The latest installment in the History of Psychology in Autobiography series takes readers through the personal and intellectual journeys of nine eminent people whose research has propelled the field of psychology into the 21st century. Each featured psychologist narrates how historical circumstances, collaborations, internal struggles, and public conflict led him or her to choose and develop various lines of research. Over the past 50 years, psychology has expanded from behaviorism and psychoanalysis into cognitive and social theories of learning and brain-based models of behavior and memory. Contributors to this volume document their role in these and other movements, including personality theory and assessment and child development. Editors Gardner Lindzey and William M. Runyan have brought together a collection of essays that put a human face on the maturing science of psychology.
