But bilinguals, there's evidence showing that they're not relying on mutual exclusivity as much as monolinguals.

然而，有证据显示双语儿童不像单语儿童一样依赖互斥性原则。

We know that monolinguals, around 18 months, they use mutual exclusivity, which is a strategy in which they are mapping a novel word to a novel object.

我们知道，单语儿童在大约 18 个月左右时，会使用“互斥性原则”来将新单词与新物体建立关联。
