Final answer:
A problem behavior will be less resistant to extinction when it is reinforced on a fixed interval (FI) schedule prior to extinction.
Step-by-step explanation:
In operant conditioning, a problem behavior will be less resistant to extinction when it is reinforced on a fixed interval (FI) schedule prior to extinction. In a fixed interval schedule, behavior is rewarded after a set amount of time. For example, if June pushes a button for pain relief medication before the allotted time, no medication is administered because they are on a fixed interval reinforcement schedule. Extinction occurs quickly when reinforcement doesn't come at the expected time.
