Born with autism, both Temple Grandin and Sean Barron now live famously successful social lives. However, their paths were quite different. Temple’s logical mind controlled her social behavior. She interacted with many adults and other children, experiencing varied social situations. Logic informed her decision to obey social rules and avoid unpleasant consequences. Sean’s emotions controlled his social behavior. Baffled by social rules, isolated and friendless, he made up his own and applied them to others. When they inevitably broke his rules, he felt worthless and unloved.
