Children with Autism Spectrum Disorder (ASD) exhibit difficulties with both verbal and nonverbal language with approximately 50% of children diagnosed with autism remaining functionally mute into adulthood (Charlop & Haymes, 1994; Charlop-Christy, Carpenter, Le, LeBlanc, & Kellet, 2002). This study explored intervention using the Picture Exchange Communication System (PECS) for two nonverbal preschoolers with ASD. The effects of PECS using two picture systems, Picture and Words (P&W) and MorphoPhonic (MPh) picture word, was assessed in the communicative outcomes after 6 weeks of intervention. This study asked if MPh picture words would elicit more picture-exchange communication acts in functional contexts than P&W and if MPh picture words would elicit a greater number of verbal communications than pictures accompanied by words. The results suggest that changes in communication can be observed in 6 weeks of intervention. Specifically greater gains were observed in the MPh picture word condition over the P&W condition.
