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 ...
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]
The original Sally–Anne cartoon used in the test by Baron-Cohen, Leslie and Frith (1985) The Sally–Anne test is a psychological test originally conceived by Daniel Dennett, used in developmental psychology to measure a person's social cognitive ability to attribute false beliefs to others. [1]
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]
Another shortcoming lies in the definition of reliability that exists in classical test theory, which states that reliability is "the correlation between test scores on parallel forms of a test". [5] The problem with this is that there are differing opinions of what parallel tests are.
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
The use of voice stress analysis (VSA) for the detection of deception is controversial. Discussions about the application of VSA have focused on whether this technology can indeed reliably detect stress, and, if so, whether deception can be inferred from this stress. [2]
