Objectives: The main objective is to study the effect of induced emotion in the children with ASD on his visual exploration strategies. We assume that the direction of gaze to photographs of different emotional valences in individuals with ASD is not changed by the emotional state in which they are located. We will compare a population of children with PDD in a control population matched for age, sex. Our secondary goal is to study the link between 1) the socio adaptive level (measured by the Vineland 2) the intensity of autistic symptoms (score ADI) and gaze orientation towards social subjects with visual stimuli.
