Operant Conditioning Theory

B. F. Skinner

B. F. Skinner (1904 - 1990) was the behaviorist who assumed leadership of the field after John Watson. He was even more determined than Watson that psychologists should study only measurable, observable behaviour. In addition to his knowledge of Pavlovian classical conditioning, Skinner found in the work of Thorndike a way to explain all behavior as the product of learning. He even gave the learning of voluntary behavior a special name: Operant Conditioning. Voluntary behavior is that which people do to operate in the world. So voluntary behavior for Skinner is operant behavior and the learning of such behavior is operant conditioning. 


Operant Conditioning is a type of learning. It is very similar to the classical conditioning. The term "Operant" refers to how an organism operates on the environment, and hence, operant conditioning comes from how we respond to what is presented to us in our environment. It can be thought of as learning due to the natural consequences of our actions.

The classic study of Operant Conditioning involved a cat who was placed in a box called "Skinner box" or "operant conditioning chamber, with only one way out; a specific area of the box had to be pressed in order for the door to open. The cat initially tries to get out of the box because freedom is reinforcing. In its attempt to escape, the area of the box is triggered and the door opens. The cat is now free. Once placed in the box again, the cat will naturally try to remember what it did to escape the previous time and will once again find the area to press. The more the cat is placed back in the box, the quicker it will press that area for its freedom. It has learned, through natural consequences, how to gain the reinforcing freedom.

We learn this way every day in our lives. Imagine the last time you made a mistake; you most likely remember that mistake and do things differently when the situation comes up again. In that sense, you’ve learned to act differently based on the natural consequences of your previous actions. The same holds true for positive actions. If something you did results in a positive outcome, you are likely to do that same activity again.

Classical Conditioning Theory

Classical Conditioning is one important type of learning. It was actually discovered accidentally by Ivan Pavlov (1849-1936). Pavlov was a Russian physiologist who discovered this phenomenon while doing research on digestion. His research was aimed at better understanding the digestive patterns in dogs.

During his experiments, he would put meat powder in the mouths of dogs who had tubes inserted into various organs to measure bodily responses. What he discovered was that the dogs began to salivate before the meat powder was presented to them. Then, the dogs began to salivate as soon as the person feeding them would enter the room. He soon began to gain interest in this phenomenon and abandoned his digestion research in favor of his now famous Classical Conditioning study.

Basically, the findings support the idea that we develop responses to certain stimuli that are not naturally occurring. When we touch a hot stove, our reflex pulls our hand back. It does this instinctually, no learning involved. It is merely a survival instinct. But why now do some people, after getting burned, pull their hands back even when the stove is not turned on? Pavlov discovered that we make associations which cause us to generalize our response to one stimuli onto a neutral stimuli it is paired with. In other words, hot burner = ouch, stove = burner, therefore, stove = ouch.
