Social learning approach emphasizes on personality development through experiences. Some behaviour patterns are learned through direct experience; the individual behaves in a certain manner and in rewarded or punished. But responses can also be acquired without direct reinforcement.
Because we can make use of complex symbolic processes to code and store our observations in memory, we can learn by observing the actions of others and by noting the consequences of those actions.
Thus, for social learning theorists, reinforcement is not necessary for learning, although it may facilitate learning by focusing attention. Much of human learning is observational or vicarious.
