We investigated whether a child with Asperger?s Syndrome would demonstrate deficits in awareness of cognitive processing similar to those demonstrated for awareness of social interactions. The cognitive processes examined were memory and metamemory, or knowing about knowing. With regard to procedural metamemory, the child was unable to accurately predict his own memory, particularly which items he would not be able to recall. Declarative metamemory also was impaired. Tasks requiring imitation of the researcher or that were largely nonverbal resulted in particularly poor performance. The findings indicate that the child?s social deficits related to Asperger?s Syndrome extended to the cognitive domain. Overall, a deficit in cognitive awareness was observed.
