Final answer:
Jerry gets paid according to a fixed interval reinforcement schedule, whereas Joe gets paid according to a variable ratio reinforcement schedule.
Step-by-step explanation:
The difference between the way that Jerry gets paid and the way Joe gets paid is the difference between a fixed interval reinforcement schedule and a variable ratio reinforcement schedule. In a fixed interval reinforcement schedule, Jerry receives a regular paycheck at fixed time intervals, such as every week or every month. On the other hand, Joe is paid according to a variable ratio reinforcement schedule, where he is rewarded based on the number of items he produces, and the number of responses needed for a reward varies.
