Abstract
This study tracked eye movement in children with and without autism spectrum disorder (ASD) watching emotional biological and non-biological motion point-light-displays (PLDs). Older children with ASD focused on extremities while older typically developing (TD) children looked at figure’s heads, whereas not evident in the younger groups. These results suggest developmental advances in social-information biases in TD children not evident in children with ASD, together with atypical and potentially adaptive increases in attentional biases towards local motion cues with age in ASD. Potential avenues for future computational and methodological analyses are discussed.
