Although prior research has established that perceptual narrowing reflects the influence of experience on the development of face and speech processing, it is unclear whether narrowing in the two domains is related. A within-participant design (N = 72) was used to investigate discrimination of own- and other-race faces and native and non-native speech sounds in 3-, 6-, 9-, and 12-month-old infants. For face and speech discrimination, whereas 3-month-olds discriminated own-race faces and native speech sounds as well as other-race faces and non-native speech sounds, older infants discriminated only own-race faces and native speech sounds. Narrowing in face and narrowing in speech were not correlated at 6 months, negatively correlated at 9 months, and positively correlated at 12 months. The findings reveal dynamic developmental changes in the relation between modalities during the first year of life.
尽管先前的研究已经证实，知觉窄化反映了经验对面部和语音处理发展的影响，但尚不清楚这两个领域的窄化是否相关。本研究采用被试内设计（N = 72），对3个月、6个月、9个月和12个月大的婴儿进行了本族与他族面孔以及母语与非母语语音辨别能力的测试。在面孔和语音辨别方面，3个月大的婴儿能够辨别本族面孔和母语语音，也能辨别他族面孔和非母语语音，而年龄较大的婴儿只能辨别本族面孔和母语语音。6个月时，面孔窄化和语音窄化不相关；9个月时，二者呈负相关；12个月时，二者呈正相关。研究结果揭示了生命第一年中不同感知觉领域之间关系的动态发展变化。
