I think it's subject bias effect.

anonymous · Answer

thank you so much! Are you sure?

snowxangel · Answer

Well it also might be placebo effect..... Because subject bias effect is when the participant believes they know the purpose of the study and performs in a way that will support or discredit your experiment. And placebo is when is the measurable, observable, or felt improvement in health or behavior not attributable to a medication or invasive treatment that has been administered.
