We measured the change of ERP during Filtering Paradigm and Selective-set Paradigm. From experiments using these paradigms, we found P300. For the former stimulus, N1 peak potential in ERP increased and the lead position on the scalp changed by the direction of target stimulus. For the latter stimulus, P1 peak potential in ERP increased by the position of target stimulus. From these results, ERP is useful index to measure the response to human attention positions.
