比较被动纯音序列和主动听觉辨别任务诱发的P300（P3）事件相关电位。每个刺激的情况下，连续重复研究重复效果。第一个刺激的音调序列产生一个积极的电位与头皮分布和峰值潜伏期类似的P3从主动歧视任务，虽然其幅度小于从主动范式获得的。第一组试验表明，序列和歧视任务之间的P3潜伏期和振幅的最强相关性。结果表明，被动声调序列范式可能提供P3措施，接近那些从主动辨别任务。
The P300 (P3) event-related potential elicited with a passive tone sequence paradigm was compared with an active auditory discrimination task. Each stimulus situation was replicated successively to study repetition effects. The first stimulus of the tone sequence produced a positive-going potential with a scalp distribution and peak latency similar to the P3 from the active discrimination task, although its amplitude was smaller than that obtained from the active paradigm. The first block of trials demonstrated the strongest correlations for both P3 latency and amplitude between the sequence and discrimination tasks. The results suggest that the passive tone sequence paradigm may provide P3 measures which approximate those acquired from an active discrimination task.
