Our research investigates how infants from different language backgrounds, both monolingual and bilingual, grow and learn about their language(s).

Our team consists of Dr. Krista Byers-Heinlein and a group of dedicated students and research assistants. On our website you can meet the research team, learn about our research projects, download our publications, and find out how to participate in our studies or join our team. 


Our research could not happen without parents like you and we are truly thankful for the support and enthusiasm of all the parents and children who participate in our studies.



We are inviting parents with children (newborns to 5-year-olds) from English-speaking, French-speaking, bilingual, and multilingual backgrounds to participate in one of our studies. If you are interested in participating or would like more information, please contact us:


You can also get in touch with us via email at or by telephone at 514-848-2424 ext. 5831.

frequently asked questions

How many times do I have to participate?

Our studies require you to come to our laboratory for one visit only. Once you have participated, if you wish, we can contact you if we have any other studies that your child could participate in.

How long does a visit normally take?

Your baby’s participation lasts 5-10 minutes, and you will be with your baby the whole time. We will also ask you to complete some questionnaires about your baby’s background and knowledge. In total, your visit will last 1-1.5 hour.

When do you run the studies?

We are here all year long, every day of the week from 9:00 a.m. to 5:00 p.m. If you are interested, contact us and we will schedule an appointment at a time that is most convenient for you.

Can I bring my other children to the lab?

Yes. We have well-trained research assistants on staff to babysit during studies. Our lab is equipped with a child-friendly waiting room and playroom filled with toys, games, and other activities.

What are the benefits of participating?

You will get to learn more about how babies learn their languages and how researchers are able to discover what babies know even before they can talk.

As a thank you for your participation, we offer a baby-tee or small gift. Your baby will also earn an Honorary Bachelor’s degree, and can go on to earn a Master’s or higher if you choose to participate in future studies. We provide free parking or a transit pass to make your visit as easy as possible.

Will I learn whether my child is developing normally?

Our studies look at the performance of a large group of children. We are interested in the average performance of children at different ages and under different conditions (e.g. monolingual, bilingual). It is therefore impossible for us to provide you with an individual evaluation for your child. We do, however, explain the goals of our studies and what we expect to find. We also prepare a newsletter for parents which summarizes our findings once a study is completed. If you are concerned about your child’s development, we encourage you to speak with your doctor.
