The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Subject of the Question**: The question asks about the experiments performed by Ivan Pavlov. 2. **Recognize Ivan Pavlov's Background**: Ivan Pavlov was a Russian physiologist known for his work in the field of psychology and physiology. 3. **Determine the Focus of His Experiments**: Pavlov is most famous for his experiments on conditioned reflexes. He studied how organisms learn through these reflexes. 4. **Explain the Theory of Conditioning**: Pavlov developed the theory of conditioning, which explains how behavior can be modified based on stimuli. He demonstrated that organisms can learn to associate a neutral stimulus with a significant one. 5. **Describe the Famous Experiment**: Pavlov conducted a well-known experiment with dogs. He would ring a bell before presenting food to the dogs. Initially, the dogs would salivate only when they saw the food. 6. **Observe the Conditioned Response**: Over time, the dogs began to salivate in response to the sound of the bell alone, even when no food was presented. This demonstrated that the dogs had learned to associate the bell (the neutral stimulus) with the food (the significant stimulus). 7. **Conclude the Correct Answer**: Based on his work with conditioned reflexes, the correct answer to the question is that Ivan Pavlov performed experiments on conditioned reflexes. **Final Answer**: Ivan Pavlov performed experiments on conditioned reflexes. ---
