In a variable interval schedule of reinforcement, behavior is reinforced after an unpredictable period of time has passed. For example, a rat might be rewarded with a food pellet for the first response after a random amount of time has elapsed. This reinforcement schedule leads to a slow and steady rate of response.
What is an example of reinforcement schedule?
These are examples of partial reinforcement:
- A dog is given a treat for every two minutes they remain in their place.
- A child is given a special dessert if they can stay seated during dinner.
- A boy is given a dollar every other time he picks up his room.
What are the 4 types of reinforcement schedules?
changing:time: Ex:slot machines, schedule of reinforcement requiring a varying number of responses for reinforcement. Fixed-interval Set:responses: Ex paid every friday. reinforcer given after a certain time has passed
What is an example of variable interval schedule?
What are the 4 types of reinforcement schedules?
- Fixed interval schedule (FI)
- Fixed ratio schedule (FR)
- Variable interval schedule (VI)
- Variable ratio schedule (VR)
What is fixed interval reinforcement schedule?
In operant conditioning, a fixed-interval schedule is a schedule of reinforcement 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.
What is a variable interval schedule?
Variable Interval Schedule. Interval schedules involve reinforcing a behavior after an variable interval of time has passed. In a variable interval schedule, the interval of time is not always the same but centers around some average length of time.
Which of the following is an example of variable interval?
Examples of interval variables include: temperature (Farenheit), temperature (Celcius), pH, SAT score (200-800), credit score (300-850).
What is a variable schedule of reinforcement?
Variable ratio reinforcement is one way to schedule reinforcements in order to increase the likelihood of conscious behaviors. The reinforcement, like the jackpot for a slot machine, is distributed only after a behavior is performed a certain number of times.
Which of the following is an example of a variable ratio schedule of reinforcement?
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.
What is the difference between variable interval and variable ratio?
Variable Intervals The difference between variable ratio and the variable interval schedule is that the rates of behaviors are low because it is based on the passage of a specific time period, and not the number of responses.
Is a variable an interval?
In the context of operant conditioning, variable means that a behavior is being reinforced on an inconsistent schedule. Interval refers to the passage of time between reinforcement.
What is an example of fixed interval schedule?
Fixed Interval Schedules in the Real World A weekly paycheck is a good example of a fixed-interval schedule. The employee receives reinforcement every seven days, which may result in a higher response rate as payday approaches. Dental exams also take place on a fixed-interval schedule.
What is a variable ratio schedule of reinforcement quizlet?
Variable ratio schedules of reinforcement: Provide high and steady rates of the behavior targeted for reinforcement. A limited hold is sometimes added to interval reinforcement in order to: Speed up the display of the target behavior.
What is an interval schedule of reinforcement based on?
Interval means the schedule is based on the time between reinforcements, and ratio means the schedule is based on the number of responses between reinforcements. Reinforcement is delivered at predictable time intervals (e.g., after 5, 10, 15, and 20 minutes).
What is an example of fixed ratio reinforcement?
For example, a fixed-ratio schedule might involve the delivery of a reward for every fifth response. After the subject responds to the stimulus five times, a reward is delivered. So, imagine that you are training a lab rat to press a button in order to receive a food pellet.
Which of the following is an example of continuous schedule of reinforcement?
An example of continuous reinforcement is a reward given to an animal every time they display a desired behavior. An example of partial reinforcement would be a child who is rewarded if they are able to keep their room clean for a period time and receives a reward.
Which of the following is an example of a variable?
A variable is a characteristic that can be measured and that can assume different values. Height, age, income, province or country of birth, grades obtained at school and type of housing are all examples of variables.
Is age a interval variable?
Is “age” considered an interval or ratio variable? The short answer: Age is considered a ratio variable because it has a “true zero” value.
What type of variable is time?
Continuous variable: a variable with infinite number of values, like “time” or “weight”.
What type of variable how Internet is used at home?
(*) Household size, monthly income and number of computers — these are quantitative variables. Income is a continuous variable. Household size and number of computers are discrete variables. (*) Occupation of head of household and type of internet connection are qualitative variables.
How does a variable interval schedule work?
How Does a Variable-Interval Schedule Work? To understand how a variable-interval schedule works, let's start by taking a closer look at the term itself. Schedule refers to the rate of reinforcement delivery, or how frequently the reinforcement is given. Variable indicates that this timing is not consistent and may vary from one trial to the next.
How often do pigeons get reinforcement?
This means that the pigeon will receive reinforcement an average of every 30 seconds. It is important to note that this is an average, however. Sometimes the pigeon might be reinforced after 10 seconds; sometimes it might have to wait 45 seconds. The key is that the timing is unpredictable.
How does operant conditioning work?
As you probably recall, operant conditioning can either strengthen or weaken behaviors through the use of reinforcement and punishment. This learning process involves forming an association with behavior and the consequences of that action. 2 . Psychologist B.F. Skinner is credited with the introduction of the concept of operant conditioning.
Who is credited with the concept of operant conditioning?
Psychologist B.F. Skinner is credited with the introduction of the concept of operant conditioning. He observed that reinforcement could be used to increase a behavior, and punishment could be used to weaken behavior.
What is variable ratio reinforcement?
A variable ratio reinforcement is just one option for people who want to increase the likelihood of someone else’s (or their own) behavior. Fixed ratio, fixed interval, and variable interval schedules are also available. If you want to learn more about these, keep a lookout for upcoming videos!
