Caption: Experiment by Skinner. Burrhus Frederic Skinner (1904-1990, left), was an American experimental psychologist who carried out most of his work at Harvard University, USA. He used pigeons to study stimulus-response behaviour, using structures that were called Skinner boxes. The pigeons had to peck lit-up discs to obtain food. Pigeons were used, as they can perform a wider range of tasks and have a longer lifespan than rats. Skinner developed a theory of operant conditioning that states that a stimulus can act to reinforce behaviour. Skinner's work influenced educational theories. He is also known for his book Walden Two (1948), on a utopian society run on his operant principles.
