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.

Conditions

Interventions

BEHAVIORAL

Attentional Blink task

The Attentional Blink task presents rapid sequences of images (including two targets and distractors), measuring the minimum time delay required for both targets to be detected. Three different T1-T2 intervals are tested.

BEHAVIORAL

Temporal Integration Window task

The TIW task involves alternating visual displays (integration and segmentation trials) across four inter-stimulus intervals (ISI: 16, 32, 83, 116 ms). This task allows estimation of the participant's perceptual integration threshold.
