The correct answer is classical conditioning
Classical conditioning is a learning process that occurs through associations between an environmental stimulus and a natural stimulus.
Classical conditioning is a type of learning that had a great influence on behavioral psychology, a systematic approach to psychology that emerged in the 19th century and that assumes that many behaviors are the product of an association, reflexes produced by a conditioned response to certain stimuli. This association, moreover, is a consequence of that person's history.
Russian physiologist Ivan Pavlov, along with John B Watson, is the greatest exponent of classical conditioning, one of the key processes of behavioral psychology and behaviorism, along with operant and instrumental conditioning.
