Thoroughly updated to include the latest research available, THEORIES OF PERSONALITY, 10E takes a unique "theory by theory" approach that carefully guides students through major theories on their way to a comprehensive understanding of personality. Richard Ryckman's student-friendly writing style offers a straightforward presentation of major theories, helping readers more easily distinguish between them. The text begins by providing a framework that defines personality and emphasizes the science of personality--including the interrelation between research and theory. Next it introduces each major theoretical position with an objective overview of the theorist's basic concepts and principles. It concludes by noting the ways in which the different theories stimulate additional research efforts and by presenting five current research trends resulting from the work of these earlier theorists. The result is a text that merges the best of classic and contemporary research to equip students with a solid working knowledge of personality.
