Psychology is a vast and complex area of inquiry, and students entering the field may be confounded by the number of subfields within the discipline. Professor Russell A. Dewey of Georgia Southern University has created this fine online introductory textbook that covers everything from states of consciousness to social psychology. The online text includes sixteen chapters, and each chapter contains a number of parts that break each topic into smaller subtopics. The text is well-written and it draws on a number of examples and well-known experiments that will keep readers engaged. The site is rounded out by the inclusion of Professor Dewey's contact information and links to additional resources.
