Children can take part in a fun study about language and thought with the U-M's Conceptual Development Lab. For more than 20 years, we have been conducting research on children’s language and thought. 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 4 and 10. Learn more here. This lab is directed by Dr. Susan Gelman and is located in the University of Michigan Psychology Department.
