与结构相似的非语音声音相比，婴儿是否将语音视为一种特殊信号呢？我们向2至7个月大的婴儿呈现无意义的语音声音和复杂的非语音类似物。非语音类似物保留了语音信号的许多频谱和时间特性，包括已知对幼儿很显著的音高轮廓信息，因此为语音的潜在听觉偏向提供了一种严格的测试。我们的结果表明，年仅2个月的婴儿听语音声音的时间更长。这种听觉选择性表明，早期起作用的偏向引导婴儿关注语音，使语音相对于其他声音具有特殊地位。
Do young infants treat speech as a special signal, compared with structurally similar non-speech sounds? We presented 2- to 7-month-old infants with nonsense speech sounds and complex non-speech analogues. The non-speech analogues retain many of the spectral and temporal properties of the speech signal, including the pitch contour information which is known to be salient to young listeners, and thus provide a stringent test for a potential listening bias for speech. Our results show that infants as young as 2 months of age listened longer to speech sounds. This listening selectivity indicates that early-functioning biases direct infants' attention to speech, granting speech a special status in relation to other sounds.
