Frontal Alpha Wave Asymmetry In Regard To Affect, Monica Leigh Sewell Jan 2021

Frontal Alpha Wave Asymmetry In Regard To Affect, Monica Leigh Sewell

All Master's Theses

This study examines frontal alpha brain wave asymmetry (FAA) in relation to emotion processing. Previous research has shown that differences between left versus right FAA could exhibit a neurological marker for emotional intelligence (EI), mental health, and stress. Behavioral data were collected using Profile of Emotional Competence Questionnaire, Perceived Stress Questionnaire, Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7. This was followed by a series of resting EEG recordings. This study hypothesizes that participants who are mentally healthy, have higher EI scores and lower stress will display greater left FAA. The hypothesis is partially supported; participants with depression had greater …

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref Jan 2020

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 …
