Modern psychology began with the adoption of experimental methods at the end of the nineteenth century: Wilhelm Wundt established the first formal laboratory in 1879; universities created independent chairs in psychology shortly thereafter; and William James published the landmark work Principles of Psychology in 1890. In A History of Modern Experimental Psychology, George Mandler traces the evolution of modern experimental and theoretical psychology from these beginnings to the "cognitive revolution" of the late twentieth century. Throughout, he emphasizes the social and cultural context, showing how different theoretical developments reflect the characteristics and values of the society in which they occurred. Thus, Gestalt psychology can be seen to mirror the changes in visual and intellectual culture at the turn of the century, behaviorism to embody the parochial and puritanical concerns of early twentieth-century America, and contemporary cognitive psychology as a product of the postwar revolution in information and communication.
