Teaching Mands for Information Using "Why" to Children With Autism.

Mands for information (MFIs) play an important role in language development and are important for successfully acquiring new information from one's environment. Yet many individuals with autism do not acquire mands for information without direct teaching. Research has demonstrated effective procedures for teaching all "wh" forms, except for "why." This study investigated procedures to teach the MFI "why" under control of the establishing operation and examined the extent to which teaching resulted in generalization. The intervention was effective in establishing the MFI "why" for 3 children with autism, and generalization to novel scenarios occurred for all participants. © Association for Behavior Analysis International 2019.
