Extending the race model frame work for eye-hand coordination. A: representative trials for 3 different observed behavioral responses. The central fixation spot, initial target (green), and final target (yellow) are shown, along with the eye (red) and hand (blue) trajectories. In an EH-initial trial (top), both eye and hand are directed to the initial target. In an EH-dissociated trial (middle), the eye is directed to the initial target while the hand is directed to the final target. In an EH-final trial (bottom), both eye and hand are directed to the final target. B: the frequency with which the 3 different trial types (EH-initial, black; EH-dissociated, dark brown; EH-final, light brown) occur in the observed data across population is shown separately for each subject.
