Quizplus · Accepted Answer

Demand characteristics refer to participants' tendency to change their behavior or responses in a study because they believe they are supposed to act a certain way. This can occur when participants try to please the researcher, or when they actively try to sabotage the study by behaving in a way that they think will discredit the research. Demand characteristics can affect the validity of study results by introducing bias into the data.
