By contrast, technical parlance would use the term "negative reinforcement" to describe encouragement of a given behavior by creating a scenario in which an unpleasant factor is or will be present but engaging in the behavior results in either escaping from that factor or preventing its occurrence, as in Martin Seligman 's experiments involving dogs' learning processes regarding the avoidance of electric shock.

Skinner was a well-known and influential researcher who articulated many of the theoretical constructs of reinforcement and behaviorism.

Skinner defined reinforcers according to the change in response strength response rate rather than to more subjective criteria, such as what is pleasurable or valuable to someone.

Accordingly, activities, foods or items considered pleasant or enjoyable may not necessarily be reinforcing because they produce no increase in the response preceding them.

Stimuli, settings, and activities only fit the definition of reinforcers if the behavior that immediately precedes the potential reinforcer increases in similar situations in the future; for example, a child who receives a cookie when he or she asks for one.

If the frequency of "cookie-requesting behavior" increases, the cookie can be seen as reinforcing "cookie-requesting behavior".

If however, "cookie-requesting behavior" does not increase the cookie cannot be considered reinforcing. The sole criterion that determines if a stimulus is reinforcing is the change in probability of a behavior after administration of that potential reinforcer.

Other theories may focus on additional factors such as whether the person expected a behavior to produce a given outcome, but in the behavioral theory, reinforcement is defined by an increased probability of a response.

The study of reinforcement has produced an enormous body of reproducible experimental results. Reinforcement is the central concept and procedure in special education , applied behavior analysis , and the experimental analysis of behavior and is a core concept in some medical and psychopharmacology models, particularly addiction , dependence , and compulsion.

Laboratory research on reinforcement is usually dated from the work of Edward Thorndike , known for his experiments with cats escaping from puzzle boxes.

Skinner, who published his seminal work on the topic in The Behavior of Organisms, in , and elaborated this research in many subsequent publications.

A great many researchers subsequently expanded our understanding of reinforcement and challenged some of Skinner's conclusions.

Research on the effects of positive reinforcement, negative reinforcement and punishment continue today as those concepts are fundamental to learning theory and apply to many practical applications of that theory.

The term operant conditioning was introduced by B. Skinner to indicate that in his experimental paradigm the organism is free to operate on the environment.

In this paradigm the experimenter cannot trigger the desirable response; the experimenter waits for the response to occur to be emitted by the organism and then a potential reinforcer is delivered.

In the classical conditioning paradigm the experimenter triggers elicits the desirable response by presenting a reflex eliciting stimulus, the Unconditional Stimulus UCS , which he pairs precedes with a neutral stimulus, the Conditional Stimulus CS.

Reinforcement is a basic term in operant conditioning. For the punishment aspect of operant conditioning — see punishment psychology. Positive reinforcement occurs when a desirable event or stimulus is presented as a consequence of a behavior and the behavior increases.

Negative reinforcement occurs when the rate of a behavior increases because an aversive event or stimulus is removed or prevented from happening.

Reinforcers serve to increase behaviors whereas punishers serve to decrease behaviors; thus, positive reinforcers are stimuli that the subject will work to attain, and negative reinforcers are stimuli that the subject will work to be rid of or to end.

A primary reinforcer , sometimes called an unconditioned reinforcer , is a stimulus that does not require pairing with a different stimulus in order to function as a reinforcer and most likely has obtained this function through the evolution and its role in species' survival.

Some primary reinforcers, such as certain drugs, may mimic the effects of other primary reinforcers. While these primary reinforcers are fairly stable through life and across individuals, the reinforcing value of different primary reinforcers varies due to multiple factors e.

Thus, one person may prefer one type of food while another avoids it. Or one person may eat lots of food while another eats very little.

So even though food is a primary reinforcer for both individuals, the value of food as a reinforcer differs between them. A secondary reinforcer , sometimes called a conditioned reinforcer , is a stimulus or situation that has acquired its function as a reinforcer after pairing with a stimulus that functions as a reinforcer.

This stimulus may be a primary reinforcer or another conditioned reinforcer such as money. An example of a secondary reinforcer would be the sound from a clicker, as used in clicker training.

