The aim of this study was to investigate the contribution of stereo vision to the acquisition of a natural interception task. Poor catchers with good (N = 8; Stereo+) and weak (N = 6; Stereo¡) stereo vision participated in an intensive training program spread over 2 weeks, during which they caught over 1,400 tennis balls in a pre-postretention design. While the Stereo+ group improved from a catching percentage of 18% to 59%, catchers in the Stereo¡ group did not signiWcantly improve (from 10 to 31%), this progress being indiVerent from a control group (N = 9) that did not practice at all. These results indicate that the development and use of of compensatory cues for depth perception in people with weak stereopsis is insuYcient to successfully deal with interceptions under high temporal constraints, and that this disadvantage cannot be fully attenuated by speciWc and intensive training.
