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?

The association between the conditioned stimulus and the unconditioned stimulus will weaken, leading to a loss of the learned response.
