Tag: Hawthorne effect

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. The effect was discovered in the context of research conducted at the Hawthorne Western Electric plant; however, some scholars think the descriptions are fictitious.

The original research involved workers who made electrical relays at the Hawthorne Works, a Western Electric plant in Cicero, Illinois. Between 1924 and 1927, the lighting study was conducted, wherein workers experienced a series of lighting changes that were said to increase productivity. This conclusion turned out to be false. In an Elton Mayo study that ran from 1927 to 1928, a series of changes in work structure were implemented (e.g. changes in rest periods) in a group of six women. However, this was a methodologically poor, uncontrolled study from which no firm conclusions could be drawn. Elton Mayo later conducted two additional experiments to study the phenomenon: the mass interviewing experiment (1928-1930) and the bank wiring observation experiment (1931-32).

One of the later interpretations by Henry Landsberger, a sociology professor at UNC-Chapel Hill, suggested that the novelty of being research subjects and the increased attention from such could lead to temporary increases in workers' productivity. This interpretation was dubbed "the Hawthorne effect".
