Communication deficits in children with Autism Spectrum Disorder (ASD) can manifest in a myriad of lifelong social and educational challenges. Many children with ASD fail to learn vocal verbal behavior and may require intensive individualized intervention to learn early verbal operants. The current research aimed to evaluate the effects of a…

We evaluated the use of a blocked-trials procedure to establish complex stimulus control over intraverbal responses. The participants were four young boys with a diagnosis of autism who had struggled to master intraverbals. The blocked-trials procedures involved presentation of stimuli in separate trial blocks. The trial blocks gradually reduced…

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…

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…

Shaping functional vocal language is difficult when an individual has not yet acquired an echoic repertoire and does not emit sufficient phonemes (i.e., speech sounds) for shaping. Few studies have evaluated interventions to increase the frequency and breadth of phonemes. The current study extended Esch, Esch, and Love (2009) by evaluating the…

Many children with severe developmental disabilities emit idiosyncratic gestures that may function as verbal operants (Sigafoos et al., 2000). This study examined the effectiveness of a functional analysis methodology to identify the variables responsible for gestures emitted by 2 young children with severe developmental disabilities. Potential…

In the behavioral literature, self-echoic behavior has been hypothesized to play an important role in, for example, emergent conditional discriminations (e.g., Lowenkron, 1991), emergent verbal operants (Horne & Lowe, 1996), and problem solving (Skinner, 1957). Although early behavioral intervention programs for children with autism emphasize the…

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…
