Figure 2.

Behavioral results: kinematic control experiment. Movement parameters (A–D) during reaching-to-point (no lining) and reaching-to-grasp (bold lining) trials and the end-point variability (E) during reaching-to-grasp trials toward the small (light gray) and large (dark gray) objects are shown. A–D, The histograms illustrate the group means (±SEM) as a function of movement type and object size for the following movement parameters: A, RT; B, MT; C, HPV; D, HT. E, Histogram illustrates the group mean (±SEM) as a function of object size of the three-dimensional 95% confidence intervals of the end-point position of the thumb, index finger, and middle finger.
