提出了一系列实验来研究这种方式
婴幼儿对鼻音和自然发音的感知是
以及与复杂的时间和频率匹配的非语音刺激
以言语表达的关系。歧视和分类数据将
从6个月到12个月大的婴儿使用操作式翻头获得
程序。区分、分类和标注数据将
从2到4岁的儿童使用两个可选的指点
程序。对婴儿的研究将集中在对外国人的歧视上
语音对比、交易关系、停辅音位置的分类
CV音节的发音类别和元音类别的提取
语音特征。对幼儿的研究将集中在
外国言语对比的歧视、歧视与标签
元音、元音规范化和减少、语境影响、交易

英文摘要
A series of experiments are proposed for investigating the manner in which
infants and young children perceive snythetic and natural speech sounds as
well as nonspeech stimuli that match the complex temporal and frequency
relations present in speech. Discrimination and categorization data will
be obtained from 6- to 12-months-old infants using an operant headturning
procedure. Discrimination, categorization, and labeling data will be
obtained from 2- to 4-year-olds using a two-alternative pointing
procedure. Studies of infants will focus on the discrimination of foreign
speech contrasts, trading relations, categorization of stop consonant place
of articulation and vowel category in CV syllables, and the extraction of
phonetic features. Studies of young children will focus on the
discrimination of foreign speech contrasts, the discrimination and labeling
of vowels, vowel normalization and reduction, context effects, trading
relations, feature extraction, and the discrimination and labeling of place
of articulation in stops, VOT, and TOT. In addition to these studies of
speech perception, experiments with 6- to 12-months-olds will address
several aspects of developmental psychoacoustics, including thresholds for
high frequency tones, frequency discrimination, discrimination of frequency
modulation, and psychophysical tuning curves. These psychoacoustic studies
will not only establish norms for this age range but also uncover any
sensory constraints on speech discrimination. The overall goal of this
program of research is to evaluate the mechanisms underlying speech
perception in infancy and early childhood. The role of early linguistic
experience, particularly in the early stages of language production, will
be examined, as well as the onset age for a phonetic mode of analysis.
