Classical conditioning is where a conditioned response is used to cause a change in behavior. Pavlov documented a dog 's unconditioned response to food which is an unconditioned stimulus. Dogs have a predisposition naturally to start salivating when food is introduced. This condition is innate and similar to a person 's reflex of pulling his or her hand away from a hot stove. Pavlov also showed that a condition stimulus like the sound of a bell alone will not cause a dog to salivate. Pavlov added a conditioned stimulus, the sound of a bell, to the unconditioned stimulus of introducing food. After repeating the conditioned stimulus several times the dogs learned that when the bell sounded that food was going to follow so the dogs would start salivating as soon as they heard the sound of the bell even if no food was presented. (Willingham, 2007)Skinner studied learning through operant conditioning. Operant conditioning is different than classical conditioning because a choice is involved. The dog 's did not have a choice but to salivate to the sound of the bell, but in operant conditioning a person would make a choice such as not eat fish if it has made them sick on a prior experience. Skinner used a skinner box made of Plexiglas with a grid floor that can be electrified and a lever that can be pressed that will deliver food to the animal, usually a rat, inside the box. (Hergenhahn & Olson, 2005) The box was used to test escape conditioning or avoidance conditioning. Escape conditioning occurs when the animal inside the Skinner box is given a negative stimulus, an electoral shock from the floor of the box, and the animal has to perform a behavior such as climbing onto a small shelf to turn off the shock stimulus. (Hergenhahn & Olson, 2005) Avoidance conditioning is a signal is activated just before the electric shock to get the animal to jump onto the shelf to avoid being shocked. (Hergenhahn & Olson,
