Final answer:
Extinction is the phenomenon where a learned behavior is forgotten after the conditioned stimulus is no longer associated with the unconditioned stimulus, which leads to the conditioned response fading away.
Step-by-step explanation:
The phenomenon where a learned behavior is forgotten if it stops eliciting the expected response is referred to as extinction. This occurs when the conditioned stimulus is no longer paired with the unconditioned stimulus, leading to a decrease and eventual disappearance of the conditioned response. Pavlov's experiments with dogs and the conditioning of their salivary responses to a bell are classic examples of extinction.
In the case of Tiger, the cat, if the electric can opener (conditioned stimulus) ceased being associated with her food (unconditioned stimulus) for an extended period, her behavior of running to the kitchen would likely undergo extinction. However, if the can opener were to be associated with feeding once again, or if the sound were heard after a rest period, the behavior could show spontaneous recovery, where the previously extinguished response returns.
