Summary: Sally
Three experiments were conducted to test whether native language recognition hypothesis (N hypothesis), general language discrimination hypothesis (G hypothesis), or rhythm-based language discrimination hypothesis (R hypothesis) offers a better prediction of how infants discriminate utterances from different languages. Low-passed filtered sentences were used to test 5-day old newborn infants. In the first two experiments, infants discriminated between a stress-timed and a mora-timed language, but failed to do so between two stress-timed languages. In Experiment 3, infants were tested with combinations of two languages from stress-timed and syllable-timed classes. Results showed that newborns could distinguish languages of different rhythmic classes but not for those belonging to the same class, which implied that newborns used rhythmic information to classify languages and the R hypothesis was supported.
