The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen
The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen
Masters Theses
Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) …

Children's Self-Regulation During Reward Delay, Abigail Fontaine
Masters Theses
Individuals who display high levels of reward sensitivity are motivated by and respond to reward related cues, thus exhibiting more approach-motivated behaviors. A majority of the research on physiological indices of reward sensitivity in relation to self-regulatory abilities has focused on adults or adolescents, with relatively little work examining these associations in children. Thus, the current study sought to examine whether a common neural measure of reward sensitivity, left frontal electroencephalogram (EEG) asymmetry, assessed in early childhood was predictive of children’s later self-regulation abilities in the context of reward delay. Emerging inhibitory control skills were also examined as a potential …
