Experimental research by social and cognitive psychologists has established that cooperative groups solve a wide range of problems better than individuals. Cooperative problem solving groups of scientific researchers, auditors, financial analysts, air crash investigators, and forensic art experts are increasingly important in our complex and interdependent society. This comprehensive textbook presents important theories and experimental research about group problem solving. The book focuses on tasks that have demonstrably correct solutions within mathematical, logical, scientific, or verbal systems, including algebra problems, analogies, vocabulary, and logical reasoning problems. It explores basic concepts in group problem solving, social combination models, group memory, group ability and world knowledge tasks, rule induction problems, letters-to-numbers problems, evidence for positive group-to-individual transfer, and social choice theory. The conclusion proposes ten generalizations that are supported by the theory and research on group problem solving. The book is an essential resource for decision-making research in social and cognitive psychology, but also extremely relevant to multidisciplinary and multicultural problem-solving teams in organizational behavior, business administration, management, and behavioral economics.

The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. This book overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, the book argues that “good genes” play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, the book explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. The book explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. The book broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, the book offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.

What's so special about music? We experience it internally, yet at the same time it is highly social. Music engages our cognitive/affective and sensory systems. We use music to communicate with one another—and even with other species—the things that we cannot express through language. Music is both ancient and ever evolving. Without music, our world is missing something essential. This book offers a social and behavioral neuroscientific explanation of why music matters. Its aim is not to provide a grand, unifying theory. Instead, it guides the reader through the relevant scientific evidence that links neuroscience, music, and meaning. It considers how music evolved in humans and birds, how music is experienced in relation to aesthetics and mathematics, the role of memory in musical expression, the role of music in child and social development, and the embodied experience of music through dance. It concludes with reflections on music and well-being. The book is a tour through the current research on the neuroscience of music.
