Escalating Risk And The Moderating Effect Of Resistance To Peer Influence On The P200 And Feedback-Related Negativity, John Kiat, Elizabeth Straley, Jacob Cheadle

Department of Psychology: Dissertations, Theses, and Student Research

Young people frequently socialize together in contexts that encourage risky decision making, pointing to a need for research into how susceptibility to peer influence is related to individual differences in the neural processing of decisions during sequentially escalating risk. We applied a novel analytic approach to analyze EEG activity from college-going students while they completed the Balloon Analogue Risk Task (BART), a well-established risk-taking propensity assessment. By modeling outcome-processing-related changes in the P200 and feedback-related negativity (FRN) sequentially within each BART trial as a function of pump order as an index of increasing risk, our results suggest that analyzing the …

An Exploratory High-Density Eeg Investigation Of The Misinformation Effect: Attentional And Recollective Differences Between True And False Perceptual Memories, John E. Kiat, Robert F. Belli

The misinformation effect, a phenomenon in which eyewitness memories are altered via exposure to post-event misinformation, is one of the most important paradigms used to investigate the reconstructive nature of human memory. The aim of this study was to use the misinformation effect paradigm to investigate differences in attentional and recollective processing between true and false event memories. Nineteen participants completed a variant of the misinformation paradigm in which recognition responses to true and misinformation based event details embedded within a narrative context, were investigated using high-density (256-channel) EEG with a 1-day delay between event exposure and test.
