Hawthorne Study and Worker Productivity

The question asks about the individual responsible for conducting the Hawthorne study, specifically the part that examined the relationship between the intensity of illumination and workers' productivity. This renowned series of experiments in industrial psychology was primarily led by a prominent figure in the field.

Elton Mayo's Pivotal Role in Hawthorne Studies

The Hawthorne studies were a groundbreaking series of experiments conducted at the Western Electric Company's Hawthorne Works in Cicero, Illinois, starting in 1924 and continuing through the early 1930s. The primary research leader for these studies was Elton Mayo.

Initially, the research began with investigations into physical working conditions, such as lighting (illumination), and their effects on worker productivity. However, the unexpected results of these initial experiments led the researchers to delve deeper into other factors affecting productivity, particularly social and psychological aspects.

Illumination Experiment Details

The very first phase of the Hawthorne studies, often referred to as the Illumination Experiment (1924-1927), aimed to determine if changes in lighting levels would directly impact employee output. Researchers systematically altered the intensity of illumination in various work areas. The surprising discovery was that productivity tended to increase regardless of whether the light was brightened or dimmed, and even in control groups where lighting remained constant.

This led to the realization that factors other than physical conditions were at play. The workers' awareness of being observed, the attention they received from researchers, and the improved social dynamics within the experimental groups had a more significant impact on their productivity than the physical changes in illumination. This phenomenon later became known as the Hawthorne Effect.

Impact of Hawthorne Studies and Other Researchers

The Hawthorne studies, under Elton Mayo's direction, shifted the focus of management theory from a purely mechanical view of workers to one that recognized the importance of human and social factors in the workplace. These studies laid the foundation for the Human Relations Movement in management.

While Elton Mayo was the primary leader, other researchers were also involved in various phases of the Hawthorne studies, including Fritz Roethlisberger and William J. Dickson. However, for the overall direction and the interpretation of the human relations aspect, Elton Mayo is most closely associated with the studies.

• Elton Mayo: Key figure in the Human Relations Movement and the leader of the Hawthorne studies.
• Abraham Maslow: Known for his hierarchy of needs theory, not directly involved in the Hawthorne studies.
• Kurt Lewin: Famous for his work on group dynamics and field theory, separate from the Hawthorne studies.
• Mary Parker Follett: An early management theorist who emphasized integrated social relationships, but not the conductor of the Hawthorne studies.

Therefore, the Hawthorne study, particularly the investigation into illumination and productivity, was conducted by Elton Mayo and his team.
