Skinner - Wikipedia, the free encyclopedia. Burrhus Frederic Skinner (March 2. Skinner, was an American psychologist, behaviorist, author, inventor, and social philosopher. If the consequences are bad, there is a high chance the action will not be repeated; if the consequences are good, the actions that led to it being repeated become more probable. ![]() To study operant conditioning he invented the operant conditioning chamber, also known as the Skinner Box. Using these tools, he and C. Ferster produced his most influential experimental work, which appeared in the book Schedules of Reinforcement. He imagined the application of his ideas to the design of a human community in his utopian novel, Walden Two. Watson and Ivan Pavlov. ![]() A June 2. 00. 2 survey listed Skinner as the most influential psychologist of the 2. Skinner and his wife Eve at Mount Auburn Cemetery. Skinner was born in Susquehanna, Pennsylvania, to Grace and William Skinner. His father was a lawyer. He became an atheist after a Christian teacher tried to assuage his fear of the hell that his grandmother described. He attended Hamilton College in New York with the intention of becoming a writer.

He found himself at a social disadvantage at Hamilton College because of his intellectual attitude. He wrote for the school paper, but, as an atheist, he was critical of the religious school he attended. After receiving his Bachelor of Arts in English literature in 1. Harvard University, where he would later research, teach, and eventually become a prestigious board member. While he was at Harvard, a fellow student, Fred Keller, convinced Skinner that he could make an experimental science from the study of behavior. This led Skinner to invent his prototype for the Skinner Box and to join Keller in the creation of other tools for small experiments. His encounter with John B. Watson's Behaviorism led him into graduate study in psychology and to the development of his own version of behaviorism. He then taught at the University of Minnesota at Minneapolis and later at Indiana University, where he was chair of the psychology department from 1. He remained at Harvard for the rest of his life. In 1. 97. 3, Skinner was one of the signers of the Humanist Manifesto II. The couple had two daughters, Julie (m. Vargas) and Deborah (m. Just a few days before his death, he was given a lifetime achievement award by the American Psychological Association, and delivered a 1. He has been widely revered for bringing a much- needed scientific approach to the study of human behavior; he has also been vilified for attempting to apply findings based largely on animal experiments to human behavior in real- life settings. Contributions to psychological theory. In contrast to the approach of cognitive science, behaviorism does not accept private events such as thinking, perceptions, and unobservable emotions as causes of an organism's behavior. ![]() However, in contrast to methodological behaviorism, Skinner's radical behaviorism did accept thoughts, emotions, and other . In his words: The position can be stated as follows: what is felt or introspectively observed is not some nonphysical world of consciousness, mind, or mental life but the observer's own body. This does not mean, as I shall show later, that introspection is a kind of psychological research, nor does it mean (and this is the heart of the argument) that what are felt or introspectively observed are the causes of the behavior. An organism behaves as it does because of its current structure, but most of this is out of reach of introspection. At the moment we must content ourselves, as the methodological behaviorist insists, with a person's genetic and environment histories. What are introspectively observed are certain collateral products of those histories.. When what a person does . Why explain the explanation? For twenty five hundred years people have been preoccupied with feelings and mental life, but only recently has any interest been shown in a more precise analysis of the role of the environment. Ignorance of that role led in the first place to mental fictions, and it has been perpetuated by the explanatory practices to which they gave rise.
