The printed textbook, "Psychology: The Core," covers the core content of psychology--the essentials that every introductory psychology student should know. The book is briefer than a standard introductory text, allowing for a lower cost to students and using less printed paper. It includes study aids students have told us they find useful--concept maps, note-taking features, and a laminated study card highlighting the most challenging topics in introductory psychology. The website "www.PsychologyTheCore.com," provides more in-depth treatment of topics, up-to-date statistics, cutting edge research, simulations, video clips, and real-world applications of psychology. A monthly blog provides an opportunity for us to post interesting links and new research findings and to respond to questions from our readers. Annual updates to the site will ensure that readers have access to all the latest findings.
