Lefton/Brannon, Psychology empowers students to become active learners in their goal to understand, learn, and apply psychological methods and principles in their daily lives and in the world around them.

This new edition of Psychology has undergone the most extensive revision to date. The 9th edition reflects the needs of the instructor and student by presenting the concepts of psychological science and research within a pedagogical framework promoting active learning, and teaching and learning choices.

The authors' wide-ranging revision includes the reorganization of core chapters; the addition of a stand-alone chapter on research methods; expanded coverage of applied topics such as industrial-organizational psychology; a comprehensive review and updating of the diversity coverage; and an infusion of over 1,000 important new research references.

The text continues to emphasize four major themes throughout the text: the integration of diversity, the importance of biological/evolutionary topics, the complex relationship between nature and nurture, and the importance of students' ability to apply and critique basic psychological principles within their own lives.

The pedagogical structure reinforces the need for students to be active in their own learning process. Students are encouraged to become active members, along with their instructors, in the goal to understand, learn, and apply psychological methods and principles in their daily lives and in the world around them.
