Automated reinforcement of head posture in two cerebral palsied retarded children
Journal/Book: Percept Mot Skills. 1975; 40: 619-22.
Abstract: A transistor radio activated by a mercury switch was used to reinforce head posture in two retarded children with severe cerebral palsy. Under the contingent music condition dropping the head forward automatically terminated the broadcast (music). A comparison of baseline and treatment phases showed that head orientation was strongly controlled by contingent music.
