Principal Component Analysis of Eye-Tracking Data during Visual Perception of Human Faces in Adults and Children with Autism

Introduction: Autism is a pervasive developmental disorder, characterized by a triad of impairments: social communication problems, difficulties with reciprocal social interactions, and unusual patterns of repetitive behavior (Wing & Gould, 1979). This study was designed to explore particularities on visual perception of persons with autism. Thus, in order to investigate the gaze behavior of autistic individuals, statistical methods were performed.
