The concept of classical conditioning is based upon the experiments conducted by Ivan Pavlov.
1. Ivan Pavlov, a Russian physiologist, is known for his famous experiment involving dogs and the conditioning of their salivary responses.
2. In his experiment, Pavlov rang a bell every time he fed the dogs. Over time, he noticed that the dogs started to salivate at the sound of the bell even when no food was present.
3. This process of associating a neutral stimulus (the bell) with a reflex response (salivation) is the foundation of classical conditioning.
4. Pavlov's work laid the groundwork for understanding how behaviors could be learned through associations, influencing the field of psychology significantly.
Therefore, the correct answer to the question is A. Ivan Pavlov. His experiments and observations on classical conditioning are fundamental to the concept.
