Once the data has been collected it is analysed in 行う／開催する／段階 three and the results are 発表するd. Examiners say 神経s should not 影響する／感情 the results.

Deceptive answers produce physiological 返答s that are different to truthful answers.

The machine was invented in 1921 by John Augustus Larson at the University of California at Berkeley と一緒に a police officer.

In another 事例／患者, a paedophile 自白するd he had started dating a woman, 主要な 捜査官／調査官s to discover he had been undressing in 前線 of her young daughter.

Psychiatrist Don Grubin, who helped run the Midlands 裁判，公判, said: ‘I have no 疑問 that serious offences have been 妨げるd through use of this 科学（工学）技術.’

The 政府 hopes to have the £4,000 polygraph machines - which 監視する a person's heart 率, breathing and 血 圧力 - up and running by 2014.

'The 最近の 操縦するs into using 嘘（をつく） detector 実験（する）s to manage sex 違反者／犯罪者s in the community has 証明するd a （疑いを）晴らす success and we are now considering how we will use them across England and むちの跡s 支配する to 議会の 是認.

'This will be good news for the public who should 利益 from this extra 層 of 保護.'

The 操縦する 計画／陰謀 in the Midlands, run by the 省 of 司法（官）, 設立する that the 嘘（をつく） detector 実験（する）s led to 違反者／犯罪者s 存在 more honest with their 保護監察 officers.

They made twice as many 公表，暴露s to staff as those who were quizzed without the polygraphs.

The compulsory use of 嘘（をつく） detectors was challenged under human 権利s 法律制定 but 裁判官s 支援するd the? use of polygraphs, 説 that they were ‘proportionate’.

法律制定 to 実験（する） polygraphs on sex 違反者／犯罪者s was introduced by 労働. The 連合 is now planning 第２位 法律制定 to use it? on the most serious sex 違反者／犯罪者s in England and むちの跡s.
