In real life, continuous reinforcement is rare. Sometimes responses are reinforced, sometimes not. Among the most important schedules of partial reinforcement are the fixed ration (FR), variable ration (VR), fixed Interval (FI), and variable interval (VI). Identify the schedule of reinforcement in each example below by writing your answer in the blank (FR, VR, FI, or VI)Explanation / Answer
There are four schedules of partial reinforcement:
Fixed-ratio schedules are those where a response is reinforced only after a specified number of responses. This schedule produces a high, steady rate of responding with only a brief pause after the delivery of the reinforcer. An example of a fixed-ratio schedule would be delivering a food pellet to a rat after it presses a bar five times.
Variable-ratio schedules occur when a response is reinforced after an unpredictable number of responses. This schedule creates a high steady rate of responding. Gambling and lottery games are good examples of a reward based on a variable ratio schedule. In a lab setting, this might involve delivering food pellets to a rat after one bar press, again after four bar presses, and a third pellet after two bar presses.
Fixed-interval schedules are those where the first response is rewarded only after a specified amount of time has elapsed. This schedule causes high amounts of responding near the end of the interval, but much slower responding immediately after the delivery of the reinforcer. An example of this in a lab setting would be reinforcing a rat with a lab pellet for the first bar press after a 30-second interval has elapsed.
Variable-interval schedules occur when a response is rewarded after an unpredictable amount of time has passed. This schedule produces a slow, steady rate of response. An example of this would be delivering a food pellet to a ?rat after the first bar press following a one-minute interval, another pellet for the first response following a five-minute interval, and a third food pellet for the first response following a three-minute interval.
1). Variable ratio schedule because buying lottery tickets is reinforced after unpredictable number of responses.
2). Fixed ratio schedule because maid is getting the reinforcement (15 minutes break) after a fixed number of responses (cleaning 3 rooms).
3). Variable interval schedule because the shooting stars occur after unpredictable time passed.
4). Fixed interval schedule because the teenager recieves allowance after a fixed 6 day time period.
5). Variable ratio schedule
6). Fixed ratio schedule as the number of hits is fixed.
7). Fixed interval schedule
8). Fixed ratio schedule because the number of response is fixed
9). Fixed ratio schedule because number of response is fixed (average 10 phone calls before reinforcement- donation is recieved)
10). Variable ratio schedule
11). Fixed ratio schedule
12). Variable interval schedule because the time of availability of next meal is not fixed.
