再认记忆的双加工模型由Alberby（1991;也可参见Mandler，1980）提出，它假设再认记忆存在两个独立的组成部分：有意识的提取过程（回忆）和自动成分（熟悉）。老年人的记忆力似乎受损，但在熟悉度方面的研究结果好坏参半。使用神经病患者对这些成分的大脑基础进行的研究也没有定论。我们研究了回忆和熟悉，使用过程分离程序，在老年人的基础上，他们的额叶和内侧颞叶功能的特点。研究结果表明，只有一些老年人，这取决于他们的神经心理状态，是受损的回忆和/或熟悉：回忆似乎涉及额叶和内侧颞叶的功能，而熟悉似乎只依赖于功能与内侧颞叶。
The dual-process model of recognition memory proposed by Jacoby (1991; see also Mandler, 1980) postulates the existence of two independent components of recognition memory: a conscious retrieval process (recollection) and an automatic component (familiarity). Older adults appear to be impaired in recollection, but findings with respect to familiarity have been mixed. Studies of the brain bases of these components, using neurological patients, have also been inconclusive. We examined recollection and familiarity, using the process dissociation procedure, in older adults characterized on the basis of both their frontal and their medial temporal lobe function. Findings suggest that only some older adults, depending on their neuropsychological status, are impaired in recollection and/or familiarity: Recollection seems to involve both frontal and medial temporal lobe function, whereas familiarity appears to be dependent only on function associated with the medial temporal lobes.
