A preliminary study of right hemisphere cognitive deficits and impaired social judgments among young people with Asperger syndrome

Seven children and young adults with definite signs of Asperger syndrome were administered a battery of tests designed to test: intelligence; left and right cerebral hemisphere functioning; ability to discriminate eye gaze; and social judgment. The subjects revealed a non significant tendency to have a higher verbal IQ than visual IQ; and their right hemisphere functioning seemed impaired. They were also poorer at discriminating eye gaze and revealed difficulties in making hypothetical social judgments. The data are considered with reference to Rourke's (1988) work on non-verbal learning disabilities together with the ideas of Tantam (1992) on the "social gaze response" and Baron-Cohen's (1993) Eye-Detection Detector model. The possible links between social judgment and theory of mind (Frith, 1991) are briefly explored.
