Chapter II Flashcards
It is the basis and goal of all criminal investigation.
“search for truth”
He defined “search for truth.”
Dr. Hans Gross
Gross stated, a large of the criminal work is
nothing more than a battle against ______.
lies
Scientists who
contributed in the development of polygraph
- Angelo Mosso
- Cesare Lombroso
- William Moulton Marston
- Dr. John A. Larson
- Leonarde Keeler
- John E. Reid
- Vittorio Benussi
- Harold Burtt
- Luigi Galvani
- Jacques-Arsene D’arsonval

- Harold Sticker
- Otto Veraguth
- Francis Franke
He stated that fear
influenced the heart and could be used as a basis for detecting deception.
Angelo Mosso
He uses
“Sphygmanometer” and scientific radio to study fear, there is however, no evidence
that he ever put this into practice.
Angelo Mosso
He developed the mechanical device known as the “Scientific Cradle” often
called “Mosso’s Cradle”.
Angelo Mosso
This device was nothing more than a balanced table-like
platform, mounted on a fulcrum.
“Scientific Cradle” or “Mosso’s Cradle”
He is an Italian scientist who employed the first
scientific instrument to detect deception known as Hydrosphymograph.
Cesare Lombroso
This instrument measures changes in pulse and blood pressure when suspects were
questioned about their involvement of a specific offense.
Hydrosphymograph
He modified the plethysmograph thus inventing a more modern device called hydrosphygmograph.
Cesare Lombroso
He was accorded the distinction of being the first person to utilize a scientific
instrument successfully in the detection of deception.
Cesare Lombroso
Father of Lie Detection
William Moulton Marston
He dealt with the Sphygmomanometer and made researches on the usefulness of Sphygmomanometer in detecting lies, which was used to obtain periodic discontinuous blood pressure readings during the course of an examination. He recorded the respiration and noted the time of subject’s verbal responses.
William Moulton Marston
This was used to obtain periodic discontinuous blood pressure readings during the course of an examination.
Sphygmomanometer
He experimented with galvanometer to record skin resistance changes and a
gripping device to record tension.
William Moulton Marston
He was the first to use polygraph in espionage case in 1917-1918.
William Moulton Marston
He deviced an instrument that records both
blood-pressure and galvanic skin response. He introduced this machine to the
University of California and first applied in law enforcement work by the Berkeley
Police Department under its nationally renowned Police Chief August Vollmer.
Dr. John A. Larson
Who was the nationally renowned police chief of Berkeley Police Department?
Police Chief August Vollmer
He designed the first two recording channel polygraph in the history. The first
mechanical form of the present-day polygraph consists of two recording components
and that is the cardiosphymograph and the pneumograph.
Dr. John A. Larson
The first mechanical form of the present-day polygraph consists of two recording components and that is the ____________ and the _____________.
cardiosphymograph; pneumograph
He improves Larson’s Apparatus and in 1949 he
invented the “Keeler Polygraph”. He also designed a metal bellows and a
kymograph that pulled at a constant speed, a chart paper under the recording pens
from a roll of chart paper located inside the instrument.
Leonarde Keeler
He designed a special chair equipped with metal
bellows for recording unobserved muscular activities of the arms, thighs and feet,
located on the arm of the chair and on the seat, this transmit singular muscular
activity to the recording polygraph.
John E. Reid
He introduced the first recording channel instrument to be developed. This
instrument is excellent for detecting deceptions because it does not only have a
recording pen for cardiosphymograph, pneumograph and galvanograph but also it has
the muscular movement pen for the arms and thighs.
