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.
