answering questions correctly, the practitioner might “thin” the schedule of reinforcement by increasing the parameter of the ratio requirement to two responses (i.e., FR 2), thereby only providing reinforcement following every two correct responses.
What is reinforcement schedule thinning and how does it work?
Broadly speaking, reinforcement schedule thinning following FCT involves altering the reinforcement schedule, usually in a systematic and progressive manner across multiple sessions, until some terminal schedule, judged to be practical for care providers to implement, is reached.
What is an example of a reinforcement schedule?
For example, if you were to get a $500 bonus for every 10 sales you closed, you would be operating on a fixed-ratio reinforcement schedule. This schedule can be effective for learning new behaviors, but motivation tends to slow after the reinforcement is distributed.
What is the best way to thin the schedule?
One prevalent and effective means of schedule thinning involves the use of multiple schedules (Fisher et al., 2015;Greer et al., 2016).

What is schedule thinning in ABA?
Schedule thinning is a term used to describe a variety of techniques for decreasing, or. “thinning,” an existing schedule of reinforcement by gradually increasing the response ratio or. the duration of the time interval (Cooper, Heron, & Heward, 2007).

How do you give make the schedule of reinforcement?
Schedules of Reinforcement Examples You might start by giving the child a piece of candy every time they use the potty (fixed-ratio). Then, you may transition to only providing reinforcement after using the potty several days in a row (either fixed-interval or variable-interval).
What are the 4 types of reinforcement schedules?
Interval Schedule Combinations of these four descriptors yield four kinds of partial reinforcement schedules: fixed-ratio, fixed-interval, variable-ratio and variable-interval.
What is the best way to thin reinforcement?
Thinning of reinforcement involves a graduallincrease in the amount of appropriate responses required for reinforcement. Reinforcement should move from a thick reinforcement schedule (continuous) to a thinner reinforcement schedule (variable), and should be completed in a systematic manner to avoid ratio strain.
What is meant by reinforcement thinning?
Schedule thinning involves decreasing the rate or density of reinforcement until it meets the levels of reinforcement appropriate in the child's natural environment (Hagopian et al. 2011). Examples of thinning schedules of reinforcement following FCT include delay-to-reinforcement (e.g., Hanley et al.
Why is it important to thin schedules of reinforcement?
As noted by Tiger et al. and others, schedule thinning may be necessary when the newly acquired communication response occurs excessively, to the extent that reinforcing it consistently is not practical in the natural environment.
Which of the following schedules is thinnest?
Which of the following schedules is considered "thinnest"? the higher number is the "thinnest" ex: FR3 vs. VR4 (FR4, is the correct answer.
What is schedule reinforcement?
Schedules of reinforcement are the precise rules that are used to present (or to remove) reinforcers (or punishers) following a specified operant behavior. These rules are defined in terms of the time and/or the number of responses required in order to present (or to remove) a reinforcer (or a punisher).
What is the best type of reinforcement schedule?
Among the reinforcement schedules, variable ratio is the most productive and the most resistant to extinction. Fixed interval is the least productive and the easiest to extinguish (Figure 1).

What is schedule of reinforcement?
A schedule of reinforcement is basically a rule stating which instances of behavior will be reinforced. In some cases, a behavior might be reinforced every time it occurs. Sometimes, a behavior might not be reinforced at all.
Why is schedule of reinforcement important in operant conditioning?
When and how often we reinforce a behavior can have a dramatic impact on the strength and rate of the response.
What is fixed interval?
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 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.
Why do we need partial schedules?
Partial schedules reduce the risk of satiation once a behavior has been established. If a reward is given without end, the subject may stop performing the behavior if the reward is no longer wanted or needed. For example, imagine that you are trying to teach a dog to sit.
What is the process of learning new behaviors?
Operant conditioning is a learning process in which new behaviors are acquired and modified through their association with consequences. Reinforcing a behavior increases the likelihood it will occur again in the future while punishing a behavior decreases the likelihood that it will be repeated.
