100多年来，科学界和教育界一直认为年龄对语言学习的结果至关重要，但在生命早期经历的语言的开始和类型是否会影响语言学习能力尚不清楚。在这里，我们表明，在婴儿期接触语言的聋人和听力正常的人在以后的生活中学习一种新语言的表现非常好，而在早期生活中几乎没有语言经验的聋人表现很差，无论早期语言是手语还是口语，以及后来的语言是口语还是手语。这些发现表明，语言学习能力是由大脑早期发育过程中语言经验的开始决定的，与经验的具体形式无关。
For more than 100 years, the scientific and educational communities have thought that age is critical to the outcome of language learning,, but whether the onset and type of language experienced during early life affects the ability to learn language is unknown. Here we show that deaf and hearing individuals exposed to language in infancy perform comparably well in learning a new language later in life, whereas deaf individuals with little language experience in early life perform poorly, regardless of whether the early language was signed or spoken and whether the later language was spoken or signed. These findings show that language-learning ability is determined by the onset of language experience during early brain development, independent of the specific form of the experience.
