| Abstract: |
This study examined the effects of mother-implemented Picture Exchange Communication System (PECS) training on the independent communication of three young children with autism spectrum disorders. Three mothers were trained to teach their child PECS Phases 1 through 3B, which they did with high integrity. Moreover, all three children successfully acquired independent picture exchanges that were generalized to a different communication partner and maintained for at least 1 month. Vocalizations across participants showed limited or no improvement. These findings systematically extend previous PECS research by training mothers to be the primary implementers of PECS training. In addition, this research provides practitioners with insight into the feasibility and necessity of parent-implemented PECS training. |
