Document Summary
Children seem to act like e cient linguists equipped with a perfect theory of language, who use this theory to construct the grammar of the language they hear. Stages of language acquisition all over the words are similar. Earliest cries, whimpers are coos are stimulus driven. Noises produced by infants in all language communities sound the same. Children who are born deaf also produce these sounds therefore innate behaviour. Newborns respond to phonetic contrasts even when the di erences are not phonemic in the language spoken in the baby"s home. Japanese babies can initially distinguish r and l unlike adults. Attention to phonetic contrasts is measured by recording changes in sucking rate. Speech perception studies in pre-linguistic infants are conducted using. Habituation - dishabituation" where a teat wired to computer record their sucking rate which increases when they are interested in something sucking rate when new phoneme is introduced.
