This unique book closes the gap between psychology textbooks and the research that made them possible. Its journey through the “headline history” of psychology presents 40 of the most famous studies in the history of the science, and subsequent follow-up studies that expanded their findings and relevance. Readers are granted a valuable insider's look at the studies that continue to be cited most frequently, stirred up the most controversy when they were published, sparked the most subsequent related research, opened new fields of psychological exploration, and changed most dramatically our knowledge of human behavior.
