"Psychology is full of agreements and disagreements! Here Richard Gross pairs up 30 studies to show you how the classic theories in psychology are constantly revisited by modern researchers. In a new focus for this 6th edition, the emphasis is on how these classic and contemporary studies relate. From the differences and similarities between them you'll understand not just the studies themselves, but develop the study skills you need to write about psychology in exams and essays. Each study is summarized in simplified form, explaining jargon along the way. The background, methods, and findings are all set out and clearly interpreted. Crucially there is loads of evaluation help and pointers for developing your own evaluation skills in each pairing." --Publisher description.
