研究了6-8月龄和10-12月龄英语学习婴儿对两个德语元音对比的辨别。年龄较小的婴儿比年龄较大的婴儿能够更好地区分非母语对比，但6-8个月的表现低于非母语辅音对比的水平。第二个使用习惯化观察程序的实验表明，4个月大的婴儿能够区分德语元音对比，但6个月大的婴儿却不能。这一发现与之前的辅音研究一致，揭示了在生命的第一年，从通用语言向特定语言模式的转变。然而，元音的这种转变在发育过程中开始得比辅音早。
Discrimination of 2 German vowel contrasts was examined in English-learning infants of 6-8 and 10-12 months of age using a head tum procedure. The younger infants were better able than the older infants to discriminate the nonnative contrasts, but performance at 6-8 months was below levels that have been reported for nonnative consonant contrasts. A 2nd experiment using a habituation looking procedure showed that 4-month-old infants discriminated both German vowel contrasts, but the 6-month-olds could not. The findings are consistent with previous consonant work, revealing a shift from a language-general toward a language-specific pattern during the 1st year of life. However, that shift begins earlier in development for vowels than for consonants.