Why do kids throw temper tantrums?
Let’s say a child throws a temper tantrum at dinner because they don’t want to eat their vegetables. Most of the time, their parents wait out the tantrum and do not leave the table until the child eats their food. But every once and a while, when the parent is tired or frustrated, they “give in.”.
Is variable ratio reinforcement addictive?
Variable Ratio Reinforcement (Examples) Gambling can be fun, but it can also be addicting. Let’s say you win $10 the first time you hit the slots. The next time, you lose a dollar. The next time, you lose another dollar. Although both of those losses sting a little bit, you know that you’re bound to win again at some point.
Is gambling a form of reinforcement?
Gambling isn’t the only form of variable ratio reinforcement. Understanding this reinforcement schedule can also help you train a pet or train yourself to perform certain behaviors. In a lab, psychologists would study variable ratio reinforcement with animals.
Do all calls end in a rejection?
Not every call that you make is going to end in a deal. In fact, most calls will end in a rejection. But every once and a while, be it one in every 100 calls or even every 500 calls, you close a sale or receive an acceptance.
Continuous Schedules of Reinforcement
A continuous schedule of reinforcement involves reinforcing a behavior every time it occurs. Because this reinforcement occurs every time the behavior is displayed, the learner is able to form an association between the behavior and the consequence for that behavior quite quickly.
Partial Schedules of Reinforcement
Unlike continuous reinforcement, partial (or intermittent) schedules of reinforcement do not reinforce every instance of a behavior. Instead, reinforcement is given periodically. It might be delivered after a certain number of responses have occurred or after a certain amount of time has elapsed.
Choosing a Reinforcement Schedule
The right reinforcement schedule often depends on the situation and the type of learning taking place. When learning first begins, it is often best to start with a continuous reinforcement schedule. Once the desired response has been established, it is often a good idea to switch to a partial reinforcement schedule.
History of Reinforcement Schedules
Schedules of reinforcement were first described by the psychologist B. F. Skinner as part of his theory of learning known as operant conditioning. In operant conditioning, reinforcement and punishment are utilized to either increase or decrease the likelihood that a behavior will occur again in the future.
Study Questions
A weekly paycheck is an example of a fixed-interval schedule of reinforcement. Because the reinforcement arrives after a fixed period of time (every seven days), it may lead to a higher rate of responding as payday approaches, followed by a brief drop-off as soon as the reinforcement is delivered.
What Is a Fixed Interval Reinforcement?
Why are people so motivated to work when they only get paid every other week? This reinforcement model is called fixed interval reinforcement, meaning that reinforcement or rewards are given at a regular and fixed interval of time. In this case, every two weeks, the person receives the reward of a paycheck.
How a Fixed Interval Reinforcement Works
When a fixed interval reinforcement schedule is used, it is determined ahead of the practice time. It can be any interval of time from 1 minute to 1 day to 1 week, etc. But it is fixed and unchanging. This can have some benefits as well as some drawbacks.
Fixed Interval Example
Some examples of fixed-interval schedules have already been discussed. The bi-weekly paycheck and the first Tuesday of the month meeting. Here are some other examples:
Other Types of Reinforcements
There are two overall types of reinforcement: continuous reinforcement and partial schedule. There are 4 partial reinforcement schedules: fixed interval, fixed ratio, variable ratio, and variable interval.
What is schedule of reinforcement?
Introduction. A schedule of reinforcement is a component of operant conditioning (also known as ininstrumental conditioning). It consists of an arrangement to determine when to reinforce behavior. For example, whether to reinforce in relation to time or number of responses.
What is the difference between a continuous and partial reinforcement schedule?
In a continuous schedule every instance of a desired behavior is reinforced, whereas partial schedules only reinforce the desired behavior occasionally. Partial reinforcement schedules are described as either fixed or variable, and as either interval or ratio.
What is fixed interval conditioning?
In operant conditioning, a fixed interval schedule is when reinforcement is given to a desired response after specific (predictable) amount of time has passed. Such a schedule results in a tendency for organisms to increase the frequency of responses closer to the anticipated time of reinforcement.
Why does reinforcement occur every time?
In continuous schedules, reinforcement is provided every single time after the desired behavior. Due to the behavior reinforced every time, the association is easy to make and learning occurs quickly. However, this also means that extinction occurs quickly after reinforcement is no longer provided. For Example.
Who wrote the book Schedules of Reinforcement?
In 1957, a revolutionary book for the field of behavioral science was published: Schedules of Reinforcement by C.B. Ferster and B.F. Skinner. The book described that organisms could be reinforced on different schedules and that different schedules resulted in varied behavioral outcomes.
Is candy machine continuous reinforcement?
Candy machines are examples of continuous reinforcement because every time we put money in (behavior), we receive candy in return (positive reinforcement). However, if a candy machine were to fail to provide candy twice in a row, we would likely stop trying to put money in (Myers, 2011).

History of Reinforcement Schedules
- Imagine that you are training a pigeon to peck at a key to receive a food pellet. You put the bird on a variable-interval 30 (VI-30) schedule. This means that the pigeon will receive reinforcement an average of every 30 seconds. It is important to note that this is an average, however. Sometimes the pigeon might be reinforced after 10 seconds; some...
