The role of comparison questions in physiological detection of deception.
Comparison questions in physiological detection of deception were studied with 60 "guilty" and 60 "innocent" participants in a mock crime experiment and produced different patterns of physiological responses for innocent but not for guilty participants.
Mental and physical countermeasures reduce the accuracy of polygraph tests.
Effects of countermeasures on the control-question polygraph test were examined in an experiment with 120 Ss recruited from the general community and found that the countermeasures were difficult to detect either instrumentally or through observation.
