Like the visual system, the auditory system is also functional at birth and is fast developing. Fetuses hear before birth: They react to [[sounds]] by moving around, and their [[heart]] rate increases. Newborns recognize stories that their mothers repeatedly read out loud before they were born, and they prefer to listen to their mothers' [[voice]]s over those of stranger. Newborns also prefer infant-directed [[speech]] over adult-directed speech. Infant-directed speech (motherese, parentese) is high in [[pitch]], is slow, and has exaggerated rises and falls. This speech may help infants with [[language]] acquisition by directing their attention to particular [[words]]. | Like the visual system, the auditory system is also functional at birth and is fast developing.
