Quizplus · Accepted Answer

A confederate is a person who appears to be a participant in an experiment but is actually working with the researchers to manipulate the situation. They are also sometimes referred to as "stooges" or "plants". Mediators and arbitrators are not typically involved in experimental manipulations, and a nonconcealed observer would not be pretending to be a participant.
