FIGURE 7.

Average adaptation for the velocity-dependent force-field (blue) and visuomotor rotation (green) task (Experiment 2b; n = 20, 10 female). (A) Average cursor paths from the velocity-dependent force field. Cursor paths were averaged across the baseline phase. The first and last three trials of the adaptation phase were averaged across participants. Similarly the first three trials of the washout phase were averaged across participants. Note that cursor and hand paths were the same in the velocity-dependent force field. (B) Average cursor paths from the visuomotor rotation. Cursor paths are presented in the same manner as panel (A). (C) Peak lateral and angular cursor deviations throughout the experiment. The line represents the group mean and the shaded regions represent the SEM. Individual differences in adaptation were measured in Early Adaptation, Late Adaptation, and Washout (shaded gray regions). The left y-axis corresponds to the velocity-dependent force-field task (peak lateral deviations) and the right y-axis to the visuomotor rotation task (cursor angle). (D) Amount of adaptation in Early Adaptation in the force field and rotation tasks. The angular deviations of the cursor in the visuomotor rotation task are plotted on the x-axis and peak lateral deviations for the velocity-dependent force task are plotted on the y-axis. The trendline was obtained via robust linear regression and is used for visualization purposes. Error bars represent the mean and SEM. (E) Average amount of adaptation in Late Adaptation. (F) Average peak lateral and angular cursor deviations in Washout. Data in panels (E,F) are presented in the same format as panel (D).
