Placebo, Hawthorne, and Other Artifact Controls: Researchers' Opinions and Practices.

Adair, John G.; And Others

Journal of Experimental Education, v57 n4 p341-55 Sum 1989

Although some consistency in practice was found, surveys revealed confusion among researchers over the definition of and relationship between both sources of artifact and placebo, Hawthorne, and attention-placebo controls.
