Difference in classical and operant conditioning
Learning in psychology(esp. Behavioral Psychology) is through classical or operant conditioning. Its a change in behavior depending on the environment.
Pavlo's dog experiment was Classical conditioning. Conditional Stimulus(Bell) comes before the change in action.
Consequences lead to change in voluntary behavior
Eg. Giving a child candy for doing something good. Conditioning is after the action.
Eg. Beating a child for doing something wrong.
