Abstract
The aim of this paper was to propose and present a behavior analytic teaching strategy and a behavior change plan for verbal behavior for a boy diagnosed with Autism Spectrum Disorder who displayed tantrum behaviors and maladaptive verbal manding skills. Verbal behavior assessment was conducted as well as functional behavior assessment in order to determine the status of subjectâ€™s verbal behavior and underlying function of tantrum behaviors. Results indicated that the boy had maladaptive mand behavior and that the tantrums he displayed had the function of escape. Based on these finding, an Incidental teaching strategy is proposed and discussed.
