Ganz Texas A&M University Margaret M. Flores Auburn University Erin E. Lashley Northside Independent School District, San Ant<strong>on</strong>io, TX Abstract: Students with autism spectrum disorders (ASD) have difficulties with verbal language. Many interventi<strong>on</strong>s to remediate such deficits require numerous materials <strong>and</strong> significant teacher time. This study sought to determine if a simple multi-comp<strong>on</strong>ent interventi<strong>on</strong> that incorporated n<strong>on</strong>c<strong>on</strong>tingent reinforcement (NCR) <strong>and</strong> verbal modeling would result in increased sp<strong>on</strong>taneous verbal requesting in two preschool boys with autism. Results indicated that the participants did increase use of sp<strong>on</strong>taneous <strong>and</strong> imitated verbal requests. Implicati<strong>on</strong>s are discussed. Deficits in communicati<strong>on</strong> <strong>and</strong> speech are a hallmark of autism spectrum disorders (ASD; American Psychiatric Associati<strong>on</strong> [APA], 2000). Many individuals with ASD do not speak or have delayed communicati<strong>on</strong> skills (APA), including limited communicati<strong>on</strong> functi<strong>on</strong>s (e.g., requests <strong>and</strong> refusals; Ogletree, 2008). Some have difficulty maintaining c<strong>on</strong>versati<strong>on</strong>s <strong>and</strong> use repetitive or echolalic speech (APA; Janzen, 2003). Other aspects of speech may be delayed, including articulati<strong>on</strong>, c<strong>on</strong>tent, grammar, <strong>and</strong> using abstract c<strong>on</strong>cepts in language (Janzen). The Nati<strong>on</strong>al Research Council (2001) recommends that programming for children with ASD includes at least 25 hours per week of systematic instructi<strong>on</strong>, focusing <strong>on</strong> functi<strong>on</strong>al <strong>and</strong> sp<strong>on</strong>taneous communicati<strong>on</strong>. Such instructi<strong>on</strong> may cost up to $60,000 per year (Nati<strong>on</strong>al Research Council). Thus, it is important to determine if some children with ASD resp<strong>on</strong>d to less costly, effective strategies, which allow precious resources, including pers<strong>on</strong>nel training time <strong>and</strong> cost, instructi<strong>on</strong>al time, <strong>and</strong> materials, to be reserved for those Corresp<strong>on</strong>dence c<strong>on</strong>cerning this article should be addressed to Jennifer Ganz, Texas A&M University, Department of Educati<strong>on</strong>al Psychology, 4225 TAMU, College Stati<strong>on</strong>, TX 77843-4225.

Koegel, Koegel, Shoshan, <strong>and</strong> Mc- Nerney (1999) report that children with autism who dem<strong>on</strong>strate more frequent sp<strong>on</strong>taneous communicati<strong>on</strong>, including n<strong>on</strong>verbal communicati<strong>on</strong>, prior to communicati<strong>on</strong> treatment resp<strong>on</strong>d better to such treatment. Several methods have been proposed to replace challenging behaviors with socially acceptable communicati<strong>on</strong> skills in children with ASD. N<strong>on</strong>c<strong>on</strong>tingent reinforcement (NCR) focuses <strong>on</strong> increasing socially relevant skills <strong>and</strong> has been proven effective with individuals with a variety of disabilities. Further, elements of incidental teaching <strong>and</strong> time-delay have had promising results. Modeling of behaviors has been used to improve a variety of skills in children with ASD (Mats<strong>on</strong>, Mats<strong>on</strong>, & Rivet, 2007; Stahmer, Ingersoll, & Carter, 2003). This procedure, when used for modeling names of items for requesting, had also been called m<strong>and</strong>-modeling (Mobayed, Collins, Strangis, Schuster, & Hemmeter, 2000). Research has supported the use of in vivo modeling of peers <strong>and</strong> adults to promote labeling (Charlop, Schreibman, & Try<strong>on</strong>, 1983) <strong>and</strong> following directi<strong>on</strong>s (Egel, Richman, & Koegel, 1981). In vivo modeling has also resulted in improved play <strong>and</strong> social skills in children with autism, including dis- 596 / Educati<strong>on</strong> <strong>and</strong> Training in <strong>Autism</strong> <strong>and</strong> <strong>Developmental</strong> <strong>Disabilities</strong>-December 2011
