In humans, eye contact is the center of the attachment system. In Asperger's Syndrome there is either an avoidance of eye contact (most common) or an unvarying, relative unblinking, staring, constant eye contact (less common). Avoidant eye contact gives an impression of 'having something to hide', and also eliminates a big channel of communication and trust. Staring eye contact, because of its unchanging nature, is also uncommunicative, and is generally experienced as disturbing on the receiving end.
