Abstract:
Ingvarsson and Hollobaugh (2011) investigated tact- or echoic-to-intraverbal transfer of stimulus control to "wh" questions for three preschool-aged boys with autism. The current study was a systematic replication of this study with an adolescent girl with Down syndrome. A multielement design was used to compare the effectiveness and efficiency of picture or echoic prompts presented on an iPad or in vivo to teach "wh" questions. All prompt conditions were effective. Conclusions and recommendations for practice are presented.
