The Headturn Preference Procedure (HPP) is widely used in infant research. Previous studies have shown that speech perception measures obtained with HPP are related to later language skills which may make them a potential instrument for an early detection of developmental language risks. The present study assessed the reliability and stability of…

One hypothesis to explain perceptual narrowing in speech perception is the distributional learning account. This account claims that both infants and adults are able to infer the number of phonemic categories through observations of frequency distributions of individual phones in their speech input (Maye, Werker, & Gerken, 2002). Although the…

The literature reports some contradictory results on the degree of phonological specificity of infants' early lexical representations in the Romance language, French, and Germanic languages. It is not clear whether these discrepancies are because of differences in method, in language characteristics, or in participants' age. In this study, we…

Examined the possibility that auditory stimuli with properties of adult-to-infant speech are more detectable in a noisy ambient environment than ones that resemble adult-to-adult speech. Findings suggests that properties that characterize adult-to-infant speech may compensate for young infants' low-frequency deficits and therefore facilitate the…

This study treats the child's vocal and rhythmic development immediately subsequent to birth and forward, and shows how this development relates to musical learning. (Author)
