Answer:
Extinction
Step-by-step explanation:
Extinction: The term extinction is defined as the moderate weakening of a specific conditioned response that gives rise to the disappearing behavior. Hence, the conditioned behavior will stop gradually.
In other words, if a particular behavior is not being reinforced continuously then there the behavior will disappear. It can occur in most of the behavioral conditioning techniques, but majorly in operant conditioning.
In the question above, Shana’s performance problems are mostly contributed by extinction.
