The current study evaluated a procedure used to teach two children with autism to ask "why" questions maintained by causal information about an event. To increase the value of information as a reinforcer, the experimenter denied access to preferred items and did not provide a reason for the denial. Participants were taught to ask…

For most children with autism spectrum disorder (ASD), manding for information is an important skill that must be systematically taught. Although previous studies have evaluated interventions for teaching other mands for information, to date no studies have demonstrated effective procedures for teaching the mand "why?" The purpose of the…

Children with autism spectrum disorder (ASD) often display impairments in communication, such as limited echoic behavior, few vocal-verbal responses, and a lack of functional communication. One potential way to foster the acquisition of vocal responses in individuals with disabilities is by conditioning vocalizations as reinforcers. Conditioning…

Members (behaviors) of a response class are equivalent in that they produce the same functional reinforcer. Oftentimes, some members of a response class occur at higher rates than others. This can be problematic when the members that occur at high rates are socially inappropriate (e.g., self-injury, aggression, or disruption). The participant in…

More is known about how to reduce challenging behavior with functional communication training (FCT) than how to mitigate its resurgence during or following a course of treatment. Research suggests reinforcing mand variability during FCT may mitigate the resurgence of challenging behavior, but validated procedures for reinforcing mand variability…

Bidirectional naming (BiN) is the integration of speaker and listener responses, reinforced by social consequences. Unfortunately, these consequences often do not function as reinforcers for behavior in children with autism. Accordingly, the repertoire of BiN is also often limited in these children. Previous research has suggested that so-called…

People diagnosed with autism spectrum disorder (ASD) may need specific teaching to learn mands for information. Unfortunately, little research has been published on methods for teaching the mand "When?" to this population. The purpose of the current study was to replicate and extend previous research by teaching 3 children diagnosed with…

Most verbal behavior curricula for children with autism spectrum disorder (ASD) focus on teaching multiple mands during the early stages of training (e.g., picture exchange communication system; Bondy & Frost, 1994). However, few, if any, of those curricula train children with ASD to differentially mand only for reinforcers that are reasonable…

Teaching complex intraverbal responding to children with autism spectrum disorder (ASD) can be challenging and often requires careful programming. Divergent and convergent multiple control are particularly important elements to incorporate into intraverbal training programs, as well as procedures to ensure responding is under control of both…

Sundberg and Michael (2011) reviewed the contributions of Skinner's (1957) "Verbal Behavior" to the treatment of language delays in children with autism spectrum disorder (ASD) and discussed several aspects of interventions, including mand training, intraverbal repertoire development, and the importance of using Skinner's taxonomy of…

B. F. Skinner's (1957) "Verbal Behavior" had a limited influence on empirical research in the first few decades following its publication, but an increase in empirical activity has been evident in recent years. The purpose of this article is to update previous analyses that have quantified the influence of "Verbal Behavior" on…

Naming refers to the incidental acquisition of word-object relations as listener and speaker without explicit reinforcement. To investigate possible sources of reinforcement for naming, we examined the effects of a procedure for conditioning reinforcement for observing responses on the emergence of naming in children who previously lacked it. The…

The current investigation evaluated the effects of extinction and prompts on training and generalization of peer-directed mands for preferred items using a picture exchange communication system with 2 children diagnosed with autism. Results showed that independent mands with a peer increased during treatment for both participants, generalized to a…

Mand training is often a primary focus in early language instruction and typically includes mands that are positively reinforced. However, mands maintained by negative reinforcement are also important skills to teach. These include mands to escape aversive demands or unwanted items. Another type of negatively reinforced mand important to teach…

Children with autism often do not learn to mand for information without structured teaching. Studies have demonstrated that manipulation of establishing operations (EOs), prompts, prompt fading, and differential reinforcement are effective in teaching children with autism to ask "wh" questions such as "what," "who," and "where." To date, no…
