Abstract

The influence of quantity and quality of early language exposure on children's language development is crucial.The quantity and quality of language input should be adjusted in a timely manner depending on children's developmental age.The quantity of parent's language input is the most important for children under 18 months old.The diversity and sophistication of words that parents produced,specifically the adult-child conversational turns,play a vital role for children at 30 months old.And the input of narrative and explanation utterances is principal for children at 42 months old.However,screen exposure and electronic(sounding) toys do more harm than good to children's language development and parent-child interactions.And children in low-educated families are particularly vulnerable to early screen exposure.

Key words

language exposure / development / word type / conversational turns / word recognition / screening exposure / structural neural connectivity
