Adopted at nearly 200 colleges and universities, the First Edition of Psychological Science was the most successful new introductory psychology text published in over a decade. Building on its unique strengths — a rigorous and scientific treatment of contemporary psychology, a clear writing style, and a focus on principles rather than encyclopedic detail — the text has been meticulously revised and reorganized for greater balance and accessibility. The Second Edition offers significantly expanded coverage of cultural and social psychology, strengthened integration of contemporary and classic studies, an enriched emphasis on critical thinking, and groundbreaking new multimedia learning tools.
