“…In young children with autism, a correlation between impaired performance on an EF task (spatial reversal) and an aspect of social communication (joint attention) has been reported (McEvoy, Rogers, & Pennington, 1993). Abstract language processing and discourse behavior are often disrupted in individuals with injuries to the frontal lobes (e.g., Liles, Coelho, Duffy, & Zalagens, 1989;Pearce, McDonald, & Coltheart, 1998), which are key to intact executive function (e.g., Mishkin, 1964;Iversen & Mishkin, 1970;Fuster, 1980;Diamond & Goldman-Rakic, 1989;Shallice, 1982;Milner, 1963Milner, , 1982. Likewise, there is a considerable relationship between prefrontal brain injury and social dysfunction, including theory of mind and social discourse (Anderson, Damasio, Tranel, & Damasio, 2000;Barkely, Grodzinsky, & DuPaul, 1992;Eslinger & Biddle, 2000;Rowe, Bullock, Polkey, & Morris, 2001;Williams & Mateer, 1992).…”
