John B. Skinner, known as B.F. Skinner, was born in Pennsylvania in March 20, 1904. His father was a lawyer and his mother stayed home. As a boy, he enjoyed building gadgets. He attended Hamilton College to pursue his passion in writing; however, he had no success. He later attended Harvard University to pursue another passion, human psychology. He studied operant conditioning using a box, also known as Skinner box. He studied the behavior of rats and pigeons and how they respond to their environment. He was the chair of psychology in Indiana College, but he later became a Harvard professor. He later published the book The Behavior of Organisms based

He took an environmental approach to the study. His method was the use of the operant conditioning box also known as Skinner box helped understand different behaviors that occurred during different environments. He stimulated a system of rewards and punishments and reinforcements. When the pigeon or rat received a reward, the animal performed the behavior more often and when it received a punishment, it performed the behavior less. He first tested positive reinforcement which he made rats press a lever for food. It encouraged the rat to perform more of the behavior. He also used negative reinforcement which added an uncomfortable stimulus. He placed an electric current in the box. The rats learn to avoid it. They even learned to stop when he turned on the light indicating the circuit will soon turn on. This behavior was known as Avoidance or Escape Learning. Both positive and negative reinforcements encourage good behavior. He also used punishment. Unlike the reinforcements, punishments were used to discourage unwanted behaviors rather than promote good behavior. It was performed by adding an unfavorable stimuli or removing the rewarding stimuli. When the rat was punished, its unwanted behavior decreased. When Skinner, removed the punishment, the bad behavior returned. He placed a hungry rat. The rat would pull the lever for food, but no food would come out. The rat later stopped pulling it learning it had no purpose. He studied that the more the rat pulled the lever, the higher the probability that the rat will quit pulling it; he developed an equation known as response and extinction rate. Response rate, the domain, is that rate of how hard a person performed an action and extinction rate, the range, is the rate that the person performed the action less and less. As the response rate increase, so this extinction rate. He used a token economy, a type of positive reinforcement, which a person was given a “token” which can be
