Abstract
Preschool children can use external symbols to aid their executive functioning (EF). The purpose of the current study was to investigate how symbols boost EF, specifically investigating the role of psychological distancing and symbolic understanding. Preschoolers were assessed on their level of symbolic understanding and completed two EF tasks. Half the children completed the first EF task using symbols, and all children completed the second EF task without the aid of symbols. Results indicated that children in the symbol group at first did significantly worse while they were using the symbols compared to the control group, though their performance improved over time. Control group performance was significantly worse in the second EF task. Symbolic understanding was sometimes related to EF performance for children in the symbol group but not the control group. The current research highlights the complexity of symbol use to influence cognitive functioning.
