Recognition memory: Adding a response deadline eliminates recollection but spares familiarity

Preserved hippocampal novelty responses following anterior temporal-lobe resection that impairs familiarity but spares recollection.

Although it is well established that the integrity of the medial temporal lobe (MTL) is critical for declarative memory, the functional organization of the MTL remains a matter of intense debate. One issue that has received little consideration so far is whether the hippocampus can function normally in the presence of a lesion to perirhinal cortex that produces noticeable memory impairments. Th...

Fornix microstructure correlates with recollection but not familiarity memory.

The fornix is the main tract between the medial temporal lobe (MTL) and medial diencephalon, both of which are critical for episodic memory. The precise involvement of the fornix in memory, however, has been difficult to ascertain since damage to this tract in human amnesics is invariably accompanied by atrophy to surrounding structures. We used diffusion-weighted imaging to investigate whether...

Recollection and familiarity in recognition memory: Evidence from ROC curves

Assessing the dissociability of recollection and familiarity in recognition memory.

Recognition memory is often modeled as constituting 2 separate processes, recollection and familiarity, rather than as constituting a single process mediated by a generic latent strength. One way of stating evidence for the more complex 2-process model is to show dissociations with select manipulations, in which one manipulation affects recollection more than the second and the second affects f...

Novelty effects on recollection and familiarity in recognition memory.

Recognition memory is better for novel or distinctive items than for non-novel items. However, it is not known whether these effects reflect changes in recollection or in familiarity-based recognition judgments. Some previous results have indicated that recollection should be more sensitive to novelty than to familiarity, whereas other results have suggested the opposite. We used avon Restorff ...
