Correct responses to go stimuli had a mean reaction time (RT) of 445.06 ms (SD = 75.63 ms), while incorrect responses to no-go stimuli (false alarms) had a mean RT of 451.89 ms (SD = 104.49). Since the number of go and no-go stimulus were different, accuracy rates were calculated within each stimulus type (i.e., sum of correct omissions/sum of no-go trials, and sum of correct commissions/sum of go trials). The mean ratio of correct responses in the go condition was 97.45% (SD = 2.98), while the mean ratio of correct omissions for the no-go condition was 76.64% (SD = 15.00), indicating that participants performed fairly well, although the no-go condition may have been more difficult.
