This article presents our response to the comments of Baron-Cohen, Harris, Hobson, and Leslie and Happé. We suggest that a singular cognitive hypothesis does not provide a parsimonious explanation of autism. We argue that certain aspects of autism, including observations of joint-attention deficits and observations of deficits in the prosodic elements of speech, may best be explained in terms of both cognitive and affective factors. We also acknowledge the validity of the criticism of our contingency processing deficit hypothesis (Mundy & Sigman, 1989a). In response to this criticism, we offer a modification of our model of joint-attention skill deficits in autistic children.
