Lance Rips describes a unified theory of natural deductive reasoning and fashions a working model of deduction, with strong experimental support, that is capable of playing a central role in mental life.

Originally published in 1982, this was an extensive and up-to-date review of research into the psychology of deductive reasoning, Jonathan Evans presents an alternative theoretical framework to the rationalist approach which had dominated much of the published work in this field at the time. The review falls into three sections. The first is concerned with elementary reasoning tasks, in which response latency is the prime measure of interest. The second and third sections are concerned with syllogistic and propositional reasoning respectively, in which interest has focused on the explanation of frequently observed logical errors. In an extended discussion it is argued that reasoning processes are content specific, and give little indication of the operation of any underlying system of logical competence. Finally, a dual process theory of reasoning, with broad implications and connections with other fields of psychology, is elaborated and assessed in the light of recent evidence.

This book brings together both theoretical and empirical research directed toward the role of strategies in deductive reasoning. It offers the first systematic attempt to discuss the role of strategies for deductive reasoning. The empirical chapters correspond well with the main issues in the study of deduction, namely propositional reasoning, spatial reasoning, and syllogistic reasoning. In addition, several chapters present a theoretical analysis of deduction, related to the concept strategy. The book also presents data about the role of strategies for statistical and social reasoning. This book will be of interest to researchers and students of cognitive psychology. It will also be of value to people working in Artificial Intelligence, because it highlights results on how humans use strategies while tackling deductive puzzles.

At the core of the "Psychology of Reasoning" is a vigorous discussion that incorporates various illustrations--some of them humorous, all of them fascinating--of the use of reason under a wide variety of different conditions. Particular emphasis is placed on the difficulties involved in dealing with negatively marked information that must be combined and used with other information for reaching conclusions. Thorough treatment is given as well to the search for plausible contexts that will render anomalous or ambiguous statements "sensible."

How do we define thinking? Is it simply memory, perception and motor activity or perhaps something more complex such as reasoning and decision making? This book argues that thinking is an intricate mix of all these things and a very specific coordination of cognitive resources. Divided into three key sections, there are chapters on the organization of human thought, general reasoning and thinking and behavioural outcomes of thinking. These three overarching themes provide a broad theoretical framework with which to explore wider issues in cognition and cognitive psychology and there are chapters on motivation and language plus a strong focus on problem solving, reasoning and decision making – all of which are central to a solid understanding of this field. The book also explores the cognitive processes behind perception and memory, how we might differentiate expertise from skilled, competent performance and the interaction between language, culture and thought.

Our extraordinary capacity to reason and solve problems sets us aside from other animals, but our evolved thinking processes also leave us susceptible to bias and error. The study of thinking and reasoning goes back to Aristotle, and was one of the first topics to be studied when psychology separated from philosophy. In this Very Short Introduction Jonathan Evans explores cognitive psychological approaches to understanding the nature of thinking and reasoning, problem solving, and decision making. He shows how our problem solving capabilities are hugely dependent on also having the imagination to ask the right questions, and the ability to see things from a completely new perspective. Beginning by considering the approaches of the behaviorists and the Gestalt psychologists, he moves on to modern explorations of thinking, including hypothetical thinking, conditionals, deduction, rationality, and intuition. Covering the role of past learning, IQ, and cognitive biases, Evans also discusses the idea that there may be two different ways of thinking, arising from our evolutionary history.
