While Researchers Changed the Work Environment to See How It

question 45

Multiple Choice

While researchers changed the work environment to see how it affected worker productivity, they got surprising results. No matter what conditions the researchers changed (such as increasing the lighting) , the workers seemed to work harder simply because they were part of a special experiment.

• A) The Hawthorne Effect
• B) The double-blind experiment
• C) Compensatory rivalry
• D) Selection bias
• E) The Solomon Four Group design
