Research








Research in our lab is approved by the Psychology/Sociology Research Ethics Board. We are grateful for funding from the TransAtlantic Platform Digging into Data Challenge and SSHRC (Social Sciences and Humanities Research Council), as well as internal funding from the University of Manitoba.

Preference Studies

How are infants' preferences for the special properties of child-directed speech different in different (or the same) cultures and languages? (4-15 month olds)

We speak very differently to babies than we do to other adults — but this style of speaking varies across cultures and languages. In a large scale study involving several dozen laboratories around the world, we are comparing infants' preference for this form of speech. This study is also allowing us to study and make improvements on the methods we use.

How does bilingual language experience affect infants' perception of vowel sounds? (5, 8, and 12 month olds)

Different languages have different boundaries between vowel sounds. We are comparing how bilingual French-English, bilingual German-English and English monolingual infants hear vowel sounds.

Recording Studies

What are the language environments of infants born to young mothers? (0-24 month olds)

Young mothers face many challenges in providing high quality developmental environments for their infants. We are currently examining recordings of young mothers' everyday interactions with their infants. Our findings will help us know how best to support these mothers.
