Previous research has shown that children with autism spectrum disorder (ASD) can categorize visual stimuli without direct training when they can also tact these stimuli using a common name and behave as listeners in relation to this name. However, children usually learn to assign objects specific names prior to learning the category to which they belong. The current study replicated previous research and evaluated whether multiple-tact training would establish visual categorization (measured by a picture sorting test) and listener behavior. We used a nonconcurrent multiple baseline design across 2 children with autism spectrum disorder. After multiple-tact training, we assessed whether participants would visually categorize stimuli based on their common category name. Both participants categorized and engaged in the corresponding listener behavior.

Intraverbal behavior is a type of verbal behavior in which the response form has no point-to-point correspondence with its verbal stimulus. However, the form and occurrence of most intraverbals is under the control of multiple variables. Establishing this form of multiple control may depend on a variety of preestablished skills.

Teaching the children to use the problem-solving strategy did not produce significant increases in target responses until problem solving was modeled and prompted. Following the model and prompts, all participants showed immediate significant increases in intraverbal categorization, and all prompts were quickly eliminated.

Multiple-tact training involved teaching a child to name both the item and the category to which the item belonged. Receptive-discrimination training consisted of teaching a child to select a picture card in the presence of a question from the experimenter regarding the item or its category.
