An electrical response of the brain to recognizable images was described. The response (referred to as the "recognition potential") occurred for words, pictures, and faces, but not for non-meaningful control images. It was best recorded from the occipital area. The peak latency was 200-250 ms. It differed from the P300 response in latency, topography, and sensitivity to probability of occurrence. Its amplitude depended on the site of recording and the visual field stimulated. Degradation of the images caused equal increases in reaction time (RT) and recognition potential latency. The results contradicted the proposal that the latency of the P300 can be used as a measure of the timing of stimulus evaluation processes.
文中描述了大脑对可识别图像的电反应。这种反应（称为“识别电位”）出现在单词、图片和面部图像出现时，而无意义的对照图像则不会引发该反应。该反应在枕叶区域记录效果最佳。峰值潜伏期为200 - 250毫秒。它在潜伏期、地形图以及对出现概率的敏感性方面与P300反应有所不同。其振幅取决于记录部位和受刺激的视野。图像质量下降会导致反应时间（RT）和识别电位潜伏期同等增加。这些结果与P300潜伏期可作为刺激评估过程时间测量指标的提议相矛盾。
