Systematic laboratory studies of retention-retention beyond a few hours or a few days-of skill in performing complex perceptual motor tasks are in short supply. In contrast there is no shortage of anecdotal accounts of phenomenal proficiency in typing, ice skating, bicycle riding, and the like, displayed after years (and years) without practice. Largely as a consequence of anecdotes, many erudite persons (with some psychologists in the forefront among them) firmly believe that all motor skills are retained indefinitely while verbal and other symbolic materials are soon forgotten.
