Young children's verbal recall for personally experienced events was examined over extended time periods across the traditional boundary of childhood amnesia. Forty children, aged 5½, discussed with an experimenter personal experiences that had taken place when they were as young as 1½. At 5½ children had not yet forgotten at least some events from before age 3½, the average offset of childhood amnesia. There was a qualitative shift in children's recall for events that occurred before age 2; for events that happened before age 2, only around half of children's recall was accurate. For events that occurred after this age, over 75% of children's recall was accurate. Complete forgetting of very early childhood has not yet occurred by age 5½.
