Illustration of the eye-tracking method used to assess infant’s attention to social signals of emotion. After the infant looked at a fixation stimulus in the center of the screen (red circle), a face or a scrambled face pattern and subsequently a high-contrast lateral distractor were presented. The probability of attention disengagement from the central to the lateral stimulus was analyzed from the eye tracking data and used as a measure of attention to scrambled face patterns and neutral, happy, and fearful faces (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.).
