In 1933, Thorndike developed an explanation for his Law of Effect. His experimentations revealed that some events, usually those that one would expect to be pleasant seemed to “stamp in” a response that had just occurred. Noxious events, he continued, seemed to “stamp out” the response, or make it less likely to occur (Pierce and Cheney, 2004). Thus, the principles of reinforcement can be summarized as operants followed by consequences that increase or decrease the probability of response in the same situation (Pierce and Cheney, 2004). Based on the operant learning theories developed B.F. Skinner, Cooper, Heron and Heward (2007), define reinforcement as a process that occurs when a stimulus change immediately follows a response and increases the future frequency of that type of behavior in similar conditions. Thus, reinforcement is an operation which reinforces responses. Operant behavior is “selected, shared and maintained by the consequences that have followed in the past” (p. 31). In other words, our future is shaped by our past. Primary and Secondary Reinforcers In consideration of the history of reinforcement, the biological importance of primary reinforcers must be discussed. Food, water, oxygen and sexual stimulation may be considered as primary reinforcers because they satisfy contingencies of survival. No learning is necessary for these reinforcers to increase the likelihood of a response occurring again due to its presence or absence (Cooper, Heron and Heward,
Operant conditioning according to Walker et al (2007) pg 86 refers to learning that involves changes in voluntary responses those over which we normally have conscious control. Operant conditioning was developed largely by B.F. Skinner (1974,1989). According to Bastable (2003) pg 57 chap 3 operant conditioning focuses on the behaviour of the organism and reinforcement that occurs after the response. A reinforcer is a stimulus or event applied after a response that strengthens the probability that the response will be performed again. Skinner (1974) suggested that giving positive reinforcement i.e. (reward) greatly enhances behaviour and the likelihood that a response will be repeated in a similar circumstance. A second way to increase behaviour is by applying
Negative reinforcement is removing an unpleasant consequence when a behavior is exhibited in order to encourage said behavior. This was shown when
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
Reinforcement is the main contributing factor in operant conditioning. There is more than one way to go about establishing reinforcement, if a delay occurs between the response and the reinforcement the response may not become strengthened. It is likely that if the reinforcement occurs immediately after the response that there will be a definite strengthening of the response. Continuous reinforcement is when reinforcement occurs at every instance of the desired response. Intermittent reinforcement occurs when a response is reinforced some of the time. The different schedules of reinforcement influence patterns of response. Intermittent schedules offer greater resistance to extinction than continuous schedules.
Within the concept of operant conditioning, there are various simple schedules of reinforcement that are a part of our daily routine. Operant conditioning is a category of learning that invokes consequences, either negative or positive, as a way to increase or decrease behaviors (Powel, Honey & Symbaluk, 2013, p. 264) Schedules of reinforcement, such as fixed ratio, variable interval, fixed interval and variable ratio, are used as ways to strengthened or weaken those wanted or unwanted behaviors (Powel, Honey & Symbaluk, 2013, pp. 271-279). When applying these fundamental concepts to real world scenarios, it is crucial to first acknowledge which behavior is to be strengthened or weakened and then proceed with the conditioning.
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.
Operant conditioning is a theory that was pioneered by Skinner, and it is a theory that is based on the type of consequence that is given following a particular behaviour. Skinner divided the consequences of actions into three groups, positive rein forcers, negative reinforcers and punishers. Skinner looked at what would happen to behaviour if giving positive reinforcers at different intervals. Most professionals and practitioners will use this theory in one way or another such as giving rewards for good behaviour or sanctions for bad behaviour so the theory is well used in today’s frameworks and practices.
Operant conditioning has made a significant contribution into the development of psychology. However, as with most psychological theories, this theory it has its strengths and weaknesses. Nevertheless, operant conditioning, with both its positive and negative aspects, is very important in promoting learning of desirable behaviors or removal of undesirable
Skinner and his colleagues (Gass & Larry, 2008), learning or a change of behaviour on the part of the learner, is brought about by a process known as 'operant conditioning' which is the result of repeated training. Operant means 'voluntary behaviour' which is the result of learner's own free-will and is not forced by any outsider or thing (Ortega, 2009). The learner will demonstrate the new behaviour first as a response to a system of a reward or punishment, and finally it will become an automatic response.
Originally, reinforcement learning was motivated by “animal learning of sequential behavior, but has been developed and extended in the field of machine learning as an approach to Markov decision processes” (Ishii and Yoshida, 2006, p. 326). According to Andersen and Sandaker (2010), “A reinforcer is a stimulus which affects the probability of the kind of behaviour that produces it.? There can be both positive reinforcers and negative reinforcers. One where “behaviour that produces stimuli that reinforce consequences will increase.” The other is where “behaviour that produces these stimuli decreases or behaviour that removes them or postpones them increases.” Therefore, “many reinforcing stimuli are unconditional and function as reinforcers without prior learning. man is a
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.
Skinner believed that classical conditioning was limited to behaviors that are reflexively elicited. An operant describes behaviors that are "operate upon the environment to generate consequences." Reinforcement follows an operant and increases the likelihood of the operant being repeated.
