A question about Autism

Could Autistic Spectrum Disorder, ASD, involve a failure with respect to the ‘pragmatic’ or ‘Fit’ apparatus, with some individuals not inheriting the complete apparatus? Could a developmental failure with respect to Fit as an essential component of language, and its pronoun component in particular, be expressed as ASD?

Missing a step or a mis-step?

ASD is a complex disorder limiting social skills and the ability to cope with changes of routine. It used to be thought that another character of ASD was a problem with play.

If by some genetic mischance any aspect of the Fit apparatus fails to develop correctly, everyday interaction is compromised, and the consequences for the individual will be serious. If the whole apparatus is disabled, the handicap is severe. I ask whether a defect here might characterise ASD.

What would be the direction of causality? Would the social aspects of ASD obstruct the development of the Fit apparatus? Or the other way round? This and whether there is a contribution here to the management and treatment of children on the ASD spectrum I leave here as open questions.
