Two experiments were conducted in this study of effects of full physical guidance (folding the subjects' hands) that was made contingent on a mechanically defined leg movement response. Two severely mentally impaired adolescents served as subjects. Experiment I compared the effects of baseline and contingent full physical guidance procedures upon the leg movement response. Experiment I I compared the effects of several procedures incorporating full physical guidance to ones which developed operant baselines of leg movement responses. The results Indicated that full physical guidance functioned as an evocative stimulus for Subject 1 and as mild reinforcement for Subject 2.
