Treatment of assaultive hair pulling in a multihandicapped youth.

The course of treatment for hair pulling in a moderately retarded, visually impaired 9-year-old male is described along with the effectiveness of an ammonia inhalation procedure to eliminate this behavior. However, before discovering this successful procedure, other well-known techniques such as DRO, TO, overcorrection, and shaping all failed. Since rapid treatment effectiveness could be assumed to be the norm, given the operant literature, the extensive course of treatment reported here serves to document that perseverance may also be a necessary component of successful behavior management strategies.
