Accurately remembering how and when one's own learning occurs is an important metacognitive skill that matures during the early school years. In two studies, the impact of a delay on this ability was examined. In Study 1, 30 children in two age groups (4-year-olds and 5-year-olds) participated in two-staged learning events and were interviewed immediately after each event about the facts they had learned in the events and about how they had acquired them. Children in both age groups learned the facts, but had significant difficulty reporting on their own learning. In Study 2, 79 children in the same age range participated in one staged learning event and were given similar interviews as in Study 1, either immediately after the event or after a 2- to 3-day delay. Five-year-olds were more accurate in their memories of learning in the delay condition than in the immediate condition, but 4-year-olds showed no performance differences as a function of delay. Findings are interpreted in light of developmental literature on episodic memory, source monitoring, and memory binding.
