The established author team of Susan Nolen-Hoeksema, Barbara Fredrickson and Geoffrey R. Loftus has been joined by Christel Lutz (University of Utrecht), who has helped to add a fresh European influence, and thereby create a truly international introductory textbook. The 'Cutting Edge Research' box features and 'Seeing Both Sides' essays which conclude each chapter have been fully updated and replaced throughout, using contributions from a range of experts across the globe, and really help to bring the text to life for students.
