1. Conditional reflex was demonstrated by Pavlov while performing experiments with dogs.
2. Pavlov offered some food to dog and noticed that the dog starts salivating after smelling and seeing the food.
3. Simultaneously he rang the bell so that the dog associated the food with the sound of bell. This experiment was repeated many a times by him.
4. Later he only rang the bell and did not give any food to the dog. But still the dog salivated.
5. This shows that the dog was conditioned to the sound of bell. The dog learnt that there is a relation between food and sound of bell. This is called conditional response.
