Pioneering work began in the 1920s as an attempt to discover ways to increase production efficiency.  Elton Mayo, a Harvard researcher, looked at the results of early motivation experiments and concluded that psychological and social factors played a larger role in productivity than physical elements.

In 1927, researchers were trying to determine the optimal amount of lighting, temperature, and humidity for assembling electronic components at Western Electric's Hawthorne plant.  The results showed that lighting had no consistent effect on production.  Researchers were frustrated to discover that increasing light increased output, but reducing light also increased output.  The common factor, it seemed, was that something in the work environment was changed, and that positive effects were then observed.

After thoroughly examining the results, Elton Mayo and his fellow researchers determined that workers weren't responding to the change in lighting conditions, but instead were reacting to the fact that they were being observed by the experimenters.  This phenomenon became known as the Hawthorne effect.  The workers' awareness that researchers were measuring their productivity was sufficient to increase productivity.
