Operant chamber is
laboratory apparatus consisted of the response lever, electrified grid and food dispenser.
Operant chamber (also known as Skinner’s box) is a
typical laboratory chamber (apparatus) in which the behavior and learning
process of rats was examined. This chamber is mostly empty, it has a food
dispenser, response lever which gives food when it’s pressed and sometimes
electrical greed. With this chamber, Skinner has learned in his research that
rats firstly press the lever by mistake, but that begins to happen more and

as a reward. At the other experiment, rat have learned the same way that when
they press the lever, the electrified grid is turned off.
