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…

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…

Manding for preferred items and activities is a critical skill for young children with autism spectrum disorder (ASD). However, little research has evaluated procedures to teach children with ASD to mand with their peers. This study evaluated the effects of a teaching package involving least-to-most prompting to increase peer-directed vocal…

Effective strategies to address communication and behavior challenges are critical in early intervention programs. The purpose of this study was to investigate the effects of the Picture Exchange Communication System (PECS) on vocal mands and aggressive behavior displayed by a child with autism in China. One 4-year-old boy with autism participated…

Adults with autism spectrum disorder (ASD), who were interested in working as behavior technicians for young children with autism, participated in 2 experiments. Participants included 5 adults with Asperger syndrome or pervasive developmental disorder not otherwise specified, 19 to 23 years old, and 11 children with autism, 3 to 7 years old. In…

Children with autism often demonstrate less variable behavior than their typically developing peers and those with other cognitive disabilities. A possible reason for lack of response variability emitted by children with autism is that they do not have a variety of response forms in their repertoire. Multiple-exemplar training through the use of…

With the number of students with autism and related developmental disabilities increasing and a lack of trained professionals, solutions are needed to provide training on a large scale. Alternative training approaches need to be developed so that paraprofessionals can access training in an efficient and effective way. One such possibility is…

A primary deficit seen in many children with autism, particularly those with limited verbal repertoires, is repetitive and rote verbal behavior. This type of repetitive or rote verbal behavior can be stigmatizing and may severely limit access to primary reinforcers. Therefore, it may be beneficial to attempt to increase response variability in…

The year 2007 marked the 50th anniversary of the publication of B. F. Skinner's "Verbal Behavior", a book that by Skinner's own account was his most important. The received view, however, is that a devastating review by a young linguist not only rendered Skinner's interpretation of language moot but was also a major factor in ending the hegemony…

Children with autism and related disabilities frequently fail to develop echoic repertoires. Among the ways in which treatment approaches vary is the extent to which automatic reinforcement is utilized. The present experiment was designed to test the efficacy of a procedure that incorporates automatic reinforcement and socially mediated…

Skinner's conceptual analysis of language has influenced one model of early and intensive behavioral intervention with children, which incorporates verbal operants including mands, tacts, intraverbals, etc. Many studies have examined the mand and tact relations, with little focus on teaching intraverbal behavior. In the present experiment,…

Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the…

Mand functions for two stimuli (A1 and A2) were trained for 3 children with autism and were then incorporated into two related conditional discriminations (A1-B1/A2 -B2 and B1-C1/B2-C2). Tests were conducted to probe for a derived transfer of mand response functions from Al and A2 to C1 and C2, respectively. When 1 participant failed to…
