Welcome to Centre for Child Studies

An adult reading a book to a child

Exploring children's communicative development for over 25 years! 

Since 1995, researchers at the Centre for Child Studies have been exploring how children's language and thinking develops in the early years. Our work has received national and international attention. 

Professor Daniela O'Neill is the founder and director of the Centre. You can find her on twitter at daniela_oneill where she curates information from around the world relevant to children's development and provides up-to-date news on research from the Centre. 

The Language Use Inventory (LUI) is a standardized parent-report measure of children's early language use developed at the Centre and now used by speech-language professionals around the world. Children's early language use (also known as pragmatic language development) is the primary current focus of research at the Centre. Updates about the LUI, directed more specifically speech-language professionals and researchers using the LUI, are also posted to the LUI facebook page and LanguageUseInventory.com

We appreciate all the support of parents, locally and across Canada, who have helped with our research. Each child makes a difference!

This was my daughter’s second time in the study. Bianca seemed to really enjoy spending time with Diane. I think the work being done here is so important for understanding how and why a child develops.

I really enjoyed observing my son’s participation. The researcher put us all at ease and did a great job. Everything about the process has been enjoyable for us.

We love coming to the centre. We’ve been involved since our child was a baby. We’re always very eager and happy to come and help out.
