The Child Lab is a website where you and your child can participate in research with Yale University.

All of our research is about how children learn and understand the world. We ask our questions to hundreds of children, both at our Yale University lab and online at this website, to learn the most common answers at different ages. Our goal is to understand how children think in general, so there are usually no right or wrong answers.

When children participate in person, they get to choose a prize. If your child participates online, we will e-mail you an Amazon gift card. You can click on the links above for more information or to sign up to receive an e-mail when we have a new study for your child’s age (usually once every few months).
