What the concept of learning occurs when an animal links two events that occur together?

The concept of learning that occurs when an animal links two events that happen together is known as classical conditioning. This type of learning involves forming an association between a neutral stimulus and an unconditioned stimulus, leading to a conditioned response. A classic example is Pavlov's dogs, where the sound of a bell (neutral stimulus) became associated with food (unconditioned stimulus), causing the dogs to salivate (conditioned response) at the sound of the bell alone.
