Use of Modified Change Over Delay Procedure to Decrease Scrolled Responses by a Child with Autism

Abstract

The term scrolling has been used by Sundberg (2008) to describe the behavior of a child emitting multiple incorrect verbal responses to a single stimulus. Sundberg noted that incorrect responses emitted are not random, but are usually previously targeted words. oScrolling must be minimized while teaching imitation skills to ensure that only correct imitation responses are reinforced. oThe purpose of the current study was to use an adaptation of the changeover delay procedure to reduce the rate of scrolling through three learned imitation responses by a child with autism in an attempt to increase correct imitations.
