ABSTRACT
It has been suggested that it is important to be able to anticipate ball trajectories in racket sports such as tennis (Féry and Crognier, 2001), squash (Abernethy, 1990a), and badminton (Abemethy and Russell, 1987). Experts have consistently been shown to possess a significant advantage over less skilled players in utilising advance visual cues (e.g. racket and arm), thought to enable superior performance in anticipating ball trajectories (Abernethy, et al., 2001; Buckolz, et al., 1988; Williams, et al., 2002). The large set of published work suggesting an expert advantage have utilised a range of experimental methodologies with the majority having been conducted within artificial environments. This typically involves participants watching a video recording of a performance taken from the perspective of a performer. This visual representation is then either stopped at set times prior to and after the ball (or shuttlecock) is hit (temporal occlusion) or sections of the display are hidden from view (spatial occlusion).
