Plain-language summary

This study investigates the temporal dynamics of perception and attention in children with Autism Spectrum Disorder (ASD), focusing on two key phenomena: the Temporal Integration Window (TIW) and the attentional blink. Using eye-tracking, 3- and 5-year-old children with ASD (prototypical or not) will be compared to age-matched neurotypical peers. The investigators hypothesize that children with ASD exhibit shorter TIWs and attentional blinks, reflecting faster perceptual sampling and attentional processing. These characteristics may contribute to sensory hypersensitivity and difficulties in complex, unpredictable environments such as social situations. The protocol includes two experimental tasks.
