The main task of software of detecting a lie is by to psychology physiology signal acquisition system 1 and the Physiological Psychology data that obtain of window signal process software 2 for a long time, adds up, analyzes, comprehensively draws the conclusion of detecting a lie.
Specific to drawing of the conclusion of detecting a lie, mainly be by being analyzed as follows relevant physiological psychology data:
1) the physiological parameter of cognitive components such as P300 as the extra power consumption of unusual execution function in lying.
Human to look, the information processing of listening is that the sensation cortex of looking, listen from back or side head carries out step by step to the advanced contact cortex of top and fore head, elementary unconscious automatic processing is not subjected to the influence of whether lying; But the processing merit activity of senior consciousness is very responsive to the core link of lying.Such as, utilize to be familiar with and the strange face photo is simulated and detected a lie, the detection photo of being familiar with is deliberately made the reaction of strange photo, the target stimulation photo of being familiar with carried out normal reaction.The result surveys to stimulate the P300 wave amplitude that brings out always to be lower than target stimulation, because the core link of lying has expended psychological physiology energy.In recent years based on the circumstances of crime test (GKT) of P300 ripple, stimulate the nothing to do with stimulation to compare, can induce the P300 ripple of remarkable high amplitude, regard the evidence of remembering the plot of committing a crime in tested person's brains as surveying.The present invention both the change of cognitive components such as P300 and N400 ripple as physiological parameter to circumstances of crime memory, more physiological parameter that it is additionally consumed energy as the unusual implementation of working memory executor institute.So the P300 wave amplitude that the detection photo is drawn significantly is lower than target stimulation.
2) the MFN ripple is accompanied by the physical signs of superpower control function as lying
The present age, cognitive neuroscience showed, when the complex task, the central executor of working memory not only bears and carries out function also to implementation proper monitoring the whether.The brain structure relevant with this function mainly is inboard prefrontal lobe and anterior cingutate, and medial prefrontal negative wave (MFN) is its activated physical signs.The present invention is accompanied by high-amplitude MFN ripple the physical signs of superpower control function as lying.
3) in conjunction with brain frontal region physiological parameter and periphery physical signs, emotion is carried out analysis-by-synthesis
Lying not only comprises cognition to relevant issues, i.e. consciousness, memory and attention, and also inevitable emotion locomotor activity with complexity comprise nervous anxiety, ambivalence, motivation conflict etc.The present age, the emotion cognition neuroscience proved, except slow physiological reaction by the periphery autonomic nervous function (breathing, heart rate and skin) of forehead island leaf regulation and control, emotional activity also causes the fast reaction of brain by corpus amygdaloideum and thalamus, will physiological change occur in prefrontal lobe at about 0.1 second that accepts to stimulate.Therefore, detect the relevant physiological parameter of the different emotion of two class sequential, analyze the emotional response of being followed in the process of lying by prefrontal lobe electrode and nasopharyngeal electrode.With brain particularly the physiological parameter and the periphery physical signs of frontal region carry out analysis-by-synthesis, in the present invention as detecting a lie the important step of technology.
4) the lie sequential of mental activity in the process and related physiological parameters thereof
Lying is a kind of mental activity of complexity, contain the different cognition of multiple sequential, emotion and decision-executing process, fast reaction betides to stimulate and presents back 0.05 second and the P50 ripple occurs, in tested reaction the MFN ripple takes place to occur in back 0.07 second, these reflect window when now fast, are referred to as window reaction when fast; The variation of breathing and pulse appears in 1s～4s, window reaction in the time of in being called; The slow physiological reaction of the skin electricity that occurs in 5～15 seconds behind tested button or responsing reaction is called window reaction when slow.The present invention is by to the reaction of window for a long time, and the window reaction is carried out rounded analysis, a kind of completely new approach that provides for accurately detecting a lie when window reaction and 5s during window reaction during promptly negative 0.2s～1s, 1s～4s～20s.
5) physiological parameter of stimulation time locking and response time locking
In the process of detecting a lie, fierce mental activity can take place after reacting in the moment of accepting to stimulate with to stimulation in the tested person, therefore except three time-like windows, and synergetic time point when also having two locks.
Analysis, application with above-mentioned Physiological Psychology parameter at last forms the new normal form of detecting a lie, promptly new lie detecting method.
So far, the existing normal form of detecting a lie is based on the circumstances of crime test (GKT), criterion problem test (CQT) of polygraph etc.; The GKT method also is used in Oddball based on the event related potential normal form of detecting a lie.The present invention absorbs following method from the basic research of Modern Cognitive neuroscience, as the normal form of newly detecting a lie:
1) Go/No-Go Paradigm requires testedly to target stimulation button (Go), and non-target stimulation is not done reaction (No-Go), how to surveying irritant reaction by tested own definite.Compare three classes P300 composition that stimulates and the difference of reacting preceding positive wave (PRP).Because it is approaching to survey stimulation and target stimulation character, honest person should make the GO reaction, and the liar suppresses this reaction, provides the NOG0 reaction; But the similar GO effect of its ERP.Adopt the stacked system of stimulation time locking to handle ERP.This is to the unusual detection of carrying out function of liar.
