Answer: A - Ivan Pavlov is the scientist known to spearhead research studies in classical conditioning.
Key Takeaway: Ivan Pavlov is a Russian psychologist who pioneered research on classical conditioning. He trained a dog to respond to the sound of a bell by pairing it with food. Every time he gave the dog food, he rang a bell first. With the smell of the food, the dog would salivate. After enough times, the dog began to salivate at the ringing of the bell alone. He concluded that the ringing of the bell was the conditioned stimulus that the dog learned to associate with food.
