Award Description: The purpose of this project is to investigate the relative contribution of familiarity and recollection to the development of visual recognition memory in infants. Recollection involves the retrieval of information about the context in which an item was previously encountered, and is thought to depend critically on the hippocampus. Familiarity, on the other hand, involves the assessment of global similarities between study and test items that appears to be mediated by perirhinal cortex and high-level visual association areas. The extent to which recollection and familiarity contribute to visueal recognition memory in infants is unknown, and is critical to our understanding ob both memory development and brain development in infants. Our hypotheses is that familiarity contributes to infant recognition earlier in development than recollection. Moreover, given that relatively protracted course of development of the hippocampus, the dentate gyrus in particular, we hypothesize that recollection does not emerge until sometime during the second year of life. To test these hypotheses, we will examine the effects of manipulations known to disslocate recollection and familiarity in adults and experimental animals on infants' performance in the visual-paired comparison (VPC). The specific aims of this award are to: (1) Examine the contribution of recollection to infant visual memory and (2) Examine the contribution of familiarity to infant visual recognition memory. This project is the first step in a long-term plan to systematically examine the neural mechanisms of recollection and familiarity in infants.
