Forty-four sequential bilingual children aged fifteen underwent assessments of speech-in-noise perception, first and second language vocabulary and auditory working memory (forward digit span). In order to investigate the signal driven processes might affect bilinguals’ “spatial release from masking” (SRM) a listening in spatialized noise paradigm was adapted for the bilingual context. A simple number and colour identification task presented in English and Swedish, and the talker was masked adaptively by speech-shaped noise and eight-talker babble under two spatialized conditions in simulated room acoustics; targets and maskers were either collocated at zero degrees azimuth or spatially separated at ninety degrees azimuth to either side. The resulting language and noise conditions were contrasted with existing research on bilingual adults and native-language speaking children, extending findings to a younger sample of sequential bilingual children. The results indicating a significant relationship between cognitive ability and second-language speech reception threshold.
