Bergelson Lab

Harvard University's Laboratory for Developmental Studies

The Bergelson Lab (aka BLAB ) is a part of the Laboratory for Developmental Studies group within the Department of Psychology at Harvard University. We are located on the 11th floor at William James Hall.

We study infant word learning, in particular how infants’ early linguistic and environmental input plays a role in their learning. We focus on understanding how babies learn words from the visual, social, and linguistic world around them.

The BLAB moved to Harvard from Duke University in 2023. And it moved to Duke in 2016 from the University of Rochester, where it finished data collection in July 2016 for a longitudinal study called SEEDLingS ( S tudy of E nvironmental E ffects on D eveloping Ling uistic S kills). You can read more about that work here .