The sound of the clicker has been associated with praise or treats, and subsequently, the sound of the clicker may function as a reinforcer.

Another common example is the sound of people clapping — there is nothing inherently positive about hearing that sound, but we have learned that it is associated with praise and rewards.

When trying to distinguish primary and secondary reinforcers in human examples, use the "caveman test. If, on the other hand, the caveman would not react to it e.

As with primary reinforcers, an organism can experience satiation and deprivation with secondary reinforcers. In his paper, Arbitrary and Natural Reinforcement , Charles Ferster proposed classifying reinforcement into events that increase frequency of an operant as a natural consequence of the behavior itself, and events that are presumed to affect frequency by their requirement of human mediation, such as in a token economy where subjects are "rewarded" for certain behavior with an arbitrary token of a negotiable value.

In , Baer and Wolf created a name for the use of natural reinforcers called "behavior traps". It is the use of a behavioral trap that increases a person's repertoire, by exposing them to the naturally occurring reinforcement of that behavior.

Behavior traps have four characteristics:. As can be seen from the above, artificial reinforcement is in fact created to build or develop skills, and to generalize, it is important that either a behavior trap is introduced to "capture" the skill and utilize naturally occurring reinforcement to maintain or increase it.

This behavior trap may simply be a social situation that will generally result from a specific behavior once it has met a certain criterion e.

Much behavior is not reinforced every time it is emitted, and the pattern of intermittent reinforcement strongly affects how fast an operant response is learned, what its rate is at any given time, and how long it continues when reinforcement ceases.

The simplest rules controlling reinforcement are continuous reinforcement, where every response is reinforced, and extinction, where no response is reinforced.

Between these extremes, more complex "schedules of reinforcement" specify the rules that determine how and when a response will be followed by a reinforcer.

Specific schedules of reinforcement reliably induce specific patterns of response, irrespective of the species being investigated including humans in some conditions.

However, the quantitative properties of behavior under a given schedule depend on the parameters of the schedule, and sometimes on other, non-schedule factors.

The orderliness and predictability of behavior under schedules of reinforcement was evidence for B.

Skinner 's claim that by using operant conditioning he could obtain "control over behavior", in a way that rendered the theoretical disputes of contemporary comparative psychology obsolete.

The reliability of schedule control supported the idea that a radical behaviorist experimental analysis of behavior could be the foundation for a psychology that did not refer to mental or cognitive processes.

The reliability of schedules also led to the development of applied behavior analysis as a means of controlling or altering behavior. Many of the simpler possibilities, and some of the more complex ones, were investigated at great length by Skinner using pigeons , but new schedules continue to be defined and investigated.

Simple schedules have a single rule to determine when a single type of reinforcer is delivered for a specific response. Simple schedules are utilized in many differential reinforcement [22] procedures:.

Compound schedules combine two or more different simple schedules in some way using the same reinforcer for the same behavior. There are many possibilities; among those most often used are:.

The psychology term superimposed schedules of reinforcement refers to a structure of rewards where two or more simple schedules of reinforcement operate simultaneously.

Reinforcers can be positive, negative, or both. An example is a person who comes home after a long day at work. The behavior of opening the front door is rewarded by a big kiss on the lips by the person's spouse and a rip in the pants from the family dog jumping enthusiastically.

Another example of superimposed schedules of reinforcement is a pigeon in an experimental cage pecking at a button.

The pecks deliver a hopper of grain every 20th peck, and access to water after every pecks. Superimposed schedules of reinforcement are a type of compound schedule that evolved from the initial work on simple schedules of reinforcement by B.

Skinner and his colleagues Skinner and Ferster, They demonstrated that reinforcers could be delivered on schedules, and further that organisms behaved differently under different schedules.

Rather than a reinforcer, such as food or water, being delivered every time as a consequence of some behavior, a reinforcer could be delivered after more than one instance of the behavior.

For example, a pigeon may be required to peck a button switch ten times before food appears. This is a "ratio schedule". Also, a reinforcer could be delivered after an interval of time passed following a target behavior.

An example is a rat that is given a food pellet immediately following the first response that occurs after two minutes has elapsed since the last lever press.

