Enhanced music sensitivity in 9-month-old bilingual infants
This study explores the influence of bilingualism on the cognitive processing of language and music. Specifically, they investigate how infants learning a non-tone language (a language which does not use tones such as English) perceive linguistic and musical pitch and how bilingualism affects cross-domain pitch perception. Dutch monolingual and bilingual infants of 8–9 months participated in the study. All infants had Dutch as one of the first languages. The other first languages, varying among bilingual families, were not tone or pitch accent languages. To do this, they carried out 2 experiments. The perception of human speech and music is shaped by initial sensitivities at birth and later learning from the environment. Language-wise, infants are born with the ability to discriminate a wide range of native and non-native sound contrasts at birth. In the first year of life, infant sensitivity shifts towards the native language. Just as language, infants show initial sensitivity to m
