This document discusses the historical context and methodology of human learning research. It describes Rene Descartes' dualist view that the mind and body are separate but interacting, with voluntary behavior governed by the mind and involuntary reflexes governed by the body. It also discusses how Descartes' view led to the fields of mentalism and reflexology. Later researchers like John Locke debated nativism versus empiricism and whether ideas are innate or formed from experience. Comparative cognition research used animal models and experiments to better understand learning and neural functions.
