最近的一个案例研究记录了一位女性在没有使用记忆术的情况下准确回忆大量自传信息的能力，这些信息跨越了她一生的大部分时间。目前的研究报告基于11名表达相同记忆能力的参与者的发现，现在被称为高度上级自传体记忆（HSAM）。参与者被确定，并随后根据筛选公共事件的记忆特征。然后对他们进行个人自传体记忆测试，以及通过实验室记忆测试评估的记忆。此外，还进行了全脑结构MRI扫描。结果表明，HSAM参与者在回忆公共和个人自传事件以及这些事件发生的日期和日期方面表现得更好。然而，在大多数标准的实验室记忆测试中，他们的表现与年龄和性别匹配的对照组相当。神经解剖学的结果确定了9个结构的形态不同，从控制参与者。HSAM的研究可能会为自传体记忆的神经生物学提供新的见解。
A single case study recently documented one woman’s ability to recall accurately vast amounts of autobiographical information, spanning most of her lifetime, without the use of practiced mnemonics. The current study reports findings based on eleven participants expressing this same memory ability, now referred to as Highly Superior Autobiographical Memory (HSAM). Participants were identified and subsequently characterized based on screening for memory of public events. They were then tested for personal autobiographical memories as well as for memory assessed by laboratory memory tests. Additionally, whole-brain structural MRI scans were obtained. Results indicated that HSAM participants performed significantly better at recalling public as well as personal autobiographical events as well as the days and dates on which these events occurred. However, their performance was comparable to age- and sex-matched controls on most standard laboratory memory tests. Neuroanatomical results identified nine structures as being morphologically different from those of control participants. The study of HSAM may provide new insights into the neurobiology of autobiographical memory.
