B.F Skinner demonstrated how positive reinforcement
works by placing a hungry rat in his Skinner box. The box contained a lever on
the side and as the rat started moving about the box, it would accidentally
knock the lever. Immediately as it happened a food pellet would drop into a
container next to the lever so the rat could feed of it .The rats immediately
learned to go straight to the lever after a few times of being put into the
box. “The consequence of receiving food if they pressed the lever ensured that
they would repeat the action repeatedly” (Learning
–theories, 2017).Positive reinforcement strengthens a behavior by
providing a consequence an individual finds rewarding. Removing unpleasant
reinforcement can also help to develop behavior.  This would be identified as negative
reinforcement because it has to get rid of an adverse stimulus, which is “rewarding” (learning theories,
2017) to the individual. Negative reinforcement
strengthens behavior because it stops or removes an unpleasant experience .B.F
Skinner “demonstrated how negative reinforcement worked on rats by placing a
rat in his Skinner box” (Simply psychology, 2017) and then putting it through to an unpleasant electric current,” which
caused it to irritate the rat”
( Learning-theories , 2017). As the rat started
moving in around the box, it would fortuitously knock the lever. Straight away as it did so, the
electric current would be turned off. The rats were aware that it should go
straight to the lever after being put in the box couple of time. The punishment
of getting away from the electric current ensured that they would repeat the
action repeatedly. In actuality, Skinner even trained the rats to keep away from
the electric current by switching on a light prior to electric current turning
on. In short, time the rats were taught to press the lever as soon the light
came on because they were conscious that this would stop the electric current
being switched on.
