Skinners Operant Conditioning Theory
B.F Skinner (1904-1990), an American psychologist who was the leading exponent of the school of psychology know as behaviourism, maintained the idea that learning is a result of any change in overt behaviour. Changes in behaviour are determined by the way an individual responds to events (stimuli) in the environment. Skinner described this phenomenon as operant conditioning. Action on part of the learner is called a response. When a desired stimulus-response pattern is reinforced (rewarded), the individual is conditioned to respond in a certain way, and learning takes place. Reinforcement is a vital element in Skinner's Stimulus-Response Theory. A reinforcer is

Skinner proposes two types of reinforcement that increase the likelihood of a response occurring: positive, and negative. Positive reinforcement (reward) involves a positive consequence of behaviour. In contrast, a negative reinforcement (Relief) involves a behaviour that results in the elimination or prevention of a negative outcome. (Lefrancois, 1995).
Punishment
Like reinforcement, punishment can also determine the probability of whether behaviour will occur again. There are two types of punishment. One can be termed negative punishment, and involves the cessation of a positive event as a result of responding (Kentridge, 1995). For example, a reprimanded for bad behaviour. The other can be termed punishment, and involves a negative or aversive event in relation to responding (Kentridge, 1995). For example, receiving a fine for exceeding the speed limit. Punishment tends to suppress behaviour rather than strengthen.
Reinforcement Schedules
Studies of Reinforcement Schedules identify the various ways in which the environment makes reinforcement determine how we behave. There are four basic schedules that produce different response patterns: Fixed-Ratio (FR)
Skinner 's theory of operant conditioning was based on the work of Thorndike that he reviewed (1948). Edward Thorndike studied learning in animals using a puzzle box to propose the theory known as the 'Law of Effect ', responses that produce a satisfying effect in a situation become more likely to occur again in that situation, and responses that produce a discomforting effect become less likely to occur again in that situation. Skinner introduced a new term to Thorndike’s theory known as reinforcement (Skinner, 1948). Reinforcement is a stimulus (as a reward or the removal of an electric shock) that increases the probability of a desired response in operant conditioning by being applied or affected following the desired response. Skinner branched off Thorndike’s approach studied operant conditioning by experimenting on animals using conditioning chambers also known as a Skinner box and in 1948
According to Kail and Cavanaugh the theory established by Skinner known as operant conditioning is a “learning paradigm in which the consequences of a behavior determine whether a behavior is repeated in the future” (p. 13). This theory to an extent, parallels the previous theory of operant conditioning but is also important in trying to understand why one makes the decisions they do as well as how often they partake in certain behaviors. Through his theory Skinner displayed that there are two types of consequences, reinforcement and punishment, in which one increases the chances of repeated behavior and the other vice versa. Reinforcement is the component that increases the likeliness of repeated behavior and includes two divisions, negative and positive. Negative reinforcement is that in which a person’s
Operant Conditioning Theory by B.F. Skinner is a psychological manipulation using rewards and punishments to enforce positive behavior. It uses an individual person’s response to events or stimulus. When a particular Stimulus-Response pattern is rewarded, the individual is conditioned to respond. The distinctive characteristic of operant conditioning is related to previous forms of behaviorism. The Operant Conditioning theory comprises of neutral operants, positive/negative reinforcers, and positive/negative punishers. Through these factors, we get the desired behavior of our subject because they do not want to be punished for under performing so they do what they’re told to or do more of what they were assigned to to receive positive stimulus
A fundamental tenet of Skinner's radical behaviorism is that the probability of a behavior is related directly to the nature of the environmental consequences that follow performance of that behavior. From this basic tenet he derived a set of procedures for modifying behavior by a method called operant conditioning. Specifically, behavior is strengthened, or increased in frequency, when followed by either a positive consequence (positive reinforcement) or removal of a negative consequence (negative reinforcement). Behavior is weakened, or decreased
Skinner’s reinforcement experiments conducted on rats showed the principles of operant conditioning. While working with rats, Skinner would place them in a Skinner box with a lever attached to a feeding tube. After multiple trials, rats learned the connection between the lever and food, and started to spend more time in the box procuring food than performing any other action. He used positive reinforcement, and negative reinforcement to produce or inhibit specific target behaviors. Therefore, if a specific behavior is reinforced then the probability of that behavior occurring again is increased. Based on Skinner’s view, this theory can be applied to learning because learning is nothing more than a change in behavior. Operant conditioning encourages positive reinforcement, which can be applied in the classroom environment to get the good behavior you want and need from students. One of the ways of reinforcing a student’s behavior is through praise. Also teachers can build operant conditioning techniques into their lesson plans to teach children possible skills as well as good behaviors. For example: to give a smiley face, or motivational stamps to encourage children to perform correctly and encourage them to repeat such action again.
