Abstract
A simple procedure is described for investigating stimuli selected as targets during urination in the commode. Ten normal males preferred a floating target that could be tracked to a series of stationary targets. This technique was used to bring misdirected urinations in a severely retarded male under rapid stimulus control of a floating target in the commode. The float stimulus was also evaluated with 9 institutionalized, moderately retarded males. Rapid autoshaping of directed urination occurred without the use of verbal instructions or conventional toilet training. The technique can be applied in training children to control misdirected urinations in institutions for the retarded, in psychiatric wards with regressed populations and in certain male school dormitories.
