Strategies employed by children in tasks requiring prospective memory (i.e., remembering to do something in the future) were investigated to illuminate the nature of the processes involved, and their developmental and contextual determinants. Efficient strategy use was expected to increase with age but to decrease in an unfamiliar setting or on a task associated with higher sex-role expectations. Children were instructed to perform future activities after waiting 30 min. Children's clock-checking during the waiting period was assessed in their own homes or a university psychophysics laboratory. As predicted, strategic time-monitoring occurred less frequently in the laboratory than in the home. The anticipated differences associated with higher sex-role expectations and age were most salient for older boys in the laboratory setting. The findings indicate that, when observed in a familiar setting, children can be shown to employ sophisticated cognitive strategies. Emphasis is placed on the scientific power of the laboratory as a contrasting context for illuminating developmental processes.
