Answer: waiting in an elevator is a good example of variable interval reinforcement schedule
Explanation:
Schedule of reinforment (an important component of learning process) is a rule that states the conditions of a response to be reinforced. The goal of reinforcement (either positive or negative) is to fortify a behaviour so that it will likely happen.
Variable interval reinforcement schedule happens when a response is rewarded after an unpredictable amount of responses has moved by. This kind of reinforcement produces slow and steady responses. An example is waiting in an elevator. One can decide to press the button once or fifteen times in succession, but the lift still appears randomly.
