大人经常对小孩说“吃饭饭”、“拉臭臭”之类的儿语。父母到底应不应该对孩子这样说？

我们来看一段相关的英文报道

Intonation is also very important to infants' language development in the first months of life. Adults tend to speak to babies using a special type of register that we know as baby talkor motherese.

This typically involves a higher pitch than regular speech, with wide, exaggerated intonation changes.

Research has shown that babies prefer to listen to this exaggerated 'baby talk' type of speech than typical adult-like speech: They pay more attention when a parent's speech has a higher pitch and a wider pitch range compared to adult-like speech with less exaggerated pitch features.

在婴儿几个月大的时候，语调对其语言发展非常重要。成年人经常使用特殊的语调和宝宝说话，我们称之为“儿语”或者“妈妈语”。

儿语的典型特征是比平时说话的音调更高，语调变化范围更广，更夸张。

研究人员发现，宝宝们更爱听这类夸张的“儿语”讲话，而不是典型的成人式讲话。当与音调特色不那么夸张的成人讲话相比，父母说话时音调更高，音域更广时，宝宝们更能集中注意。



【讲解】

文中的baby talk就是“儿语”的意思，其中talk的基本意思是“说话，谈话；谈论”，其后接介词about意为“谈论某事或某人”；后接介词of意为“谈及，谈到”；后接副词over表示“讨论，商量”；后接介词to表示“对…谈话”。

第三段中的exaggerated用作形容词，意为“言过其辞的；夸大的”，如：The exaggerated statistics were published at the inspiration of the government.（那些夸大的统计资料是由政府授意发表的。）
