Objective To explore the processing mechanism of human brain for task related and stimulus related conflicts.Method Subjects counted the times of identical and different stimulus pairs separately while event related potentials(ERPs)were recorded from their scalps.The stimulus pairs can be divided into four conditions:no conflict ,stimulus related conflict,task related conflict,and both stimulus related and task related conflict.Result An N270 was evoked by all the stimulus pairs that contained conflict but not by the no conflict pairs.There were no significant differences in the onset latencies and the terminations of N270 among the three kinds of conflict.Conclusion The human brain processes stimulus related and task related conflicts in parallel.
