Study: Speaking ‘Parentese’ Helps Baby’s Language Learning
By Bryan Lynn
29 January, 2019
It is common for adults to use "baby talk" when interacting with very young children. This way of speaking attempts to copy the sounds babies make when they first try to talk. But is this form of communication helpful to a child's development?
interact v. 互动
Several studies have suggested a clear link between parental language methods and a child's early language development.
parental adj. 父母的
Studies showed that language learning in babies was improved when parents spoke more than a few simple words and used a wider vocabulary. Earlier research found that the style of speech used by parents to communicate with their baby could increase language development.
vocabulary n.词汇量
style n.方式； 方法
One such speaking style is known as "parentese." Research has shown that babies react better to this kind of language in the first months of life.
parentese n.父母语言
react vi. 反应，作出反应
Generally, parentese involves adults speaking in a higher voice and at a slower speed. The language is simplified, while sentences are short and often repeated. Studies from the past 30 years have /confirm/ied that babies spoken to in parentese developed larger vocabularies throughout the first three years of life.
involve vt. 包含； 使参与，牵涉
simplify vt.简化； 使单纯； 使简易
confirm v.确认， 证实
A new study on the subject examined whether parents can be effectively taught methods to improve their parentese skills. The study was a project of the University of Washington's Institute for Learning & Brain Sciences.
effectively adv.有效地
