The book provides an overview of recent studies on intelligence to help readers develop a sound understanding of results and perspectives in intelligence research. In this volume, the editors bring together a group of respected experts from two fields of intelligence research-cognition and methods-to summarize, review, and evaluate research in their areas of expertise. The chapters in this book present state-of-the art examinations of a particular domain of intelligence research and highlight important methodological considerations, theoretical claims, and pervasive problems in the field. It provides those with a broad interest in individual differences, cognitive abilities, intelligence, educational measurement, thinking, reasoning, or problem solving with a comprehensive description of the status quo and prospects of intelligence research.
