Infants were habituated to the event shown in (a), a hand repeatedly reaching for a ball on one side of a display. When tested later with displays (b), (c), and (d), infants who saw the hand reach for the other object looked longer than did those who saw it reach for the ball (regardless of the ball's position). The pattern of results indicates that the babies interpreted the original reaching as object–directed. (Adapted from Woodward, 1998)
