People on the Autistic Spectrum.

Autistic spectrum disorders (ASD) are a range of social and communication disorders including autism and Asperger syndrome. People with ASD can be unaware of body language and social boundaries. They are likely to use language literally, and may misinterpret what is being said due to difficulties recognising facial expressions, tone of voice and intonation.

• Use clear and unambiguous language. Avoid using figures of speech, sarcasm or metaphors.
• Some people with ASD may avoid eye contact, and may therefore appear aloof or uninterested. Try not to take offence.
• The person may not respect your personal space and social boundaries. Correct them politely if you feel uncomfortable.
• The person may be very uncomfortable with physical contact, so ask before you shake hands, e.g., May I shake your hand?
• Do not rush the person.

People with ASD often rely heavily on routine and adapt badly to changes to this routine. Bear this is mind if there are last minute changes to schedules.
