Perceptual role taking and protodeclarative pointing in autism

Abstract:

In previous studies we have found that autistic children were severely impaired in conceptual role taking, that is, in their theory of mind. In this study we consider two possible precursors to this impairment, both of which are early interpersonal abilities. The first is perceptual role taking. A test of this revealed no impairment, ruling it out as related to the impairment in theory of mind. The second is pointing. This was shown to be abnormal, both in comprehension and production, relative to non‐autistic controls. In particular, protodeclarative pointing was impaired whilst protoimperative pointing was not. The possibility that impaired protodeclarative pointing may be a precursor to autistic children's impaired theory of mind is discussed.
