1976年，一名脑炎导致的健忘症患者被描述为具有正常的短期记忆和完整的语义分析能力。尽管有这种能力，但他的记忆力几乎为零，超过了短期记忆的限制。对这位患者的S记忆缺陷的性质进行了更全面的检查，这是在他最初测试之后发展起来的一系列范例。人们再次发现，尽管他完整的分析能力允许将材料保留在工作记忆中，但一旦超过工作能力，检索信息几乎是不可能的。患者显然无法区分S最近分析的线索和他的语义层次中与该线索最强的现有关联。对他的逆行记忆能力的分析表明，他几乎不能从过去回忆起任何公开或私人性质的真实情节。相反，他似乎依赖于他的语义记忆的概括来重建可能发生的事件。
A patient with amnesia due to encephalitis was previously described in 1976 as having normal short-term memory and an intact ability to perform semantic analysis. Despite this ability, his retention beyond the limits of short-term memory was nearly nil. The nature of this patient''s retrieval deficit was examined more completely using a series of paradigms developed subsequent to his initial testing. Once again it was discovered that while his intact analytic abilities allowed retention of material in working memory, as soon as that working capacity was exceeded, retrieval of information became nearly impossible. The patient apparently could not discriminate between a cue''s most recently analyzed associate and the strongest existing associate to that cue in his semantic hierarchy. An analysis of his retrograde memory ability showed that he could retrieve almost no real episodes of either a public or private nature from his past. Instead, he seemed to rely on generalizations from his semantic memory to reconstruct probable events.
