The lack of demonstrated empathy is possibly the most dysfunctional aspect of Asperger syndrome.[2] Individuals with AS experience difficulties in basic elements of social interaction, which may include a failure to develop friendships or to seek shared enjoyments or achievements with others (for example, showing others objects of interest), a lack of social or emotional reciprocity, and impaired nonverbal behaviors in areas such as eye contact, facial expression, posture, and gesture.[1]
Unlike those with autism, people with AS are not usually withdrawn around others; they approach others, even if awkwardly. For example a person with AS may engage in a one-sided, long-winded speech about a favorite topic, while misunderstanding or not recognizing the listener's feelings or reactions, such as a need for privacy or haste to leave.[8] This social awkwardness has been called "active but odd".[1] This failure to react appropriately to social interaction may appear as disregard for other people's feelings, and may come across as insensitive
