Baby in a Skinner Box. Obedience training/behaviour modification of toddlers. 1960s psychology study

After finishing his doctorate degree and working as a researcher at Harvard, Skinner published the results of his operant conditioning experiments in The Behavior of Organisms His work drew comparisons to Ivan Pavlov, but Skinner's work involved learned responses to an environment rather than involuntary responses to stimuli. This project was canceled, but he was able to teach them how to play ping pong. Skinner turned to a more domestic endeavor during the war. In , he built a new type of crib for his second daughter Deborah at his wife's request. The couple already had a daughter named Julie.

This clear box, called the "baby tender," was heated so that the baby didn't need blankets. There were no slats in the sides either, which also prevented possible injury. In , Skinner became the chair of the psychology department at Indiana University. But he left two years later to return to Harvard as a lecturer. Skinner received a professorship there in where he remained for the rest of his career. As his children grew, he became interested in education. Skinner developed a teaching machine to study learning in children. He later wrote The Technology of Teaching Skinner presented a fictional interpretation of some of his views in the novel Walden Two , which proposed a type of utopian society.

The people in the society were led to be good citizens through behavior modification—a system of rewards and punishments. The novel seemed to undermine Skinner's credibility with some of his academic colleagues. Others questioned his focus on scientific approaches to the exclusion of less tangible aspects of human existence. In the late s and early '70s, Skinner wrote several works applying his behavioral theories to society, including Beyond Freedom and Dignity He drew fire for seemingly implying that humans had no free will or individual consciousness. Noam Chomsky was among Skinner's critics. In , Skinner tried to set the record straight regarding any misinterpretations of his work with About Behaviorism. In his later years, Skinner took to chronicling his life and research in a series of autobiographies.

He also continued to be active in the field of behavioral psychology — a field he helped popularize. In , Skinner was diagnosed with leukemia. He succumbed to the disease the following year, dying at his home in Cambridge, Massachusetts, on August 18, Skinner's identification of the importance of reinforcement remains a critical discovery. He believed that positive reinforcement was a great tool for shaping behavior, an idea still valued in numerous settings including schools today. Skinner's beliefs are still being promoted by the B. Skinner Foundation, which is headed by his daughter, Julie S. We strive for accuracy and fairness. If you see something that doesn't look right, contact us!

Ralph Waldo Emerson was an American Transcendentalist poet, philosopher and essayist during the 19th century. One of his best-known essays is "Self-Reliance. Perhaps the most important of these was Burrhus Frederic Skinner. Although, for obvious reasons, he is more commonly known as B. Skinner's views were slightly less extreme than those of Watson Skinner believed that we do have such a thing as a mind, but that it is simply more productive to study observable behavior rather than internal mental events. The work of Skinner was rooted in a view that classical conditioning was far too simplistic to be a complete explanation of complex human behavior.

He believed that the best way to understand behavior is to look at the causes of an action and its consequences. He called this approach operant conditioning. According to this principle, behavior that is followed by pleasant consequences is likely to be repeated, and behavior followed by unpleasant consequences is less likely to be repeated. Skinner introduced a new term into the Law of Effect - Reinforcement.

A Skinner box, also known as an operant conditioning chamber, is a device used to objectively record an animal's behavior in a compressed time frame. An animal can be rewarded or punished for engaging in certain behaviors, such as lever pressing for rats or key pecking for pigeons. Reinforcers can be either positive or negative. Punishment weakens behavior. We can all think of examples of how our own behavior has been affected by reinforcers and punishers. As a child you probably tried out a number of behaviors and learned from their consequences. For example, if when you were younger you tried smoking at school, and the chief consequence was that you got in with the crowd you always wanted to hang out with, you would have been positively reinforced i.

If, however, the main consequence was that you were caught, caned, suspended from school and your parents became involved you would most certainly have been punished, and you would consequently be much less likely to smoke now. Positive reinforcement is a term described by B. Skinner in his theory of operant conditioning. In positive reinforcement, a response or behavior is strengthened by rewards, leading to the repetition of desired behavior.

