The neural basis of non-native speech perception in bilingual children

Abstract:
The goal of the present study is to reveal how the neural mechanisms underlying non-native speech perception change throughout childhood. In a pre-attentive listening fMRI task, English monolingual and Spanish–English bilingual children – divided into groups of younger (6–8 yrs) and older children (9–10 yrs) – were asked to watch a silent movie while several English syllable combinations played through a pair of headphones. Two additional groups of monolingual and bilingual adults were included in the analyses. Our results show that the neural mechanisms supporting speech perception throughout development differ in monolinguals and bilinguals. While monolinguals recruit perceptual areas (i.e., superior temporal gyrus) in early and late childhood to process native speech, bilinguals recruit perceptual areas (i.e., superior temporal gyrus) in early childhood and higher-order executive areas in late childhood (i.e., bilateral middle frontal gyrus and bilateral inferior parietal lobule, among others) to process non-native speech. The findings support the Perceptual Assimilation Model and the Speech Learning Model and suggest that the neural system processes phonological information differently depending on the stage of L2 speech learning.

Sentence interpretation strategies in emergent bilingual children and adultsfnr rid="fn1">fn id="fn1">We dedicate this article to our mentor, Liz Bates, who introduced us to and guided us through the exploration of psycholinguistic processes in bilingual populations. We thank Dan Slobin, and two anonymous reviewers for many constructive comments on previous versions of this paper. We would also like to thank Kain Sosa and Rehana Salahuddin for technical support, and to Paula Bautista for child testing. Finally, we are grateful to the children, their parents, and fami
