Infants in their first year manifest selective patterns of discrimination between languages and between accents of the same language. Prosodic differences are held to be important in whether languages can be discriminated, together with the infant's familiarity with one or both of the accents heard. However, the nature of the prosodic cues that…

During the first year of life, infants begin to have difficulties perceiving non-native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non-segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a…

Argues that knowing how infants process speech is a prerequisite to any definition of linguistic experience and therefore, the discrimination paradigm does not provide a test for the effect of experience on infants' speech discrimination. Outlines conditions to be met in order to conclude an effect of experience. (EKN)

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

It is the contention here that the "prelinguistic" period is an important phase of the language acquisition process. Accordingly the research reported represents an attempt to begin mapping out the types of linguistically relevant information to which a young child attends. Specifically it is hypothesized that young children are…

Examined infants' tendency, from a few days to nine months of age, to prefer infant-directed over adult-directed speech. Results suggest that exaggerated pitch contours that characterize infant-directed speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased…

A review of research leads to the proposal that infants' perception of "fragile" contrasts is lost due to their lack of exposure to particular sounds. Perception of "robust" contrasts is lost around the onset of formal language training due to children's lack of experience with phonologically irrelevant sounds. (Author/CB)
