"Bernard Nijstad is one of the 'young lions' of this field and has made substantial contributions to a number of the content areas covered in the book. Group Performance handles the conceptual and empirical material very well, leaving the reader with a good sense of what we currently know about the psychology of behavior in and by groups.Overall an excellent introduction to the area." - R. Scott Tindale, Loyola University, Chicago, USA"Bernard Nijstad, a brilliant and enthusiastic researcher, provides a comprehensive, cutting-edge perspective on a fascinating area of social psychology. This textbook will be a classic. I seriously could not stop reading it until the very last page. Highly recommended!" - Andreas Mojzisch, Institute of Psychology, University of Goettingen, Germany"Professor Nijstad does a fantastic job integrating both classic and contemporary research on group performance. I was particularly impressed with Nijstad’s ability to translate this literature in a well-organized and proficient manner. Nijstad’s enthusiasm for this work should help generate excitement in students reading about this topic for the first time." - Robert B. Lount, Jr., The Ohio State University, USA
