In recent years, during the investigation and interrogation of some criminal cases, the public security organs and procuratorial organs have not only used the traditional means of investigation and interrogation but also employed some psychological test equipment and technology in order to solve difficult cases. Psychological tracking technology which is an important extension of psychological test technology has also being developed and valued gradually. Psychological tracking technology applied to the investigation and interrogation is able to discover more important information which suspects want to hide. In addition, the information may be the key to uncover the whole case or to look for hidden clues. Therefore, it is necessary to research the role which psychological tracking technology play in the course of investigation and interrogation.Psychological tracking technology is a new technical mean of investigation and interrogation. It means investigators collect the information about abnormal physiological responses of criminal suspects with the help of psychological tracker and verbal stimulation and thus the psychological trace can be tracked. Psychological tracking technique applied to the criminal investigation activities enable to increase the channels to collect case information for investigators, understand the personal characteristics of criminal suspects and provide specific guidance for further development of spying.At present, the employment of psychological tracking technique in the procuratorial organ and public security organ is still at an early stage. However, it has obtained ideal effect in economic crime investigation and duty crime investigation. The technique has several advantages, such as, simple operation, less restrictive for the testers, the synchronization of investigation and interrogation. In consequence, it can add technical support to traditional interrogation, improve the quality of interrogation, provide clues to criminal cases and narrow the scope of investigation.The use of psychological tracker can not only monitor the physiological and psychological change of the criminal suspects timely, but also master their psychological fluctuations to improve the efficiency of investigation through the monitoring of the instrument. In the meanwhile, the psychological tracker equipped with the function of sound recording and video recording is better to prevent some illegal means to obtain evidence. Although test results cannot be used as evidence directly, it plays a supporting role in the course of investigation and interrogation. Therefore, study of the technique in the matter of science, operation and widespread use possesses forwarding looking and urgency.In this thesis, the psychological tracking technology will be discussed and studied from several aspects, such as, the basis, experimental results, application and several remaining issues so that it can play a significant role in the interrogation and investigation of criminal cases on the one hand and provide more breakthrough point for investigation and interrogation to raise the science of the interrogation. The study of psychological tracking technology also accord with the urgent requirements of scientific interrogation and legal interrogation, which has great practical significance.
