Schlosser, R. W.; Wendt, O.: Effects of Augmentative and Alternative Communication Intervention on Speech Production in Children With Autism: A Systematic Review. I: American Journal of Speech-Language Pathology , 2008(17), s. 212-230.Language: Engelsk

Summary: This systematic review aimed to determine the effects of augmentative and alternative communication (AAC) intervention on speech production in children with autism or pervasive developmental disorder - not otherwise specified. Results: Nine single-subject experimental design (27 participants) and 2 group studies (98 participants) were included. Results indicated that AAC interventions do not impede speech production. In fact, most studies reported an increase in speech production. However, in-depth analyses revealed that the gains were rather modest. Conclusions: The modest gains observed require realistic expectations among clinicians and other stakeholders.
