Earlier autism diagnosis, the importance of early intervention, and development of specific interventions for young children have contributed to the emergence of similar, empirically supported, autism interventions that represent the merging of applied behavioral and developmental sciences. “Naturalistic Developmental Behavioral Interventions (NDBI)” are implemented in natural settings, involve shared control between child and therapist, utilize natural contingencies, and use a variety of behavioral strategies to teach developmentally appropriate and prerequisite skills. We describe the development of NDBIs, their theoretical bases, empirical support, requisite characteristics, common features, and suggest future research needs. We wish to bring parsimony to a field that includes interventions with different names but common features thus improving understanding and choice-making among families, service providers and referring agencies.

Individuals with autism exhibit significant deficits in imitation skills. This article reviews the importance of imitation in typical development, focusing on the social function of imitation and its role in the development of social communication skills. Second, it reviews evidence suggesting an association between imitation deficits and social communication impairments in children with autism. Third, it discusses limitations of the current method for teaching imitation that targets only the learning function of imitation. Finally, it describes a new imitation intervention designed to teach the social use of imitation in young children with autism.
