Does Resilience Moderate The Impact Of Children’S Experiences Of Racial And Ethnic Discrimination On Internalizing Problems?, Dahlia Abbas
Does Resilience Moderate The Impact Of Children’S Experiences Of Racial And Ethnic Discrimination On Internalizing Problems?, Dahlia Abbas
Dissertations and Theses
This study’s objectives were to investigate how children’s experiences of discrimination impact the severity of their internalizing symptoms, and whether the relation between discrimination and internalizing symptom severity is moderated by resilience. It was predicted that children who had experienced more discrimination would have more severe internalizing symptoms, especially when they have low levels of resilience. Children [N=20; Mean (SD) age= 11.83 (2.50)] receiving low-cost music lessons in northern Manhattan were recruited into a larger study examining how learning music affects cognitive and emotional development. Children were interviewed in-person about experiences of discrimination because of their race/ethnicity using the Perceptions …
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
Competition Between Veridical And Perceived Location For Visuomotor Control, Fatemeh Alhabib
Competition Between Veridical And Perceived Location For Visuomotor Control, Fatemeh Alhabib
Dissertations and Theses
An influential proposal holds that our visual systems use different information for perception and action. Though numerous studies utilized visual illusions, in which veridical and perceptual properties of objects differ, the evidence was inconclusive and no consensus was reached. In response priming, some evidence suggests that only physical attributes of the prime stimuli control motor responses. Across two experiments, we examined the contributions of physical and consciously perceived location to response priming, using a well-known flash-lag illusion, in which a briefly flashed disk and the moving bars appearing at the same location are perceived as displaced. In all experiments, participants …

Mild Traumatic Brain Injuries And Their Implications On Changes In Event Related Potentials: A Look Into Visual Gating (P50), Katelynn M. Kozak
Dissertations and Theses
Concussions are a prevalent injury that affect a wide range of individuals. Commonly seen amongst individuals who play contact sports, there are many underlying factors that doctors and clinicians have yet to understand which include properties such as proper diagnosis standards or lasting impacts. In this study, we look at those impacts by using electroencephalographic (EEG) measures to study the changes in event related potentials (ERPs) associated with sensory gating and how this cognitive property is affected in those who have a self-reported concussion. Here we show that a visual attention and gating mechanism exists in both populations (control and …
