Viewing the social scene, the abstract scene, the center of the screen or being distracted during the first 15, first 30 or the entire 50 s of the video in visit 1. Example: Children with ASD and TD children, respectively, gazed at the social scene 30.1% and 50.1% of all frames during the first 15 s of the video
