Annotation	Perceptual-motor adaptability of older adults (age 65+) was assessed. Participants in two groups (younger, age 20-36; and older, age 67-87) pointed 100 times at a straight-ahead visual target while looking through laterally displacing prisms, with the hand visible early in the pointing movement. After-effect tests were administered after adaptation. Each group was then split into decay and re-adaptation subgroups in which respective treatments were given twice. After each treatment, after-effect tests were re-administered. Eye-hand total shift was significantly smaller for older participants, and visual shift did not appear. Re-adaptation produced greater reduction in after-effects than did decay; this effect was the same for both groups. The main conclusion is that perceptual-motor adaptability declines with advancing age. (RH).
