Drawing on teaching and learning research, the Sixth Edition provides new tools to improve students' reading, focus, and self-assessment. Chapters are now divided into brief "study units," each of which concludes with a self-test question to increase comprehension. NEW "Putting Psychology to Work" features show students how to apply psychology concepts to future careers. Our formative, adaptive learning tool, InQuizitive, and our online psychology labs, ZAPS 2.0, provide a hands-on approach to assessing students' understanding.
