Empirical averaged coordination pattern alignment and magnitude. A: normalized, smoothed coordination pattern alignment after been averaged across all trials separated by task difficulty, i.e., smooth-small (dashed) and rough-large. The threshold of the transition onset is marked with a horizontal line at 0.8, the coordination pattern for the smooth-small case starts the transition sooner than the coordination pattern for a rough-large case (−330 vs. −210 ms, respectively). The thinner dashed lines represent the coordination pattern alignment plus or minus their standard errors for each condition. B: normalized, smoothed coordination pattern magnitude after having been averaged across all trials separated by task difficulty i.e., smooth-small (dashed) and rough-large. The threshold of the transition onset is marked with a dashed horizontal line at 0.2, the coordination pattern for smooth-small case starts the transition slightly sooner than the coordination pattern for a rough-large case.
