Classical vs Operant Conditioning

The difference between operant conditioning and classical conditioning is the use of punishments and reinforcments. In operant conditioning, Skinner is trying to produce certain behavior through the help of punishments and reinforcments, this way you can condition a person or animal to behave in the desired way. In the other hand, classical conditioning does not use punishment or reinforcments. Pavlov was just showing how you can condition someone who associates a sound or smell or other things to a stimulus in able to have a desired response. In both methods you are trying to achieve certain behavior but in different ways.
