An attempt was made in this study to eliminate the body rocking behavior of a twenty-three-year-old totally blind male, individual, presently classified as moderately retarded. Consequences were placed upon, rocking behavior in seven experimental phases, employing time-out from a positively reinforcing stimulus as a punisher. More specifically, apparatus were designed in such a manner that rocking would result in elimination of the auditory and visual portion of a television, and in a later phase, the auditory portion of a transistor radio.
