Abstract
OBJECTIVE: The objective of our study was to compare the distribution of attention on two categories of stimuli: 1) social stimuli and 2) objects or geometric shapes, in individuals with autism spectrum disorders (ASD) and a control group. Moreover, we examined the relationship between the parameters of saccadic eye movements and the severity of ASD. Furthermore, we were interested in whether the metrics derived from saccadic eye movements could serve as useful biomarkers for autism spectrum disorder. DESIGN: There were 79 participants in the research sample, 34 in the ASD group and 45 in the control group. We used two categories of photos: a) social
