Figure 1. Go/NoGo task.

Figure 1

Response inhibition was measured using the Go/NoGo task that followed previous work by Leibenluft et al. (2007). On Go trials, a white X or O appeared on a black background for 1000ms. Participants were instructed to respond as fast as possible to this Go trial by pressing a 1 for X and 2 for O. However, one third of the trials was a NoGo trial (indicated by a red rectangle behind X or O), and participants were instructed to withhold their response. The stimulus event was followed by a jittered inter-trial interval ranging from 1250 to 2500ms, and a 500ms white fixation cross. The task consisted of 4 runs separated by three 30s rest periods. Each run comprised 26 “Go” trials, 13 “NoGo” trials, and 14 blank trials distributed randomly. Response inhibition was measured by subtracting correct Go trials from correct NoGo trials.
