Reading Passage Question

A famous series of studies, known as the Hawthorne Studies, was the first to explore psychological factors that affect work performance. These studies attempted to investigate the relationship between the level of lighting in the workplace and worker productivity. Researchers divided workers into two similar groups – a test group, who were subjected to changes in lighting, and a control group, whose lighting remained constant. No other changes were made. When the test group's lighting was improved, the group’s productivity increased. But when lighting conditions were made worse, there was also a tendency for productivity to increase in the test group. To compound the mystery, the control group's output also rose, even though the group experienced no changes in lighting. Something besides lighting was influencing the workers' performance. In a new set of experiments, a new test group was placed in a separate room and a number of variables – wages, rest periods, and the length of the workday – were altered in all directions. Again, performance tended to increase over time. The researchers decided that a complex chain of attitudes had caused the productivity increases. Because they had been singled out for the experiments, workers in the test group had developed a group pride that motivated them to improve their work performance. Sympathetic supervision had further reinforced their motivation. The researchers concluded that individuals in a group perform better if they believed that their group was paid special attention. This phenomenon was subsequently labeled the Hawthorne Effect.
