Sign language and multisensory input training of children with communication and related developmental disorders.

This report deals with the preliminary findings of a research project on simultaneous communication and multisensory input in the treatment of six autistic and communication disordered children. The children, aged 5 to 12, were taught manually signed English and speech using a multisensory-intrusion approach. The hypothesis was that such a technique would serve to alleviate the children's difficulties in information processing, organization of experience, and affect. The dependent measures were behavioral ratings derived from both structured (teaching) and unstructured (free play) sessions. The results indicate that the children manifested a consistent acquisition of sign language, which in some cases transferred into verbal communication skills. Moreover, statistical analyses of some of the observed socioaffective behaviors (i.e., nonsolitary play, interaction with peers and adults, exploration, and detachment) revealed tendencies supportive of the hypothesis. The variability of the data preclude any categorical statement in relation to the hypothesis. However, the preliminary results strongly support the continuation of the study.
