Document Summary
Learning is a relatively enduring change in behaviour that results from experience. Classical conditioning occurs when a neutral object comes to elicit a reflexive response when it is associated with a stimulus that already produce that response. A neutral stimulus unrelated to the salivary reflex, a bell, is presented together with a stimulus that reliably produces the reflex, such as food to the dog. This pairing, or conditioning trial is repeated a number of times. Then, on critical trials, the bell sound is presented alone and it is found that salivary reflex is measured. Under these conditions, pavlov found that the sound of the bell alone produced salivation as the dog has learned to associate the bell with food. This type of learning is referred to as classical conditioning. Unconditioned response (ur) is a response that does not have to be learned. Unconditioned stimulus (us) is a stimulus that elicits a response without any prior learning.
