'This textbook is wonderfully written and a perfect resource for every psychology student. It captures a range of different viewpoints on gender and shows the need to consider both the role of culture and biological factors in how we understand what it means to be male or female. This book explores key topics at the heart of the discipline and reflects original ideas on the sex/gender binary. It is accessible, engaging and thought-provoking.' - Lewis Goodings, Lecturer in Social Psychology, University of Roehampton, London, UK