This is called an "interval schedule". In addition, ratio schedules can deliver reinforcement following fixed or variable number of behaviors by the individual organism.

Likewise, interval schedules can deliver reinforcement following fixed or variable intervals of time following a single response by the organism.

Individual behaviors tend to generate response rates that differ based upon how the reinforcement schedule is created. Much subsequent research in many labs examined the effects on behaviors of scheduling reinforcers.

If an organism is offered the opportunity to choose between or among two or more simple schedules of reinforcement at the same time, the reinforcement structure is called a "concurrent schedule of reinforcement".

Brechner , introduced the concept of superimposed schedules of reinforcement in an attempt to create a laboratory analogy of social traps , such as when humans overharvest their fisheries or tear down their rainforests.

Brechner created a situation where simple reinforcement schedules were superimposed upon each other. In other words, a single response or group of responses by an organism led to multiple consequences.

Concurrent schedules of reinforcement can be thought of as "or" schedules, and superimposed schedules of reinforcement can be thought of as "and" schedules.

Brechner and Linder and Brechner expanded the concept to describe how superimposed schedules and the social trap analogy could be used to analyze the way energy flows through systems.

Superimposed schedules of reinforcement have many real-world applications in addition to generating social traps. Many different human individual and social situations can be created by superimposing simple reinforcement schedules.

For example, a human being could have simultaneous tobacco and alcohol addictions. Even more complex situations can be created or simulated by superimposing two or more concurrent schedules.

For example, a high school senior could have a choice between going to Stanford University or UCLA, and at the same time have the choice of going into the Army or the Air Force, and simultaneously the choice of taking a job with an internet company or a job with a software company.

That is a reinforcement structure of three superimposed concurrent schedules of reinforcement. Superimposed schedules of reinforcement can create the three classic conflict situations approach—approach conflict, approach—avoidance conflict , and avoidance—avoidance conflict described by Kurt Lewin and can operationalize other Lewinian situations analyzed by his force field analysis.

Other examples of the use of superimposed schedules of reinforcement as an analytical tool are its application to the contingencies of rent control Brechner, and problem of toxic waste dumping in the Los Angeles County storm drain system Brechner, In operant conditioning , concurrent schedules of reinforcement are schedules of reinforcement that are simultaneously available to an animal subject or human participant, so that the subject or participant can respond on either schedule.

For example, in a two-alternative forced choice task, a pigeon in a Skinner box is faced with two pecking keys; pecking responses can be made on either, and food reinforcement might follow a peck on either.

The schedules of reinforcement arranged for pecks on the two keys can be different. They may be independent, or they may be linked so that behavior on one key affects the likelihood of reinforcement on the other.

It is not necessary for responses on the two schedules to be physically distinct. In an alternate way of arranging concurrent schedules, introduced by Findley in , both schedules are arranged on a single key or other response device, and the subject can respond on a second key to change between the schedules.

In such a "Findley concurrent" procedure, a stimulus e. Concurrent schedules often induce rapid alternation between the keys.

To prevent this, a "changeover delay" is commonly introduced: When both the concurrent schedules are variable intervals , a quantitative relationship known as the matching law is found between relative response rates in the two schedules and the relative reinforcement rates they deliver; this was first observed by R.

Animals and humans have a tendency to prefer choice in schedules. Shaping is reinforcement of successive approximations to a desired instrumental response.

In training a rat to press a lever, for example, simply turning toward the lever is reinforced at first.

Then, only turning and stepping toward it is reinforced. The outcomes of one set of behaviours starts the shaping process for the next set of behaviours, and the outcomes of that set prepares the shaping process for the next set, and so on.

As training progresses, the response reinforced becomes progressively more like the desired behavior; each subsequent behaviour becomes a closer approximation of the final behaviour.

Chaining involves linking discrete behaviors together in a series, such that each result of each behavior is both the reinforcement or consequence for the previous behavior, and the stimuli or antecedent for the next behavior.

There are many ways to teach chaining, such as forward chaining starting from the first behavior in the chain , backwards chaining starting from the last behavior and total task chaining in which the entire behavior is taught from beginning to end, rather than as a series of steps.

An example is opening a locked door. First the key is inserted, then turned, then the door opened. Forward chaining would teach the subject first to insert the key.

