TL;DR

It is concluded that autism and dysphasia differ in important ways and that a cognitive deficit is an essential part of the syndrome of autism.

Abstract

A psychometric, observational, and interview study was undertaken with 47 boys, aged 4 1/2 to 10 years, with nonverbal IQs of 70+ and a severe developmental disorder of language comprehension. Separate discriminant function analyses, based on behavioral, language, or cognitive features, showed little overlap between clinically defined autistic and dysphasic subgroups. Moreover, the discrimination could be made as clearly on language or cognitive characteristics as on social or behavioral critera. Language abnormalities and behavioral features also intercorrelated within the autistic subgroup. It is concluded that autism and dysphasia differ in important ways and that a cognitive deficit is an essential part of the syndrome of autism.

Several methods of estimating error rates in Discriminant Analysis are evaluated by sampling methods, finding the two methods in most common use to be significantly poorer than some new methods that are proposed.

Evidence and arguments are presented to support a thesis that central language deficits related to those found in children with developmental aphasia, but more severe, may be the necessary and sufficient cause of behavior which marks children as autistic and schizophrenic.

Intensive language training starting in the preschool years and possibly introduction of systematic sign language may be useful for both groups and especially valuable for aphasic children with more intact language competence.

Out of 60 children justly labelled autistic by the investigating hospitals and who could not communicate by speech, 16 were actually suffering from severe executive aphasia which was found to be of a secondary reactive nature.
