Question

Quizplus · Accepted Answer

The Hawthorne effect occurs when participants alter their behavior in response to being observed or receiving special attention. This effect is most pronounced in the one-group repeated-measures design, as participants are repeatedly exposed to the same condition and may become more aware of being observed over time. The between-subjects and matched-subjects designs have less potential for the Hawthorne effect, as participants are only exposed to the experimental condition once and are not repeatedly observed. The assigned independent variable does not affect the potential for the Hawthorne effect.
