  • james mackenzie's polygraph

    james mackenzie's polygraph
    invented polygraph that used a clockwork mechanism for the paper-rolling and time-marker movements and it produced ink recordings of physiological functions that were easier to acquire and to interpret
    environmental impact: paper= trees being cut down, one tree fallen can take out an entire echosystem.
  • Italian psychologist Vittorio Benussi

    Italian psychologist Vittorio Benussi
    method for calculating the quotient of the inhalation to exhalation time as a means of verifying the truth and detecting deception in a subject. evniornmental impact: none..
  • Dr. William Moulton Marston, an American attorney and psychologist

    Dr. William Moulton Marston, an American attorney and psychologist
    Dr. Marston's technique used a standard blood pressure cuff and a stethoscope to take intermittent systolic blood pressure readings of a suspect during questioning for the purpose of detecting deception.
    environmental impact: none seen...
  • John A. Larson, a Canadian psychologist

    John A. Larson, a Canadian psychologist
    added the item of respiration rate to that of blood pressure. Larson was the first person to continually and simultaneously measure changes in a subject's pulse rate, blood pressure and respiratory rate during an interrogation. enviornmental impact: more material is added to the pollution from factories and buildings destroying land
  • Leonarde Keeler

    Leonarde Keeler
    used inked pens for recording the relative changes in a subject's blood pressure, pulse rate and respiratory patterns In 1938, Leonarde Keeler further refined the polygraph when he added a third physiological measuring component
    environmental impact: destroys resourses to make ink and other addatives needed to make machine
  • Today, Leonarde Keeler is known as the father of polygraph

    some believe that keelers design is now just a less modified version of what we have now, we run off his absic idea environmental impact: none really seen..
  • John E. Reid

    John E. Reid
    developed the Control Question Technique (CQT), a polygraph technique that incorporated control questions (comparison) which were designed to be emotionally arousing for non-deceptive subjects and less emotionally arousing for deceptive subjects than the relevant questions previously used.
    environmental impact: changes how a person is feeling which changes the mood in the environment thats surrounding said person
  • world's first polygraph school

    Leonarde Keeler founded the world's first polygraph school — the Keeler Polygraph Institute — in Chicago, Illinois. Environmental impact: building the building destroys the land and ruins an decosystem that was in the place before the building
  • Cleve Backster

    quantification system of chart analysis, thus making it more objective and scientific than before
    environmental impact: More machinery adds to the destruction of resources.
  • Dr. Joseph F. Kubis

    potential computer applications for the purpose of polygraph chart analysis
    environmental impact: trees cutting down, disrupts the echosystem in the forest the tree was brought from
  • Drs. John C. Kircher and David C. Raskin

    developed the Computer Assisted Polygraph System (CAPS), which incorporated the first algorithm to be used for evaluating physiological data collected for diagnostic purposes. environmental impact: the technology to produce the parts affect the environment by pollution or building the buuildings to make the product
  • computer era

    the polygraph made its official entrance into the computer age.
    impact: is more biproduct and waste coming from the factories producing the machine
  • Period: to

    timespan of polygraph technology
