为了确定习得的年龄如何影响第二语言语音的感知，对6岁之前（早期双语者）或14岁之后（晚期双语者）和单语美国英语使用者（单语者）学习流利英语的母语墨西哥-西班牙语听众进行了噪音中的语音感知（SPIN）测试。结果表明，噪声水平的语音是可理解的显着更高，从音乐会的好处是显着更大的单语者和早期双语者比后期双语者。这些发现表明，在早期学习第二语言对于获得有效的高水平处理是重要的，至少在噪音存在的情况下。
To determine how age of acquisition influences perception of second-language speech, the Speech Perception in Noise (SPIN) test was administered to native Mexican-Spanish-speaking listeners who learned fluent English before age 6 (early bilinguals) or after age 14 (late bilinguals) and monolingual American-English speakers (monolinguals). Results show that the levels of noise at which the speech was intelligible were significantly higher and the benefit from concert was significantly greater for monolinguals and early bilinguals than for late bilinguals. These findings indicate that learning a second language at an early age is important for the acquisition of efficient high-level processing of it, at least in the presence of noise.
