The publication of this five-volume set represents a substantial revision and update of "Magill's Encyclopedia of Social Science: Psychology". The new encyclopedia covers not only the history of the field and the core aspects of behaviorism, cognitive psychology, and psychoanalytic psychology but also diagnoses, disorders, treatments, tests, notable people, and issues, including many popular concepts. Many of the newly added essays address how culture, ethnicity, and gender affect psychological theory and beliefs. They cover topics such as multicultural psychology and the effect of culture on diagnosis and look at groups as divergent as Latinos, Asian Americans/Pacific Islanders, and the gay, lesbian, bisexual, and transgender communities. Some examine gender differences, in particular gender roles and conflicts. Other essays examine important and developing issues in psychology, such as multiple intelligences, emotional intelligence, pharmaceuticals used in treatment, genetics, and the effects of hope, spirituality, and social support. Organization and format: The essays in this set range from one to eight pages in length. Every entry begins with standard information, including any relevant dates, the type of psychology and the field(s) of study. Biographical entries also include an 'Identity' line indicating nationality and specialty. The text of each article offers a clear and concise discussion of the topic. An entry on a mental illness addresses its cause, diagnosis, treatment, and impact. An entry on a theory or school examines its origin, history, and current status.
