Eye-Tracking Studies Reveal Early Autism Markers in Infants as Young as 2 Months

Understanding Neurodivergent Traits Through Eye-Tracking

Emerging research is exploring how eye-tracking tests might help identify neurodivergent traits in infants earlier than traditional methods. A study in Nature found that brief eye-tracking sessions can measure social attention patterns in babies under 12 months, potentially aiding early support strategies.

Research has shown that gaze patterns can vary among autistic individuals. Large-scale studies involving hundreds of children confirm these observations can identify neurodivergent traits with moderate accuracy as early as 7 months. Systematic reviews note that differences in attention to social cues may emerge in some infants as young as 2-6 months who are later identified as autistic.

Balancing Early Identification with Comprehensive Understanding

The research suggests a developmental period when neurodivergent traits may first become observable. A Springer study found measurable differences in social attention by 12 months. However, experts caution against overgeneralization - about 30% of autistic children show typical gaze patterns, and the technology can't distinguish autism from other developmental variations.

'These are research tools, not diagnostic tests,' explains a researcher from the Nature study. The developers of the 2-minute protocol similarly emphasize their Nature-published method is designed for screening, not diagnosis.
