The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker
The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker
Dissertations & Theses (Open Access)
Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …
Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna
Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna
Electronic Theses and Dissertations
Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social …
Biobehavioral Predictors Of Cannabis Use In Adolescence, Philip Aaron Spechler
Biobehavioral Predictors Of Cannabis Use In Adolescence, Philip Aaron Spechler
Graduate College Dissertations and Theses
Cannabis use initiated during adolescence may precipitate lasting consequences on the brain and behavioral health of the individual. However, research on the risk factors for cannabis use during adolescence has been largely cross-sectional in design. Despite the few prospective studies, even less is known about the neurobiological predictors. This dissertation improves on the extant literature by leveraging a large longitudinal study to uncover the predictors of cannabis use in adolescent samples collected prior to exposure. All data were drawn from the IMAGEN study and contained a large sample of adolescents studied at age 14 (N=2,224), and followed up at age …
Risk Profiles For Adolescent Internalizing Problems, Kelsey Elizabeth Hudson
Risk Profiles For Adolescent Internalizing Problems, Kelsey Elizabeth Hudson
Graduate College Dissertations and Theses
Objective: Internalizing problems are commonly diagnosed during adolescence, and are associated with distress, impairment, and negative mental health outcomes in adulthood. Thus, there is a critical need to characterize adolescents who are at the highest risk for escalating to clinical levels of internalizing problems while extending current literature and incorporating both biological and environmental predictors. This study aimed to characterized risk profiles for fourteen-year-old adolescents who developed clinical levels of internalizing (High Internalizing [HI]) problems by age nineteen, using brain, genetic, personality, cognitive, life history, psychopathology, and demographic measures. The study also examined whether there were functional and structural brain …
