Preference for blocking or response redirection during stereotypy treatment

Response redirection and response blocking reduce stereotypy maintained by automatic reinforcement. The current study evaluated the effects of redirection and response blocking on the stereotypic responding of three elementary-age children diagnosed with autism. During the treatment evaluation, redirection and response blocking were evaluated using an alternating treatment embedded in a reversal design. Both procedures resulted in comparably low levels of motor stereotypy. Following treatment evaluation, a concurrent chain was conducted to evaluate participant preference for redirection or response blocking. All three participants preferred redirection. Practitioners may wish to consider participant preference when developing and implementing treatments for stereotypy. (C) 2012 Elsevier Ltd. All rights reserved.
