What makes Polygraph Examination essential?

During a polygraph examination, also known as a lie detector test, several physiological indicators such as blood pressure, pulse rate, respiration rate, and skin conductivity are measured and recorded. At the same time, a person is asked and answers a series of questions. Based on the fluctuation of these physiological indicators, the device or procedure determines whether the person is speaking the truth or not, and the results are reported.

There is a widespread notion that deceitful replies will result in physiological reactions that can be distinguished from those associated with non deceptive responses, which is the basis for using the polygraph.

Of what use is a polygraph examination?

  • What is the mechanism of action of a polygraph machine
  • what questions are often asked during a polygraph test, and
  • what is the purpose of a polygraph examination are all topics that people commonly ask?

Mechanism of action

In combination with blood pressure and heart rate, the equipment detects changes in the subject’s breathing rate and the amount of sweat produced. It is believed that a person who is lying has involuntary physiological reactions that may be detected by a polygraph device, which is why this test is used.

Increased blood pressure and sweat are among the changes that occur. Rapid breathing and pulse are also among them. A polygraph examiner from Oklahoma City relies on in-depth knowledge of this process to perform their duties.

Frequently asked questions during a polygraph examination?

During the polygraph examination, the examiner has a broad range of questions to ask the subject. This set of questions will consist of three to four pertinent questions, with the remaining consisting entirely of control questions. All of the questions are either “yes” or “no” in nature.

Responses to inquiries that solicit views, sentiments, or mindsets are not utilized since they cannot be classified as either honest or untruthful. Likewise, the answers cannot be separated into truthful or misleading categories. The following are some samples of the most often asked questions during a polygraph examination.

  1. Is your name Paul?
  2. Are you 20 years of age?
  3. Were you born in the year 1997?
  4. Are you engaged in this activity?
  5. Is your dog’s name Frank?
  6. Is your birthday on February 20th?
  7. Do you rent an apartment?
  8. Do you know about the said incidence?
  9. Do you live at the said address?
  10. Are you guilty of the act as charged?
  11. What day of the week is today?

A handful of those questions are purposely deceptive in their answers. Consider the inquiry concerning one’s age and the year of one’s birth as an example. An individual who is 20 years old now would not have been born in 1997. It is necessary to include these questions to identify both correct and erroneous replies.
