Abstract The effects of time pressure (TP) on sequential effects in Simon task were investigated using the stimulus locked lateralized readiness potential (LRP), response locked LRP and P300. These event-related potentials (ERPs) were recorded from participants performing a visual Simon task. In this task, participants had to press the left key when an "F" was presented, and the right key when a "J" was presented. The side of the stimulus and the required response side could be compatible or incompatible. TP was manipulated by using moderate or severe response time limits. Reaction times (RTs), stimulus locked LRP latencies and P300 latencies for incompatible stimuli were longer than for compatible stimuli. These Simon effects were observed only when the stimuli followed a compatible trial but not after a incompatible trial. Moreover, initial incorrect activities in stimulus locked LRP were larger after compatible trial than after incompatible trial. These sequential effects in Simon task were not modulated by TP. These results suggest that the cognitive control which suppresses an automatic response is exerted over both stimulus evaluation process and response selection process regardless of the degree of TP.
