Abstract: One of the main difficulties in children with Pervasive Developmental Disorder (PDD) is social interaction. Eye tracking research in PDD population has shown the possibility of quantifying their social phenotype. The objective of the present paper is to access differences on perception of social pictures (faces) and non-social pictures (objects) for people with PPD and people with normal development. The research included eleven male individuals with PDD that were age, gender and intectually pared with a control group. Tobii® 1750 was the computerized equipment used to register the eye tracking movements. The perceptual pattern of individuals with PDD had more omissions (t[20] = 2,362; p = 0.028) and less use of organized tracking strategies (t[20] = 4,249; p < 0.000). Analysis of the tracking pattern revealed that PDD subjects tended to be less organized when exploring the pictures leading to perception omissions. These patterns are important to understand social patterns in persons with PDD.
