The present study was designed to extend the literature by replicating the choice making protocol described by Sigafoos et al. (2005) with different participants and one different AAC device. Two of the devices in this study have been investigated in previous research (i.e., Picture Communication Board and Mini-MessageMate). The third device used in this study was a more sophisticated device, the Cyrano Communicator. The research questions investigated in this study were (a) Can two boys with significant intellectual disabilities learn to use and then choose among different AAC devices? and (b) Can The participants be taught to use their preferred devices for more functional communication?
