Welcome to the Johns Hopkins University Lab for Child Development!

Housed in the Johns Hopkins University Department of Psychological and Brain Sciences, we investigate how infants and young children understand the world around them.

Our studies, featured in media outlets including the New York Times, NPR, and Time Magazine, ask questions such as: What do babies remember about hidden objects?  What are the developmental foundations of mathematical thinking?  Are children logical?  And how does surprise affect infants’ learning?

Do you have a child scientist on your hands?  We are seeking children from 0 to 10 years to come help us learn about children’s thinking!  Our studies involve a one-time visit that includes playing simple games, or showing babies specially designed puppet shows, and measuring how children respond. We would love for your child to participate!  We have both in-person and online studies, and your child will receive either a $5 Amazon gift card or a small prize as a token of our appreciation!  To find out more, visit our Our Studies page and sign up via our easy Participant Portal.
