Study technology test new generation lie

Loudness testing technology has been widely used in many fields, but people are always skeptical about the accuracy of this technology.

Scientists at the University of Oxford in the United Kingdom have been studying new generation lie test technology that could improve accuracy when conducting tests.

New generation lie detection technology mainly performs judgment on whether the tested person believes in information from the outside world by checking the accuracy of the brain waves.

The scientists conducted the experiment by asking some participants to "choose the box ." Before selecting the box, the participants were suggested some issues related to the selection.

First, the participants make judgments about the reliability of the suggestions, then make their own choices. In this process, scientists will examine the brain activity of the participants.

The results showed that when subjects were skeptical about the implications, the preoperative index of the dorsomedial nucleus in the cerebrum suddenly increased. While the subjects trust the suggestions, the index is lower. Through this, scientists can examine the level of credibility of the participants for previous suggestions.

This technology is not only applicable to lie test devices, but can also help explain why some people have paranoid.
