Anticipating the movement of football (soccer) goalkeepers.

The outcome of a penalty kick can pivot the fate of a football match. While previous research has mainly examined how goalkeepers anticipate shot direction, little is known about how penalty takers anticipate goalkeeper movements when using a keeper-dependent strategy. The current study examined how temporal constraints shape the penalty takers' ability to anticipate the movement direction of the keeper, and whether expertise plays a role in such anticipation. Participants (N = 253; 130 experts; 123 novices) completed a temporal occlusion task in which they viewed 64 penalty kicks filmed from the taker's perspective. On each trial, participants indicated whether the goalkeeper would dive left or right. Videos began 4 s before simulated foot-ball contact and were occluded at four time points (0, 200, 400, 600 ms before contact). Overall accuracy decreased as occlusion occurred earlier, from 95% at 0 ms to 51.9% at 600 ms. Performance was reliably above chance at 0 ms, 200ms, and 400ms, but not at 600 ms, indicating that penalty takers could anticipate goalkeeper movement direction before foot-ball contact, but not at the earliest occlusion time. Furthermore, experts outperformed novices across occlusion times. Additional analyses showed that this effect was more closely related to years of football experience than to frequency of football watching. Together, these findings quantify perceptual constraints on anticipating goalkeeper movements and suggest that passive and active forms of experience contribute differently to anticipatory performance.
