An extension of incidental teaching procedures to reading instruction for autistic children.

In an extension of incidental teaching procedures to reading instruction, two autistic children acquired functional sight-word reading skills in the context of a play activity. Children gained access to preferred toys by selecting the label of the toy in tasks requiring increasingly complex visual discriminations. In addition to demonstrating rapid acquisition of 5-choice discriminations, they showed comprehension on probes requiring reading skills to locate toys stored in labeled boxes. Also examined was postteaching transfer across stimulus materials and response modalities. Implications are that extensions of incidental teaching to new response classes may produce the same benefits documented in communication training, in terms of producing generalization concurrent with skill acquisition in the course of child-preferred activities.
