Over the past three decades, there has been a rapid development of research on human thinking and reasoning. This volume provides a comprehensive review of this topic by looking at the important contributions Paolo Legrenzi has made to the field, by bridging the gap from Gestalt ideas to modern cognitive psychology. The contributors, including some of the most distinguished scholars of reasoning and thinking in Europe and the USA, reflect upon the ways in which he has influenced and inspired their own research, and contributed to modern approaches to human inference.

This volume draws on both traditional and new topics in reasoning and thinking to provide a wide-ranging survey of human thought. It covers creativity, problem-solving, the linguistic and social aspects of reasoning and judgement, and the social and emotional aspects of decision making through telling examples, such as the cognitive mechanisms underlying consumers' attitudes towards herbal medicines. It considers a series of key questions, such as how do individuals who are unfamiliar with logic reason? And how do they make choices if they are unfamiliar with the probability calculus and decision theory?

The discussions are placed throughout within a wider research context and the contributors consider the implications of their research for the field as a whole, making the volume an essential reference for anyone investigating the processes that underlies our thinking, reasoning, and decision-making in everyday life.
