An unconditioned stimulus UCS is stimuli or anything that brings out a reaction that is innate, not learned, automatic, etc.
A conditioned stimulus CS is a once neutral or unrelated stimulus that has been paired with an unconditioned stimulus, which after training and learning signals the conditioned response.
Take a dog for example. A dog will salivate at the sight of food, salivation is the unconditioned stimulus, dogs don't learn how to drool they just do. Then pair the sight of food with the ringing of a bell, once unrelated, and the dog will learn to associate the bell with food and will therefore salivate. And the bell becomes the conditioned stimulus.

CoachAn unconditioned stimulus naturally triggers a response without any prior learning, while a conditioned stimulus is initially neutral but becomes associated with the unconditioned stimulus through learning. In classical conditioning, the unconditioned stimulus elicits an unconditioned response, while the conditioned stimulus eventually elicits a conditioned response after being paired with the unconditioned stimulus.

What is the difference between a unconditioned response and a conditioned response?
An unconditioned response is automatic and unlearned, triggered by a specific stimulus. A conditioned response, on the other hand, is learned through association with a neutral stimulus that was previously paired with an unconditioned stimulus.
How do you Extinguish classically conditioned behavior?
You can extinguish classically conditioned behavior by repeatedly presenting the conditioned stimulus without the unconditioned stimulus until the conditioned response weakens and eventually disappears. This process is known as extinction. It is important to consistently withhold the unconditioned stimulus so that the association between the conditioned stimulus and the unconditioned stimulus is broken.
When can a conditioned response be extinguished?
A conditioned response can be extinguished through repeated presentation of the conditioned stimulus without the unconditioned stimulus. Over time, the association between the conditioned stimulus and the unconditioned stimulus weakens, leading to a decrease or disappearance of the conditioned response.
How are the strongest associations between the conditioned stimulus and the unconditioned stimulus formed?
The strongest associations between the conditioned stimulus and the unconditioned stimulus are formed through repeated pairings of the two stimuli. When the conditioned stimulus reliably predicts the unconditioned stimulus, learning occurs through classical conditioning. The more consistent and closely timed the pairings, the stronger the association becomes.
What will happen If a conditioned stimulus is repeated over and over without being paired with an unconditioned stimulus is repeated over and over without being paired with an unconditioned stimulus?
If a conditioned stimulus is repeated over and over without being paired with an unconditioned stimulus, the conditioned response will weaken and eventually extinguish through a process called extinction. The association between the conditioned stimulus and the unconditioned stimulus will weaken, leading to a loss of the learned response.
