Percentage direct responses are re-plotted by hand pointing direction in the hand-to-hand (top panel) and arrow-to-hand (bottom panel) tasks, separately for left and right test hands.

<p>These plots illustrate an asymmetry in baseline (blue) performance such that participants are more accurate in judging the pointing direction of leftward pointing right hands and rightward pointing left hands when the task is most difficult. Error bars show +/1 S.E.M.
