Eye-tracking software shows an infant's visual fixation on a bottle.
Since 6 to 9-month-old babies normally lack language skills, researchers used eye-tracking software to gauge an infant's visual fixations on named pictures as a test of his or her word understanding. Here, a parent asks an infant to look at the bottle and the eye-tracking software measures the response.
