Language comprehension in autism

It has long been recognised that many people with autism have difficulty in processing semantic information. Indeed, impairments of semantic processing lie at the heart of Uta Frith’s influential ‘weak central coherence’ account of autism (Frith, 1989), which states that autism is characterised by “the inability to draw together information so as to derive coherent and meaningful ideas”. Weak central coherence remains, however, a somewhat nebulous concept and the precise nature of any semantic impairment is still unspecified. Moreover, recent studies have indicated that semantic processing difficulties may be related to an individual’s level of general language ability rather than being a generic feature of autism.
