The purpose of the study was to experimentally model summation in convergent multiple control over selection-based verbal behavior. Eight undergraduate students participated. In divergent--convergent tact training, a three-choice match-to-sample task was used to establish two selection-based tacts for each of five pictorial stimuli. One textual…

Deficits in communicating one's wants and needs can have significant and detrimental effects on quality of life. Particularly for individuals with autism spectrum disorder (ASD) and other related disabilities, manding is a pivotal skill that influences long-term prognosis. Mand training is complex and relies on several components to facilitate…

Since Skinner's conceptualization of the mand, applied behavior analysis researchers have used the concept to develop stimulus control transfer procedures effective for addressing manding deficits. More recently, researchers have explored the clinical utility of reinforcing mand variability during mand training and functional communication…

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…

Children with autism spectrum disorder (ASD) often show language delays. Their limited communication skill may lead them to engage in the same disruptive behavior that previously got them what they wanted. Verbal behavior (VB), specifically mand training (MT), is one of the early language intervention strategies used to target language development…

For children with developmental or language delays, mand interventions have been identified as an integral part of educational programming (e.g., Greer & Ross, 2008; Shafer, 1994; Sundberg & Michael, 2001). Mands, which are the most elementary forms of verbal behavior, allow individuals to begin to contact social contractual contingencies;…

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…

The mand is a type of verbal operant whose response form is under control of a motivating operation (MO). It is the first verbal operant to be acquired, directly benefits the speaker, leads to the development of other behaviors, and may serve to replace problem behavior. Even though the topography of the mand is under the functional control of an…

In the present essay, commemorating the 60th anniversary of the publication of B. F. Skinner's "Verbal Behavior", I stand by and defend the judgment I expressed in my article "The Long Goodbye: Why B. F. Skinner's 'Verbal Behavior' Is Alive and Well on the 50th Anniversary of Its Publication" (2008c)--that Skinner's…

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…

Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009),…

Jack Michael offered a course on verbal behavior almost every year throughout his teaching career. Jack was also interested in the application of Skinner's work and in 1976 began to offer a graduate course at Western Michigan University titled Verbal Behavior Applications. Jack and his students pursued the application of Skinner's work on verbal…

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…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…
