Chances are you would not give up right away, you would try several times by jiggling they key into the lock in different ways. If this doesn"t work then you would eventually quit trying. This was illustrated by a study by neuringer: Rats were separated into two groups in the experiment. The apparatus and procedure were set up to facilitate the measurement of response variability. levers on one wall and a round response key on the opposite. During the reinforcement phase, the rats had to make three responses in a row to obtain wall. the food pellet.
