Infant shifting attention from an adult's face to an adult's hand: a precursor of joint attention

Two experiments were designed to investigate shifting attention from an adult's face to an adult's hand by 3- and 4-month-olds. In Experiment 1, 24 infants were presented with five types of hand gestures by their mothers and a stranger. Experiment 2 was given to 22 infants with the same procedures, except for the addition of a head inclining while pointing to objects. The results were: (1) after encountering an averted head repeatedly, the infants shifted their attention from the adult's face to the moving hand and objects; they oriented to what the adult was attending to. (2) The moving head improved the rate of infants turning their heads to the same direction as the adult. The conclusion was averted head and eyes play a major role in infants' orienting to an adult's hand. A hand was a shared visual target during the adult's object performance, indicating that infants' orientation to the adults' hand is a precursor stage of joint visual attention.
