Final answer:
Being paid every two weeks at a job is an example of a fixed interval reinforcement schedule, while slot machines operate on a variable ratio reinforcement schedule.
Step-by-step explanation:
Getting paid every two weeks at a job corresponds to a fixed interval reinforcement schedule. This is because the reinforcement (getting paid) is provided after a set amount of time, regardless of the number of responses or amount of work done in that timeframe.
Correspondingly, slot machines typically reward gamblers according to a variable ratio reinforcement schedule since this involves a reward being given after an unpredictable number of responses, which encourages high and steady response rates with little pause after reinforcement.
