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]
Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates.
The procedure begins by attaching sensors called electrodes to the subject's scalp to form a circuit that quantifies brain activity using a test called an electroencephalogram (EEG). [5] When conducting an EEG to measure electrical activity in the brain, a distinctive surge of electrical activity may appear between 300 and 800 milliseconds ...
A half-truth is a deceptive statement that includes some element of truth.The statement might be partly true, the statement may be totally true, but only part of the whole truth, or it may use some deceptive element, such as improper punctuation, or double meaning, especially if the intent is to deceive, evade, blame or misrepresent the truth.
These early studies found initially that "although humans are far from infallible in their efforts to diagnose lies, they are substantially better at the task than would result merely by chance." [ 12 ] Additionally, research has shown that deception and suspected deception occurs in at least one quarter of all conversations.
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 ...
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.
