In the World Library of Psychologists series, international experts themselves present career-long collections of what they judge to be their finest pieces - extracts from books, key articles, salient research findings, and their major theoretical and practical contributions. Jonathan St B T Evans is amongst the foremost cognitive psychologists of his generation, having been influential in spearheading developments in the psychological study of reasoning from its very beginnings in the 1970s up to the present day. This volume of self-selected papers recognises Professor Evan's major contribution to the psychological study of thinking and reasoning by bringing together his most influential and important works.

Early selections in the book focus upon experimental studies of reasoning - matching bias in the Wason selection task, belief bias in syllogistic reasoning, and also seminal work on the understanding of conditional statements. The later selections include Evans' work on more general forms of dual process and dual system theory, and his recent account of two minds in one brain. The volume also contains chapters which highlight Evans' contribution to the topic of human rationality, and also his influence on the development of the "new paradigm" in the psychology of reasoning.

The key developments in the psychology of reasoning are paralleled by those in Evans's own intellectual history, and the book will therefore make essential reading for all researchers in the psychology of reasoning, and a wider audience of graduate and upper-level undergraduate students with an interest in reasoning and/or dual process theory.

"This book provides a unique retrospective analysis of the development of modern theories of human reasoning, written by an eminent researcher, from a perspective gained over 40 years as a leading reasoning scientist. A must read for researchers just starting out, and a fascinating read for all students of reason." - Valerie Thompson, University of Saskatchewan, Canada "Jonathan Evans is the leading British investigator of the psychology of reasoning. This book tells the whole story of the development of the field from his days as a young researcher in the late 1960s up to the present day. It is indispensable reading for those new to the field and to the 'old hands'." - Philip Johnson-Laird, University of Princeton, USA "Reader, prepare yourself for a Reasoning Feast in this book. The papers of Jonathan Evans have virtually defined the reasoning field for the last thirty years. From classic papers on the selection task, to some of the best work ever on belief bias, to the latest on dual process theory and the Great Rationality Debate, Evans was there to define the issues for us in ways that were uniquely productive." - Keith E. Stanovich, University of Toronto, Canada
