Group type: PLACEBO_COMPARATOR
Intervention: Inhibitory task
Description: Participants perform a binary decision on each presented stimuli. Of the two possible outcomes, participants are instructed to make a motor response (go) for one type, and are to withhold a response (no-go) for the other type. Reaction time and accuracy are measured for each event
