Abstract During the 1980’s a Russian psychologist, Ivan Pavlov used some dogs which he attached to a device to hold it in place. He also had a bell, dog treats, and a wall that hid Pavlov from the dog’s view. During the experiment Pavlov would ring the bell and present the dogs with food to determine the dogs conditioned responses. After a period, the dogs began to connect hearing the bell with the presence of food when it entered in the room and began to salivate whenever the bell was rung. The result of Pavlov’s experiment was that conditioning an organism in this case the dogs to expect food when a bell is rung. When this occurs, the dogs begin to salivate in
The dogs associated the bell and the food, and the new behavior had been conditioned into the dogs its called conditioned stimulus. Classical conditioning has become famous since 1890-1930.

Pavlov’s Experiment Steps
Pavlov puts the food on the dog’s tongue. The dogs salivate demonstrating an unconditioned stimulus.
Pavlov rings the bell and gives the dogs food for the 1st couple of times demonstrating a neutral stimulus.
Pavlov rang bell (before presenting food) and waited to see what happened. the dog salivated demonstrating a conditioned stimulus.
1. Food in mouth produces salivation.
2. Pavlov walks into the room, then places food in the dog’s mouth.
3. Pavlov walks into the room, feeds the dogs (day after day after day)
4. Dogs eventually start to salivate when Pavlov walks into the room.
5. Pavlov now causes the dogs to
