The Ontogeny of Long‐Term Retention During the Second Year of Life

The Ontogeny of Long‐Term Retention During the Second Year of Life 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Developmental Science Wiley

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.