When is continuous reinforcement most effective?
Eventually, the dog will start to perform the action on its own. Continuous reinforcement schedules are most effective when trying to teach a new behavior. It denotes a pattern to which every narrowly-defined response is followed by a narrowly-defined consequence.
Is a continuous schedule good?
In cases where you are specifically trying to teach a new behavior, a continuous schedule is often a good choice. Once the behavior has been learned, switching to a partial schedule is often preferable. In daily life, partial schedules of reinforcement occur much more frequently than do continuous ones. For example, imagine if you received ...
What Is Reinforcement?
Behavioral psychologists in the early to mid-20th century identified punishments and reinforcements as a way to influence behavior through operant conditioning. Operant conditioning, unlike classical conditioning, could potentially lead a subject to consciously perform specific behaviors.
Continuous vs. Partial Reinforcement
Not every driver who is speeding gets caught because speed traps follow a partial reinforcement schedule. Partial reinforcement schedules only distribute reinforcements after a certain amount of time has gone by or a certain number of behaviors are performed.
Schedules of Reinforcement
The following are four schedules of reinforcement. All of them are easy to find in real life - you may be able to think of examples that you have unintentionally used to encourage your behavior one way or another. The four schedules of reinforcement are:
Which Reinforcement Schedule is Best?
Although continuous reinforcement is considered the best way to teach a new behavior quickly, partial reinforcement can work, too. Just think about gambling. Even if you are not a big gambler yourself, you may know someone who sits at the slot machines for hours, waiting for that jackpot to hit.
How to think of interval schedules of reinforcement?
A helpful way to think of the interval schedules of reinforcement (both fixed and variable) is to think of the chosen time period as a period of time where no reinforcement would be given for the target behaviour.
What is schedule of reinforcement?
A schedule of reinforcement is a protocol or set of rules that a teacher will follow when delivering reinforcers (e.g. tokens when using a token economy). The “rules” might state that reinforcement is given after every correct response to a question; or for every 2 correct responses; or for every 100 correct responses;
Why isn't reinforcement given after 2 minutes?
Just because he emitted the target behaviour (sitting upright) during the interval does not mean reinforcement is delivered at the end of the interval.
What is FI2 in a schedule?
A fixed-interval schedule means that reinforcement becomes available after a specific period of time. The schedule is abbreviated into “FI” followed by the amount of time that must pass before reinforcement becomes available, e.g. an FI2 would mean reinforcement becomes available after 2 minutes has passed; an FI20 means 20 minutes must pass and so on.
What is a fixed ratio schedule?
A fixed-ratio schedule of reinforcement means that reinforcement should be delivered after a constant or “fixed” number of correct responses. For example, a fixed ratio schedule of 2 means reinforcement is delivered after every 2 correct responses. The chosen number could be 5, 10, 20 or it could be 100 or more; there is no limit but the number must be defined.
When is reinforcement delivered?
Just like a fixed-interval (FI) schedule, reinforcement is only available to be delivered after the time interval has ended. Reinforcement is not delivered straight after the interval ends, the child must emit the target behaviour after the time interval has ended for the reinforcement to be delivered.
Is a thicker schedule than a FR10?
So a thicker schedule than an FR10 might be an FR5 schedule, so the child would now have to get only 5 correct responses before earning reinforcement. Sometimes the term “denser” schedule of reinforcement might be used to denote a thicker schedule – but these terms mean the same thing.
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).
What is schedule of reinforcement?
A schedule of reinforcement is a rule that describes how often the occurrence a behavior will receive a reinforcement. On the two ends of the spectrum of schedules of reinforcement there is continuous reinforcement (CRF) and extinction (EXT). Continuous reinforcement provides a reinforcement each and every time a behavior is emitted.
What is an INT schedule?
Intermittent schedules of reinforcement (INT) are when some, but not all, instances of a behavior are reinforced. An intermittent schedule of reinforcement can be described as either being a ratio or interval schedule. Ratio schedules are when a certain number of responses are emitted before reinforcement.
