abstract

  • The P300 component of the event-related brain potential (ERP) was elicited with auditory stimuli in two different tasks. The oddball paradigm presented both target and standard stimuli; the single-stimulus paradigm presented a target but no standard tone stimulus, with the inter-target interval the same as that for the oddball condition. Experiment 1 manipulated stimulus intensity and Experiment 2 manipulated tone stimulus frequency, with the relative target probability maintained 0.20 for both tasks. P300 amplitude and latency were highly similar for the oddball and single-stimulus procedures in both experiments across independent variables. The findings suggest that the single-stimulus paradigm may prove useful in experimental and applied contexts that require very simple ERP task conditions.
