Burrhus Frederic Skinner
People do on a day to day basis, many actions without realizing it, and most of the time, they don’t know why they do them. Certain reinforcements, some positive, and some negative have conditioned their actions and thoughts. All organisms, including humans, are greatly influenced by the consequences produced by their own behavior. The environment holds the key to most of the changes that occur in the way a person behaves and a human’s own behavior brings consequences that change his or her actions (B. F. Skinner). Dr. B.F. Skinner forged the theory of Behaviorism, “a school of psychology that rejects the unobservable and focuses on patterns of responses to external rewards and stimuli” (Skinner, B. F.).

F. Skinner).
He got his masters in psychology in 1930 and his doctorate in 1931, and stayed there to do research until 1936. In 1945, Skinner became the chairman of the psychology department at Indiana University, and in 1948 he was invited to come back to Harvard to teach, which is where he spent the rest of his life.
B. F. never became the award winning novelist he originally dreamed of, but he does write a large amount of papers and books on behaviorism. He will be most remembered for Walden II, a book about a utopian society that is run on Skinner’s own operant principles. “He worked in the lab of an experimental biologist, and developed behavioral studies of rats. He loved building Rube Goldberg contraptions as a kid; he put that skill to use by designing boxes to automatically reward behavior, such as depressing a lever, pushing a button, and so on. His devices were such an improvement on the existing equipment, they've come to be known as Skinner boxes” (A Science Odyssey).
B. F. Skinner’s entire system is based on operant conditioning. “The organism is in the process of ‘operating’ on the environment, which in
In chapter 1, Opening Skinner’s Box, Slater talks about a psychologist named B. F. Skinner. Skinner shows us how easily operant conditioning can be done. He believed that you have a better outcome if you study observable behavior instead of studying mental events. Skinner’s work focused on operant conditioning. People and animals were the subjects of his studies.
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
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
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.
Psychologist, born in Susquhanna, Pa. He studied at Harvard, teaching there (1931-6, 1947-74). A leading behaviorist, he is a proponent of operant conditioning, and the inventor of the Skinner box for facilitating experimental observations.
B.F. Skinner’s theory of Operant Conditioning has at its foundation a desire to demonstrate a “cause and
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.
Just as Freud is known as the father of Psychoanalysis, B.F. Skinner is often referred to ask the “the father of operant conditioning.” B.F. Skinner is also known for major contributions to the field of psychology (About B.F. Skinner, Sept, 2012). Skinner was a prolific author, publishing nearly 200 articles and more than 20 books. Skinner was most known for his work in behavior psychology. Behavioral psychology is the psychological practice that focuses on learning new behaviors and how to modify our existing behavior and how that takes place (About B.F. Skinner, Sept, 2012). One of his major contributions was his theory of operant conditioning. Operant conditioning means roughly, the changing of behavior by the use of reinforcement, either positive or negative, and which these reinforcements are given after the desired response (About B.F. Skinner, Sept, 2012). Skinner identified three types of responses or operant that can follow behavior.
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).
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.
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
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.
According to Boeree, C, George (2006), B. F. Skinner’s “entire system is based on ‘operant conditioning’”. Behaviourism is determined by the environment and is “concerning with the effect of external events such as reward or punishment for behaviour” (Duschesne,
Burrhus Frederic Skinner was born on March 20, 1904 in Susquehanna, Pennsylvania. Skinner was an American psychologist, behaviorist, author, inventor, and a social philosopher. Skinner is known for his discovery of the theory of operant conditioning (Wikipedia). Skinner was a graduate from Harvard University. Although he understood the importance of classical conditioning, he noted that, “principles of classical conditioning account for only a small portion of learned behaviors” (Woolfolk 250). Skinner expressed that through operant conditioning, behavior is strengthened or weakened by antecedents or consequences. Both theorists’ work have a major influence on learning/behavioral concepts.
