SUMMARY Schizoid children (clinically resembling Asperger's autistic psychopaths), high‐grade, speaking autistic children and normal children individually matched for age, sex and intelligence were compared on a variety of tests. The results suggest that children with schizoid personality disorder are distinct from autistic children on the one hand and from normal children on the other. In all cognitive, language and memory tests the schizoid children were more distractable than, the normal group. In language function they showed similar disabilities to the autistic group, though to a lesser extent. Unlike autistic children, they were not perseverative. On two tests of affect, the schizoid group used even fewer emotional constructs when describing people than did the autistics.
