Temporal changes in the transfer of visuomotor adaptation for different distances away from the trained direction: temporal decay of visuomotor adaptation transfer to target locations local: within ±15° (A), intermediate: 30° and 45° (B), and distant: >60° (C) beyond the trained adaptation direction (n = 32). As in Fig. 2B, delay represents the average time before the movement was executed. The transfer local to the trained direction decayed across time and distance (2-way ANOVA, P < 0.001 for main effect of movement direction and P < 0.001 for main effect of delay). The time constant for transfer at 0° and 15° is 3.8 ± 5.2 s and 5.7 ± 13.7 s, respectively. Transfer to targets located at an intermediate distance showed a decay across the spatial separation but was constant across time (2-way ANOVA, P = 0.85 for main effect of delay). Generalization to distant targets was near constant across both time and space (2-way ANOVA, P = 0.2 for main effect of movement direction and P = 0.79 for main effect of delay).