Once that task is mastered, they are told to insert the key, and taught to turn it. Once that task is mastered, they are told to perform the first two, then taught to open the door.

Backwards chaining would involve the teacher first inserting and turning the key, and the subject then being taught to open the door. Once that is learned, the teacher inserts the key, and the subject is taught to turn it, then opens the door as the next step.

Finally, the subject is taught to insert the key, and they turn and open the door. Once the first step is mastered, the entire task has been taught.

Total task chaining would involve teaching the entire task as a single series, prompting through all steps. Prompts are faded reduced at each step as they are mastered.

Persuasion is a form of human interaction. It takes place when one individual expects some particular response from one or more other individuals and deliberately sets out to secure the response through the use of communication.

The communicator must realize that different groups have different values. In instrumental learning situations, which involve operant behavior, the persuasive communicator will present his message and then wait for the receiver to make a correct response.

As soon as the receiver makes the response, the communicator will attempt to fix the response by some appropriate reward or reinforcement. In conditional learning situations, where there is respondent behavior, the communicator presents his message so as to elicit the response he wants from the receiver, and the stimulus that originally served to elicit the response then becomes the reinforcing or rewarding element in conditioning.

A lot of work has been done in building a mathematical model of reinforcement. This model is known as MPR, short for mathematical principles of reinforcement.

Peter Killeen has made key discoveries in the field with his research on pigeons. The standard definition of behavioral reinforcement has been criticized as circular , since it appears to argue that response strength is increased by reinforcement, and defines reinforcement as something that increases response strength i.

However, the correct usage [31] of reinforcement is that something is a reinforcer because of its effect on behavior, and not the other way around.

It becomes circular if one says that a particular stimulus strengthens behavior because it is a reinforcer, and does not explain why a stimulus is producing that effect on the behavior.

Other definitions have been proposed, such as F. Sheffield's "consummatory behavior contingent on a response", but these are not broadly used in psychology.

Increasingly understanding of the role reinforcers play is moving away from a "strengthening" effect to a "signalling" effect. While in most practical applications, the effect of any given reinforcer will be the same regardless of whether the reinforcer is signalling or strengthening, this approach helps to explain a number of behavioural phenomenon including patterns of responding on intermittent reinforcement schedules fixed interval scallops and the differential outcomes effect.

In the s Russian physiologist Ivan Pavlov may have been the first to use the word reinforcement with respect to behavior, but according to Dinsmoor he used its approximate Russian cognate sparingly, and even then it referred to strengthening an already-learned but weakening response.

He did not use it, as it is today, for selecting and strengthening new behaviors. Pavlov's introduction of the word extinction in Russian approximates today's psychological use.

In popular use, positive reinforcement is often used as a synonym for reward , with people not behavior thus being "reinforced", but this is contrary to the term's consistent technical usage, as it is a dimension of behavior, and not the person, which is strengthened.

Negative reinforcement is often used by laypeople and even social scientists outside psychology as a synonym for punishment.

This is contrary to modern technical use, but it was B. Skinner who first used it this way in his book. By , however, he followed others in thus employing the word punishment , and he re-cast negative reinforcement for the removal of aversive stimuli.

There are some within the field of behavior analysis [35] who have suggested that the terms "positive" and "negative" constitute an unnecessary distinction in discussing reinforcement as it is often unclear whether stimuli are being removed or presented.

For example, Iwata poses the question: Reinforcement and punishment are ubiquitous in human social interactions, and a great many applications of operant principles have been suggested and implemented.

Following are a few examples. Positive and negative reinforcement play central roles in the development and maintenance of addiction and drug dependence.

An addictive drug is intrinsically rewarding ; that is, it functions as a primary positive reinforcer of drug use. The brain's reward system assigns it incentive salience i.

For example, anti-drug agencies previously used posters with images of drug paraphernalia as an attempt to show the dangers of drug use.

However, such posters are no longer used because of the effects of incentive salience in causing relapse upon sight of the stimuli illustrated in the posters.

In drug dependent individuals, negative reinforcement occurs when a drug is self-administered in order to alleviate or "escape" the symptoms of physical dependence e.
