“The idea that hyperreactivity and hyporeactivity are two variations on a theme might even have implications for theory of mind. The “Intense World” paper proposed that if the amygdala, which is associated with emotional responses, including fear, is affected by sensory overload, then certain responses that look antisocial actually aren’t. “Impaired social interactions and withdrawal may not be the result of a lack of compassion, incapability to put oneself into someone else’s position or lack of emotionality, but quite to the contrary a result of an intensely if not painfully aversively perceived environment.” Behavior that looks antisocial to an outsider might actually be an expression of fear.”
