Action type and goal type modulate goal-directed gaze shifts in 14-month-old infants.
Ten- and 14-month-old infants' gaze was recorded as the infants observed videos of different hand actions directed toward multiple goals. Infants observed an actor who (a) reached for objects and displaced them, (b) reached for objects and placed them inside containers, or (c) moved his fisted hand. Fourteen-month-olds, but not 10-month-olds, anticipated the goal of reaching actions but tracked all the other actions reactively. Fourteen-month-olds also produced more anticipatory gaze shifts during containment compared with displacement and differentiated between reaching actions dependent on whether the overall goal was to displace objects or place objects inside containers. These results demonstrate that action type and goal type modulate the latency of goal-directed gaze shifts in infants.
