In four experiments with children aged 6-12 years and young adults, the developmental trajectories of two separate mechanisms underlying recognition memory - familiarity and recollection - were examined using event-related potentials (ERPs). Developmental changes were evident in both mechanisms of recognition memory. The data also revealed some surprising similarities across the life-span and emphasize the importance of strategic modulation of memory retrieval. Furthermore, the present investigation of memory development highlights age-related changes in cognitive processes and the maturation of the brain structures underlying these developmental changes.
