Welcome to the Conceptual Development Lab!


Due to a technical glitch, it is possible that if you signed up to participate in our research between March 2018 and October 2019 through the link on our website, your response may not have been recorded. If you signed up during this time and are still interested in participating, please resubmit your response. We apologize for any inconvenience and appreciate your support!


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.
