Figure 2.

Three-way interaction of (a) spatial reversal point variability (σ_spatial) and (b) movement duration, presented for all experimental conditions. Flexed, neutral, and extended wrist postures are represented by dark, intermediate, and bright gray bars. Flexion and extension σ_spatial or movement duration are indicated by solid and hatched bars, respectively. Asterisks indicate significant differences between both sides within a condition (P < 0.05). Error bars represent standard error. Informational timing and neuromuscular mediators are indicated as in Table 1
