"The schizotypal may misread a simple non-verbal communication cue, such as a frown, as someone being displeased with them, when in reality it may have nothing to do with them. Their perceptions are often distortions of what is really happening externally, but they tend to believe their perceptions more than what others might say or do."
I remember reading that ASD people tend to do the same thing. So is there any difference with regards to this misinterpretation between the two disorders?
