A psychophysiological technique used to determine whether a person has information related to a particular event, usually as part of criminal investigations. During the test, the examinee is presented with multiple-choice questions, including one correct (related to the crime) and several neutral ones. Physiological responses – such as galvanic skin response, heart rate, or respiration – are measured for each variant. A more pronounced reaction to the correct answer indicates recognition and, therefore, the presence of hidden knowledge about the event. The GKT/CIT is considered to be less prone to false positives than the traditional polygraph because it focuses on recognizing information rather than detecting deception.
