Looking Away from the Speaker's Mouth: A Developmental Shift from Infancy to Preschool
Our research examined where infants and children focus their attention when viewing a speaker. We hypothesized that infants would spend more time looking at the speaker’s mouth than the eyes, while preschool children would spend more time looking at the speaker’s eyes than the mouth. Using eye tracking technology, we measured gaze duration to the eyes and mouth of the speaker. The results supported our hypothesis.
