Students with severe disabiliites often experience great difficulty in meeting their communicative needs. Recently, researchers have developed augmentative and alternative communication(AAC) as effective means for those with communication problems.

Subjects were 4 nonverbal students with severe disabilities who attended in special elementary school. Simple grocery shopping was used for functional AAC training context. Parallel design was used and generalization maintenance effect was examined. The results of this study showed: (1) all 4 subjects acquired the proper communicative behavior through functional AAC training, (2) acquired communicative behaviors were generalized at other two stores, (3) acquired communicative behaviors were maintained 3 weeks after training, (4) There were no difference in communicative behaviors between the subjects using communication board and VOCA.
