A study examined the use of sensory integration techniques to reduce the maladaptive behaviors that interfered with the learning of nine high school students with mental impairments attending a special school. Maladaptive behaviors identified included rocking, toe walking, echolalia, resistance to change, compulsive behaviors, aggression, tantrums, monotone speech, and gagging. A literature review examined the relationship between the senses and behavior of those with disabilities; the functions of nervous system and sensory integrative processes; and various methods of behavioral intervention including aversives, drugs, megavitamins, diets, psychotherapy, animal therapy, auditory integration therapy, and sensory integration techniques. The intervention involved the use of various sensory integration techniques including auditory/vestibular, visual, olfactory, gustatory, tactility, speech/communication, behavior, and balance techniques. After the intervention, the teacher reported a decrease in maladaptive behaviors and increase in student enjoyment of the activities. Appendices include observation checklists, a caretaker questionnaire, and the parental consent form. (Contains 28 references.) (CR)
