Welcome to the Conceptual Development Lab!


In light of the spread of COVID-19, the University of Michigan has asked that all in-person research activities, including our studies at the Conceptual Development Lab, be suspended. However, we are very excited to announce that we are now holding VIRTUAL research sessions!

If you are interested in signing up to participate in ONLINE, VIRTUAL research, fill out this form and our team will be in contact with you shortly!



The Conceptual Development Lab is directed by Dr. Susan Gelman and is located in the Psychology Department at the University of Michigan.

Thank you very much for visiting our website. For over 20 years, we have been conducting research on children’s language and thought at the University of Michigan. Our projects explore cognitive development, category formation and use, causal reasoning, and relationships between language and thought. Most of our studies focus on children between the ages of 2 and 10, and are conducted either in our home-like laboratory setting or in area preschools and schools. If you are a parent who is interested in participating, please check out the Parents section for information about our current studies.
