Communication success and AAC: A model of symbol acquisition


This is a current project.


Many children with developmental delays, including autism, are at risk for not developing symbolic communication (words) so are often taught augmentative or alternative communication (AAC). This longitudinal study is testing the relationships between variables and three different outcomes – symbolic vocabulary development, communication success and symbol substitutions. Participants are 100 young children with developmental disabilities and 20 young children with autism spectrum disorders (ASD) who are learning AAC. This research is expected to produce the largest data set collected thus far from a prospective study of young children learning AAC.
