采用听觉和视觉刺激的刺激序列范式，分别在主动和被动任务反应条件下诱发P300事件相关脑电位（ERP）。被动任务中的听觉刺激产生的P300波形与主动任务条件下获得的波形相似。被动任务中的视觉刺激产生的P300波形要小得多，这些波形在形态上与主动任务中的波形不一致。结果表明，在被动任务情境中，听觉刺激比视觉刺激产生更强的P300成分。(C)1999 Elsevier Science B.V.保留所有权利。
The P300 event-related brain potential (ERP) was elicited with a stimulus-sequence paradigm for auditory and visual stimuli in separate active and passive task response conditions. Auditory stimuli in the passive task yielded P300 waveforms similar to those obtained from the active task condition. Visual stimuli in the passive task yielded much smaller P300 waveforms that were not morphologically consistent with those from the active task. The results suggest that auditory stimuli produce more robust P300 components than visual stimuli in passive task situations. (C) 1999 Elsevier Science B.V. All rights reserved.
