Eye tracking has been used to investigate gaze behaviors in individuals with autism spectrum disorder (ASD).However,traditional analysis has yet to find behavioral characteristics shared by both children and adults with ASD.To take into account all of the temporo-spatial gaze patterns from all of the participants,we summarized the data using multidimensional scaling (MDS).To distinguish core ASD gaze behaviors from those that change with development,we extract the temporo-spatial gaze patterns from thedatabase of video viewing of children and adults with and without ASD.
