Research Tuesday: Comparing Picture Exchange and SGDs

Picture exchange is powerful strategy for building symbolic communication in individuals with significant communication difficulties. We’ve posted about implementation of PECS a few times, and included references to research supporting its efficacy in some additional posts. Today, we look at a sequence of three single subject design experimental studies by Dr. Jeff Sigafoos and other researchers that looked at how the use of picture exchange and AAC devices (SGD condition) impacted social interaction. In the initial study, the team taught requesting skills either with picture exchange or AAC devices and then looked to see if there were any changes in social interaction. They hypothesized that the physical act of picking up a symbol and giving it to someone, as with the picture exchange condition, would make the learner less likely to turn away from his communication partner.
