Classical and operant conditioning are two important concepts central to behavioral psychology. While both result in learning, the processes are quite different. In order to understand how each of these behavior modification techniques can be used, it is also essential to understand how classical conditioning and operant conditioning differ from one another.

Let's start by looking at some of the most basic differences.

Classical Conditioning

  • First described by Ivan Pavlov, a Russian physiologist
  • Involves placing a neutral signal before a reflex
  • Focuses on involuntary, automatic behaviors

Operant Conditioning

  • First described by B. F. Skinner, an American psychologist
  • Involves applying reinforcement or punishment after a behavior
  • Focuses on strengthening or weakening voluntary behaviors

How Classical Conditioning Works

Even if you are not a psychology student, you have probably at least heard about Pavlov's dogs. In his famous experiment, Ivan Pavlov noticed dogs began to salivate in response to a tone after the sound had been repeatedly paired with presenting food. Pavlov quickly realized that this was a learned response and set out to further investigate the conditioning process.

Classical conditioning involves pairing a previously neutral stimulus (such as the sound of a bell) with an unconditioned stimulus (the taste of food).

This unconditioned stimulus naturally and automatically triggers salivating as a response to the food, which is known as the unconditioned response. After associating the neutral stimulus and the unconditioned stimulus, the sound of the bell alone will start to evoke salivating as a response. The sound of the bell is now known as the conditioned stimulus and salivating in response to the bell is known as the conditioned response.

Classical conditioning is much more than just a basic term used to describe a method of learning; it can also explain how many behaviors form that can impact your health. Consider how a bad habit might form. Even though you have been working out and eating healthy, nighttime overeating keeps tripping up your dieting efforts.

Thanks to classical conditioning, you might have developed the habit of heading to the kitchen for a snack every time a commercial comes on while you are watching your favorite television program. While commercial breaks were once a neutral stimulus, repeated pairing with an unconditioned stimulus (having a delicious snack) have turned the commercials into a conditioned stimulus. Now every time you see a commercial, you crave a sweet treat.

How Operant Conditioning Works

Operant conditioning focuses on using either reinforcement or punishment to increase or decrease a behavior. Through this process, an association is formed between the behavior and the consequences for that behavior.

For example, imagine that a trainer is trying to teach a dog to fetch a ball. When the dog successful chases and picks up the ball, the dog receives praise as a reward. When the animal fails to retrieve the ball, the trainer withholds the praise. Eventually, the dog forms an association between his behavior of fetching the ball and receiving the desired reward.

In addition to being used to train people and animals to engage in new behaviors, operant conditioning can also be used to help people eliminate unwanted ones. Using a system of rewards and punishments, people can learn to overcome bad habits that might have a negative impact on their health such as smoking or overeating.

The Differences Between Classical and Operant Conditioning

One of the simplest ways to remember the differences between classical and operant conditioning is to focus on whether the behavior is involuntary or voluntary. Classical conditioning involves associating between an involuntary response and a stimulus, while operant conditioning is about associating between a voluntary behavior and a consequence

In operant conditioning, the learner is also rewarded with incentives, while classical conditioning involves no such enticements. Also, remember that classical conditioning is passive on the part of the learner, while operant conditioning requires the learner to actively participate and perform some type of action in order to be rewarded or punished. For operant conditioning to work, the subject must first display a behavior which can then be either rewarded or punished. Classical conditioning, on the other hand, involves forming an association with some sort of already naturally occurring event. 

Today, both classical and operant conditioning are utilized for a variety of purposes by teachers, parents, psychologists, animal trainers, and many others. In animal conditioning, a trainer might utilize classical conditioning by repeatedly pairing the sound of a clicker with the taste of food. Eventually, the sound of the clicker alone will begin to produce the same response that the taste of food would.

In a classroom setting, a teacher might utilize operant conditioning by offering tokens as rewards for good behavior. Students can then turn in these tokens to receive some type of reward such as a treat or extra play time. In each of these instances, the goal of conditioning is to produce some sort of change in behavior.
