• What is a Polygraph?
Polygraph comes from the Greek words: Poly (many) and Grafos (writings); therefore, it means "many writings." The name refers to the manner in which selected physiological activities are simultaneously recorded using conventional instruments, also known as analog instruments, or computerized polygraph instruments. We Use the latest technology: COMPUTERIZED POLYGRAPH which is most reliable
The polygraph instrument is a scientific instrument, which collects physiological data from at least three systems in the human body, for example: two convoluted rubber tubes that are placed over the examinee's chest and abdominal area will record pneumonal or respiratory activities. Two small metal plates, attached to the ring and index fingers, will record sudoriferous or sweat gland activity and a blood pressure cuff placed around the upper arm will record cardiovascular activity (blood volume and pulse rate). In addition, the examiner uses a sensor activity pad for the purpose of monitoring body movements.
• How Does the Polygraph Work?
All people have an emergency, or survival system, commonly known as the “fight or flight” system. Any time and individual perceives danger, this system is automatically activated, causing sudden changes to take place within the body to better prepare the person to meet the threat. Before the polygraph examination, the examiner will and should review all the questions to be asked with the examinee.
So, the examinee will know exactly that he/she is going to be asked during the test. If, during the test, the examinee is asked a questions he/she has decided to lie to, his/her brain will perceive this question as a threat; therefore, the body’s emergency system will activate. The examinee will experience sudden changes taking place within his/her body, and simultaneously the polygraph instrument will permanently record them. For the examinee’s protection, the examiner will run more than one graph (asking the same questions more than once). This is to ensure that any changes taking place in the examinee’s body are due to the adrenaline rush caused by lying to a specific question, and is not exclusively due to a coincidental physiological change.
Nervousness won't change or affect the results of the Polygraph examination because it remains steady during the exam.
• How Accurate is the Polygraph?
Polygraph as a scientific methodology and can achieve accuracy rates of 95% or better in determining accuracy on non deception (truth) or deception (lie) when administered by properly certified professional applying professional APA standards. It is worth mentioning that a person cannot beat or deceive a polygraph instrument but rather could beat the polygraph examiner by the single fact that perhaps the examiner does not have the preparation required by the standards of the profession. Additionally, polygraphists must receive training periodically to maintain their status as members of the APA and to remain updated in the profession.
• Who Uses Polygraph Examinations?
The three most important segments of society that use the polygraph include law enforcement agencies, the legal community, and the private sector. These are further described as follows:
Law Enforcement Agencies – Federal Law Enforcement Agencies, State Law Enforcement Agencies, and Local Law Enforcement Agencies such as Police and Sheriff’s Departments. Also, Probation or Parole.
Legal Community – U.S. Attorney Offices, District Attorney Offices, Public Defender Offices, Defense Attorneys, Parole & Probation Departments. Courts when requested by a Judge.
Private Sector – Companies and Corporations under the restrictions and limitations of the Employee Polygraph Protection Act of 1988 (EPPA)
Private Citizens – They would tend to use the polygraph in matters not involving the legal or criminal justice system.
Attorneys – They usually use polygraph in civil litigation & criminal cases.
• Steps Associated with the Polygraph Test
An appropriately performed exam must consist of the steps listed bellow. If any of these steps are not conducted in the process, the results cannot be relied upon.
Introduce and explain procedure and equipment.
Collect background information and medical history of the examinee.
Discuss case facts and obtain a statement.
Examiner designs questions and reviews them with subject.
Run a pretest or stime test followed by the actual polygraph charts.
Chart analysis by examiner.
THE AVERAGE TIME REQUIRED FOR A POLYGRAPH TEST IS ABOUT 90 MINUTES.
Consequently, any examiner who claims that an effective polygraph test can be run in less time is not providing exams to any adequate standard of practice, and cannot ensure reliable results; which can have serious legal consequences.
