What is the Classical Conditioning ?
The Classical Conditioning by Ivan Pavlov says that the paring of a conditional stimulus (bell) with an unconditioned stimulus (meat) elicits an unconditioned response (salivation). Repetition produces a conditional reflex in which the bell alone elicits salivation in his dog.
On the other hand in the Operant Conditioning by Skinner learning occurs as a consequence of reinforcement. If a response is reinforced, its frequency will increase, but if it is punished, its frequency will decrease.
