In this volume, leading international cognitive psychologists elucidate and engage with the invaluable contribution of Paolo Legrenzi to the field of thinking and reasoning. Beginning with a look at the early influence of the Gestalt school, contributions go on to look in detail at research in reasoning, spatial inference, and working memory. The wider implications of Legrenzi's work into the relationship between linguistic formulation and conditional reasoning are covered as are the social and emotional aspects of decision making. Throughout, discussions are placed into the wider research context and implications for the field as a whole considered, making this an essential reference for anyone researching into the processes that inform our thinking, reasoning and decision making in everyday life.
