Recent attention has turned towards metacognitive processes involved in creativity. One factor known to influence metamemory judgments is accessibility—the amount of and ease with which related information comes to mind. The present research explored how subjective accessibility (sAccessibility) influences both participants’ metacognitive predictions of their creative performance as well as their actual creativity using an alternate uses task (AUT). Participants predicted how creative their ideas would be for AUT objects with low vs. high sAccessibility (as determined by a norming study), (...) prior to generating ideas. High sAccessibility led to higher metacognitive predictions of creativity, but less creative ideas compared to low sAccessibility objects. Additionally, the serial order effect was moderated by sAccessibility such that objects with high sAccessibility started off less creative. This research extends recent empirical and theoretical work on creative metacognition, demonstrating a disconnect in the effects of sAccessibility on metacognitive predictions vs. actual creativity.
