Precursors of mnemonic strategies in very young children's memory.
In 4 studies with 18-24-month-old children, evidence was obtained of strategy-like behaviors in a memory-for-location task in which the child had to remember in what natural location a toy had been hidden. The children exhibited behaviors that resemble the mature strategies of rehearsal and monitoring, including talking about the toy or its hiding place and looking or pointing at it during the delay interval. In Experiments 1 and 2, these strategy-like behaviors were engaged in differentially as a function of familiarity, both of the setting in which the task was embedded and of the task itself. Significantly more target behaviors occurred in an unfamiliar than in a familiar setting, and more target behaviors occurred on the first than on the second day of observation. In Experiment 3, when the basic memory task was modified to remove the memory demands from the child, very few of the strategy-like behaviors occurred, indicating that they were indeed memory specific. In the fourth experiment, the rehearsal-like behaviors were shown to be related to subsequent retrieval. We interpret these results as evidence of an early natural propensity to keep alive what must be remembered, a rudimentary and imperfect version of what will later become more elaborate and planful mnemonic strategies.
