This history of modern scientific psychology ranges from the publication of Fechner's Elements of Psychophysics in the mid-19th century to the present. It focuses on current academic concerns, but also addresses material prior to the founding of psychology as a science. The author explores the implications of the new approach to cognitive science called connectionism, a radical approach to theorizing about cognition. He synthesizes the rapidly growing area of the history of psychology with general history, drawing upon major thinkers from various disciplines.
