Amnesic patients were studied to determine whether the acquisition and retention of item-specific skills can be supported by nondeclarative (implicit) memory. In Experiment 1, subjects read 2 different passages 3 times in succession. Reading speed improved at a similar rate in both amnesic patients and normal subjects and was specific to the text that was read. In Experiment 2, amnesic patients and normal subjects read a passage 3 successive times and then reread the same passage after a 0-s, 10-min, 2-hr, or 1-day delay. In both groups, facilitation persisted for at least 10 min and disappeared within 2 hr. It is suggested that facilitated reading speed depends importantly on both semantic and perceptual information and that such information can be supported by nondeclarative memory.
对遗忘症患者进行了研究，以确定特定项目技能的习得和保持是否可以由非陈述性（隐性）记忆来支持。在实验1中，受试者连续3次阅读2篇不同的文章。遗忘症患者和正常受试者的阅读速度以相似的速率提高，并且是特定于所阅读的文本的。在实验2中，遗忘症患者和正常受试者连续3次阅读一篇文章，然后在延迟0秒、10分钟、2小时或1天后再次阅读同一篇文章。在两组中，阅读速度的促进至少持续10分钟，并在2小时内消失。研究表明，阅读速度的提高在很大程度上依赖于语义和感知信息，并且这种信息可以由非陈述性记忆来支持。
