To examine potential eye-tracking based markers for social processing deficits in children with autism spectrum disorder (ASD). To this end a battery of five eye tracking paradigms assessing social functioning will be evaluated in young children with ASD and compared with data from typically developing children. To additionally evaluate the specificity of the markers a group of children with disorders of delayed development other than ASD will be included.
During an initial screening session all participants will undergo assessments to validate the diagnosis and ASD-related symptoms using the Autism Diagnostic Observation Schedule (ADOS), Social Responsibilities Scale 2 (SRS 2), Caregiver Strain Questionnaire (CSQ), Aberrant Behavior Checklist (ABC), Social Communication Questionnaire (SCQ) and Repetitive Behaviour Scale Revised (RBS-R).
Next, all participants will undergo the following five eye-tracking paradigms assessing social perception: (1) dynamic social-nonsocial visual preference task during which movies of dynamic geometric images (DGI) and dynamic social images (DSI) will be presented; (2) non-biological versus biological motion task; (3) social attention and motivation of sharing enjoyment; (4) preference for emotional faces versus schematic faces (emoticons); (5) shared social attention - shared gaze direction with an actor shifting his attention to different objects.
