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…

The current study combined equivalence-based instruction and instructive feedback (IF) with two groups of children with autism spectrum disorder. For group 1, three sets of three targets were tested, and for group 2, two sets of three targets were tested. For each target stimulus, the following verbal operants were evaluated: (1) tact name, (2)…

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…

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…

Generalization is a critical outcome for individuals with autism spectrum disorder (ASD) who display new skills in a limited range of contexts. In the absence of proper planning, generalization may not be observed. The purpose of the current study was to directly compare serial to concurrent multiple exemplar training using total training time per…

Previous research has evaluated contrived motivating operations to teach mands for information. However, literature evaluating acquisition of the mand "when?" is comparatively limited. As an extension of Shillingsburg, Bowen, Valentino, & Pierce (2014), we taught three children with autism to engage in mands for information using…

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…

Background: Two procedures were developed to teach individuals with Autism Spectrum Disorders labels (tacts) for various private events (emotions): Study 1 attempted to distinguish them from pure tacts and mands (requests); and Study 2 attempted to train initiating a conversation with grammatically correct subject-verb-comment construction.…

The purpose of the current paper is to describe the impact of applied behaviour analysis on language treatment for children with autism spectrum disorders (ASDs) diagnoses. Specifically, this paper will describe Skinner's theory of verbal behaviour and its contributions to evidence-based treatments for communication deficits among individuals with…

Children with autism spectrum disorder (ASD) often have difficulty inferring the private events of others, including private verbal behavior (e.g., thoughts), private emotional responses, and private establishing operations, often referred to as "perspective taking" by the general psychology community. Children with ASD also have…

We investigated the influence of motivating operations on the generalization of newly taught mands across settings and communication partners for 3 children with autism. Two conditions were implemented prior to generalization probes. In the first condition, participants were given access to a preferred item until they rejected the item (i.e.,…

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…

Past research has shown that response interruption and redirection (RIRD) can effectively decrease automatically reinforced motor behavior (Hagopian & Adelinis, 2001). Ahearn, Clark, MacDonald, and Chung (2007) found that a procedural adaptation of RIRD reduced vocal stereotypy and increased appropriate vocalizations for some children, although…

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…
