The Hawthorne effect: A reconsideration of the methodological artifact.

Reviews the literature on the Hawthorne effect (HE) which originated out of the studies at the Hawthorne Works of the Western Electric Company. This effect is generally defined as the problem in field experiments that Ss' knowledge that they are in an experiment modifies their behavior from what it would have been without the knowledge. An examination of the Hawthorne studies conducted 50 yrs ago does not reveal this “effect” probably because there were so many uncontrolled variables. HE is inconsistently described in contemporary psychology textbooks, and there is lack of agreement on how the effect is mediated. Controls for the HE in current field research (mostly in education) took several forms, each designed for different purposes. In 13 studies designed to produce HEs, only 4 using adult Ss were successful. It is suggested that most persons in any clearly identified situation define the context for their behavior and respond accordingly; the necessity to ascertain Ss' view of the experiment requires different procedures than those typically used to control for HEs in the past. It is concluded that better articulation of how to adapt postexperimental questioning procedures to a diversity of experimental settings is needed.
