启动是一种无意识的（非陈述性的）记忆形式，通过早期的接触来提高对物品的识别或生产。有人提出陈述性记忆和启动可能是相关的，例如，概念启动导致更流畅的加工，从而为熟悉度判断提供了基础。在两个实验中，我们评估了5名记忆受损患者的概念启动和识别记忆。所有患者在自由联想（研究帐篷；在测试中，提供与画布的关联）和类别验证（研究柠檬；在测试中，决定：柠檬是一种水果吗？）的测试中都表现出完全完整的启动。然而，两名最严重的失忆症患者在识别记忆的匹配测试中表现偶然。这些发现反驳了概念启动提供熟悉感的观点，这种感觉可以支持准确的识别判断。我们认为，启动对有意识的意识是不可接近的，并且不影响陈述性记忆。
Priming is an unconscious (nondeclarative) form of memory whereby identification or production of an item is improved by an earlier encounter. It has been proposed that declarative memory and priming might be related-for example, that conceptual priming results in more fluent processing, thereby providing a basis for familiarity judgments. In two experiments, we assessed conceptual priming and recognition memory across a 5-min interval in 5 memory-impaired patients. All patients exhibited fully intact priming in tests of both free association (study tent; at test, provide an association to canvas) and category verification (study lemon; at test, decide: Is lemon a type of fruit?). Yet the 2 most severely amnesic patients performed at chance on matched tests of recognition memory. These findings count against the notion that conceptual priming provides feelings of familiarity that can support accurate recognition judgments. We suggest that priming is inaccessible to conscious awareness and does not influence declarative memory.