What is a variable schedule?
A variable schedule is when the number or time between reinforcements changes according to an average. Post-reinforcement pauses are associated with fixed schedules of reinforcement. While both fixed ratio and fixed interval show a post-reinforcement pause, the fixed ratio has a high steady rate.
What is schedule thinning?
Schedule thinning is an essential step in treating problem behavior, yet little research has been conducted to determine the method associated with sustained treatment effects. A frequently used method for thinning reinforcement is contingency‐based progressive delay, which requires the individual to meet some criteria before the reinforcers are returned. The response requirement could be dependent on (a) contextually appropriate behavior (differential reinforcement of alternative behavior‐based thinning) or (b) absence of problem behavior (differential reinforcement of other behavior‐based thinning). A translational arrangement with college students was implemented to determine the effects of these 2 response requirements. Tolerance was observed regardless of thinning method and was indicated by low rates of responding to the analogue problem behavior; however, more contextually appropriate behavior occurred during differential reinforcement of alternative behavior‐based thinning. These results support the use of response requirements for behaviors that are expected of the individual when reinforcement is not immediately forthcoming.
What is the most effective treatment for aggression and violence?
The most commonly prescribed behavioral intervention for aggression and violence exhibited by individuals with NDD is functional communication training (FCT). According to criteria for empirically supported treatments developed by Divisions 12 and 16 of the American Psychological Association, FCT is considered a “well-established” treatment for violence and aggression exhibited by children with NDD, and is characterized as “probably efficacious” with adults. In this chapter, we discuss variables related to the effectiveness of FCT as well as provide strategies for using FCT effectively in real-world settings, including teaching communication skills and programing for generalization of those skills. Furthermore, we discuss how FCT can be incorporated into a comprehensive behavioral treatment package for aggression and violence. Last, we identify limitations to communication-focused treatments, discuss methods to mitigate relapse of aggression and violence, and provide suggestions for areas of future research.
What is reinforcement thinning?
Thinning of reinforcement involves a graduallincrease in the amount of appropriate responses required for reinforcement. Reinforcement should move from a thick reinforcement schedule (continuous) to a thinner reinforcement schedule (variable), and should be completed in a systematic manner to avoid ratio strain.
What are the four types of partial reinforcement schedules?
There are four types of partial reinforcement schedules: fixed ratio, variable ratio, fixed interval and variable interval schedules. Fixed ratio schedules occur when a response is reinforced only after a specific number of responses.
How to change a contingency of reinforcement?
Changing a contingency of reinforcement by gradually increasing the response ratio or the extent of the time interval; it results in a lower rate of reinforcement per responses, time, or both.
What Is A Schedule of Reinforcement?
Continuous Schedules of Reinforcement
- In continuous reinforcement, the desired behavior is reinforced every single time it occurs.1This schedule is best used during the initial stages of learning to create a strong association between the behavior and response. Imagine, for example, that you are trying to teach a dog to shake your hand. During the initial stages of learning, you would stick to a continuous reinforcement schedu…
Partial Schedules of Reinforcement
- Once the response is firmly established, a continuous reinforcement schedule is usually switched to a partial reinforcement schedule.1 In partial (or intermittent) reinforcement, the response is reinforced only part of the time. Learned behaviors are acquired more slowly with partial reinforcement, but the response is more resistant to extinction. Think of the earlier example in w…
Schedules of Reinforcement and Extinction
- Once a reinforcement is stopped, the response starts to decline. This is referred to as extinction, or the length of time the response continues when the reinforcement is no longer applied. Typically, fixed schedules of reinforcement are more prone to extinction while variable schedules are more resistant. Extinction can result in undesirable side effects.2One is called a response bu…
Schedules of Reinforcement Examples
- Schedules of reinforcement can be applied in different settings. They can be used in education, for instance, such as by reinforcing students after a certain number of assignments have been completed or after going a certain amount of time without any behavioral issues. An example of using schedule of reinforcements in a parenting scenario is when potty training a child. You mig…
Using The Appropriate Schedule
- Deciding when to reinforce a behavior can depend on a number of factors. In cases where you are specifically trying to teach a new behavior, a continuous schedule is often a good choice. Once the behavior has been learned, switching to a partial schedule is often preferable. In daily life, partial schedules of reinforcement occur much more frequently than do continuous ones. For ex…
A Word from Verywell
- Operant conditioning can be a powerful learning tool. The schedules of reinforcement used during the training and maintenance process can have a major influence on how quickly a behavior is acquired, the strength of the response, and how frequently the behavior is displayed. In order to determine which schedule is preferable, consider different aspects of the situation, including th…
What Are Schedules of Reinforcement?