In this paper there will be an examination of the Operant Conditioning theory. It will describe the theory, and compare and contrast the positive and negative reinforcement. It will determine which form of reinforcement is the most effective, and will give an explanation of the reasoning behind that choice. It will also give a scenario in which operant conditioning is applied and how it shapes behavior. It will show a schedule that could be used in the reinforcement of the selected behavior in the scenario.
A researcher named Burrhus Frederic Skinner thought he would develop the idea of operant conditioning. He suggested than we act in regard to consequences (reward or punishment) in which we actively learn. He suggested there are 3 types of these consequences of behavior; positive reinforcement, negative reinforcement and punishment. Positive reinforcement is receiving a reward for acting in a certain way. An example of this could be getting a school prize for performing well in your exams, because of the reinforcement of the prize, the student will try to perform well every time. Negative reinforcement occurs when we act in a way that avoids an unpleasant consequence (e.g. not being late to a meeting because you do not want to be perceived as rude). Punishment is an unpleasant consequence that comes from the way we act. For example, gaining a detention for arriving late to lessons. Punishment decreases like probability that behaviour is likely to be repeated. Whereas, in positive and negative reinforcement the chances are you will repeat the behaviour. Skinner’s conducted research in the form of a lab experiment. He used a hungry rat that was placed in a cage that had been especially developed for the purpose of the study and was named Skinner’s box. In the cage was a button and a food dispenser. When the rat pressed the button food would appear in the dispenser. The animal soon learned that
This theory also heavily discusses the importance of positive and negative punishment and positive and negative reinforcement. Positive is when something is added and negative is when something is taken away. Positive punishment is when something is added in order to decrease an undesired behavior and negative punishment is when something is removed in order to decrease and undesired behavior. Positive reinforcement is
According to Gewirtz and Peláez-Nogueras (1992), “B. F. Skinner contributed a great deal to advancing an understanding of basic psychological processes and to the applications of science-based interventions to problems of individual and social importance.” He contributed to “human and nonhuman behavior, including human behavioral development, and to various segments of the life span, including human infancy” (p. 1411). One of Skinner's greatest scientific discoveries was “single reinforcement” which became sufficient for “operant conditioning, the role of extinction in the discovery of intermittent schedules, the development of the method of shaping by successive approximation, and Skinner's break with and rejection of stimulus-response
Punishment refers to a response with an unpleasant consequence. Punishment unlike reinforcement decreases the likelihood that the response will occur again. Positive punishment is any stimulus that, when added to a situation decreases the probability that a given behavior will occur. If a child is destroying the house by painting the walls and the parent catches them doing this act. The parent may spank the child adding an unpleasant consequence and hoping this behavior will not occur again.
Operant conditioning focuses on a system of reinforcement and punishers where actions will have a consequence (Skinner, 2016). In operant conditioning, behaviour that is reinforced will be strengthened while behaviour that is not reinforced will weaken with time (Skinner, 2016). There are three types of operants. The neutral operants that will neither increase nor decrease the chances of repeating a behaviour (Skinner, 2016). The reinforcers will increase the chances of repeating a behaviour (Skinner, 2016). The punishers will decrease the chances of repeating a behaviour (Skinner, 2016). Positive reinforcement strengthens a behaviour as an individual gains rewards through it (Skinner, 2016). Negative reinforcement strengthens the behaviour by removing an unpleasant consequence
Operant conditioning developed by Skinner is one of the learning methods according to which the likelihood of behavior is increased or decreased by the use of reinforcement or punishment. In case of positive reinforcement a certain behavior becomes stronger by the effect of experiencing some positive condition. In case of negative reinforcement a certain behavior becomes stronger by the outcome of stopping or staying away from some negative condition. In case of extinction a certain behavior is becomes weaker by the outcome of avoiding to experiencing some positive condition or stopping some negative condition.
In the field of child development, many psychologists, sociologists, and behaviorists contributed and came up with different theories that helped to form our current education system. One of those is B.F. Skinner’s theory of behaviorism, which had a great impact on many strategies we use today for teaching and training. In his theory, operant conditioning is the most famous and influential idea that helped people to understand the behaviors of children and even adults. Skinner focused on how the environments, in the form of reinforcement and punishments, influence behaviors. Thus, his theory cannot explain the higher cognitive functions such as problem solving and critical thinking. Despite his theory’s critiques, Skinner stood strong on his ideas and theories.
There are two forms of reinforcement: positive and negative reinforcement. When an event occurs producing a positive effect, it is considered positive reinforcement. Negative reinforcement involves the removal of a stimulus increasing the likelihood of a positive effect. An example of this would be to take two aspirins to remove the pain from a headache.
Skinner’s positive reinforcement starts by promoting good behavior in the classroom through the promise of a reward. Skinner created a rewards system that is said to help shape human behavior in a
