Question

Quizplus · Accepted Answer

A demand characteristic refers to when a participant responds in a way that they believe the experimenter wants them to behave, rather than their true behaviour. This can lead to results that are biased or not representative of the participant's genuine response. For example, if a participant believes that the experimenter is testing a new drug and expects positive results, they may be more likely to report feeling better, even if they do not actually feel any different.
