Figure Lengend Snippet: A Representative hand paths from subject 1 from all three experimental sequences are shown. The last two trials from the pre-exposure sequence are shown in gray (dashed lines), underlying all other trials. The first trials from the mass-exposure session (mass-perturbed, left column), the last two trials from the same session (mass-adapted, center column), and the first two trials from the post-exposure session (aftereffects, right column) are displayed. Dominant paths are shown above, whereas nondominant hand paths are shown below. B Mean performance measures, hand-path linearity and final position error, are averaged across all subjects and shown for individual cycles of movement. Baseline performance, measured for each subject as the average of the last eight cycles from the pre-exposure sequence, has been subtracted from each value prior to computing the average across subjects. Thus, the performance measures shown represent a change from baseline performance, and can be either positive or negative. Each cycle represents the average of a single movement to each of eight targets across all subjects (mean ± SE). The time course of each experimental sequence, pre-exposure, mass-exposure, and post-exposure, is shown. Vertically oriented gray bars mark the cycles for which the trials in Fig. 2A were extracted. Data have been fit to exponential functions, using the “CurveFit” function in Igor Pro (Wavemetrics)
