Teaching children with autism to answer novel wh-questions by utilizing a multiple exemplar strategy

This study investigated the transfer and maintenance of question-answering skills in five children diagnosed with autism. A multiple baseline design across classes of questions (i.e., what, where, who and why) was applied for each child. Question-answer exemplars were selected within each class, and each class was trained separately in consecutive order. The dependent variable was the proportion of appropriate answers (i.e., complete sentences) to novel questions within each class, on first trial. The results showed that all children became able to answer novel questions with complete sentences within each of the classes that were trained, and they showed transfer of these skills across persons, settings and time. The findings support the use of analogous question-answer exemplars in order to facilitate response-transfer to novel questions. It is also suggested that this type of transfer is more likely to occur if the answers trained are in full sentence and there is a structural correspondence between the question and the answer in each single exemplar and across exemplars within a class of questions.
