Planning is an everyday activity that is extended in timeand space, yet is frequently studied in the absence ofinteractivity. Successful planning relies on an array ofexecutive functions including self-control. Weinvestigated the effects of interactivity and self-controlon planning using a sequential-task paradigm. Half ofthe participants first completed a video-viewing taskrequiring self-control of visual attention, whereas theother half completed the same task without the self-control constraint. Next, and within each of thesegroups, half of the participants manipulated cards tocomplete their plan (high-interactivity condition); for theother half, plans were made with their hands down (low-interactivity condition). Planning performance wassignificantly better in the high- than in the low-interactivity conditions; however the self-controlmanipulation had no impact on planning performance.An exploration of individual differences revealed thatlong-term planning ability and non-planningimpulsiveness moderated the impact of interactivity onplanning. These findings suggest that interactivityaugments working memory resources and planningperformance, underscoring the importance of aninteractive perspective on planning research.
