As an outcome of functionalism, experimental work on animal behaviour and its neurological foundations developed rapidly at Chicago, particularly at the hands of C. M. Child, G. E. Coghill, and J. B. Watson before he became a doctrinaire behaviourist. Indeed functionalism did much to lay the foundations of biological psychology as we know it today. The term functionalism is now more often used to denote functionalist theories of mind.
Functionalism emphasized learning by adapting to situations, and incorporating skills from largely unconscious learned behaviour. It introduced some evolutionary ideas into psychology because innate behaviour could be included. Consciousness was introduced when behaviour was not sufficiently functional to perform tasks unconsciously. Functionalism became swamped by behaviourism, which quite recently gave way to cognitive psychology.