The reward is a reinforcing stimulus. Skinner showed how positive reinforcement worked by placing a hungry rat in his Skinner box. The box contained a lever on the side, and as the rat moved about the box, it would accidentally knock the lever. Immediately it did so a food pellet would drop into a container next to the lever. The rats quickly learned to go straight to the lever after a few times of being put in the box. The consequence of receiving food if they pressed the lever ensured that they would repeat the action again and again. Positive reinforcement strengthens a behavior by providing a consequence an individual finds rewarding. Negative reinforcement is the termination of an unpleasant state following a response.

Negative reinforcement strengthens behavior because it stops or removes an unpleasant experience. Skinner showed how negative reinforcement worked by placing a rat in his Skinner box and then subjecting it to an unpleasant electric current which caused it some discomfort. As the rat moved about the box it would accidentally knock the lever. Immediately it did so the electric current would be switched off. The consequence of escaping the electric current ensured that they would repeat the action again and again. In fact Skinner even taught the rats to avoid the electric current by turning on a light just before the electric current came on.

The rats soon learned to press the lever when the light came on because they knew that this would stop the electric current being switched on. These two learned responses are known as Escape Learning and Avoidance Learning. Punishment is defined as the opposite of reinforcement since it is designed to weaken or eliminate a response rather than increase it. It is an aversive event that decreases the behavior that it follows. The behavior has been extinguished. Behaviorists discovered that different patterns or schedules of reinforcement had different effects on the speed of learning and extinction. Ferster and Skinner devised different ways of delivering reinforcement and found that this had effects on.

The Response Rate - The rate at which the rat pressed the lever i. The Extinction Rate - The rate at which lever pressing dies out i. Skinner found that the type of reinforcement which produces the slowest rate of extinction i. The type of reinforcement which has the quickest rate of extinction is continuous reinforcement. Behavior is reinforced only after the behavior occurs a specified number of times. For example, a child receives a star for every five words spelled correctly. One reinforcement is given after a fixed time interval providing at least one correct response has been made.

An example is being paid by the hour. Another example would be every 15 minutes half hour, hour, etc. For examples gambling or fishing. Providing one correct response has been made, reinforcement is given after an unpredictable amount of time has passed, e. An example is a self-employed person being paid at unpredictable times. The main principle comprises changing environmental events that are related to a person's behavior. For example, the reinforcement of desired behaviors and ignoring or punishing undesired ones. This is not as simple as it sounds — always reinforcing desired behavior, for example, is basically bribery. There are different types of positive reinforcements. Primary reinforcement is when a reward strengths a behavior by itself.

Secondary reinforcement is when something strengthens a behavior because it leads to a primary reinforcer. Token economy is a system in which targeted behaviors are reinforced with tokens secondary reinforcers and later exchanged for rewards primary reinforcers. Tokens can be in the form of fake money, buttons, poker chips, stickers, etc. While the rewards can range anywhere from snacks to privileges or activities. For example, teachers use token economy at primary school by giving young children stickers to reward good behavior.

Token economy has been found to be very effective in managing psychiatric patients. However, the patients can become over reliant on the tokens, making it difficult for them to adjust to society once they leave prison, hospital, etc. Staff implementing a token economy programme have a lot of power. It is important that staff do not favor or ignore certain individuals if the programme is to work. Therefore, staff need to be trained to give tokens fairly and consistently even when there are shift changes such as in prisons or in a psychiatric hospital. A further important contribution made by Skinner is the notion of behavior shaping through successive approximation.

Skinner argues that the principles of operant conditioning can be used to produce extremely complex behavior if rewards and punishments are delivered in such a way as to encourage move an organism closer and closer to the desired behavior each time. To do this, the conditions or contingencies required to receive the reward should shift each time the organism moves a step closer to the desired behavior.
