This paper reports a case study of an 8-year-old deaf, blind, and mentally impaired girl who was self-abusive. The behavior was excessive to the point that she sustained fractures to her jaw and arm and had to be restrained. Several treatment techniques were unsuccessfully attempted, including sensory stimulation, aversive conditioning, and extinction. Subsequently, a sensory affective training approach was used, with a staff member holding the girl throughout the school day, massaging her, rocking her, developing a trusting relationship. The intervention was successful, with hitting behaviors dropping from 400 times per hour to an average of two times per day. The girl became more autonomous and interested in her environment and later learned to sign and to take care of her basic needs. (JDD)
