Fig. 8.

Extended visuomotor rotation learning experiment 8, with both arms experiencing switching visuomotor perturbations and switching bimanual movement contexts Δ180°/Δ0°. The 1st and last 2 batches were in the null condition (N). A: raw trajectories for both arms, plotted as in Fig. 6. Trajectories for 1st 4 trials for each subject (thin gray line) and mean across all 6 subjects (thick black line) are shown for the left and right arms for contexts Δ180 and Δ0°. The 1st column shows the trajectories during pre-exposure (batches 1 and 2), the 2nd column during initial exposure (batches 3 and 4), and the 3rd column during final exposure (batches 69 and 70). B: signed mean SAE (solid line) and SE (shading) over all 6 subjects for the left arm. C: signed mean SAE for the right arm, plotted as in B.
