This experiment investigates the role of eye direction in infant joint visual attention. Sixty‐three infants aged from 8 to 19 months participated in a training study in which they were shown adult eye turns in association with the appearance of an interesting sight to one or the other side. It was only at 18–19 months of age that infants showed a reliable ability to use the adult eye turns to predict the side of appearance of the target. this finding suggests that before 18 months of age, infants do not recognize the significance of eye direction for joint visual attention.
