{"product_id":"9780521872973","title":"Language Development and Age","description":"\u003cp\u003eThe anecdotal view of language acquisition is that children learn language with apparent ease, no instruction and in very little time, while adults find learning a new language to be cognitively challenging, labour intensive and time-consuming. In this book Herschensohn examines whether early childhood is a critical period for language acquisition after which individuals cannot learn a language as native speakers. She argues that a first language is largely susceptible to age constraints, showing major deficits past the age of twelve. Second-language acquisition also shows age effects, but with a range of individual differences. The competence of expert adult learners, the unequal achievements of child learners of second languages, and the lack of consistent evidence for a maturational cut-off, all cast doubt on a critical period for second-language acquisition.\u003c\/p\u003e","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":45389418889295,"sku":"00000_00000_00000_00000","price":4795.0,"currency_code":"TWD","in_stock":true}],"url":"https:\/\/kinokuniya.com.tw\/ja\/products\/9780521872973","provider":"Books Kinokuniya Taiwan","version":"1.0","type":"link"}
