Skinner's+box

BF Skinner was one of the most influential researcher in behaviouristic approach. A new term in conditioning was introduced by him that is reinforcement. We can distinguish two types of reinforcement: positive and negative. He showed how positive reinforcement work on the example of a hungry rat. There was a lever in the box where the rat was put. Each time the rat accidentally pressed the lever, the food was released from the small hole. It did not take much time for a rat to learn that if it press the lever on purpose, it will get some food.
