The Cognitive Tools Lab is directed by Prof. Judith Fan and located in the Stanford Department of Psychology.

Our lab employs converging approaches from cognitive science, computational neuroscience, and artificial intelligence to reverse engineer the human cognitive toolkit, especially how people use physical representations of thought — such as sketches and prototypes — to learn, communicate, and solve problems.

One of our central goals is to connect fundamental questions about human cognition to the project of equipping more people with the cognitive skills that will help them throughout their lives. Here is a talk Judy Fan gave at the 2025 TEDAI conference related to this mission, entitled “How the human mind will coevolve with AI”.
