Fig. 1.

A: the 4 aiming conditions. The cursor is depicted with a black circle, and the limb was not visible. The dotted white circle is a placeholder for the other start position. The aligned conditions are depicted in the top left and bottom right corners in which the starting cursor and starting finger position were in the same location (i.e., F1C1 and F2C2). The misaligned conditions are depicted in the bottom left and top right corners (i.e., F1C2 and F2C1), in which the starting finger position was displaced from the starting cursor position which represented their finger. Note that participants did not have cursor feedback during the movement. B: experimental setup. When the participant’s arm was underneath the half-silvered mirror setup, the participant did not have vision of the limb. The black square underneath the participants arm was Velcro and allowed for a custom positioning of the elbow rest. The 2 cursor starting positions and the target positions are displayed. Note that only 1 cursor starting position was displayed for each trial.
