Project title: Impact of Stress on the EEG Correlates of Human Decision-Making

Department: Exercise Science, Physical and Health Education

Faculty supervisor: Dr. Olav Krigolson

"It is well known that stress impacts our behaviour in a variety of ways. Here, I will examine how acute and chronic stress impacts human decision-making. More specifically, I will examine how acute and chronic stress impacts the EEG (or brain wave) correlates associated with Type I and Type II decision-making during performance of a medical decision-making task. I predict that both acute and chronic stress will result in slower reaction times and more decision errors. Further, I predict that acute and chronic stress will reduce frontal EEG power in the theta band (executive control) and posterior EEG power in the alpha band (attention)."
