Students First. Understanding Psychology is written around the philosophy that an effective textbook must be oriented to students—informing them, engaging them, exciting them about the field, and expanding their intellectual capabilities—because when students understand psychology, they learn psychology. No matter what brings students into the introductory course and regardless of their initial motivation, Understanding Psychology, Eighth Edition, draws students into the field and stimulate their thinking. This revision integrates a variety of elements that foster students’ understanding of psychology and its impact on their everyday lives. It also provides instructors with a fully integrated supplements package to objectively gauge their students’ mastery of psychology’s key principles and concepts and to create dynamic lectures.
