Final answer:
Napoleon's earning of $10 for every filled bucket of stray balls at the golf course is an example of a fixed ratio reinforcement schedule, as it involves a consistent reward after a set number of responses.
Step-by-step explanation:
When Napoleon works at the golf course and receives $10 for every bucket he fills with stray balls, he is experiencing a fixed ratio reinforcement schedule. This schedule applies because there is a set number of responses (buckets of balls) required before a reward (payment) is given. Unlike variable schedules which have unpredictable criteria, the fixed ratio schedule provides consistent reinforcement after a certain amount of work is completed.
