Nature & Nurture

Dr. Judith Fan is an Assistant Professor of Psychology at Stanford University, where she runs the Cognitive Tools Lab: https://cogtoolslab.github.io/ In this episode, Dr. Fan discusses the concept of reverse engineering the human cognitive toolkit, which involves uncovering the principles and constraints that shape our thinking and the tools we use to support our cognitive processes. She explains that cognitive tools are material artifacts, such as numbers, pictures, and language, that help us think and communicate. Dr. Fan highlights the importance of understanding the mechanisms behind these tools and how they interact with our brains. She explores the use of pictures as a cognitive tool and how they have been used throughout history to encode and communicate knowledge. Dr. Fan also discusses the convergence between artificial neural networks and the human brain in understanding visual inputs, such as faces. She explains that these systems can approximate the behaviors of real neurons and provide insights into how our brains process visual information. Dr. Fan emphasizes the role of education in shaping our cognitive toolkit and the importance of providing learners with multiple modalities for engaging with information. She also discusses the potential of emerging technologies, such as artificial intelligence and machine learning, in supporting rich and generative forms of learning.
