Understanding the Role of Scientific Models

Episode 136

I spoke with Judy Fan about:

* Our use of physical artifacts for sensemaking

* Why cognitive tools can be a double-edged sword

* Her approach to scientific inquiry and how that approach has developed

Enjoy—and let me know what you think!

Judy is Assistant Professor of Psychology at Stanford and director of the Cognitive Tools Lab. Her 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.
