Krista Byers-Heinlein

Concordia University

 

Dr. Krista Byers-Heinlein is a Full Professor in the Department of Psychology at Concordia University, where she holds the Concordia University Research Chair in Bilingualism and Open Science and directs the Concordia Infant Research Lab. Her research focuses on infants and children who grow up in bilingual environments. She has made notable discoveries about how very young bilinguals discriminate and differentiate their two languages, how children are able to learn words in two languages to build their vocabularies, and how parents interact with their bilingual children to support their development. She is also active in efforts to improve psychological science, working to improve methods, increase transparency, build large-scale collaborations in the field, and promote equity and inclusion for under-represented groups. Dr. Byers-Heinlein is a founding member of the governing board of the ManyBabies Consortium, which spans 200+ labs across 40+ countries, which has fundamentally changed how developmental research is conducted globally.

Dr. Byers-Heinlein has authored more than 80 peer-reviewed articles in journals such as Psychological Science, Child Development, Developmental Science, and the Proceedings of the National Academy of Sciences and is co-author of the book, The listening bilingual: Speech perception, comprehension, and bilingualism. Her research has been supported by over 3.7 million dollars CAD in direct costs from granting agencies including from the Social Sciences and Humanities Research Council of Canada, Natural Sciences and Engineering Research Council of Canada, les Fonds de recherche de Quebec, and National Institutes of Health. Her research is often featured in print and broadcast media, including Global TV, CBC Radio, Psychology Today, PBS, the Globe and Mail, and the New York Times. Her work has been recognized by numerous awards, including most recently the 2025 Quebec “Rising Star” prize for leadership and scientific excellence.

 


Abstract

What Bilingual Babies Reveal About How All Children Learn

Bilingual children show remarkable variation—some become fluent in multiple languages while others struggle, despite seemingly similar circumstances. This puzzle illuminates a fundamental challenge in understanding how all children learn. Traditional approaches focus on isolated factors that correlate with developmental outcomes, ranging from age and exposure to family background and culture. Yet these correlations mask the underlying mechanisms that actually drive development. Here, I argue that systems thinking that considers dynamic interactions across system levels is crucial for understanding underlying mechanisms of learning and development. Drawing from experimental, parent-report, and sociolinguistic research on language acquisition in bilingual infants, I show how development emerges from the interplay between maturational factors and experience, and how developmental outcomes depend on alignment across individual, family, and societal levels. What bilingual babies teach us extends far beyond language: successful development in any domain requires understanding the complex web of interacting forces that shape children’s minds.

She is a recipient of the Troland Award from the National Academy of Sciences, the Boyd McCandless Early Career Award from APA, and a James S. McDonnell Foundation Scholar Award. She feels fortunate to have been mentored by outstanding and inspiring scientists, and to have been surrounded by brilliant students and colleagues throughout her career.


Abstract

The cradle of curiosity

Curiosity underpins the greatest of human achievements, from exploring the reaches of our solar system to discovering the structure of our own minds. Where does this drive come from? Here I suggest that far from being reliant on language and sophisticated metacognitive skills, curiosity is present from our earliest days. In support of this claim, I discuss work showing that preverbal infants not only experience curiosity but harness it: when babies’ predictions fail to accord with their observations, they look longer, learn more, and produce exploratory behaviors. Critically, their exploration is guided by a desire to explain —long before they have the words to describe what they see, babies seek to understand why things happen as they do. In this sense, the curiosity that emerges in infancy lays the foundation for a lifetime of discovery.

Bilingual/Multilingual Development

 

Viridiana Benitez

Viridiana Benitez

Arizona State University

Viridiana Benitez is an Assistant Professor at Arizona State University, where she directs the Learning & Development Lab and co-founded the Early Childhood Cognition Research Group. Her research examines how cognition, context, and experience shape language learning across development. To achieve this, Benitez works with infants, children, and adults from monolingual and multilingual backgrounds. With this research, Benitez aims to identify the factors that promote language learning in children growing up across diverse learning environments. As a bilingual first generation student from an immigrant family, Benitez is also dedicated to expanding access to psychological science for students, families, and communities.

Bio to come

Drew Weatherhead

Drew Weatherhead

Dalhousie University

Dr. Drew Weatherhead is an Associate Professor in the Department of Psychology & Neuroscience at Dalhousie University. Her research investigates the mechanisms of early language acquisition, with a particular focus on sociolinguistic development in infancy and early childhood. Using methods such as eye-tracking and functional near-infrared spectroscopy (fNIRS), she examines how children process accented speech and how social factors—such as speaker race—influence language perception and learning. Her recent work explores how bilingual experience and social context shape early speech processing and lexical development.

Adriana Weisleder

Adriana Weisleder

Northwestern University

Adriana Weisleder is an assistant professor in Communication Sciences and Disorders at Northwestern University. Her research investigates early language development in young children from a range of sociocultural backgrounds, with a focus on multilingual learners. She conducts observational and experimental work to investigate both the learning mechanisms and contexts that support language development. An important goal of this work is to contribute to building a more robust evidence base for understanding variability in language development across diverse environments. Her work has been funded by the National Institutes of Health, Academic Pediatric Association, and Russell Sage Foundation, among others.

Children’s scientific reasoning
