Normal development: 2 month of age: scan the eye region 4 month of age: discriminate gaze direction 6 months: readily orient attention to an object being looked at by another person, providing it is in their visual field. 9-10: follow head turn and gaze shifts spontaneously and they can search for a looked at object on the bais of head cues only 10 months: follow a protagonist head then when its eyes were open 18: follow no matter how far or where it is 24: start diagnosing autism Bhevaioral and electrophysiological studies: less interest in looking at faces in autism; look less at eye region; children with autism also engage in less mutual gaze and show deficits in gaze following behavior. Joint visual attention: looking at a object together Testing: all they able to compute eye gaze? Leekam (1997) autistic children: yes they can compute direction eye gaze! For statis picture they can, compute when it’s a static picture but when the person starting to move, they were poor at monitoring gaze and tended not to change in another person head and eye direction. Leekam 2( 1998): parent interview, direct observation and an experiment; spontaneous gaze following behavior in autism is developmentally delayed. Base line Shaping phase Test phase Mental age( both verbal and nonverbal was a significant predicator of perfiomance was a significant predictor. YES IF above AGE 4= they ability to follow eyegaze and head turn. Sgf is not impaired or absence but delayed. Joined visual Attention: similar relationship, and for theory of mind tasks.
