Teaching autistic children to use sign language: some research issues.

摘要: Three questions are raised with respect to the use of sign language as an alternative system communication for nonverbal autistic children. First, does teaching a child facilitate speech development? The data suggest that following simultaneous training, mute children not likely learn talk; however, combination training and separate vocal may have synergetic effect on development. In contrast, who initially good verbal imitation skills apparently show gains in alone. Second, what is upper limit acquisition? Data abstract concepts, syntax, generative can be taught. Procedures used operant conditioning prove useful complex signing skills. Third, acquisition result general improvement adaptive functioning? It appears some do increases spontaneous communication, decreases self-stimulatory behavior, social However, these outcomes often difficult interpret. Some described help clarify relationship between behavioral improvement.
