Five chances to win a copy of The Rough Guide to Psychology

Thanks for all your interesting entries. This competition is now closed and the winners have been contacted.

To celebrate worldwide sales in excess of 10,000 copies, Rough Guides have kindly donated to us 5 copies of The Rough Guide to Psychology by Digest editor Christian Jarrett. From the reviews:

Professor Uta Frith DBE said the The Rough Guide is "disarmingly appealing to the deep desire to know ourselves" and presents "psychology today in a nutshell". Prof Robert Epstein said "It is accurate, up-to-date and easy to read ... For a rough guide, this book is smooth.” And psychologist, teacher and Guardian blogger Marc Smith said it's perhaps "the best introduction to the subject I have seen."
