The 1950s was the origin of the Cognitive Revolution, when the mind was first viewed as a computational, symbol-processing machine. A succession of other ideas has been offered to understand mind and behavior. Some approaches were initially scorned, such as evolutionary psychology; others were influential immediately, such as cognitive neuroscience. This seminar traces the different disciplines that have contributed to modern conceptions of mind, including anthropology, economics, and animal behavior. Students will be able to choose their own question of interest for focused exploration while the class broadly studies this explosive half-century of intellectual evolution.
