Question

directions: identify the schedule of reinforcement as fixed ratio (fr), variable ratio (vr), fixed interval (fi), or variable interval (vi). ex: catching the bus → fi 1. getting paid every week 2. winning a scratch off ticket 3. frequent flyer program; getting a free flight after accumulating 500 miles 4. legacy options terms ending every 7 weeks 5. random drug testing at your job 6. number of “throws” to get a strike in bowling 7. doing 50 sit - ups to keep fit 8. athletes signing a contract in which their salary increases every three years 9. when going easter egg hunting, finding an egg with a good prize in it 10. going up a staircase, you must go up the same number of stairs to get to the landing

Explanation:

1. Getting paid every week is a fixed - time interval, so it's Fixed Interval (FI).
2. Winning a scratch - off ticket is random in terms of when it happens, so it's Variable Ratio (VR).
3. Getting a free flight after accumulating 500 miles is a fixed number of miles (ratio), so it's Fixed Ratio (FR).
4. Legacy Options terms ending every 7 weeks is a fixed time interval, so it's Fixed Interval (FI).
5. Random drug testing is unpredictable in terms of time, so it's Variable Interval (VI).
6. The number of "throws" to get a strike in bowling is variable, so it's Variable Ratio (VR).
7. Doing 50 sit - ups is a fixed number (ratio) for a reward (fitness), so it's Fixed Ratio (FR).
8. Athletes' salary increasing every three years is a fixed time interval, so it's Fixed Interval (FI).
9. Finding an egg with a good prize in Easter egg hunting is random, so it's Variable Ratio (VR).
10. Going up a fixed number of stairs to get to the landing is a fixed ratio, so it's Fixed Ratio (FR).
