For Skinner the use of so-called positive and negative reinforcements it was vital to modify both human and animal behavior; either to increase or enhance certain behaviors or to inhibit or eliminate them. Likewise, Skinner was interested in the practical applications of his theories; creating "programmed education".
3. Negative reinforcers. Skinner's reinforcement programs. 1. Continuous reinforcement. 2. Intermittent reinforcement. Criticisms of Skinner's theory. It seems obvious to think that, if after performing a certain behavior we receive an award or reward, it is much more likely that we will repeat it again.
Skinner differentiated between two types of reinforcers: positive reinforcers and negative reinforcers. 1. Positive reinforcers.
The reinforcement theory developed by Skinner, also known as operant conditioning or instrumental conditioning, attempts to explain human behavior in correspondence with the environment or the stimuli that surround it. Using the experimental method, Skinner comes to the conclusion that the appearance of a stimulus triggers a response in the person.
Skinner established that behavior is maintained from one context or situation to another as long as the consequences, that is, the reinforcers do not change or do so following certain logics, "rules" that must be discovered.
In turn, these positive reinforcers can be classified into the following categories: 1 Primary or intrinsic reinforcers: these are behaviors that by themselves generate satisfaction. For example eat if you are hungry. 2 Secondary reinforcers: they occur through learning and are external to the person. They can be material, like money or social, like recognition.
Finally, Skinner also gave rise to a series of essays surrounded by some controversy in which he proposed the use of psychological behavior modification techniques with the aim of de increase the quality of society and thus enhance people's happiness, as a kind of social engineering for the happiness and well-being of men and women.
Positive reinforcement is a method for behavior modification that increases the likelihood or probability that a behavior will occur. It strengthens a behavior by adding something pleasurable as a reward after the occurrence of the behavior.
A continuous reinforcement schedule is most effective for quickly learning and establishing a new behavior. However, there is also a higher extinction rate, which is the behavior ceasing when the reinforcement is no longer presented. It can also become impractical to use a continuous reinforcement rate for an extended period of time. After a behavior has been established, it is effective to move to an intermittent schedule of reinforcement.
Positive reinforcement is just one facet of B. F. Skinner's larger theory of operant conditioning. The operant conditioning model makes use of both rewards and punishments to transform behavior. In operant conditioning, the four types of consequences that shape behavior are positive reinforcements, negative reinforcements, positive punishments, and negative punishments. Positive reinforcements strengthen behavior by adding something pleasant; negative reinforcements do this by removing something unpleasant. Punishments, on the other hand, weaken behaviors or make them less likely to occur. Positive punishments add something unpleasant while negative punishments remove something pleasant. In order to illustrate and confirm his theories, B. F. Skinner conducted many experiments using pigeons and rats. He developed the Skinner box, which was equipped with a lever/key, electrical coils, and a food dispenser. Using electrical currents and food as reinforcements and punishments , Skinner was able to train the animals to push the lever or peck a key.
Positive reinforcements can be seen in many different daily scenarios, but can be hard to distinguish from other types of behavior consequences, such as punishments. To help with recognizing positive reinforcement, review the following examples.
Ratio reinforcement schedules are highly effective, motivating, and resistant to extinction--especially a ratio variable schedule. When speed and quantity of the behavior are the main concerns, then this can be the most effective method to utilize.
Responding because behavior has had reinforcing consequences is very different from responding by taking advice, following rules, or obeying laws . We do not take advice because of the particular consequence that will follow; we take it only when taking other advice from similar sources has already had reinforcing consequences. In general, we are much more strongly inclined to do things if they have had immediate reinforcing consequences than if we have been merely advised to do them.
It has long been known that behavior is affected by its consequences. We reward and punish people, for example, so that they will behave in different ways. A more specific effect of a consequence was first studied experimentally by Edward L. Thorndike in a well-known experiment. A cat enclosed in a box struggled to escape and eventually moved the latch which opened the door. When repeatedly enclosed in a box, the cat gradually ceased to do those things which had proved ineffective (“errors”) and eventually made the successful response very quickly.
This human species is distinguished by the fact that its vocal responses can be easily conditioned as operants. There are many kinds of verbal operants because the behavior must be reinforced only through the mediation of other people, and they do many different things. The reinforcing practices of a given culture compose what is called a language. The practices are responsible for most of the extraordinary achievements of the human species. Other species acquire behavior from each other through imitation and modelling (they show each other what to do), but they cannot tell each other what to do. We acquire most of our behavior with that kind of help. We take advice, heed warnings, observe rules, and obey laws, and our behavior then comes under the control of consequences which would otherwise not be effective. Most of our behavior is too complex to have occurred for the first time without such verbal help. By taking advice and following rules we acquire a much more extensive repertoire than would be possible through a solitary contact with the environment.
Other species acquire behavior from each other through imitation and modelling (they show each other what to do), but they cannot tell each other what to do. We acquire most of our behavior with that kind of help.
For example, students who are punished when they do not study may study, but they may also stay away from school (truancy), vandalize school property, attack teachers, or stubbornly do nothing. Redesigning school systems so that what students do is more often positively reinforced can make a great difference.
When one turns on the light, a response occurs, but that is not a reflex response. The lever can be pressed with different amounts of force, and if only strong responses are reinforced, the rat presses more and more forcefully. If only weak responses are reinforced, it eventually responds only very weakly.
To a hungry rat, food is a natural reinforcer, but the reinforcer in this example is the sound of the food dispenser, which was conditioned as a reinforcer when it was repeatedly followed by the delivery of food before the lever was pressed. In fact, the sound of that one operation of the dispenser would have had an observable effect even though no food was delivered on that occasion, but when food no longer follows pressing the lever, the rat eventually stops pressing. The behavior is said to have been extinguished.
Positive reinforcement is the act of rewarding a positive behavior in order to encourage it to happen again in the future, as in Getting an A on the test was the positive reinforcement I needed to continue studying.
The concept of positive reinforcement is credited to 20th-century behaviorism psychologist B. F. Skinner. As part of his work during the 1930s and 1940s, Skinner considered ways in which behavior could be changed by treating someone differently based on what they did. This idea is known as operant conditioning and is most often associated with Skinner’s theories. Positive reinforcement was one of four techniques that Skinner theorized could be used to alter behavior.
Many people are fans of positive reinforcement and respond best to this technique of behavior adjustment. Sometimes, people will even try to use it on themselves by only enjoying a reward if they accomplish a goal.
Positive Reinforcement. When a response is followed immediately by the presentation of a stimulus and, as a result, similar responses occur more frequently in the future. Positive Reinforcer. The stimulus presented as a consequence and responsible for the subsequent increase in responding.
The fact that a person does not have to understand or verbalize the relation between his actions and a reinforcing consequence, or for that matter even be aware that a consequence has occurred, for reinforcement to occur. Some behaviours produce their own reinforcement independent of the mediation of others.
A conditioned reinforcer that as a result of having been paired with many unconditioned and conditioned reinforcers does not depend on a current EO for any particular form of reinforcement for its effectiveness (e.g. social attention is a GCR for many people because it occurs simultaneously with many reinforcers)
Delivers a potential reinforcer whenever the target behaviour has not occurred during a set time interval. It allows for the continued presentation of the reinforcement contingency during the reversal phase of the control procedure
When stimuli are presented to the learner in a series of trials and the learner's response to the stimuli are recorded as an index of preference.
Multiple Stimuli: extension of paired-stimuli method. Is is when the learner chooses one stimuli out of a presentation of 3 or more stimuli at the same time. There are 2 variations:
