Aspergers affects a persons ability to communicate. It makes it hard for people to be social. People who have aspergers lack empathy and sympathy for people. They have random outbursts, and repetitive patterns of interests and behavior. People with Aspergers are able to notice very minute changes and patterns. They can be sensitive or insensitive to light sound and other senses. When talking to people, they either force awkward eye contact or avoid eye contact completely. They have a small amount or sometimes obsessive interests. They also have a hard time understanding peoples emotions. Because of them not being able to understand emotions, people with aspergers dont usually have friends. People with Aspergers usually want to be alone or they want to interact but they don't have the ability to know how to. According to Klin J, McPartland “Childhood desire for companionship can become numbed through a history of failed social encounters.”
