An aberrant belief is extreme or unusual in nature. In the most serious cases these beliefs cause emotional distress in those who hold them, and typify the core symptoms of psychological disorders. Each of the chapters in this volume seeks to examine the role that biases in reasoning can play in the formation of aberrant beliefs. The chapters consider several conjectures about the role of reasoning in aberrant belief, including the role of the jumping to conclusion bias in delusional beliefs, the probabilistic bias in paranormal beliefs, the role of danger confirming reasoning in phobias, and the controversial notion that people with schizophrenia do not succumb to specific forms of reasoning bias. There are also chapters evaluating different theoretical perspectives, and suggestions for future research. Aberrant Beliefs and Reasoning is the first volume presenting an overview of contemporary research in this growing subject area. It will be essential reading for academics and students in the fields of human reasoning, cognitive psychology and philosophy, and will also be of great interest to clinicians and psychiatrists.

Dual Process Theory 2.0 provides a comprehensive overview of the new directions in which dual process research is heading. Human thinking is often characterized as an interplay between intuition and deliberation and this two-headed, dual process view of human thinking has been very influential in the cognitive sciences and popular media. However, despite the popularity of the dual process framework it faces multiple challenges. Recent advances indicate that there is a strong need to re-think some of the fundamental assumptions of the original dual process model. With chapters written by leading scholars who have been actively involved in the development of an upgraded ‘Dual Process Theory 2.0’, this edited volume presents an accessible overview of the latest empirical findings and theoretical ideas.. With cutting edge insights on the interaction between intuition and deliberation, Dual Process Theory 2.0 should be of interest to psychologists, philosophers, and economists who are using dual process models.

Moral Inferences is the first volume to thoroughly explore the relationship between morality and reasoning. Drawing on the expertise of world-leading researchers, this text provides ground-breaking insight into the importance of studying these distinct fields together. The volume integrates the latest research into morality with current theories in reasoning to consider the prominent role reasoning plays in everyday moral judgements. Featuring contributions on topics such as moral arguments, causal models, and dual process theory, this text provides a new perspectives on previous studies, encouraging researchers to adopt a more integrated approach in the future. Moral Inferences will be essential reading for students and researchers of moral psychology, specifically those interested in reasoning, rationality and decision-making.

David E. Over is a leading cognitive scientist and, with his firm grounding in philosophical logic, he also exerts a powerful influence on the psychology of reasoning. He is responsible for not only a large body of empirical work and accompanying theory, but for advancing a major shift in thinking about reasoning, commonly known as the ‘new paradigm’ in the psychology of human reasoning. Over’s signature mix of philosophical logic and experimental psychology has inspired generations of researchers, psychologists, and philosophers alike over more than a quarter of a century. The chapters in this volume, written by a leading group of contributors including a number who helped shape the psychology of reasoning as we know it today, each take their starting point from the key themes of Over’s ground-breaking work. The essays in this collection explore a wide range of central topics—such as rationality, bias, dual processes, and dual systems—as well as contemporary psychological and philosophical theories of conditionals. It concludes with an engaging new chapter, authored by David E. Over himself, which details and analyses the new paradigm psychology of reasoning. This book is therefore important reading for scholars, researchers, and advanced students in psychology, philosophy, and the cognitive sciences, including those who are not familiar with Over’s thought already.

This volume presents detailed reviews and will be of use to anyone interested in the strengths and weaknesses of human reason. This volume will also be of use to both proponents and skeptics of dual-process theory as it represents a strong case for the wide theoretical significance of the distinction between intuition and reflection. The empirical evidence indicates that analytic thinking plays a significant role in everyday life. Reason does, in fact, matter.

Thought insertion is the delusion that one's thoughts are not one's own, which causes people to believe that external agents have inserted ideas or thoughts into their minds. More prevalent in schizophrenia, thought insertion has been regarded as one of the most complex psychiatric symptoms. It is easy to see why it is such an intriguing phenomenon, as it blurs our understanding of some of the most fundamental aspects of our mind. Typically, discussions around thought insertion have tended to be featured in the context of philosophical examinations of broader issues in philosophy and psychiatry, or treated as a footnote to discussions of more prominent topics such as motor agency or the structure of phenomenal consciousness. For this reason, discussion of the phenomenon is incomprehensive and scattered throughout the literature, making it difficult to keep track of. Intruders in the Mind is an interdisciplinary attempt to bring together high-quality contributions to some of the most fundamental debates arising from the comprehensive study of thought insertion. Making thought insertion its central topic, this compilation gathers a series of essays that, taken as a whole, offer a broad and thoughtful approach to the clinical, phenomenological, conceptual, and experimental aspects of the systematic study of the phenomenon.
