Embodiment, Relationality and a New Morality
(Georgetown University, 2014)
EMBODIMENT, RELATIONALITY AND A NEW MORALITY
Interaction of Attention and Emotion Across Development and Disorder
(Georgetown University, 2012)
This dissertation examines how attention and emotion interact in early visual processing across typical development and in Attention Deficit/Hyperactivity Disorder (ADHD). To investigate early visual processing, we utilized ...
Readiness to learn: Characteristics associated with implicit learning aptitude
(Georgetown University, 2015)
Cognitive frailty is one of the biggest threats to healthy aging, and yet our basic understanding of cognitive aging is limited in at least two ways. First, while group differences in the cognitive performance of younger ...
An Investigation of Working Memory: Influences of COMT, Sex, and Urbanicity on Cognitive Performance and Neuroimaging Measures
(Georgetown University, 2014)
Working memory is involved in numerous areas of cognition. It has been studied using various tasks, in which cognitive performance and brain activation have been measured. Working memory depends largely on dopamine ...
Neurocognitive Deficits In Pediatric Obesity
(Georgetown University, 2017)
In the United States, 20% of adolescents suffer from obesity (body mass index—BMI—above the 95th percentile) and 8% of adolescents suffer from severe obesity (BMI 120% above the 95th percentile). Obesity carries increased ...
The Effects of Extensive Single Task and Dual Task Training on the Neural Bases of Visual Object Categorization: Escaping the Frontal Bottleneck
(Georgetown University, 2017)
Perceptual learning of visual categorization has been described as a two-stage model, wherein the tuning of representations in visual areas is sharpened to the physical attributes of the stimuli and dorsolateral prefrontal ...
The Relationship Between the Perception of Unexpected Harmonic Events and Preference in Music
(Georgetown University, 2018)
Music cognition researchers have proposed a relationship between the perception of unexpected harmonic events and preference in music. The brain strategies underlying this relationship, however, have not been substantially ...
Investigating the Relationship between Long Chain Omega-3 Fatty Acids and Prefrontal Cortex Development during Adolescence
(Georgetown University, 2017)
Delivery of building blocks essential for brain development is critical for the normal development of the brain and behavior. Omega-3 (N3) fatty acids are essential nutrients, which can only be obtained from the diet. ...
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 ...
Mapping the Neurocognitive Architecture of Reading
(Georgetown University, 2021)
Reading relies on at least partially dissociable sub-word (sublexical) and word-specific (lexical) processes, which are subserved by somewhat separable neural substrates. Beyond this broad dissociation between sublexical ...
