The Role of Remembering in Planning Dependent Sequences of Action

The purpose of this study was to consider the role of remembering in the development of the ability to plan and carry out sequences of dependent actions. A task calling for sequencing of choices was administered to 46 four-year-olds, 30 seven-year-olds, and 30 10-year-olds. Each child participated in both a remembering (control) condition and a facilitation-of-remembering condition. Performance was better in the facilitation-of-remembering condition than in the remembering (control) condition, but only for four-year-olds (p < .01), indicating that the failure to remember alternatives, rather than a lack of other cognitive abilities, may be a major obstacle in preschoolers' development of planning abilities. An apparent regression in performance of seven-year-olds (p < .01) is interpreted as an inappropriate application of transitional operative understanding of dependent events to situations involving only chance sequences.
