Adults labelled as odd, weird or arrogant may be subliminally autistic. These adults are usually intelligent and often financially successful, but do not understand subtle aspects of interpersonal relationships or see the social inappropriateness of their behaviour. They may appear to lack common sense; heavy reliance on stored images and learned behaviours does not serve them adequately in novel social situations.
Autistic adults may have pronounced computer-like talents, such as holding a lot of details in their head at once, or being able to recall memories as exact images rather than as words.
One study established tentative links between subliminal autism in parents and full-blown autism in their 380 children.
