Behavioral results.

<p>The behavioral results showed a significant linear increase of tapping speed consistent with the experimental manipulation for all participants. The actual tapping speed of the right index finger from all individuals (S01-05, mean ± individual SE), as well as the average (AVG) is plotted dependent on the required speed in panel <b>A</b>. Second, there was a significant linear increase of error rate with increasing demand on bimanual coordination (from left to right) in all participants. In panel <b>B</b> the individual error rate (S01-05, mean ± individual SE), and average (AVG) is plotted for the four performed tapping sequences.
