Study Design. The test phase included four runs of 10 fear and 10 neutral trials, for a total of 40 fear trials and 40 neutral trials. Each trial consisted of a cue (1s), an anticipation period (5-9s), and a face (1s). Following each trial, a 5-9s blank screen was shown to allow for return to baseline. Fear and neutral trials were randomized within runs and the duration of the anticipation period was jittered between trials.
