Question

Quizplus · Accepted Answer

Lie detectors, or polygraphs, measure general emotional arousal rather than a specific "lie response," feelings like guilt and anger, or muscular responses. They typically monitor physiological indicators such as blood pressure, pulse, respiration, and skin conductivity, which can increase during emotional arousal, including when someone is lying. However, these responses are not unique to lying, hence the controversy over their reliability.
