Augmented communication was used to reduce aberrant behaviors in a 19-year-old student with severe mental retardation and behavior disorder.

All inappropriate targeted behaviors showed a marked decrease. Concomitant behaviors included increased language, reduction of tantrums, and positive affect. (Contains 19 references.) (Author/JDD)
