"Remember where you last saw that card": children's production of external symbols as a memory aid.
Four experiments examined the age at which children start to use external symbols to aid their memory and how external symbol use affects both their memory performance and information allocation strategies. In Experiment 1, children in Grades 1, 3, 5, and 7 played a memory card game (Concentration) twice, once with the opportunity to make notes to aid performance and once without the opportunity. Grades I and 3 students tended to produce nonmnemonic notations, whereas Grades 5 and 7 students were more likely to produce functional, adultlike notations that aided performance in the task. In Experiments 2a and 2b, unexpected removal of children's notations led to a decrease in performance. suggesting that the spontaneously produced notations were being used as an external store rather than as an aid to encoding information. Experiment 3 examined whether all information was placed in external storage or if some types of information remained in memory. Grade 7 students who had their notations unexpectedly taken away were able to recognize the identity of the cards they had previously seen but had more difficulty remembering their locations. They appeared to place the location information mainly in external storage while retaining the identity information in memory. These results suggest that in mid-childhood, children begin to distribute information actively between internal and external memory storage.
