His first apparatus, he referred to as a "Cardio-Pneumo Psychogram," consisted of a modification of an Erlanger Sphygmomanometer. Its reliability is often debated, but the polygraph measures a subjects physiological activity like blood pressure, pulse, respiration, and skin conductivity to try to determine if they are answering questions honestly.

The NAS concluded that the polygraph "may have some utility but that there is "little basis for the expectation that a polygraph test could have extremely high accuracy". It would be John Augustus Larson, a Californian police officer, who invented the polygraph in 1921. [93] Marston's main inspiration for the device was his wife, Elizabeth Holloway Marston. Born in Nova Scotia in 1892, John Augustus Larson became interested in forensic science and went on to receive his Ph.D. in physiology at the University of California, Berkeley around 1919.. RT based tests differ from polygraphs in stimulus presentation duration, and can be conducted without physiological recording as subject response time is measured via computer. The subjects were convicted of assault. The Department of Defense ordered its use be limited to non-US persons, in overseas locations only.
