The theory that every behavior is attained due to training and conditioning is known as Behaviorism which is a concept of learning. Conditioning or training happens due to contact with the surroundings. The theory of behaviorism states that behavior should be considered in a methodical and apparent way with no thought of the inner state of mind. According to Diane H. Tracey “two underlying assumptions are present in all theoretical versions of behaviorism. The first is the belief that behavior is the result of an organism’s or person’s response to stimuli. The second is the belief that external stimuli can be manipulated to strengthen or reduce an organism’s or an individual’s behavior.” The two main forms of conditioning are classical conditioning and operant conditioning. Classical conditioning demonstrates Behaviorism for the reason that it centers on apparent alterations in behavior and reaction to incentives or stimuli as representative of learning. Pavlov was the creator of classical conditioning as he observed that his dogs started to salivate as soon as they saw their bowls in which they were fed, despite the fact they were empty. He assumed that the dogs salivated as they had formed a connection between the existence of their bowls with the occurrence of their dinner.
