Conflict Inhibitory Control Facilitates Pretense Quality in Young Preschoolers.

The present research explores the role of inhibitory control in young preschoolers' pretense ability using an ego depletion paradigm. In Experiment 1 (N = 56), children's pretense ability was assessed either before or after participating in conflict inhibitory control or control tasks, and in Experiment 2 (N = 36), pretense ability was measured after children engaged in either conflict or delay inhibitory control tasks. In both experiments, pretense scores were significantly higher only after engaging in conflict inhibitory control tasks. Further, pretense scores were positively correlated with inhibitory control scores when conflict inhibitory control was not experienced first. This pattern of results suggests that inhibitory control may underlie pretense, and conflict inhibitory control can boost the quality of children's subsequent pretending.
