Personality Pathology And Cognitive Aging: The Role Of Interpersonal Stress, Patrick Joseph Cruitt Aug 2021

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 Aug 2021

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) …


A Secondary Data Analysis Of The Prevalence Of Reported Dementia And Subjective Cognitive Decline Across U.S. National Surveys, Matthew C. Picchiello Aug 2021

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 …


Fearful Versus Dismissive Beliefs About Emotion: Divergent Pathways To Non-Acceptance Of Emotion, Natasha Haradhvala Bailen May 2021

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 …


Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff Apr 2021

Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff

Arts & Sciences Electronic Theses and Dissertations

Phenylketonuria (PKU) is an autosomal recessive disorder characterized by mutations in phenylalanine hydroxylase genes. As a result, phenylalanine (Phe) metabolism is disrupted, and this amino acid accumulates in blood and tissue (Pietz, 1998; Scriver et al., 2000). Although the most severe symptoms of PKU may be avoided by early detection and treatment, many individuals with early-treated PKU still experience difficulties in executive function, attention, and processing speed (Antenor-Dorsey et al., 2013; Araujo et al., 2013; Christ et al., 2020; Hawks, Strube, Johnson, Grange, & White, 2018; Hood, Grange, Christ, Steiner, & White, 2014; Janos et al., 2012; White et al., …


Social And Non-Social Pleasure In Schizophrenia: Associations With Negative Symptoms And Depression, Jaisal Merchant Jan 2021

Social And Non-Social Pleasure In Schizophrenia: Associations With Negative Symptoms And Depression, Jaisal Merchant

Arts & Sciences Electronic Theses and Dissertations

Individuals with schizophrenia can experience both negative and depressive symptoms, which may differentially relate to hedonic experience. Additionally, it is unclear whether these symptoms relate to social pleasure in the same way as overall pleasure. This study used Ecological Momentary Assessment in schizophrenia to investigate the unique relationships of negative and depressive symptoms to anticipatory and consummatory pleasure overall, and when split into social and non-social instances. Depressive symptoms negatively related to both anticipatory and consummatory pleasure, while negative symptoms negatively related to anticipatory but not consummatory pleasure. Although negative symptoms negatively related to both anticipatory and consummatory non-social pleasure, …
