Which phenomenon describes the act of being studied causing a change in subjects?

• A. Placebo
• B. Hawthorne Effect
• C. Field Experiment
• D. Experimental Studies

Answer: (B)

The Hawthorne Effect describes changes in people’s behavior that occur simply because they know they are being observed or studied. This idea came from classic studies at the Hawthorne Works, where worker productivity increased not because of the specific changes in conditions like lighting, but because the workers realized they were part of a study and were receiving attention from researchers. In practice, any time participants or clients are aware they’re being watched or evaluated, they may alter their actions, report differently, or collaborate more, which can skew study results. This differs from a placebo, which relies on expectancy of receiving a treatment to produce improvement, rather than the mere fact of being observed. It also differs from field and experimental studies, which are types of research designs; the phenomenon in question is about how observation and attention influence behavior, not about the study design itself.
