This image illustrates
classical conditioning, a fundamental concept in behavioral psychology first demonstrated by Ivan Pavlov. The diagram uses a baby and a mouse to explain how a neutral stimulus can become associated with an unconditioned stimulus to produce a learned (conditioned) response.
Let’s break it down step by step:
---
🔹 Step 1: Before Conditioning
-
Stimulus: Mouse (CS - Conditioned Stimulus)
-
Response: No response
-
Explanation: Initially, the mouse is a
neutral stimulus—it does not provoke any emotional reaction from the baby. This is the
Conditioned Stimulus (CS) before conditioning.
---
🔹 Step 2: Pairing of Stimuli (Acquisition)
-
Stimulus: Mouse (CS) + Loud noise (US - Unconditioned Stimulus)
-
Response: Fear response (UR - Unconditioned Response)
-
Explanation: The loud noise is an
unconditioned stimulus (US) that naturally and automatically triggers a
fear response (UR)—this is an innate reaction. When the mouse (CS) is repeatedly paired with the loud noise (US), the brain begins to associate the two.
> 🔄 This pairing is the core of classical conditioning: the neutral stimulus (mouse) becomes linked with the unconditioned stimulus (loud noise).
---
🔹 Step 3: After Conditioning
-
Stimulus: Mouse (CS)
-
Response: Fear response (CR - Conditioned Response)
-
Explanation: Now, even
without the loud noise, just seeing the mouse alone triggers fear. The mouse has become a
conditioned stimulus, and the fear response is now a
conditioned response (CR)—learned through association.

✔ Summary of Terms:
| Term | Definition |
|------|-----------|
|
CS (Conditioned Stimulus) | Originally neutral stimulus (mouse) that becomes meaningful after pairing. |
|
US (Unconditioned Stimulus) | Naturally triggering stimulus (loud noise). |
|
UR (Unconditioned Response) | Natural, automatic response to US (fear from loud noise). |
|
CR (Conditioned Response) | Learned response to CS (fear when seeing mouse). |

🧠 Real-Life Example:
This process mirrors how phobias can develop. For instance, if someone is startled by a loud noise while seeing a spider, they might eventually fear spiders even without the noise—because the spider has become a conditioned stimulus.
---
✔ Conclusion:
The diagram shows how
classical conditioning works:
> A neutral stimulus (mouse) → paired with an unconditioned stimulus (loud noise) → leads to a conditioned response (fear) to the original neutral stimulus.
This is a powerful example of
learning through association.
