Burrhus Frederic Skinner (1904-1990) was an American psychologist and behaviorist. He believed that all human actions depend on the results of previous actions. If these results are good, they are likely to be repeated and strengthened, a notion he called the principle of reinforcement. He invented the ‘operant conditioning chamber’, also called the Skinner Box, for his experiments on strengthening behavior by reward or punishment, using animals or birds such as pigeons. He published 21 books and 180 articles and is often considered to be the most influential psychologist of the 20th century. Controversial to the end, B.F. Skinner was renowned for his unconventional methods, including the famous ‘Little Albert’ experiment.
