It then explains four major theories of learning: (1) classical and operant conditioning theories based on Pavlov and Skinner's experiments, (2) social learning theory which involves both observation and direct experience, and (3) cognitive theory which views learning through understanding thought processes and decision making. The document provides details on the key aspects and examples for each theory.
