Abstract
An individual may fail to recall an item from memory but still feel that it would be recognized on a later test, a retrieval state termed
the "feeling-of-knowing" (FOK). In this study we used event-related fMRI and the FOK to examine both encoding- and retrieval-related
factors that are associated with different levels of recall performance: successful retrieval of a previously studied item, retrieval failure
accompanied by the FOK, and retrieval failure without any FOK. The results revealed one predominant pattern of retrieval-related
activation: an intermediate level of activation for FOK--less than that associated with successful recall and greater than that associated with
unsuccessful recall (frontal and left parietal cortices). Two further patterns were also observed: greater activation for both successful recall
