Figure 10.

Results for the motion discrimination task comparing device on (blue) versus device off (red) versus a scrambled condition (magenta). (A) Success rate at 7°/s. (B) Success rate at 15°/s. (C) Success rate at 30°/s. Chance level (25%) is shown as a dotted horizontal line. Circles show the average of 24 trials at each time point, shaded progressively darker for later dates and labelled with week number. The height of the bar is each subject's average across all time points. Statistical significance of within-subject comparisons is shown; *** P < 0.001; ** P < 0.01; NS = not significant. Friedman tests for S3 at 7°/s were significant, but post hoc comparisons were not; hence, significance is not indicated for these data.
