Comparing psychological variation across cultures requires accurate and appropriate methods. This book highlights methodological developments that promise to improve the work of social and behavioral scientists and practitioners. It covers acculturation and identity, individual differences, and features perspectives on future themes and challenges. 'This remarkable book, celebrating the legacy of Fons van de Vijver, takes the reader on a voyage from acculturation and identity, through the interaction between individual and context, to statistical, psychometric, and methodological considerations of culture and psychology. It is a must-read for researchers in the field.' Nicolas Geeraert, Senior Lecturer in Psychology, University of Essex, UK
