在2个实验中，我们评估了健忘症患者在单次接触图片后表现出持久知觉启动的能力。学生在一个单一的场合尽可能快地命名图片，后来命名相同的图片与新的图片混合。在实验1中，健忘症患者表现出完全完整的启动效应持续至少7天。在实验2中，两组的启动效应被证明是依赖于高度具体的视觉信息和视觉上少，更多的概念性信息。与此相反，识别记忆严重受损的患者，评估的准确性和反应时间。结果提供了第一份报告的持久启动效应在健忘症患者，基于一个单一的遭遇，这发生在患者中的强烈，在正常的SS。以及其他最近的发现。结果表明，持久的启动和识别记忆依赖于不同的大脑系统。
In 2 experiments, we evaluated the ability of amnesic patients to exhibit long-lasting perceptual priming after a single exposure to pictures. Ss named pictures as quickly as possible on a single occasion, and later named the same pictures mixed with new pictures. In Experiment 1, amnesic patients exhibited fully intact priming effects lasting at least 7 days. In Experiment 2, the priming effect for both groups was shown to depend on both highly specific visual information and on less visual, more conceptual information. In contrast, recognition memory was severely impaired in the patients, as assessed by both accuracy and response time. The results provide the first report of a long-lasting priming effect in amnesic patients, based on a single encounter, which occurs as strongly in the patients as in normal Ss. Together with other recent findings. the results suggest that long-lasting priming and recognition memory depend on separate brain systems.
