Visual-Propriocetive Correspondence in the Para-Median Plane

2 experiments in which Ss matched a proprioceptively perceived stylus to a visual target in the para-median plane show that Ss make idiosyncratic errors which are stable over periods of at least several days. A technique for comparing visual and proprioceptive spaces is used to Show how matching errors vary within the para-median plane. These errors are interpreted as the result of inadequate inter-calibration of visual and proprioceptive space perception, and their implications for movement control are discussed.
