Discuss the development of cooing and babbling in hearing and deaf infants
What will be an ideal response?
Before babies say their first word, they make impressive language progress. They listen attentively to human speech, and they make speechlike sounds. Around 2 months, babies begin to make vowel-like noises, called cooing because of their pleasant "oo" quality. Gradually, consonants are added, and around 6 months, babbling appears, in which infants repeat consonant–vowel combinations in long strings, such as "bababababa" or "nanananana." Babies everywhere (even those who are deaf) start babbling at about the same age and produce a similar range of early sounds. But for babbling to develop further, infants must be able to hear human speech. In hearing-impaired babies, these speechlike sounds are greatly delayed. And a deaf infant not exposed to sign language will stop babbling entirely. As infants listen to spoken language, babbling expands to a broader range of sounds. Deaf infants exposed to sign language from birth and hearing babies of deaf, signing parents produce babblelike hand motions with the rhythmic patterns of natural sign languages. This sensitivity to language rhythm—evident in both spoken and signed babbling—supports both discovery and production of meaningful language units.
