The Markman Lab

Parents and guardians of children

Help us understand how children think! We value families' involvement in science, and offer research activities for children of many ages. Participating families receive a $5 gift card as a token of appreciation for contributing to our science.

Our research activities are currently online, and your child can participate from the comfort of your own home. All you need is internet access and a computer or tablet with a camera or a webcam. Our activities are short (5-15 minutes), fun, and age-appropriate experiences for children, conducted by trained researchers. We typically read children stories and ask them questions in English. Parents and guardians may be present during the activity if they wish. We just ask that you allow the child to respond however they like, since we want to know what children think!

See our Projects page for some current activities we offer.

Synchronous participation with us over Zoom

To sign your child up for synchronous participation, where we will schedule a time to meet over Zoom, please take 1-2 minutes to fill out the Stanford Developmental Psychology research participation contact form above. We'll contact you by email when we have a research activity available for your child.

If you have questions about participating in online research, contact the Stanford Developmental Psychology online research team at We'll help answer your questions so you and your child can start doing science with us!

Asynchronous participation with us

We also offer asynchronous participation for some of our studies, so you and your child can participate anytime at your own convenience. You can sign up to participate in our studies on Lookit.

In-person research partnerships and locations

(suspended until further notice due to COVID-19):


We periodically run studies for adults online on Prolific and Amazon Mechanical Turk (MTurk). Our studies are generally 5-20 minute surveys for US-based adults that pay around $10/hour.

If we have studies available on Prolific or MTurk, you can find them by searching Prolific for Markman Lab or searching MTurk for Markman Lab. You can see reviews by participants of our MTurk studies on our Turkopticon review page.
