Answer:
B) B. F. Skinner
Explanation:
In 1948, B. F. Skinner, a behavioral psychologist, published his novel <em>Walden Two. </em>In his novel, Skinner describes a Utopian community, called "Walden Two," that is entirely ruled by operant conditioning - <em>a learning method in which punishments and rewards are used. </em>
This society is around one-thousand people and is governed by behavioral principles. They all seem to be quite happy with their lifestyles. Here, people tend to work for an average of four hours a day and are not paid with money, as it does not have a value in Walden Two. Everything here is experimental and people are "trained" or "conditioned" since childhood to reach efficiency and improvement.
