This news release from the UCLA Newsroom website features a large study that Prof. Mateu collaborated in and was recently published in the Advances in Methods and Practices in Psychological Science Journal.
Among other questions, in this paper, Mateu and colleagues addressed a concern that many parents have —whether bilingualism causes language difficulties or delays. In this multi-lab study, hundreds of infants between 6 and 15 months old were tested from across the globe and it was found that bilingual infants show the same preference for “baby talk” and to the same extent as monolingual infants, highlighting the similarities in attentional and learning mechanisms across these two populations.
