Priming and recollection are expressions of human memory mediated by different brain events. These brain events were monitored while people discriminated words from nonwords. Mean response latencies were shorter for words that appeared in an earlier study phase than for new words. This priming effect was reduced when the letters of words in study-phase presentations were presented individually in succession as opposed to together as complete words. Based on this outcome, visual word-form priming was linked to a brain potential recorded from the scalp over the occipital lobe about 450 ms after word onset. This potential differed from another potential previously associated with recollection, suggesting that distinct operations associated with these two types of memory can be monitored at the precise time that they occur in the human brain.
启动效应和回忆是由不同脑活动介导的人类记忆的表现形式。在人们区分单词和非单词时，对这些脑活动进行了监测。与新单词相比，出现在早期学习阶段的单词的平均反应潜伏期更短。当学习阶段呈现的单词字母是逐个连续呈现而不是作为完整单词一起呈现时，这种启动效应会减弱。基于这一结果，视觉词形启动效应与单词出现后约450毫秒在枕叶上方头皮记录到的脑电活动相关。这种脑电活动与先前与回忆相关的另一种脑电活动不同，这表明与这两种记忆类型相关的不同操作可以在它们在人脑中发生的精确时间进行监测。
