Brief Report: Increasing Intraverbal Responses to Subcategorical Questions via Tact and Match-to-Sample Instruction

The purpose of the study was to evaluate the effects of tact and match-to-sample instructions on the increase and maintenance of intraverbal responses to subcategorical questions (i.e., naming multiple items in a subcategory of a category). Three Chinese children on the autism spectrum (2 boys, 1 girl, aged 6–8 years old) participated in this study. Results indicated that intraverbal responses to subcategorical questions emerged or increased for most subcategories for all three participants following the completion of instruction without direct training.
