According to the book I'm reading, Asperger's from the Inside Out, Individual with AS is fooled easily which kind of represents them as trusting and loyal. But negative interpretation of that they are easily duped by tricks, pranks, or scams, which are causing great social and financial harm that these confusion add possible anger and stress overload.
The differences between Autism and asperger syndrome are that autism is a lifelong disability that affects how a person makes sense of the world, processes information and relates to other people. Individual with autism have difficulties in communication, social interactions, response to sensory information, plays, behavior. Aspergers syndrome is mostly a hidden disability where you can't tell if someone has this condition or not by their appearance only that they have problem mainly in social communication, social interaction, and social imagination. Aspergers syndrome has similar symptoms but have normal language development. Also, they have difficulties in reading facial expressions, tone of voice, body languages, etc.
