'This is the first book putting forward the main scientific results of an intriguing and promising new research domain called 'quantum cognition'. In this emergent field, the mathematical structure of quantum theory is employed to model essential aspects of human cognition impossible to be modelled properly within classical approaches. The authors are both engaged intensively in quantum cognition and [have written] a high-quality and well-understandable treatise showing how this new approach carries the potential of a real breakthrough, with deep implications for how cognition will be looked upon in the decades to come. The approach may also signify a thorough new opening to the old problem of artificial intelligence and the structuring of semantics.' Diederik Aerts, Brussels Free University

Much of our understanding of human thinking is based on probabilistic models. This innovative book by Jerome R. Busemeyer and Peter D. Bruza argues that, actually, the underlying mathematical structures from quantum theory provide a much better account of human thinking than traditional models. They introduce the foundations for modeling probabilistic-dynamic systems using two aspects of quantum theory. The first, 'contextuality', is a way to understand interference effects found with inferences and decisions under conditions of uncertainty. The second, 'quantum entanglement', allows cognitive phenomena to be modeled in non-reductionist ways. Employing these principles drawn from quantum theory allows us to view human cognition and decision in a totally new light. Introducing the basic principles in an easy-to-follow way, this book does not assume a physics background or a quantum brain and comes complete with a tutorial and fully worked-out applications in important areas of cognition and decision.
