Each edition of a textbook must be as vital, dynamic, and responsive to change as the field it covers. To remain an effective teaching instrument, Theories of Personality, 12th edition must reflect the development of the field, both in theory and science-based knowledge, while also engaging and encouraging the learner. We have seen the focus of personality study shift from global theories, beginning with Sigmund Freud's 19th-century psychoanalytic theory of neuroses, to 21st-century models of how external and internal factors contribute to personality in nuanced ways. And we have seen the basis of personality exploration change from case studies of Western upper-middle-class patients with “neuroses” to systematic, scientific research with diverse populations. Contemporary work in the field is both conducted by and focuses on people diverse in gender, age, and sexual orientation as well as ethnic, racial, religious, and cultural heritage. -- Preface
