Quizplus · Accepted Answer

Placebo or expectancy effects refer to changes in behavior that are not caused by the actual drug or treatment, but rather by the subject's beliefs and expectations. For example, if a person takes a sugar pill that they believe is a pain reliever, they may experience a reduction in pain even though the pill has no pharmacological ingredients.
