经典遗忘症涉及自由回忆中时间上遥远的项目的选择性记忆障碍（受损的首要性）以及近因项目的记忆相对保留。这种异常的序列位置曲线传统上被认为是不同记忆过程之间区别的证据，健忘症与选择性受损的长期记忆有关。然而，最近的帐户正常的串行位置曲线强调的重要性，排练过程中产生的首因效应，并建议一个单一的时间独特性机制可以占首因和近因效应时，排练被认为是。在这里，我们探讨的模式，战略排练的病人非常严重的健忘症。当考虑到患者的复述模式时，时间独特性模型可以解释失忆和无控制回忆中的序列位置曲线。结果被认为是一致的时间独特性模型的自由回忆，他们激励强调排练模式在理解健忘症缺陷的自由回忆。
Classical amnesia involves selective memory impairment for temporally distant items in free recall (impaired primacy) together with relative preservation of memory for recency items. This abnormal serial position curve is traditionally taken as evidence for a distinction between different memory processes, with amnesia being associated with selectively impaired long-term memory. However recent accounts of normal serial position curves have emphasized the importance of rehearsal processes in giving rise to primacy effects and have suggested that a single temporal distinctiveness mechanism can account for both primacy and recency effects when rehearsal is considered. Here we explore the pattern of strategic rehearsal in a patient with very severe amnesia. When the patient's rehearsal pattern is taken into account, a temporal distinctiveness model can account for the serial position curve in both amnesic and control free recall. The results are taken as consistent with temporal distinctiveness models of free recall, and they motivate an emphasis on rehearsal patterns in understanding amnesic deficits in free recall.
