Tokens can be in the form of fake money, buttons, poker chips, stickers, etc. While the rewards can range anywhere from snacks to privileges or activities.
For example, teachers use token economy at primary school by giving young children stickers to reward good behavior.
Token economy has been found to be very effective in managing psychiatric patients. However, the patients can become over reliant on the tokens, making it difficult for them to adjust to society once they leave prison, hospital, etc.
Staff implementing a token economy programme have a lot of power. It is important that staff do not favor or ignore certain individuals if the programme is to work. Therefore, staff need to be trained to give tokens fairly and consistently even when there are shift changes such as in prisons or in a psychiatric hospital.
A further important contribution made by Skinner is the notion of behavior shaping through successive approximation. Skinner argues that the principles of operant conditioning can be used to produce extremely complex behavior if rewards and punishments are delivered in such a way as to encourage move an organism closer and closer to the desired behavior each time.
To do this, the conditions or contingencies required to receive the reward should shift each time the organism moves a step closer to the desired behavior. According to Skinner, most animal and human behavior including language can be explained as a product of this type of successive approximation.
In the conventional learning situation, operant conditioning applies largely to issues of class and student management, rather than to learning content. It is very relevant to shaping skill performance. A simple way to shape behavior is to provide feedback on learner performance, e. A variable-ratio produces the highest response rate for students learning a new task, whereby initially reinforcement e.
For example, if a teacher wanted to encourage students to answer questions in class they should praise them for every attempt regardless of whether their answer is correct. Gradually the teacher will only praise the students when their answer is correct, and over time only exceptional answers will be praised. Unwanted behaviors, such as tardiness and dominating class discussion can be extinguished through being ignored by the teacher rather than being reinforced by having attention drawn to them.
Knowledge of success is also important as it motivates future learning. However, it is important to vary the type of reinforcement given so that the behavior is maintained. Skinner's study of behavior in rats was conducted under carefully controlled laboratory conditions.
Note that Skinner did not say that the rats learned to press a lever because they wanted food. He instead concentrated on describing the easily observed behavior that the rats acquired. In the Skinner study, because food followed a particular behavior the rats learned to repeat that behavior, e. Therefore research e.
Skinner proposed that the way humans learn behavior is much the same as the way the rats learned to press a lever. So, if your layperson's idea of psychology has always been of people in laboratories wearing white coats and watching hapless rats try to negotiate mazes in order to get to their dinner, then you are probably thinking of behavioral psychology. Behaviorism and its offshoots tend to be among the most scientific of the psychological perspectives.
The emphasis of behavioral psychology is on how we learn to behave in certain ways. We are all constantly learning new behaviors and how to modify our existing behavior. Operant conditioning can be used to explain a wide variety of behaviors, from the process of learning, to addiction and language acquisition.
It also has practical application such as token economy which can be applied in classrooms, prisons and psychiatric hospitals. However, operant conditioning fails to take into account the role of inherited and cognitive factors in learning, and thus is an incomplete explanation of the learning process in humans and animals. For example, Kohler found that primates often seem to solve problems in a flash of insight rather than be trial and error learning. Skinner was a behavioral psychologist who expanded the field by defining and elaborating on operant conditioning.
Research regarding this principle of learning was first conducted by Edward L. Thorndike in the late s, then brought to popularity by B. Skinner in the mids. Much of this research informs current practices in human behavior and interaction.
Skinner theorized that if a behavior is followed by reinforcement, that behavior is more likely to be repeated, but if it is followed by some sort of aversive stimuli or punishment, it is less likely to be repeated. He also believed that this learned association could end, or become extinct, if the reinforcement or punishment was removed.
Skinner : Skinner was responsible for defining the segment of behaviorism known as operant conditioning—a process by which an organism learns from its physical environment. In his first work with rats, Skinner would place the rats in a Skinner box with a lever attached to a feeding tube. Whenever a rat pressed the lever, food would be released.
After the experience of multiple trials, the rats learned the association between the lever and food and began to spend more of their time in the box procuring food than performing any other action.
It was through this early work that Skinner started to understand the effects of behavioral contingencies on actions. He discovered that the rate of response—as well as changes in response features—depended on what occurred after the behavior was performed, not before. Skinner named these actions operant behaviors because they operated on the environment to produce an outcome. The process by which one could arrange the contingencies of reinforcement responsible for producing a certain behavior then came to be called operant conditioning.
In this way, he discerned that the pigeon had fabricated a causal relationship between its actions and the presentation of reward. In his operant conditioning experiments, Skinner often used an approach called shaping. Instead of rewarding only the target, or desired, behavior, the process of shaping involves the reinforcement of successive approximations of the target behavior.
Behavioral approximations are behaviors that, over time, grow increasingly closer to the actual desired response. Skinner believed that all behavior is predetermined by past and present events in the objective world. He did not include room in his research for ideas such as free will or individual choice; instead, he posited that all behavior could be explained using learned, physical aspects of the world, including life history and evolution. His work remains extremely influential in the fields of psychology, behaviorism, and education.
Shaping is a method of operant conditioning by which successive approximations of a target behavior are reinforced. In his operant-conditioning experiments, Skinner often used an approach called shaping. The method requires that the subject perform behaviors that at first merely resemble the target behavior; through reinforcement, these behaviors are gradually changed, or shaped , to encourage the performance of the target behavior itself.
Shaping is useful because it is often unlikely that an organism will display anything but the simplest of behaviors spontaneously. It is a very useful tool for training animals, such as dogs, to perform difficult tasks. Dog show : Dog training often uses the shaping method of operant conditioning. In shaping, behaviors are broken down into many small, achievable steps.
To test this method, B. Skinner performed shaping experiments on rats, which he placed in an apparatus known as a Skinner box that monitored their behaviors.
The target behavior for the rat was to press a lever that would release food. Initially, rewards are given for even crude approximations of the target behavior—in other words, even taking a step in the right direction. Then, the trainer rewards a behavior that is one step closer, or one successive approximation nearer, to the target behavior.
For example, Skinner would reward the rat for taking a step toward the lever, for standing on its hind legs, and for touching the lever—all of which were successive approximations toward the target behavior of pressing the lever. As the subject moves through each behavior trial, rewards for old, less approximate behaviors are discontinued in order to encourage progress toward the desired behavior.
For example, once the rat had touched the lever, Skinner might stop rewarding it for simply taking a step toward the lever. In this way, shaping uses operant-conditioning principles to train a subject by rewarding proper behavior and discouraging improper behavior. This process has been replicated with other animals—including humans—and is now common practice in many training and teaching methods.
It is commonly used to train dogs to follow verbal commands or become house-broken: while puppies can rarely perform the target behavior automatically, they can be shaped toward this behavior by successively rewarding behaviors that come close.
