视觉、听觉和多感觉领域的知觉狭窄起源于婴儿期。本研究表明，实验诱导的经验可以逆转知觉窄化对婴儿异种族面孔视觉再认记忆的影响。在测试开始时，无法区分新面孔和熟悉的亚洲面孔的8至10个月大的白人婴儿在实验条件下对亚洲女性面孔进行了简短的日常体验，并在控制条件下对白人女性面孔进行了简单的日常体验。在三周结束时，只有每天与亚洲女性接触的婴儿才能对新的亚洲女性和男性面孔进行随机识别。此外，实验条件下的婴儿在学习新的亚洲女性方面比对照条件下的婴儿表现出更高的效率。因此，具有新刺激类别的视觉体验可以通过改善刺激识别和编码来扭转婴儿期知觉变窄的影响。
Perceptual narrowing in the visual, auditory, and multisensory domains has its developmental origins in infancy. The present study shows that experimentally induced experience can reverse the effects of perceptual narrowing on infants’ visual recognition memory of other-race faces. Caucasian 8- to 10-month-olds who could not discriminate between novel and familiarized Asian faces at the beginning of testing were given brief daily experience with Asian female faces in the experimental condition and Caucasian female faces in the control condition. At the end of three weeks, only infants who received daily experience with Asian females showed above-chance recognition of novel Asian female and male faces. Further, infants in the experimental condition showed greater efficiency in learning novel Asian females compared to infants in the control condition. Thus, visual experience with a novel stimulus category can reverse the effects of perceptual narrowing in infancy via improved stimulus recognition and encoding.
