Point-light studies have shown that the minimal visual information required to anticipate an opponent’s action is kinematics. Little is known of whether point-light displays can be used to improve anticipatory skill and whether benefits can be found on video simulation and in-situ tests. The purpose of this experiment was twofold: (i) to examine the efficacy of point-light display training to video simulation and in-situ anticipation tests and (ii) to compare point-light display training to sports-specific practice (control). Cricket batting was used as an exemplar striking sport skill. Cricket batsmen from two different cricket clubs were recruited and assigned in a quasi-random fashion to a point-light display training group (n = 6) and a control group (n = 6). A pre- and post-test control group design was used where participants were assessed using previously validated video simulation and in-situ cricket batting tests. Point-light displays of a cricket bowler delivering three different ball types were developed with temporal exaggeration applied between key kinematic events previously reported in the literature to provide anticipatory information. Displays were presented under three levels of temporal occlusion including occlusion at the point of ball release and prior to ball bounce, with a no occlusion control condition. Participants were required to indicate their prediction of ball type in an answer booklet, with feedback provided for occluded trials. The point-light training group received 6 weeks of anticipatory training including one session per week of 36 trials. In the video simulation test, results revealed improvement for prediction of ball type for the point-light training group, but not the control group. In the in-situ test, again, results revealed improvement only for the point-light training group for body positioning (foot movements), but not for bat-ball interception. The findings can be explained through the common-coding and neural visual pathways theoretical frameworks. Practical application of the findings will also be discussed.
