Clear Adjustment: Status Self-Concept Clarity And Emotion Regulation, Isidro Landa
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 …
Person-Centered Profile Consistency: A Test Of Longitudinal Personality Consistency, Amanda Wright
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 …
Emotion Differentiation Moderates The Effects Of Rumination On Depression: A Longitudinal Study, Yunjing Liu
Emotion Differentiation Moderates The Effects Of Rumination On Depression: A Longitudinal Study, Yunjing Liu
Arts & Sciences Electronic Theses and Dissertations
Elevated trait rumination is associated with and predicts the onset of major depressive disorder (MDD), but not all people with elevated trait rumination develop MDD. We hypothesize that certain emotional processes weaken the rumination-depression link, protecting people against increases in depression. In the current prospective longitudinal study, we examined one such process, emotion differentiation—the ability to identify and label specific emotions. Because higher negative emotion differentiation (NED) has been associated with greater psychological well-being and people typically ruminate in the context of negative affect, we predicted that NED, but not positive emotion differentiation (PED), would moderate the rumination-depression association, such …
Neurogenetics Of The Externalizing Spectrum, Caitlin E. Carey
Neurogenetics Of The Externalizing Spectrum, Caitlin E. Carey
Arts & Sciences Electronic Theses and Dissertations
Externalizing spectrum disorders, which include attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, alcohol and substance use disorders, and antisocial personality disorder, are characterized by behavioral disinhibition and are thought to be manifestations of a common heritable liability factor throughout the lifespan. However, relatively little is known about their underlying etiology. Here, I probe genetic and neural risk mechanisms for externalizing psychopathology in three complementary studies. First, I report an indirect association between genetic risk for childhood attention-deficit/hyperactivity disorder (ADHD) and problem drinking in young adulthood, mediated by heightened reward-related neural activity within the ventral striatum, among 404 college students. I …
Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks
Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks
Arts & Sciences Electronic Theses and Dissertations
Phenylketonuria (PKU) is a recessive disorder characterized by disruption in the metabolism of the amino acid phenylalanine. Using a verbal fluency task, previous studies demonstrated that word production is reduced in individuals with PKU relative to controls. Beyond word production, verbal fluency output can be scored for clustering and switching, which enable characterization of verbal and executive processes, respectively. The present study is the first to evaluate clustering and switching in PKU within a longitudinal design, thereby elucidating the developmental time course of core cognitive processes. To this end, semantic (animals, food/drink) and phonemic (S words, F words) fluency data …
