Illustration of the coin flip task. For each trial, there was a 2s presentation period, followed by a 3.75s response period. To signal the beginning of the response period, the options appeared on the bottom of the screen as 1= gamble (i.e., accept) or 2= don’t gamble (i.e., reject). Inter-trial intervals (ITI) ranged 2–8s (M= 3.31).
