Behaviourism

A psychological approach to understanding abnormal behaviour devised by John B. Watson (1858–1935), which declared that psychology must be restricted to the study of observable features, that is, the behaviour of organisms. Watson considered abnormal functioning to be learned and so believed it could be unlearned. His model for learning was derived from Ivan Pavlov’s (1849–1936) studies of classical conditioning.

Classical Conditioning

A learning process where a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit similar responses.