- Schedules of reinforcement describe different intervals and ratios in which reinforcements can be given out to encourage behavior through conditioning. All of them are easy to find in real life – you may be able to think of examples that you have unintentionally used to encourage behavior.
What Is Reinforcement?
- Behavioral psychologists in the early to mid-20th century identified punishments and reinforcements as a way to influence behavior through operant conditioning.

Why Are Schedules of Reinforcement Important?
- Habitsare hard to build. You want to wake up early, save money, or spend time studying instead of playing video games – but you don’t seem to have the motivation to do it on your own. When many people are stuck in this dilemma, they set up some sort of system that will increase the likelihood of them completing the habits (or behavior) that they want to complete. For some, thi…
Continuous vs. Partial Reinforcement
- Not every driver who is speeding gets caught because speed traps follow a partial reinforcement schedule. Partial reinforcement schedules only distribute reinforcements after a certain amount of time has gone by or a certain number of behaviors are performed. This is a direct contrast to continuous reinforcement, in which the behavior is reinforced every time it is performed. Continu…

Summary
Definition
- Broadly speaking there are two categories of reinforcement schedule, the first being a \"continuous\" schedule and the other being an \"intermittent\" schedule. A continuous schedule of reinforcement (sometimes abbreviated into CRF) occurs when reinforcement is delivered after every single target behaviour whereas an intermittent schedule of reinforcement (INT) means rei…
Applications
- Continuous reinforcement schedules are more often used when teaching new behaviours, while intermittent reinforcement schedules are used when maintaining previously learned behaviours (Cooper et al. 2007).
Example
- Within an educational setting, a CRF would mean that the teacher would deliver reinforcement after every correct response from their student/s. For example, if you were teaching a student to read the letters A, B, C, and D, then everytime you presented one of these letters to your student and they correctly read the letter then you would deliver reinforcement. For an everday example, …
Usage
- Generally, when writing out a fixed-ratio schedule into the discrete trial script it is shortened into just FR with the number of required correct responses stated after it (Malott & Trojan-Suarez, 2006). For example, choosing to reinforce for every second correct response would be written as FR2; reinforcing for every fifth correct response would be an FR5; for every 100 correct response…
Results
- Overall there were a total of 10 correct responses (1 + 3 + 2 + 1 + 3 = 10), reinforcement was delivered 5 times and so reinforcement was delivered for every 2 correct responses on average (10 ÷ 5 = 2). As can be seen in the image below, reinforcement did not follow a constant or fixed number of correct responses and instead varied and hence the name variable-ratio schedule of r…
Properties
- Both fixed-interval (FI) and variable-interval (VI) schedules of reinforcement might have what is called a limited hold placed on them. When a limited hold is applied to either interval schedule then reinforcement is only available for a set time period after the time intervals have ended.
Terminology
- Sometimes you might hear the term thicker schedule of reinforcement or thinner schedule of reinforcement. These terms are used to describe a change that may be made to a schedule of reinforcement already being used.
Variations
- There are also compound schedules of reinforcement where different types of reinforcement schedules are combined in various different ways. There is a lot that can be said to describe these schedules and for the sake of this article we will not go into this detail.
