Objective To explore the processing mechanism of human brain for spatial location c onflicts.Method Sixteen normal adults participated in the matching-to-sa mple task.They were asked to discrim inate if the position of the two visual stimulus presented in sequence were identical and event-related potential(ERP)was recorded from their scalp.Results A N270was evoked by the position conf licting stimulus pairs but not by the positio n matching pairs.N270was mainly dis tributed at posterior areas.Conclusion N270can be elicited by spatial location conflict.
