As "Prospects of fMRI as a Lie Detector" [9] states, fMRIs use electromagnets to create pulse sequences in the cells of the brain. The fMRI scanner then detects the different pulses and fields that are used to distinguish tissue structures and the distinction between layers of the brain, matter type, and the ability to see growths.
Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. [ 1 ]
American inventor Leonarde Keeler testing his improved polygraph on Arthur Koehler, a former witness for the prosecution at the 1935 trial of Richard Hauptmann. A polygraph, often incorrectly referred to as a lie detector test, [1] [2] [3] is a pseudoscientific [4] [5] [6] device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration ...
The Silent Talker Lie Detector is an attempt to increase the accuracy of the most common lie detector, the polygraph, which does not directly measure whether the subject is truthful, but records physiological measures that are associated with emotional responses.
Brain fingerprinting (BF) is a lie detection technique which uses brain waves from a electroencephalography (EEG) to determine whether specific information is stored in the subject's cognitive memory. It was invented by Larry Farwell, a Harvard-graduated neuroscientist, and published in 1995. [1]
William Moulton Marston (May 9, 1893 – May 2, 1947), also known by the pen name Charles Moulton (/ ˈ m oʊ l t ən /), was an American psychologist who, with his wife Elizabeth Holloway, invented an early prototype of the polygraph.
Lie detector is the popular term for a polygraph, a device that measures and records physiological indices, under the belief that these are useful for lie detection. Lie Detector may also refer to: Silent Talker Lie Detector , an alternative to the polygraph, invented between 2000 and 2002
Lie detectors use questioning techniques in conjunction with technology to measure human responses to these stimuli to attempt to ascertain if that person is lying or telling the truth. The most longstanding and still most frequently used measure is the polygraph test.
