The Third Edition continues its successful combination of educational features that encourage the student to learn and make teaching easier for the instructor. Marginal questions scattered throughout the chapter help keep the student focused, while sectional Concept Checks and self tests provide immediate feedback on the student's understanding of the material. At the end of each chapter the student is encouraged toward further exploration by the web links found in Online Resources, the references in For Further Reading, and the probing questions of For Further Thought. Throughout the chapters, Application boxes take the student a step beyond the chapter material, and In the News features tell the student that biopsychology is both timely and relevant. The Third Edition devotes an entire chapter to intelligence and cognitive functioning and another to consciousness. Coming in the last unit of the text, these chapters assure that the student will walk away with the understanding that neuroscience is not only relevant but powerful enough to discover the foundations of our most defining characteristics.
