Social psychology is the study of how normal people think, feel and behave as influenced by (real or imagined) others. This collection picks up from Michael Hogg's influential set, Social Psychology, published in 2002 to set out and explain the several changes the field has gone through since the mid-nineties. Social psychology now places more emphasis on studying the brain, cognitive-to-bodily effects, and goal pursuit. Classic topics such as prejudice, motivation, emotion, and interpersonal relationships are prominent still as this collection also illustrates. The articles selected include influential theories and conceptual reviews, feature empirical articles on edgy new theories, showcase state-of-the-art methodological advances and cover topics of perennial interest in the field. Volume One: General Principles covers major theories that advanced the field's thinking, including some that sparked much debate. Volume Two: Cognition includes the latest advances in the thoughts, beliefs, and attitudes that pertain to the social world and cover topics such as person perception, social cognition and attitudes. Volume Three: Emotion and Motivation provides a much-needed collection of the surge in recent years in theory and debate related to emotion. This volume also includes articles on self-regulatory resource depletion, the regulation of eating, law, monitoring progress toward goals and implementation intentions. Interpersonal relations are at the heart of the field so Volume Four: Interpersonal Processes is rich with the latest work on topics such as forgiveness, liking, rejection, aggression, prejudice, intergroup relations, sex and morality.
