One interpretation, mainly due to Elton Mayo, was that 'the six individuals became a team and the team gave itself wholeheartedly and spontaneously to cooperation in the experiment.' (There was a second relay assembly test room study whose results were not as significant as the first experiment.) Researchers hypothesized that choosing one's own coworkers, working as a group, being treated as special (as evidenced by working in a separate room), and having a sympathetic supervisor were the real reasons for the productivity increase. Researchers concluded that the workers worked harder because they thought that they were being monitored individually. However, it is said that this is the natural process of the human being adapting to the environment, without knowing the objective of the experiment occurring.

Shortening the day by 30 minutes (output went up) shortening it more (output per hour went up, but overall output decreased) returning to the first condition (where output peaked).Ĭhanging a variable usually increased productivity, even if the variable was just a change back to the original condition.

Productivity increased, but when they received six 5-minute rests, they disliked it and reduced output.

Giving two 5-minute breaks (after a discussion with them on the best length of time), and then changing to two 10-minute breaks (not their preference).

In the experiment room they had a supervisor who discussed changes with their productivity.

This measuring began in secret two weeks before moving the women to an experiment room and continued throughout the study. Output was measured mechanically by counting how many finished relays each worker dropped down a chute. Together the women worked in a separate room over the course of five years (1927–1932) assembling telephone relays. In one of the studies, researchers chose two women as test subjects and asked them to choose four other workers to join the test group. Thus the term is used to identify any type of short-lived increase in productivity. Īlthough illumination research of workplace lighting formed the basis of the Hawthorne effect, other changes such as maintaining clean work stations, clearing floors of obstacles, and even relocating workstations resulted in increased productivity for short periods. Only occasionally are the rest of the studies mentioned. Most industrial or occupational psychology and organizational behavior textbooks refer to the illumination studies when discussing the Hawthorne effect. In these lighting studies, light intensity was altered to examine its effect on worker productivity. This effect was observed for minute increases in illumination. It was suggested that the productivity gain occurred as a result of the motivational effect on the workers of the interest being shown in them. The workers' productivity seemed to improve when changes were made, and slumped when the study ended. The Hawthorne Works had commissioned a study to determine if its workers would become more productive in higher or lower levels of light. Landsberger when he was analyzing the Hawthorne studies conducted between 19 at the Hawthorne Works (a Western Electric factory in Cicero, outside Chicago). The term 'Hawthorne effect' was coined in 1958 by Henry A. This interpretation was dubbed 'the Hawthorne effect'.Īerial view of the Hawthorne Works, ca. One of the later interpretations by Landsberger suggested that the novelty of being research subjects and the increased attention from such could lead to temporary increases in workers' productivity. However, this was a methodologically poor, uncontrolled study that did not permit any firm conclusions to be drawn.

In the study that was associated with Elton Mayo, which ran from 1928 to 1932, a series of changes in work structure were implemented (e.g., changes in rest periods) in a group of five women. Workers experienced a series of lighting changes in which productivity was said to increase with almost any change in the lighting. Between 19, the lighting study was conducted. The original research involved workers who made electrical relays at the Hawthorne Works, a Western Electric plant in Cicero, Illinois. The effect was discovered in the context of research conducted at the Hawthorne Western Electric plant however, some scholars feel the descriptions are fictitious. The Hawthorne effect is a type of human behavior reactivity in which individuals modify an aspect of their behavior in response to their awareness of being observed. Social phenomenon where watching causes changes
