Fig. 4.

Effect of catch trials on movement endpoints. Vertical (A and C) and horizontal (B and D) coordinates of the endpoints during precatch and catch trials are shown for the 45-degree target (black), the 135-degree target (gray), and nonredundant control target (white). The target orientation has a stronger effect on the horizontal component, with endpoints shifted toward the right for the 45-degree target and to the left for the 135-degree target. During catch trials, the endpoints for the oriented targets shifted to the left for reaching with the right hand (B), although the shift was stronger for the 135-degree target. For reaching with the left hand (D), the shift was more strongly rightward, and the interaction was again significant.
