John R. Anderson

Definition

John R. Anderson is a prominent cognitive psychologist known for his work in cognitive modeling and skill acquisition. He developed the ACT-R (Adaptive Control of Thought-Rational) framework, which aims to simulate human thought processes and understand how knowledge is represented and used in the brain. His research bridges the gap between theoretical cognitive psychology and practical applications, contributing significantly to our understanding of how expertise is developed and how cognitive processes can be modeled.
