“…In contrast to the dynamic stability achieved with ball-racket impacts during the decelerating racket trajectory, hitting the ball with an accelerating trajectory produces unstable performance and errors amplify from one bounce to the next (Figure 2B,C). To compensate for such unstable performance, the novice participants can actively correct for errors by adjusting their racket trajectory to propel the ball either higher or lower than the previous bounce, based on visual information about the error (de Rugy, Wei, Müller, & Sternad, 2003; Wei et al, 2007; Siegler, Bazile, & Warren, 2013). However, with practice, participants learn to hit the ball with negative acceleration, reducing the necessity for active correction of errors (Wei et al, 2008).…”
