Answer: Spontaneous recovery
Explanation:
A conditioned stimulus can be defined as the stimulus which can trigger the same response that can be created by a natural stimulus or unconditioned stimulus. It is a neutral stimulus that with a particular time and training evokes a response along with the naturally occurring stimulus.
The spontaneous recovery is a type of learning and conditioning process in which a specific response given by the organism reappears which was once extinguished. This recovery may happen when the conditioned stimulus is not exposed to the subject.
