Schematic of Apparatus and Task
Note. (a) The kinematics of planar reaching movements were measured using a digital camera that detected the location of a colored marking on an individual’s hand and displayed that location to the participant in real time (red cursor on the computer screen). (b) The mapping showing which symbol was associated with each target for Experiment 1. The symbols are displayed at the target location only for visualization purposes, they appeared at the center of the screen over the start position during the experiment. (c) Trials consisted of either no precuing, direct precuing, or symbolic precuing. Horizonal bars indicate times in the trial during which the symbol or the target were displayed. Musical notes indicate times in the trial during which auditory tones were presented.
