ABSTRACT Polygraph, as a traditional lie detector, is used to detect lies by some changes of human peripheral neuro-vegetative responses. The reliability of this technique, which depends on some other none-instrumental factors to a great extent, has drawn lots of attention and question. Event related potentials (ERPs) have good specificity and time resolution and can monitor instant cognitive processing and brain electric activity. However, its space resolution is poorer than brain function nuclear magnetic resonance imaging (fMRI) relatively. Brain fMRI can show the brain functional changes directly. It has good space resolution but bad time resolution, and all images of fMRI are just the final results of brain changes after lying. So, fMRI technique for detecting deception is still in the basic research phase at present. Contrary to other techniques, psychometrics has been used and studied more in detecting deception or malingery in practice.

    ABSTRACT: Although China has a long history of forensic psychiatry, which can be traced even back to Zhou dynasty (11th century B.C.). However, modern forensic psychiatry has not been set up in China until the 1970s. After the interruption of Cultural Revolution of 1966-1976, there was a period of rapid development. In the past five years, a series of judicial identification system reforms have been taking place. In 2010, China had 225 forensic psychiatry agencies, 2,090 forensic psychiatry experts and 40,822 cases. The experts are organized within the separate agencies of Psychiatric hospital, universities, the Institute of Forensic Sciences of the Ministry of Justice and other forensic agency. Apart from criminal forensic psychiatry, the experts are often asked to evaluate civil competency for the clients involved in civil litigation. Chinese forensic psychiatry has developed rapidly during the past 30 years, and formed the characteristics of its own under the special legal system. However, there is still much work for Chinese forensic psychiatrist to do for the future.
