  • Descrição: The aim of the present study was to help resolve conflicting findings and interpretations regarding the visual control of basketball shooting by examining the looking behavior of 6 expert basketball players (3 with a low shooting style and 3 with a high shooting style) executing both free throws and jump shots. Based on previous findings, they hypothesized that low-style shooters would look at the target relatively long before their hands and ball occlude the target in the free throw but for a shorter duration in the jump shot. In addition, the authors hypothesized that high-style shooters would look at the target during the final elbow extension both in the free throw and the jump shot. With the more dynamic shot task (i.e., the jump shot), the authors found that low-style shooters looked at the target only half as long (1 vs. 0.5 s) as in the free shot without any consequence for their shooting performance. This finding is consistent with previous evidence for the informative value of the last moments before moment of line of sight (mLoS) (de Oliveira et al., 2006) as well as with the finding that viewing the target for 3 s prior to movement initiation was insufficient for accurate performance if no vision was allowed during the movement (de Oliveira et al., 2007). In this context, the argument that low-style shooters must preprogram their movements due to the target occlusion following mLoS is invalid. Because the duration of mLoS is shorter than the visual motor delays reported in the literature, low-style shooters may have used updated optical information at the moment of ball release. Again as hypothesized, high-style shooters looked at the target during the final shooting movements. This hypothesis was based on previous occlusion studies in which a visible target after mLoS was sufficient and necessary for accurate jump shooting using a high style (de Oliveira et al., 2006; Oudejans et al., 2002). The present results extend this previous finding by demonstrating that players actually gaze at the target while airborne, and that the pattern of looking behavior is similar to that in the free throw.
