The ontogeny of long-term retention during the second year of life

Journal Article


Abstract


  • Developmental changes in retention were assessed in two experiments with 18-and 24-month-old infants. In both experiments, infants were tested in a deferred imitation paradigm. In Experiment 1, independent groups of infants were tested either immediately or after delays of 1, 14, 28 or 56 days. There was no age-related difference in the spontaneous production of target actions (baseline) or in immediate imitation. There were age-related changes in retention after longer delays. Eighteen-month-olds exhibited retention for 14 days and 24-month-olds exhibited retention for at least 56 days. In Experiment 2, the maximum duration of retention by 24-month-olds was assessed. Independent groups of infants were tested after 3 or 6 months. Infants exhibited some evidence of retention after 3 months; however, forgetting was complete after 6 months.
