Classical v Operant

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.

First described by Ivan Pavlov, a Russian physiologist
Involves placing a neutral signal before a reflex
Focuses on involuntary, automatic behaviorsFirst described by B. F. Skinner, an American psychologist
Involves applying reinforcement or punishment after a behavior
Focuses on strengthening or weakening voluntary behaviors

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 the presentation of 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.

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.

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 making an association between an involuntary response and a stimulus, while operant conditioning is about making an association 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.

Today, both classical and operant conditioning are utilized for a variety of purposes by teachers, parents, psychologists, animal trainers and many others. In animal training, 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 treat or extra play time.
