David Matsumoto uses cross-cultural research as a platform to evaluate psychology as we know it and shows readers how to develop their own critical thinking skills. He encourages readers to raise questions about traditional knowledge and theories and to investigate the world around them so they can reap the benefits of diversity and turn its challenges into assets. The Second Edition has been thoroughly updated to reflect current developments in the field and provides an overview of how culture affects psychology to give students a framework they can use throughout the book.
