title: Space perception in early infancy: perception within a common auditory-visual space.
abstract: Infants as young as 30 days become visibly distressed upon observing their mothers speak to them while the mother's voice is displaced in space. Their ability to perceive this discrepancy indicates that infant perception occurs within a space that is common to the visual and auditory modes.
