虽然有许多关于言语感知发展的理论，但有犹太人关于人类新生儿言语感知的数据。本文探讨了新生儿的方式，以一组刺激，定义一个表面的成人元音空间。实验我使用了优先听力/习惯化范式，以发现新生儿如何划分元音空间。结果表明，有高偏好区两侧的低偏好区。高偏好的区域大致对应于成年人容易识别元音的区域。实验2提出了新生儿的元音对实验1中发现的区域。每对中的一个成员是来自一个区域的最优选的元音，另一个成员是来自低偏好的相邻区域的最不优选的元音。实验2中保留了偏好模式。然而，实验1和2的比较表明，在实验1中已经发生了习惯化。实验三采用熟悉化偏好范式，验证了实验一中的习惯化是由于分类过程的假设。研究结果支持了这一假设，即新生儿分类的元音空间在一个成年人一样的方式，与元音被认为是相对好或差的元音类别的例子。
While there are many theories of the development of speech perception, there are Jew data on speech perception in human newborns. This paper examines the manner in which newborns responded to a set of stimuli that define one surface of the adult vowel space. Experiment I used a preferential listening/habituation paradigm to discover how newborns divide that vowel space. Results indicated that there were zones of high preference flanked by zones of low preference. The zones of high preference approximately corresponded to areas where adults readily identify vowels. Experiment 2 presented newborns with pairs of vowels from the zones found in Experiment 1. One member of each pair was the most preferred vowel from a zone, and the other member was the least preferred vowel from the adjacent zone of low preference. The pattern of preference was preserved in Experiment 2. However, a comparison of Experiments I and 2 indicated that habituation had occurred in Experiment 1. Experiment 3 tested the hypothesis that the habituation seen in Experiment I was due to processes of categorization, by using a familiarization preference paradigm. The results supported the hypothesis that newborns categorized the vowel space in an adult-like manner, with vowels perceived as relatively good or poor exemplars of a vowel category.
