近年来，许多研究都探讨了内侧颞叶（MTL）的结构如何支持回忆和熟悉，这两个过程被广泛认为是支持识别记忆的过程。在神经成像和损伤研究中，用来分离回忆和熟悉的行为方法通常假设回忆是一个分类过程，而不是一个连续的过程。分类过程是一个特定测试项目发生或不发生的过程（当它发生时产生高置信度和高准确性），而连续过程是一个分程度的过程（产生不同程度的置信度和准确性）。研究表明，海马体选择性地支持回忆过程（例如那些使用记忆/知道过程或依赖于接受者操作特征分析的研究）通常依赖于回忆的分类观点，但最近的许多证据表明，回忆是一个连续的过程。如果回忆是一个连续的过程（也就是说，如果回忆是分程度的），那么海马体选择性地支持回忆的证据也与海马体同时支持回忆和熟悉的观点是一致的。我们建议可以使用另一种方法来有效地研究记忆和熟悉度，无论记忆是分类过程还是连续过程，都是有效的。
Many recent studies have investigated how the structures of the medial temporal lobe (MTL) support recollection and familiarity, which are two processes widely thought to support recognition memory. The behavioral methods that are used to isolate recollection and familiarity in neuroimaging and lesion studies typically assume that recollection is a categorical process and not a continuous process. A categorical process is one that either occurs or does not occur for a particular test item (yielding high confidence and high accuracy when it does occur), whereas a continuous process is one that comes in degrees (yielding varying degrees of confidence and accuracy). Studies suggesting that the hippocampus selectively supports the recollection process (such as those that use the Remember/Know procedure or rely on Receiver Operating Characteristic analysis) generally depend on the categorical view of recollection, but much recent evidence suggests that recollection is a continuous process. If recollection is a continuous process (i.e., if recollection comes in degrees), then evidence that has been taken to mean that the hippocampus selectively supports recollection is also compatible with the idea that the hippocampus supports both recollection and familiarity. We suggest that an alternative method can be used to effectively investigate recollection and familiarity in the MTL, one that is valid whether recollection is a categorical or a continuous process.
