Spontaneous recovery in classical conditioning shows that the connection between a conditioned stimulus and response persists, leading to the reappearance of the response after a delay.
Spontaneous recovery is the phenomenon in classical conditioning where a conditioned response reappears after extinction with the passage of time. This indicates that the connection between a conditioned stimulus and conditioned response is not completely erased during extinction. For example, if a dog was conditioned to salivate at the sound of a bell but then stopped salivating after the bell was no longer followed by food, the salivation might reoccur after a period without exposure to the bell.
