Figure 4

Time series of racket (black) and ball (gray) trajectories illustrating the dependent measures. A bounce is the event between two consecutive ball-racket impacts. Error was defined as the unsigned difference between the target height and the maximum ball amplitude at each bounce. Racket acceleration at impact was defined as the racket acceleration 25 ms before the ball-racket impact of each bounce. Ball velocity at release was defined as the velocity of ball at the instantaneous ball-racket impact of each bounce. Bounces, where the difference between the ball and racket maximum positions was below 0.25 m, referred to as stuck bounces, were excluded from the data analysis in Experiments 2 and 3.
