本章论述心理语言学对儿童习得母语的最新研究及其与语言教学之间的关系。在这方面已经提出了一些语言教师不能忽略的观点。这些观点简述如下: 1.语言习得是人类的普遍特征,除非失常或患障碍症。 2.第一语言习得的年龄跨度为1岁半到6岁,不会更早,个别情况下稍晚。 3.语言的发端在时间上与大脑发育的稍后阶段相联系。 This chapter discusses the latest research of psycholinguistics on children’s acquisition of mother tongue and its relationship with language teaching. In this respect, some opinions that language teachers can not ignore have been put forward. These points are summarized as follows: 1. Language acquisition is a common feature of human beings, unless abnormal or suffering from disorders. 2. The first language acquisition ages from 1 year and a half to 6 years old, not earlier and in some cases later in the year. 3. The onset of language is linked in time to a later stage of brain development.