He distinguished two sorts of behavior. Respondent behaviors are elicited by stimuli, and may be modified through respondent conditioning, which is often called . Operant behaviors, in contrast, are . They are strengthened through operant conditioning, sometimes called . Respondent behaviors might be measured by their latency or strength, operant behaviors by their rate. Both of these sorts of behavior had already been studied experimentally, for example, respondents by Pavlov. Among the most important are these: (1) Operant responses are strengthened by reinforcement, but where do they come from in the first place? Similarly, the behavior of an individual varies from moment to moment; a variation that is followed by reinforcement is strengthened and becomes prominent in that individual's behavioral repertoire. As discussed later in this article, Skinner believed that . Beyond Freedom and Dignity B. Skinner “Each of us,” . In Beyond Freedom and Dignity, Skinner suggests that a technology of behavior could. Skinner: A Life; Dews, P. Skinner's technology of behavior from. Skinner answered this question by saying that a stimulus comes to control an operant if it is present when the response is reinforced and absent when it is not. For example, if lever- pressing only brings food when a light is on, a rat, or a child, will learn to press the lever only when the light is on. Skinner summarized this relationship by saying that a discriminative stimulus (e. Some complex behavior can be seen as a sequence of relatively simple responses, and here Skinner invoked the idea of . That is, a discriminative stimulus is also a . This results in the sequence . To account for such behavior, Skinner introduced the concept of rule- governed behavior. First, relatively simple behaviors come under the control of verbal stimuli: the child learns to . After a large number of responses come under such verbal control, a sequence of verbal stimuli can evoke an almost unlimited variety of complex responses. Subsequently, in Science and Human Behavior (1. Skinner redefined negative reinforcement. In what has now become the standard set of definitions, positive reinforcement is the strengthening of behavior by the occurrence of some event (e. Both types of reinforcement strengthen behavior, or increase the probability of a behavior reoccurring; the difference is in whether the reinforcing event is something applied (positive reinforcement) or something removed or avoided (negative reinforcement). Punishment is the application of an aversive stimulus/event (positive punishment or punishment by contingent stimulation) or the removal of a desirable stimulus (negative punishment or punishment by contingent withdrawal). Though punishment is often used to suppress behavior, Skinner argued that this suppression is temporary and has a number of other, often unwanted, consequences. Ferster, he did an extensive analysis of the various ways in which reinforcements could be arranged over time, which he called . All are methods used in operant conditioning. Continuous reinforcement (CRF) . This method is effective when teaching a new behavior because it quickly establishes an association between the target behavior and the reinforcer. This schedule yields a response rate that is low just after reinforcement and becomes rapid just before the next reinforcement is scheduled. ![]() Variable Interval Schedule (VI): A procedure in which behaviour is reinforced after random time durations following the last reinforcement. This schedule yields steady responding at a rate that varies with the average frequency of reinforcement. Ratio Schedules . The lower the number of responses required, the higher the response rate tends to be. Ratio schedules tend to produce very rapid responding, often with breaks of no responding just after reinforcement if a large number of responses is required for reinforcement. It was invented by Skinner while he was a graduate student at Harvard University. As used by Skinner, the box had a lever (for rats), or a disk in one wall (for pigeons). By controlling this reinforcement together with discriminative stimuli such as lights and tones, or punishments such as electric shocks, experimenters have used the operant box to study a wide variety of topics, including schedules of reinforcement, discriminative control, delayed response (. By channeling research in these directions, the operant conditioning chamber has had a huge influence on course of research in animal learning and its applications. It enabled great progress on problems that could be studied by measuring the rate, probability, or force of a simple, repeatable response. However, it discouraged the study of behavioral processes not easily conceptualized in such terms. Skinner designed it for use with the Operant chamber as a convenient way to record and view the rate of responses such as a lever press or a key peck. In this device, a sheet of paper gradually unrolls over a cylinder. Each response steps a small pen across the paper, starting at one edge; when the pen reaches the other edge, it quickly resets to the initial side. The slope of the resulting ink line graphically displays the rate of the response; for example, rapid responses yield a steeply sloping line on the paper, slow responding yields a line of low slope. The cumulative recorder was a key tool used by Skinner in his analysis of behavior, and it was very widely adopted by other experimenters, gradually falling out of use with the advent of the laboratory computer. Ferster, Schedules of Reinforcement, is full of cumulative records produced by this device. It was designed to make early childcare simpler (by reducing laundry, diaper rash, cradle cap, etc.), while allowing the baby to be more mobile and comfortable, and less prone to cry. Reportedly it had some success in these goals. It was popularly mischaracterized as a cruel pen, and it was often compared to Skinner's operant conditioning chamber, commonly called the .
