A technique for measuring the latency of the P300 component of event-related brain potentials on individual trials is described. Choice reaction times and the latency of the P300 were compared under speed-maximizing and under accuracy-mazimising instructions. The choice stimuli required different levels of semantic categorization. The data support the proposition that the latency of P300 corresponds to stimulus evaluation time and is independent of response selection.
本文描述了一种在个体试验中测量事件相关脑电位P300成分潜伏期的技术。在速度最大化和准确性最大化的指令下，比较了选择反应时和P300的潜伏期。选择刺激需要不同程度的语义分类。数据支持以下观点：P300的潜伏期对应于刺激评估时间，且与反应选择无关。
