In B.F. Skinner's theory, positive reinforcement is defined as a
             presented stimuli that works to increase or strengthen the probability of a
             response. An example of this would be a food treat for a dog in return for
             sitting behavior. A negative reinforcement is defined as the removal of
             stimuli that acts to increase or strengthen a response. An example of this
             would be yelling at a child to stop crying, and having the crying behavior
             stop. While the action of yelling was negative, the response was positive,
             in that the child stopped crying, thus increasing the likelihood that a
             person will yell to get the child to stop crying. Punishment is defined as
             an action to temporarily repress behavior, such as the removal of
             television privileges for a child who fails a class. This "punishment"
             would temporarily serve as a repression to the behavior of receiving bad
             Walden II, B.F. Skinner's world of utopia, is a model illustration of
             what needs to be done in order for humans to be happy, rather than just
             furthering the happiness of the ruling class or the majority. The idea
             that humans are born with nothing, that we are then the product of our
             history, and thus, that we learn all the problems we have, is a wonderful
             idea. If this were true, then Walden II would work: no one born in the
             world would learn the behaviors, and everyone who had previously learned
             them could simply unlearn them. Without social pressures, and with all
             needs met, there would be no need for corruption. In the modern world,
             however, this idea is just that: an idea. Even if all the technologies
             were in place, we now know, through modern medicine and psychiatry that
             some behaviors are inane, and thus very difficult to unlearn. While life
             in Walden II would be blissful, it would also be impossible.
