He returned to Harvard in as a professor, and was the Edgar Pierce Professor of Psychology from until he retired in Skinner was influenced by John B. In a utopian novel called Walden Two and a bestseller called Beyond Freedom and Dignity, he argued that human behavior was always controlled by its environment. According to Skinner, the future of humanity depended on abandoning the concepts of individual freedom and dignity and engineering the human environment so that behavior was controlled systematically and to desirable ends rather than haphazardly.
In the laboratory, Skinner refined the concept of operant conditioning and the Law of Effect. We strive for accuracy and fairness. If you see something that doesn't look right, contact us!

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. According to Skinner, most animal and human behavior including language can be explained as a product of this type of successive approximation.
In the conventional learning situation, operant conditioning applies largely to issues of class and student management, rather than to learning content. It is very relevant to shaping skill performance. A simple way to shape behavior is to provide feedback on learner performance, e. A variable-ratio produces the highest response rate for students learning a new task, whereby initially reinforcement e.
For example, if a teacher wanted to encourage students to answer questions in class they should praise them for every attempt regardless of whether their answer is correct. Gradually the teacher will only praise the students when their answer is correct, and over time only exceptional answers will be praised.
Unwanted behaviors, such as tardiness and dominating class discussion can be extinguished through being ignored by the teacher rather than being reinforced by having attention drawn to them. Knowledge of success is also important as it motivates future learning.
However, it is important to vary the type of reinforcement given so that the behavior is maintained. Skinner's study of behavior in rats was conducted under carefully controlled laboratory conditions. Note that Skinner did not say that the rats learned to press a lever because they wanted food.
He instead concentrated on describing the easily observed behavior that the rats acquired. In the Skinner study, because food followed a particular behavior the rats learned to repeat that behavior, e. Therefore research e. Skinner proposed that the way humans learn behavior is much the same as the way the rats learned to press a lever.
