While motor performance can modify perception (Witt & Proffitt, 2005; Witt, Linkenauger, Backdash, & Proffitt, 2008), the time course of this change remains unclear because previous experiments have assessed perception only after the experimental action has occurred. To address this issue, we had participants throw a ball into various sized holes and report, in a haptic (experiment 1) or verbal manner (experiment 2), how large the hole appeared to be. Participants gave this report under one of three conditions: 1) concurrent with their throw of the ball, using video recording of unseen fingers; 2) immediately after the throw, while the hole is still visible; and 3) immediately after the throw, while the hole is not visible. The results were divided into successful and unsuccessful trials. Perception was altered only in Condition 3 for both experiments, indicating that the effect of performance on perception occurs only after the act of throwing, in a style similar to memory.
