Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
Pavlov started studying the digestive system in dogs by performing chronic implants of fistulas in the stomach, by which he was able to show with extreme clarity that the nervous system plays a dominant role in the regulation of the digestive process. Experiments on digestion led to the development of the first experimental model of learning ...
Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, IPA: [ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf] ⓘ; 26 September [O.S. 14 September] 1849 – 27 February 1936) [2] was a Russian and Soviet experimental neurologist and physiologist known for his discovery of classical conditioning through his experiments with dogs.
Ivan Pavlov conducted multiple experiments investigating digestion in dogs in which neutral, unconditioned, and conditioned stimuli were used. In these experiments, the neutral stimulus was the sound of a bell ringing. This sound was presented to the dogs along with food, which acted as an unconditioned stimulus.
Ivan Pavlov. The behavioristic approach to psychology reached its peak of popularity in the mid-twentieth century but still underlies much experimental research and clinical application. Its founders include such figures as Ivan Pavlov, John B. Watson, and B.F. Skinner. Pavlov's experimental study of the digestive system in dogs led to ...

Experiments conducted by M. Pawlow and his pupils add confirmation to the view that “all physiological phenomena may be completely studied as if psychical phenomena had no existence.” [3] Direct excitation of the mouth cavity of a dog produces an “unconditional” reflex secretion of the saliva. In case the exciting substance is something ...
