Subject: fMRI Study: Participants Needed Description: The Laboratory of Cognition and Emotion led by Dr. Pessoa is looking for participants in a brain scan (fMRI) study we are currently conducting. The study is a visual discrimination task that involves "highly unpleasant but not painful" electric stimulation to the fingertips during the scan. All participants will set their own maximum level of electric stimulation. The scan takes place at the Maryland Neuroimaging Center, which is right off campus. The scan lasts 75 minutes, with a total experiment time of approximately 1 hr and 45 minutes. Compensation is $30/hour during the scan. To be eligible for the study, participants must: be 18-40; be right-handed; not have metal anywhere in the body; not wear glasses (contacts are fine); not have any history of neurological or psychological problems or be on any psychoactive medications or drugs; not be claustrophobic or color-blind; not be pregnant or have heart disease; not have participated in any studies that involves looking at faces.
