Teaching generalized question‐discrimination skills to children with autism: Conceptual and applied considerations

Facilitating the emergence of intraverbal tacts by autistic children via joint control

Rodriguez et al. (2022) discovered that teaching four component skills was sufficient to facilitate the emergence of intraverbal tacts across four applications with three participants. Our study replicated and evaluated an extension of this procedure that was directed at facilitating intraverbal tacts when a child learns the component skills but continues to fail to produce intraverbal tacts. The extension consisted of procedures to enhance the divergent control exerted by the auditory stimulus (i.e., the question) and the discriminability of joint control. Intraverbal tacts emerged for all three participants after undergoing the extension procedures. These results are discussed in the context of a conceptual analysis of intraverbal tacts and the potential role of joint control.

The Use of Instructive Feedback to Promote Emergent Tact and Intraverbal Control: A Replication

Instructive feedback (IF) involves incorporating additional acquisition targets into skill-acquisition programs. A recent study by Frampton and Shillingsburg (2020) found that IF led to emergent verbal operants with two elementary-aged children diagnosed with autism spectrum disorder (ASD). The current study replicated Frampton and Shillingsburg with two children with ASD. Therapists conducted sessions of mastered listener-by-name trials (e.g., "Show me otter," with pictures of otter, dog, and elephant) with IF statements for features of the target stimuli (e.g., "It lives in rivers.") embedded during the consequence portion of the trial. We evaluated the acquisition of secondary targets and emergent responses using a concurrent multiple baseline across sets design. We observed increased correct responding for secondary targets and emergent responses for all three sets of stimuli with one participant. The other participant emitted correct responses for secondary targets and emergent operants with the first set but not with the other two sets of stimuli. Results suggested that IF can lead to emergent verbal operants, but the extent of emergence may be idiosyncratic.

Jack Michael's Contributions to the Treatment of Autism

Jack Michael dedicated his life to teaching behavior analysis. He was passionate about Skinner's works and his enthusiasm was contagious. Jack's primary goal for his students was that they be able to analyze behavior like Skinner analyzed behavior, but with a little bit of Jack Michael sprinkled in here and there. Jack is probably best known to behavior analysts for his conceptual contributions to our field (e.g., his work on motivation), but his contributions to the treatment of autism are perhaps his most socially significant achievement. In our tribute to Jack, we will describe how he advanced the treatment of autism not only through his conceptual work and his teaching, but through his role in the development of applied behavior analysis, and in the application of Skinner's (1957) analysis of verbal behavior to language assessment and intervention for children and adults with language delays.
