the online child lab

A project of the MIT Early Childhood Cognition Lab

Participate in a Study

Bringing science home

Here at MIT's Early Childhood Cognition Lab, we're trying a new approach in developmental psychology: bringing the experiments to you.

Help us understand how your child thinks

Our online studies are quick and fun, and let you as a parent contribute to our collective understanding of the fascinating phenomenon of children's learning. In some experiments you'll step into the role of a researcher, asking your child questions or controlling the experiment based on what he or she does.

Participate whenever and wherever

Log in or create an account at the top right to get started! You can participate in studies from home by doing an online activity with your child that is videotaped via your webcam.

Data collection is complete for the Lookit studies "Baby Euclid," "Mind and Manners", "Flurps and Zazzes," and "Words and Objects" (but stay tuned for follow-ups!). We're still looking families with babies to participate in "Look and Listen," "Your Baby the Physicist," and "Baby Laughter Games."

It's not just an MIT lab! The first studies run by outside researchers (not at MIT or directly collaborating) are live on Lookit: "Words and Objects" (from Bria Long and Mike Frank, Stanford) and "Baby Laughter Games" (from Caspar Addyman, Goldsmiths London).

Our two papers describing online replications of classic developmental studies on a prototype of the Lookit system are now available in the first issue of Open Mind, a new open-access journal from MIT Press! Thank you so much to all of our early participants who made this work possible.

We're back up and running! If you had an account on the old site, you should have received an email letting you know how to access your new account. We're getting started by piloting a study about babies' intuitive understanding of physics!

Lookit is taking a break while our partners at the Center for Open Science work on re-engineering the site so it's easier for both parents and researchers to use. We're looking forward to re-opening the login system and starting up some new studies early this fall! Please contact lookit@mit.edu with any questions.

We've finished collecting data for replications of three classic studies, looking at infants' and children's understanding of probability, language, and reliability. The results will be featured here as soon as they're published!
