Classical Conditioning: Changing Behavior by Associating Stimuli

Classical Conditioning: Changing Behavior by Associating Stimuli

Understanding Classical Conditioning

Classical conditioning is a learning process first discovered by Ivan Pavlov in which a neutral stimulus begins eliciting a response after it is repeatedly paired with another stimulus that naturally elicits that response. For example, Pavlov’s dogs salivated when presented with food. After repeatedly pairing a bell sound with the presentation of food, the dogs began salivating when they heard the bell – even when no food was presented.

How Classical Conditioning Works

Classical conditioning involves pairing a neutral stimulus with a stimulus that naturally and automatically triggers a response. After repeated pairings, the previously neutral stimulus alone will come to trigger that response. This process relies on associative learning, or learning that certain events occur together. There are four key elements:

  • The unconditioned stimulus (UCS) – The stimulus that naturally and automatically triggers a response, such as food.
  • The unconditioned response (UCR) – The natural response to the UCS, such as salivation.
  • The conditioned stimulus (CS) – A neutral stimulus that does not naturally elicit a response, such as a bell sound.
  • The conditioned response (CR) – The learned response to the CS after repeated pairings with the UCS, such as salivation upon hearing the bell.

Real-World Applications

Classical conditioning has been used to help explain many behaviors and has practical applications as well:

  • Overcoming fears or phobias through systematic desensitization
  • Treating anxiety, PTSD, and panic disorders
  • Influencing consumer decisions through advertising that pairs products with positive stimuli
  • Improving athletic performance by associating practice with rewards

The Importance of Timing and Contiguity

In order for classical conditioning to occur efficiently, the CS and the UCS need to occur closely together in time. The stimuli also need to be contiguous, or touching. Having a small window between the CS and UCS allows the associated to be made more easily. If too much time passes between the stimuli, learning is less likely to occur.

FAQ

What is an example of classical conditioning?A classic example is Ivan Pavlov’s experiment training dogs to salivate at the sound of a bell by pairing food (which naturally made them salivate) with the sound of the bell. After some time, the dogs began salivating just from hearing the bell, even without getting food.What are the 4 key processes of classical conditioning? The 4 key processes are:

  1. The unconditioned stimulus (UCS)
  2. The unconditioned response (UCR)
  3. The conditioned stimulus (CS)
  4. The conditioned response (CR)

How is classical conditioning used in overcoming fears?Systematic desensitization uses classical conditioning principles to slowly expose someone to a feared stimulus in a safe, controlled way. This conditions a more positive response to the fear trigger.Why is timing important in classical conditioning? The conditioned stimulus and unconditioned stimulus need to occur closely together in time and be contiguous (touching) for the association between them to be made efficiently in the mind. Too much time between stimuli means slower or no conditioning. Does classical conditioning always involve a reflexive response?No, classical conditioning can connect any neutral stimulus to any behavior that has a natural or learned response. It often involves reflexive responses like salivation but can also condition emotional responses like fear.
