The latest edition of a "classic"* For the fourth edition of this widely used text, new chapters have been added on moral development, prosocial behavior, and environmental factors in social behavior, and the entire text has been lavishly illustrated. "Perhaps the sprightliest version of [this] ... well-executed text. ... The writing is as always lean and clear. ... Issues and theoretical concepts are presented straightforwardly and are followed by a reasonable amount of the empirical consequences. ... A most eye-appealing product." --*Contemporary Psychology
