Eye-tracking measures in audiovisual stimuli in infants at high genetic risk for ASD: challenging issues

Individuals with autism spectrum disorder (ASD) have shown difficulties to integrate auditory and visual sensory modalities. Here we aim to explore if very young infants at genetic risk of ASD show atypicalities in this ability early in development. We registered visual attention of 4-month-old infants in a task using audiovisual natural stimuli (speaking faces). The complexity of this information and the attentional features of this population, among others, involves a great amount of challenges regarding data quality obtained with an eye-tracker. Here we discuss some of them and draw possible solutions.
