Being fun is not commonly regarded as a trait of Asperger’s Disorder children or teens. They typically have limited emotional engagement with their peers and low emotional expression.
They do not seek to share excitement and do not respond to their peers’ indications of pleasure. They do not often approach others and invite them to have fun. Their emotions are typically blunted during play and activities, and whatever joy they experience is hard to detect. If the playmate feels he is the only one having fun, it dampens the overall experience and will probably prevent another invitation to get together. The Asperger’s Disorder child, however, will report that he had fun and will be left bewildered as to why the peer never invited him to get together again.
Expression of negative emotions is the opposite of how the Asperger’s Disorder child displays his joy. Anger and frustration are frequently displayed by the Asperger’s Disorder child, and is often the reason his playmate looks elsewhere for a friend. His expression is likely to be quick to surface, as well as an overreaction to the situation. He will have trouble bringing his upset to closure and moving on.
