A conditioned response is a learned reaction that an individual exhibits automatically due to the repeated pairing of a neutral stimulus with an unconditioned stimulus. This process is a fundamental aspect of classical conditioning, a theory developed by the Russian physiologist Ivan Pavlov.
Definition and Mechanism
A conditioned response (CR) emerges when a neutral stimulus (NS) that initially does not elicit any specific response, becomes associated repeatedly with an unconditioned stimulus (US) that naturally and automatically triggers an unconditioned response (UR). After repeated pairings, the formerly neutral stimulus becomes a conditioned stimulus (CS), capable of triggering the response even in the absence of the unconditioned stimulus.
For example, if a tone (NS) is sounded immediately before presenting food (US) that causes salivation (UR) in a dog, the dog will eventually begin to salivate (CR) at the sound of the tone alone.
Types of Stimuli and Responses
- Neutral Stimulus (NS): A stimulus that initially does not elicit any inherent response.
- Unconditioned Stimulus (US): A stimulus that naturally triggers a response without conditioning.
- Unconditioned Response (UR): The natural, automatic reaction to the unconditioned stimulus.
- Conditioned Stimulus (CS): The previously neutral stimulus that after association with the unconditioned stimulus, triggers a conditioned response.
- Conditioned Response (CR): The learned reaction to the conditioned stimulus.
Historical Context
The concept of conditioned responses was first identified by Ivan Pavlov in the early 20th century. Pavlov’s experiments involved dogs, bells, and food, leading to the discovery of what he termed “conditional reflexes” now known broadly as conditioned responses.
Applications and Examples
Psychological Therapy
Conditioned responses are foundational to behavior therapy techniques such as systematic desensitization, which is used to treat phobias and anxiety disorders by gradually exposing individuals to the feared object or context without the associated fear.
Education and Learning
In educational settings, positive reinforcement (a conditioned stimulus like praise or rewards) can lead to conditioned responses such as increased motivation and improved performance.
Advertising
Advertisers use conditioned responses to forge positive associations with their products. By pairing a product (neutral stimulus) with positive images or music (unconditioned stimuli), they induce a positive emotional response (conditioned response) when consumers perceive the product.
Comparison with Related Terms
Classical Conditioning vs. Operant Conditioning
While classical conditioning (Pavlovian) involves learning through association between stimuli and responses, operant conditioning (Skinnerian) involves learning through the consequences of actions (rewards and punishments).
Unconditioned Response vs. Conditioned Response
An unconditioned response occurs naturally in reaction to a stimulus without prior learning, whereas a conditioned response is learned through the association of a neutral stimulus with an unconditioned stimulus.

Summary
A conditioned response is a powerful behavioral mechanism illustrating how learning influences behavior through association. Originating from Pavlov’s foundational work in classical conditioning, it explains a wide range of behaviors in both clinical and everyday contexts. Understanding conditioned responses provides valuable insights into therapeutic practices, educational methods, and even marketing strategies.
By deepening our comprehension of conditioned responses, we gain greater control over modifying and predicting behavior, highlighting its significance in both scientific research and practical application.
