The one, cognitive psychological.A people does something, the particularly planning of the premediation before offender's crime, the environment during crime, plot, the misery expression of killed object, weapons of offence and criminal consequence etc. all can because trained reflex produces strong Psychological stimulation, cause the ANOMALOUS VARIATIONS of physiological parameter.
The 2nd, the psychology of lying.Lying is to provide statement a kind of falseness, that be not inconsistent the fact to the people consciously, and camouflage allows the other side not know that he is telling a lie as far as possible.In crime survey, the suspect covers an important self-protection arms of own criminal behavior and lies exactly.He will lie, and be afraid of that again lie is disclosed, thereby cover up by fair means or foul, so that the abnormal mind state weave in such as very complicated, nervous, frightened, flurried, form heavy mental pressure, thereby cause physiological abnormal response.
Present psychological tester function is comparatively single, and the physiological data that can detect is less, and data transmission efficiency is lower.For example CN 201200410Y discloses a kind of a lie detector with skin temperature detector brake, it comprises housing, be provided with the skin temperature detector slowdown monitoring circuit for detection of skin temperature physiological parameter in the described housing, this skin temperature detector slowdown monitoring circuit comprises temperature sensor, signal amplifier and analog-digital converter, this temperature sensor is worn on the position to be detected of tested person's health, this temperature sensor links to each other with analog-digital converter by signal amplifier, and this analog-digital converter links to each other with microcontroller.The human body physiological parameter of this a lie detector monitoring is more single, affects final accuracy of measurement.
