title: The growth of memory during infancy.
abstract: Eight middle class infants were administered a series of tasks over a nine month period from 5 to 14 months of age. Major procedures included object permanence, vacillation, memory for locations and pictures, and reaction to unfamiliar adults and to separation. The results suggested that during the last half of the first year there is a major enhancement in the ability to retrieve a representation of a past event, to compare that representation with present experience, and to tolerate both longer delays between an original and transformed event and greater interference during those delays. It was suggested that many of the diverse phenomena that appear during the last half of the first year are mediated, in part, by an amplification of memorial capacity.
