We report two experiments that investigated factors that might boost 'episodic' recall for Jon, a developmental amnesic whose episodic memory is gravely impaired but whose semantic memory seems relatively normal. Experiment 1 showed that Jon's recall improved following a semantic study task compared with a non-semantic study task, as well as following four repeated study trials compared with only one. Experiment 2 additionally revealed that Jon's recall improved after acting compared with reading action phrases at study, but only if the phrases were well integrated semantically. The results provide some support for the hypothesis that Jon's 'episodic' recall depends on the extent to which he is able to retrieve events using semantic memory.
我们报告了两项实验，这些实验探究了可能提高琼 episodic 记忆的因素。琼是一名发展性失忆症患者，其 episodic 记忆严重受损，但语义记忆似乎相对正常。实验1表明，与非语义学习任务相比，语义学习任务后琼的回忆有所改善；与仅进行一次学习试验相比，进行四次重复学习试验后琼的回忆也有所改善。实验2还表明，与在学习时阅读动作短语相比，表演后琼的回忆有所改善，但前提是这些短语在语义上有很好的整合。这些结果为以下假设提供了一些支持，即琼的“episodic”回忆取决于他能够利用语义记忆检索事件的程度。
