| Abstract: | It is well established that newborns prefer some sounds over others. It is widely believed that these preferences reflect past experience, either prenatally or in the immediate postnatal environment. However, it is also possible that structural factors are involved. The frequency of occurrence of different sounds in the languages of the world may provide evidence of such structural factors. If structural factors are important, and if frequency of occurrence of sounds in the world’s languages reflects structural factors, then we might expect newborn preference for sounds to reflect their frequency across languages. In this study, newborns were presented with two cv pairs consisting of a trilled /r/ and a bunched /r/ followed by the vowel //. The newborns were either of English‐speaking or Spanish‐speaking origin. The bunched /r/ occurs in American English and is not frequent in the languages of the world. It does not occur in Spanish. The trilled /r/ occurs in Spanish and is a frequent consonant in the languages of the world. It does not occur in American English. Results showed that newborns of both linguistic backgrounds preferred to listen to the trilled /r/. It is hypothesized that the frequency of occurrence of a sound in the languages of the world may reflect structurally based ease of production and ease of perception, the latter leading to the newborn preference. |
