About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Children aged 3 or 5 years

Either with a diagnosis of Autism Spectrum Disorder (ASD) or typically developing (neurotypical)

No intellectual disability (per Mullen, Denver, or psychometric report)

Normal or corrected vision and hearing

Disqualifiers

Neurological disorder

Parental or child refusal to participate

For neurotypical children: developmental delay or psychiatric diagnosis

Trial design

Design model

Parallel

Treatments tested in this trial

  • Temporal Integration Window task

    Behavioral

    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.

  • Attentional Blink task

    Behavioral

    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.

Trial outcomes

Primary outcomes

1

Temporal dynamics of perception

The Temporal Integration Window (TIW) is defined as the shortest interval between two displays that can be integrated into a single percept

Time frame
Baseline
2

Temporal dynamics of attention
