illustrate the function of a polygraph machine
1. illustrate the function of a polygraph machine
Answer:
lie detector, also called polygraph, instrument for recording physiological phenomena such as blood pressure, pulse rate, and respiration of a human subject as he answers questions put to him by an operator; these data are then used as the basis for making a judgment as to whether or not the subject is lying. Used in police interrogation and investigation since 1924, the lie detector is still controversial among psychologists and not always judicially acceptable.

2. Is a polygraph machine a lie detector machine?
Although polygraphs are consistently famous as lie detectors, they forbiddance really discover lies straightforwardly. Most modern polygraphs measure the respondent's courage rate, breathing rate and sweaty while they are requested agreed/no questions.

3. discuss the development of polygraph machine
Answer:
A history of the polygraph
The first polygraph was created in 1921, when a California-based policeman and physiologist John A. Larson devised an apparatus to simultaneously measure continuous changes in blood pressure, heart rate, and respiration rate in order to aid in the detection of deception (Larson, Haney, & Keeler, 1932; McCormick, 1927). The invention of the polygraph cannot be, however, attributed to a single individual. Seven years prior, in 1914, Italian psychologist Vittorio Benussi had published his findings on the respiratory symptoms of the lie (from German: ‘Die Atmungssymptome der Lüge’), and it was American psychologist, lawyer, and author William M. Marston who invented the discontinuous systolic blood pressure test for the detection of deception in 1915 (Alder, 2002), which, when taken together, formed the basis for Larson’s polygraph.
The polygraph first came into significant contact with the legal system in 1923, when Marston attempted to have the results of a polygraph test admitted as evidence (the United States v. Frye, 1923). The court rejected the results as evidence, stating that ‘while the courts will go a long way in admitting experimental testimony deduced from a well-recognized scientific principle or discovery, the thing from which the deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs’ (the United States v. Frye, 1923. p. 1). This became known as the Frye Standard, which would govern the admissibility of expert testimony in US courts until well after the end of the Cold War.1
The vast majority of early polygraph research was conducted by John Larson, who worked for the Berkley, California, police department throughout the 1920s. Berkley Police Chief August Vollmer saw Larson’s work as a means to significantly improve the effectiveness of his department and thus allowed Larson to test and refine his polygraph through work on real cases (Carte & Carte, 1975). Vollmer’s focus on the polygraph’s practical value over any other concerns was something that would come to be a common stance within law enforcement in the US.
Larson’s early work benefited from the aid of his then-protégée Leonarde Keeler, who is often credited with the creation of the first polygraph testing procedures, such as the Relevant/Irrelevant Question Technique (Keeler, 1930). Keeler was responsible for making the polygraph apparatus portable and was the first to add the galvanic skin response (GSR) channel to it in 1938, based on the work of Fordham University Graduate School psychologist Reverend Walter G. Summers (Summers, 1936). Keeler, however, did not share Larson’s dedication to academia but rather desired financial and commercial success. To this end, Keeler patented his polygraph, became one of the first to found a ‘polygraph school’, and went so far as to appear as himself in the 1948 noir film Call Northside 777 (Alder, 2007; Matte, 1996). Prior to his death in 1949, Keeler contributed greatly towards the popularity of the polygraph, much like Marston did, but also became one of the first of many to focus purely on the polygraph’s lucrative potential at the expense of any academic contribution. Following Keeler’s death, the polygraph’s history continued unabated with John E. Reid, who is known for the controversial ‘Reid Technique of interviewing/interrogation (Gudjonsson, 2003; Johnson, 2003; Kassin & Gudjonsson, 2004). Reid did not only establish his own polygraph school but developed the CQT, the polygraph testing procedure that replaced Keeler’s Relevant/Irrelevant Question technique as the most widely used technique, which it remains to date (Raskin & Honts, 1987; Reid, 1947, Wilcox & Madsen, 2009).
The development of new testing procedures and the increasingly widespread use of the polygraph2 were not matched by academic progression in the field of deception detection. Only a small number of those involved in polygraph testing (e.g. Larson et al., 1932) sought peer-reviewed publication of their work or attempted to intentionally test the effectiveness of polygraph examinations or their underlying theories (e.g. Landis, 1925). This acted as the basis for mounting criticism of the polygraph research later on, on the grounds of a lack of scientific rigor within the early polygraph studies.
It was not until 1965, 41 years after the Frye standard was established, that the first empirical review of the polygraph was conducted. This occurred when a proposal to use the polygraph to screen federal employees prompted the US Committee on Government Operations to evaluate the relevant evidence. It concluded: ‘There is no lie detector, neither man nor machine. People have been deceived by a myth that a metal box in the hands of an investigator can detect truth or falsehood’ (US Congress, 1965, p. 1).

Answer:
There have been several reviews of polygraph accuracy. They suggest that polygraphs are accurate between 80% and 90% of the time. This means polygraphs are far from foolproof, but better than the average person's ability to spot lies, which research suggests they can do around 55% of the time.

14. what are the effects and alcohol on polygraph test?
Answer:
Eighty male volunteers participated in an analogue study of the effects of alcohol intoxication at the time of a crime on the physiological detection of deception using control question and guilty knowledge techniques. Sixty-four of the subjects committed a mock crime and half of these were intoxicated during the crime. Sixteen subjects committed no crime and served as innocent controls. We found that intoxication at the time of the crime had no significant effect on polygraph test outcomes, although it did affect anticipatory arousal before the crime and subsequent memory for crime details. Manipulations designed to influence memory for crime details and arousal during the crime had differential effects for the two polygraph tests. On the guilty knowledge test, primed subjects who rehearsed specific details following the crime were more detectable than unprimed subjects. On the control question test, primed subjects were also more detectable, but only when arousal during the crime was high.

Answer:
Most psychologists agree that there is little evidence that polygraph tests can accurately detect lies.
Answer:
They estimate the accuracy of the polygraph to be 87%. That is, in 87 out of 100 cases, the polygraph can accurately determine if someone is lying or telling the truth. That sounds pretty impressive, but it is important to keep in mind that the polygraph is failing 13% of the time.

17. what is the difference of the analog polygraph and modern polygraph?
Answer:
Computerized Polygraph
Since 1993, the computerized polygraph machine has replaced the analog machine. Just like the analog polygraph, the computerized polygraph measures a person's heart rate, leg movements, sweating and other physiological responses. It is quite comprehensive and tells if a person is not telling the truth. The main difference between the analog and computerized polygraph is that the computerized makes its recording on a computers hard disk, which can be viewed on a screen or printed out.
