Operant Conditioning by B. F Skinner

One famous behaviourist was Skinner (1904-1990) who was an American psychologist and believed in the role of reinforcement. There are two types of reinforcement: positive and negative. Positive reinforcement occurs when a particular behaviour is followed by a consequence that is desired such as receiving food, money or verbal praise. Whereas negative reinforcement takes place when a particular behaviour removes something unpleasant. Skinner used both positive and negative reinforcement in his experiment where he worked with rats and pigeons. He used a “Skinner box” to investigate the key values of learning new and challenging behaviours. Skinner used the theory of operant conditioning and would place the rat or pigeon into the “Skinner Box” the animal would then be curious and sniff and run around the box until eventually it would press the lever, which would release a food pellet. After a while the animal would carry out this behaviour many times, as it has learnt that after pressing the lever it will receive a food pellet as a consequence. As the pellet is experienced as reinforcing and something that the animal desires, this increases the chance of the behaviour being repeated. This is called

He removed the pellets as a reinforced and found that the rats would eventually stop pressing the lever. He also decided to reward the rats intermittently. He found that irregularly rewarded behavior was the hardest to eradicate. He was then able to explain why we do dumb things even when we are not consistently rewarded. Skinner’s experiments were amazing and disturbing at the same time.

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

Chapter 1 of Opening Skinners Box portrays the life and experiments of one B.F. Skinner. The way this one man researched and spent so many years of his life dedicated to his findings is not only crazy and committed, but encouraging, motivational, and stimulating. Skinner was a neo-behaviorist well-known and notorious for his findings about the behavior animals have when using positive reinforcement and what you can teach them to do with these findings.

Thereby, Skinner produced experiments whereby rats would navigate through mazes to achieve the goal of a box containing food. His interest was the behaviour of the rat, taking the right turn to achieve the desired result, food. To begin with the rats would take the wrong turn but with experience, they became more skilful. The rats learning behaviour was measured in two ways, firstly the length of time it took from start to end and secondly, the reduction in errors. This was a lengthy experiment which led Skinner to produce ‘the Skinner box’. Whereby, rats learnt to press a lever and pigeons learnt to peck a key in order to attain food, also known as behaviour shaping. This experiment lacks ecological validity as the animals are kept in a controlled environment which is dissimilar to their natural habitat. However, the results which were attained could not have been possible in natural circumstances. Skinner wanted to observe if behaviour could be learned through reaching a desired outcome such as positive reinforcement which needed to be

Skinner created the theory of Operant Conditioning as he believed that all behaviour can be controlled by rewards or reinforcement. This is very different from Pavlovs theory of Classical Conditioning as Skinner is trying to control voluntary behaviour. This is done by giving the subject a positive or negative reaction to an action with the theory that a negative response will discourage the subject to repeat the action. A good example of this is house training a dog, as the dogs natural reaction is to relieve itself, however it must be taught to wait until it is outside. The more the dog waits until he is outside, the more praise he receives therefore it is less likely to wish to instigate a negative reaction by relieving himself inside the house.

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.

Skinner’s theory observes individuals from the point of view of the behavior that they demonstrate. The key weakness of this theory is its attempt to explain the behaviors of an individual solely through visible phenomena. Critics sometimes accuse behaviorists of denying that ideas and thoughts exist (Jensen & Burgess, 1997). The major opposition that behaviorists face is that behavior of a person cannot be understood without including the mental activity of the individual. Critics have accused behaviorists of focusing only on behavior and ignoring the role of physiology, neuroscience, and genetics (Weiss & Rosales-Ruiz, 2014). Sometimes the reactions that people demonstrate have are not related their experience and therefore they have another

One of the most prominent and influential psychologists of the twentieth century, B.F. Skinner was known as a behavioral psychologist, philosopher of science, and an educational innovator. Throughout his life he did experimental work with animals to discover how patterns of behavior are learned. His initial work was primarily conducted with animals, and later in life he started to work with humans and apply his learning from his pigeon studies to human behavior. He focused on the individual and wrote about how to restructure social systems to improve the quality of life.

Skinner conducted a series of research experiments with rats and pigeons under controlled laboratory conditions using a specially designed cage. By doing so he sought to demonstrate that behaviour can be created and reinforced by external factors. The puzzle box he created for his experiments has become so widely used that it is now known as the “Skinner box”. Animals would be placed in a cage which had a bar lever mechanism used to dispense food; Skinner would measure the frequency of the bar pressing and introduce different variables into the experiments. This led to his discovery of 'partial reinforcement' and its correlation to the slower extinction of shaped behaviour. When food pellets would only be dispensed once in a while (as opposed to every pressing) Skinner noticed that it took longer for the learnt behaviour to become extinct. The powerful phenomenon of partial reinforcement can be noticed in gambling establishments; a player on a slot machine is more likely to keep up their behaviour of playing if the rewards are unpredictable and occasional. The player becomes more persistent in their gambling in the hope that the next coin will be the winner (Hunt, 1993).

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

     B.F. Skinner was one of the most influential theorists in modern psychology. His work was very important and has been studied by many for years. Skinner was a very straightforward man and a very educated man. His theories have helped mankind in many ways. He has studied the behavior patterns of many living organisms. Skinner was a well-published writer. His work has been published in many journals. He also has written many books on behaviorism. His most important work was the study of behaviorism.

While other psychologists believed that human psychology is a complex system because there are so many external influences, Skinner had believed that human’s mind is the same as other animals, which explains why he had done experiments using pigeons. Inspired by Watson and Pavlov, Skinner decided to study psychology and focused on behaviorism. Skinner’s theory was based on self-observation, which made him stood onto his believes regardless of the oppositions. In fact, during WW II, “Skinner convinced the military to fund his research--the famous Project Pigeon--to train pigeons to guide bombs and torpedoes.” (Greengrass, pg, 80) He chose pigeons because he thinks they live
