Establishing initial auditory-visual conditional discriminations and emergence of initial tacts in young children with autism spectrum disorder.

Children with autism spectrum disorder (ASD) often display impaired listener skills, and few studies have evaluated procedures for establishing initial auditory-visual conditional discrimination skills. We developed and evaluated a treatment package for training initial auditory-visual conditional discriminations based on the extant research on training such discriminations in children with ASD with at least some preexisting skills in this area. The treatment package included (a) conditional-only training, (b) prompting the participant to echo the sample stimulus as a differential observing response, (c) prompting correct selection responses using an identity-match prompt, (d) using progressively delayed prompts, and (e) repeating trials until the participant emitted an independent correct response.

An Evaluation of Conditional Manding Using a Four-Component Multiple Schedule.

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).
