Antisocial Behavior And Callous Unemotional Traits In Youth: A Biosocial Approach, Yong Lin Huang
Antisocial Behavior And Callous Unemotional Traits In Youth: A Biosocial Approach, Yong Lin Huang
Dissertations, Theses, and Capstone Projects
Early life presence of antisocial behavior (e.g., aggression/delinquency) and psychopathic/callous-unemotional (CU) traits (lacking empathy/remorse, shallow affect) are precursors to juvenile crime and criminal offending in adulthood. Etiological research on antisocial/CU tendencies has implicated both neurobiological (e.g., alterations in brain function and structure) and environmental (social adversity, prenatal stress) underpinnings. It has been proposed that reward and punishment processing deficits may induce problematic traits and behavior, such that antisocial/CU tendencies may be linked to hypersensitivity to rewards and hyposensitivity to punishment. Studies in this area have generated inconsistent findings and focused primarily on adult and clinical samples, leaving youth and community …
Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia
Dissertations, Theses, and Capstone Projects
Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …
