Classical conditioning involves learning through association, where a neutral stimulus becomes associated with a meaningful stimulus to elicit a reflexive response. Operant conditioning, on the other hand, focuses on learning through consequences, where behaviors are strengthened or weakened based on the consequences they bring about, such as rewards or punishments.
Key Takeaways
- Classical conditioning is a learning process in which a previously neutral stimulus triggers an innate response.
- Operant conditioning is a learning process in which behavior is modified through consequences such as reinforcement or punishment.
- Classical conditioning involves the automatic response of an organism, while operant conditioning involves the deliberate actions of an organism.
Classical Conditioning vs Operant Conditioning
Classical conditioning, discovered by Ivan Pavlov, is a type of learning in which an organism learns to associate two previously unrelated stimuli and is concerned with the involuntary behaviours of an individual. Operant conditioning, discovered by B.F. Skinner is a type of learning in which an organism learns to associate a behaviour with a consequence and is responsible for making voluntary action weak or strong.
Classical conditioning is known to link a response that is involuntary with a stimulus. On the other hand, operant conditioning connects a voluntary action with a consequence.
No individual can choose to be or not be a part of new behaviour, in the case of classical conditioning.
However, in operant conditioning, the individual decides to receive a punishment or reinforcement by choosing to be or not to be a part of it. Parents and teachers mostly use operant conditioning to teach kids about certain behavioural aspects.

What is Classical Conditioning?
Classical conditioning, pioneered by Ivan Pavlov in the late 19th century, is a type of learning in which an organism comes to associate stimuli. It involves the formation of associations between previously unrelated stimuli through repeated pairings.
The Components of Classical Conditioning
Unconditioned Stimulus (UCS)
The unconditioned stimulus is a stimulus that naturally and automatically triggers a response without any prior learning. In Pavlov’s famous experiment, the food served to the dogs acted as the unconditioned stimulus, as it elicited the salivation response without any prior training.
Unconditioned Response (UCR)
The unconditioned response is the innate, reflexive response elicited by the unconditioned stimulus. In Pavlov’s experiment, the dogs’ salivation in response to the food served represented the unconditioned response.
Conditioned Stimulus (CS)
The conditioned stimulus is a neutral stimulus that, after being paired with the unconditioned stimulus, comes to evoke a response similar to the unconditioned response. For instance, in Pavlov’s experiment, the ringing bell initially served as a neutral stimulus but became a conditioned stimulus after being consistently paired with the presentation of food.
Conditioned Response (CR)
The conditioned response is the learned response elicited by the conditioned stimulus. In Pavlov’s experiment, the dogs’ salivation in response to the ringing bell, after it had been associated with the presentation of food, represented the conditioned response.
The Process of Classical Conditioning
- Acquisition: This is the initial stage of learning where the association between the conditioned stimulus and the unconditioned stimulus takes place. During this stage, the conditioned stimulus is repeatedly paired with the unconditioned stimulus until the association is formed.
- Extinction: Extinction occurs when the conditioned stimulus is presented repeatedly without the unconditioned stimulus, leading to a decrease in the conditioned response. In other words, if the bell is rung repeatedly without presenting food to the dogs, eventually, they will stop salivating in response to the bell.
- Spontaneous Recovery: After a period of extinction, if the conditioned stimulus is presented again, there might be a temporary reappearance of the conditioned response. However, this response is usually weaker than the original conditioned response.
- Generalization and Discrimination: Generalization refers to the tendency of a conditioned response to occur to stimuli that are similar to the conditioned stimulus. Discrimination, on the other hand, involves the ability to distinguish between the conditioned stimulus and other similar stimuli.
Applications of Classical Conditioning
Classical conditioning principles have been applied in various fields, including education, therapy, marketing, and animal training. Understanding classical conditioning can provide insights into how behaviors are learned and can be modified or controlled through environmental stimuli.
What is Operant Conditioning?
Operant conditioning, formulated by B.F. Skinner, is a type of learning in which behaviors are strengthened or weakened by the consequences that follow them. Unlike classical conditioning, which focuses on involuntary responses, operant conditioning emphasizes voluntary behaviors and how they are influenced by their outcomes.
The Components of Operant Conditioning
Reinforcement
Reinforcement involves the process of increasing the likelihood of a behavior occurring again in the future by providing a consequence that follows the behavior. Reinforcement can be positive, where a desirable stimulus is presented, or negative, where an aversive stimulus is removed.
Positive Reinforcement: Positive reinforcement involves presenting a desirable stimulus following a behavior, which increases the likelihood of that behavior being repeated. For example, praising a student for completing their homework on time is a form of positive reinforcement.
Negative Reinforcement: Negative reinforcement involves the removal of an aversive stimulus following a behavior, which also increases the likelihood of that behavior being repeated. An example of negative reinforcement is turning off a loud alarm by waking up and getting out of bed.
Punishment
Punishment involves the process of decreasing the likelihood of a behavior occurring again in the future by providing a consequence that follows the behavior. Punishment can be positive, where an aversive stimulus is presented, or negative, where a desirable stimulus is removed.
Positive Punishment: Positive punishment involves presenting an aversive stimulus following a behavior, which decreases the likelihood of that behavior being repeated. For instance, receiving a parking ticket for parking in a restricted area is a form of positive punishment.
Negative Punishment: Negative punishment involves the removal of a desirable stimulus following a behavior, which also decreases the likelihood of that behavior being repeated. An example of negative punishment is taking away a child’s favorite toy as a consequence for misbehaving.
The Process of Operant Conditioning
- Discriminative Stimulus (SD): The discriminative stimulus is a cue or signal that indicates the availability of reinforcement for a particular behavior. It sets the occasion for the behavior to occur. For example, a green light serves as a discriminative stimulus for a driver to accelerate their car.
- Response (R): The response is the behavior emitted by the organism. It can be any observable action, such as pressing a lever, speaking a word, or raising a hand.
- Consequence (C): The consequence follows the response and can be either reinforcing or punishing, depending on its effect on the likelihood of the behavior occurring again in the future.
- Schedules of Reinforcement: Reinforcement can be delivered according to various schedules, including continuous reinforcement (reinforcement after every occurrence of the behavior) or partial reinforcement (reinforcement after some, but not all, occurrences of the behavior), which can be further classified into ratio schedules or interval schedules.
Applications of Operant Conditioning
Operant conditioning principles have been widely applied in areas such as education, parenting, workplace management, and animal training. Understanding how behaviors are influenced by their consequences can help individuals and organizations shape behavior effectively and achieve desired outcomes.
Main Differences Between Classical Conditioning and Operant Conditioning
- Type of Behavior:
- Classical conditioning involves involuntary responses or reflexes.
- Operant conditioning involves voluntary behaviors.
- Focus on Stimuli:
- In classical conditioning, the focus is on the association between stimuli.
- In operant conditioning, the focus is on the relationship between behavior and its consequences.
- Role of Consequences:
- Classical conditioning relies on the pairing of stimuli without considering consequences.
- Operant conditioning emphasizes the consequences of behavior, where reinforcement strengthens behavior and punishment weakens it.
- Response Type:
- Classical conditioning deals with automatic, reflexive responses.
- Operant conditioning deals with emitted, voluntary behaviors.
- Learning Mechanism:
- Classical conditioning involves forming associations between stimuli.
- Operant conditioning involves learning through the consequences of behavior.
