Girls are more able to verbalise their emotions and less likely to use physically aggressive acts in response to negative emotions such as confusion, frustration and anger. We do not know whether this is a cultural or constitutional characteristic but we recognise that children who are aggressive are more likely to be referred for a diagnostic assessment to determine whether the behaviour is due to a specific developmental disorder and for advice on behaviour management. Hence boys with Asperger's Syndrome are more often referred to a psychologists or psychiatrist because their aggression has become a concern for their parents or schoolteacher. A consequence of this referral bias is that not only are more boys referred, clinicians and academics can have a false impression of the incidence of aggression in this population. One must always consider the personality of the person with Asperger's Syndrome and how they cope with the difficulties they experience in social reasoning, empathy and cognition.
Some individuals are overtly active participants in social situations.
Their unusual profile of abilities in social situations is quite obvious. However, some are reluctant to socialise with others and their personality can be described as passive. They can become quite adept at camouflaging their difficulties and clinical experience suggests that the passive personality is more common in girls. Each person with Asperger's Syndrome develops their own techniques and strategies to learn how to acquire specific skills and develop coping mechanisms. One technique is to have practical guidance and moral support from one's peers.
