Figure 1. . Illustration of computer-based cognitive-motor integration task.

The green circle denotes the central home target in which all movements begin. A red target appears in one of four peripheral directions (90° to top, bottom, left or right of center) after 4000 ms which serves as the ‘Go’ cue. (A) The standard condition, in which eye and arm movements are congruent (moved to the same peripheral target). (B) The non-standard condition, in which vision and movement are decoupled due to a plane dissociation (eyes look at vertical screen while hand moves along horizontal screen), and visual feedback reversal (cursor movement 180° rotated from hand motion).
