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

rats firstly press the lever by mistake, but that begins to happen more and
more. After some time, rats learn that when they press the lever they get food
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.
