EEG: Probabilistic Selection Task (PST) + PST with Cabergoline Challenge

This dataset comprises EEG recordings from two studies using a Probabilistic Selection Task (PST): Study 1 includes 85 participants (80 healthy controls plus 5 pilot placebo sessions), and Study 2 includes 27 healthy participants (after 3 dropouts from initial 30) in a double-blind design receiving either Cabergoline 1.25 mg or placebo. The dataset was collected circa 2012-2013 at Brown University's Laboratory for Neural Computation & Cognition and provides neurophysiological measures of decision-making and reward processing during probabilistic learning. NOTE: This dataset is unpublished; however, the same sample was used in the published study (10.1038/ncomms6394). Known issues: Subject 173 may have poor EEG data quality. Event file feedback labels ('FB: 0' and 'FB: +1') do not match actual task feedback ('Correct!' or 'Incorrect!'); see stimuli folder for accurate feedback labels. Original task description contained mislabeling as 'Simon Conflict' task; this is a Probabilistic Selection Task (PST).
