who discovered classical conditioning

Ivan Pavlov, a Russian physiologist, is credited with discovering classical conditioning through his experiments with dogs in the late 19th century.

Quick Scoop

Who discovered classical conditioning?

• The person who discovered classical conditioning is Ivan Pavlov, not a psychologist but a physiologist studying digestion in dogs.

• While measuring dogs’ salivation to food, he noticed they began to salivate at signals that predicted food (like footsteps or a food dish), even before the food arrived.

• Pavlov then systematically paired a neutral signal (like a bell) with food and showed that the signal alone could trigger salivation, establishing what we now call “Pavlovian” or classical conditioning.

A small historical twist

• Some historians note that Edwin Twitmyer reported a similar conditioning effect with human knee-jerk reflexes about a year before Pavlov’s famous work, but Pavlov’s research became far more widely known and is what textbooks credit.

• Because of the depth and impact of his experiments, Pavlov’s name is firmly attached to the discovery and the method itself, hence the common term “Pavlovian conditioning.”
