

Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …


The Long-Term Causes And Consequences Of Conflict: A Micro-Level Behavioral Perspective, Joan Barcelo Aug 2019

The Long-Term Causes And Consequences Of Conflict: A Micro-Level Behavioral Perspective, Joan Barcelo

Arts & Sciences Electronic Theses and Dissertations

This dissertation explores the behavioral determinants and legacies of conflict from a socio-psychological perspective. The three papers that compose this dissertation investigate use tools of causal inference to explore, on the one hand, the socialization processes that influence leaders' decision to pursue war-like policies and, on the other hand, the longue durée legacy of wartime violence on preferences, as well as on people's proneness to being swayed by messages of collective threat during conflict. The first paper of the dissertation examines the long-term determinants of interstate conflict by exploring the impact of leader's socialization processes. Based on the soft power …


Isolating Item And Subject Contributions To The Subsequent Memory Effect, Jihyun Cha Aug 2019

Isolating Item And Subject Contributions To The Subsequent Memory Effect, Jihyun Cha

Arts & Sciences Electronic Theses and Dissertations

The subsequent memory effect (SME) refers to the greater brain activation during encoding of subsequently recognized items compared to subsequently forgotten items. Previous literature regarding SME has been primarily focused on identifying the role of specific regions during encoding or factors that potentially modulate the phenomenon. The current dissertation examines the degree to which this phenomenon can be explained by item selection effects; that is, the tendency of some items to be inherently more memorable than others. To estimate the potential contribution of items to SME, I provided participants a fixed set of items during encoding, which allowed me to …


Living In This World: A Social History Of Buddhist Monks And Nuns In Nineteenth-Century Western China, Gilbert Zhe Chen Aug 2019

Living In This World: A Social History Of Buddhist Monks And Nuns In Nineteenth-Century Western China, Gilbert Zhe Chen

Arts & Sciences Electronic Theses and Dissertations

This dissertation relies on about 600 legal cases from the Ba County Archive that survive from the first three-quarters of the nineteenth century to investigate the social life of ordinary Buddhist monks and nuns. Although they played a crucial in maintaining the survival and proper functioning of Buddhism at the local level, they have remained significantly understudied. This dissertation adopts a bottom-up approach to investigate ordinary monastics’ involvement in various socioeconomic activities. By shifting the analytical focus from elite monks to their more mundane counterparts, this study illuminates how deeply ordinary monastics were embedded in their communities. The shift also …


How Specific Is Domain-Specific Slowing? Evidence For A General Form Of A Domain-Specific Mechanism, Cynthia C. Flores Aug 2019

How Specific Is Domain-Specific Slowing? Evidence For A General Form Of A Domain-Specific Mechanism, Cynthia C. Flores

Arts & Sciences Electronic Theses and Dissertations

Faces are special not just because our ability to quickly and accurately process faces is integral for social functioning throughout our lives, but also because faces are considered a unique class of visual stimuli (i.e., faces rely more on holistic processing than objects and there exist specialized, face-specific regions in the brain). Behavioral and neuropsychological research point to face processing as dissociable from other kinds of visuospatial processing. Although there is evidence that neural specificity for faces is retained in older adults, there is also evidence that age-related impairments are greater in face processing, relative to object processing. Using a …


Medical Aid In Dying: Knowledge, Attitudes, And Beliefs Of Licensed Psychologists, Christine Caroline Merz Aug 2019

Medical Aid In Dying: Knowledge, Attitudes, And Beliefs Of Licensed Psychologists, Christine Caroline Merz

Arts & Sciences Electronic Theses and Dissertations

Medical aid in dying (MAID) is a process by which individuals with terminal illness can voluntarily ingest a lethal dose of medication provided to them by their physician to intentionally end their life. MAID is currently legal in eight U.S. states and several other countries. Licensed psychologists and other mental health professionals are implicated in MAID laws in the form of psychological evaluation that is required for select patients. Little is known about the knowledge and attitudes of psychologists regarding MAID, including views on legal and ethical acceptability, and professional competence to conduct psychological evaluations for patients requesting MAID. The …


Affective Materiality: Latin American Science Fiction At The Turn Of The Twenty-First Century, Kyeongeun Park Aug 2019

Affective Materiality: Latin American Science Fiction At The Turn Of The Twenty-First Century, Kyeongeun Park

Arts & Sciences Electronic Theses and Dissertations

This dissertation explores diverse shapes of the future as represented in literary production at the turn of the century—from the late 1980s to the present day—through examining the science fiction (sf) of Argentina, Chile, and Mexico. I focus primarily on materiality as an actor and on the agency of things in dialogue with human society through an investigation of the material and cultural productions of sf texts by further scrutinizing the impact of new networking technology. While analyzing the absence and presence of material culture and technological ecology in the selected texts, I work to identify the unique shades and …


Caseworker Turnover In Foster Care Services: Problem Or Symptom? A System Dynamics Approach, Marian Joan Stahlschmidt Aug 2019

Caseworker Turnover In Foster Care Services: Problem Or Symptom? A System Dynamics Approach, Marian Joan Stahlschmidt

Arts & Sciences Electronic Theses and Dissertations

Problem: Child welfare (CW) caseworkers perform a crucial role in our society--ensuring the safety, permanency, and well-being of one of our most vulnerable populations, victims of child maltreatment. Yet, since its inception in the early 20th century, CW, including foster care services, has been plagued by high turnover rates that have been associated with delayed permanency and recurrent maltreatment. This dissertation aimed to develop a dynamic hypothesis about the system structure that produces turnover in foster care services, to create a formal system dynamics simulation model representing the problem, to develop an intervention to reduce the problem, and to test …


Task-Evoked Pupillary Response For Completely Intelligible Accented Speech, Drew Mclaughlin Aug 2019

Task-Evoked Pupillary Response For Completely Intelligible Accented Speech, Drew Mclaughlin

Arts & Sciences Electronic Theses and Dissertations

Speech perception under adverse conditions, such as those caused by noise in the environment or a speaker’s accent, can be cognitively demanding. For second language- (L2-) accented speech, mismatches between the speech patterns of an L2-accented speaker and a listener can result in poorer understanding and reduced intelligibility (i.e., fewer words in the speech stream can be correctly identified). However, it remains unclear whether completely intelligible L2-accented speech imposes greater cognitive load (defined here as the degree to which cognitive resources are recruited at a given moment to meet processing demands) than native speech. In the current study, we used …
