Adolescent Neurocognitive Maturity Mediates Paths to Altered Social Norms and Vulnerability in Emerging Adulthood
(Georgetown University, 2020)The transitional period between adolescence and adulthood is a high-risk period for social strain and adversity leading to experiences of violence and altered normative civic beliefs. In this dissertation, I examine cognitive ... -
The Behavioral and Neural Basis of Emotional Face Processing in Atypically Developing Children and Adolescents
(Georgetown University, 2014)The ability to recognize, interpret, and respond appropriately to the affective facial expressions of others is an important component of non-verbal communication; when face-emotion recognition is impaired there can be ... -
THE EFFECTS OF ROBOTIC TRAINING AND CORTICAL STIMULATION ON REACHING SKILL AFTER CHRONIC STROKE
(Georgetown University, 2011)<bold>BACKGROUND: </bold> Reaching in three dimensional (3D) space, crucial for activities of daily living (ADLs), is deficient after stroke. The effects of cortical stimulation on 3D robotic training for patients with ... -
Genetic Influences of Dopamine and GABA on Adolescent Cognition
(Georgetown University, 2018)Adolescence is a time of exploration, but also risk taking, such as alcohol use. What places individuals’ at risk has not been fully elucidated. Twin studies of adult alcohol use disorders (AUD’s) found genetics account ... -
INVESTIGATING THE CHOLINERGIC REGULATION OF HUMAN LEARNING AND MEMORY USING FUNCTIONAL MAGNETIC RESONANCE SPECTROSCOPY
(Georgetown University, 2016)Current theories consider the effects of acetylcholine neuromodulation in neuronal ensembles as a bidirectional network modulator: increased levels set network dynamics to process external stimuli, and decreased levels set ... -
Reproducibility and use of myelin imaging methods for the study of adolescent brain development
(Georgetown University, 2017)Human brains have few myelinated axons at birth and continue to myelinate along a temporal and regional specific pattern into adulthood. This prolonged growth trajectory not only contributes to adaptability in functional ...
