Originally published in 1989, this book offers a comprehensive overview of the work of scholars in several different disciplines contributing to the development of the psychology of science: the systematic elaboration and application of psychological concepts and methods to clarify the nature of the scientific enterprise. The psychology of science of course overlaps in important ways with the philosophy, history, and sociology of science, but its predominant and distinctive focus is on individuals and small groups employing concepts elucidated via experimental methods.
