Steve Sloman is a Professor in the Department of Cognitive & Linguistic Sciences at Brown University. He is a computationally oriented cognitive psychologist who studies how people think. He has studied how people categorize the world and the relation between our names for things and our thoughts about things. He has also studied inductive inference, judgments of probability, decision making, and reasoning. Sloman has recently become interested in how people learn about the way the world works and how we reason causally about it. These interests are reflected in his recent book, Causal Models: How We Think About the World and Its Alternatives, published by Oxford University Press in 2005.
