Depending on the complexity of the case and the issues being tested a polygraph test usually takes up to two hours. Our Platinum package which includes both the EyeDetect and Polygraph test combined can take up to 2.5 hours. The EyeDetect or Polygraph alone (Basic and Silver packages) usually take approximately 2 hours.

The science of polygraph testing is based on far more than the technology of the polygraph instrument. The interview skills of the examiner are paramount in ensuring an effective testing process free of ambiguity or doubt.

Firstly the Examiner must obtain a comprehensive brief which identifies the circumstances, issues, allegations and facts in dispute.

Secondly, the examiner reviews the material, and formulates test questions in such a way as to elicit clear and complete responses. It is critical not to ask questions which can result in partial answers. In this stage the material gathered from the Pre-test brief is broken down into its component parts and matched to the appropriate questions.

Thirdly, the examiner takes the participant into the testing phase. This is where the sensors are attached to the examinee and the recording process commenced. The questions are read to the examinee several times during the recording process. Typically a minimum of three charts are recorded. After each question is asked a 25 second period follows whereby the instrumentation records autonomic responses to each question.

Finally the data collected from the polygraph charts is printed and the results numerically scored. The test results are then given to the relevant parties. Four final results are possible:

Truthful, Deceptive, or Inconclusive In order to reduce distractions for the examinee polygraph exams are conducted in private with no other persons permitted in the examination room (other than an interpreter if required).

EyeDetect is the world’s first non-intrusive lie detection technology that detects deception in 15-30 minutes with 90% accuracy. We are the first company to introduce this sophisticated technology into Australia and are the certified Australian Premium Service Provider in partnership with EyeDetect.

Scientific research has proven that the brain and eyes respond to deception. The greater the consequences of the lie, the greater the cognitive load which affects the eyes. Using a sophisticated infrared eye scanner, laptop and proprietary algorithms EyeDetecttelemetry measures subtle changes in pupil diameter, eye movement, reading behaviour, blink rate, eye fixations and several other parameters at 60 measurements per second per eye or a total of 350,000 computations during one examination.

When the test is finished responses to questions and eye measurements are uploaded to a secure web server for immediate scoring within minutes. The scoring process is evaluated by propriety algorithms that cannot be manipulated or influenced by human bias or prejudice. A credibility score calculates the probability of truth or deception

This is the future of lie detection.

A polygraph test records physiological responses whilst the examinee answers a series of questions.

Polygraph techniques are derived directly from basic scientific principles and research in psychology and human psychophysiology. Physiological measurement techniques for the detection of deception have been developed and subjected to scientific evaluation for almost 100 years.

The most commonly used polygraph tests are based on widely accepted scientific principles. It is well established that certain stimuli, such as questions to which a person is lying during a polygraph test, produce involuntary changes that are controlled by the autonomic (sympathetic & parasympathetic) nervous system. These reactions include increased skin conductance (palmar sweating), increased blood pressure and decreased respiratory activity.

Considerable scientific research has demonstrated that the pattern of physiological changes during a polygraph test provides the basis for making highly accurate inferences concerning truth or deception. The vast majority of scientific evidence supports the reliability and accuracy of comparison question tests for assessing credibility.

In the past 75 years, over 250 studies have been conducted on the validity, accuracy and reliability of polygraph testing (American Polygraph Association 1996 Polygraph Issues & Answers). Based on twelve separate studies involving 2,174 real cases since 1980, evidence suggests that qualified field polygraph examiners are 98% accurate in their overall decisions (Ansley, N. 1990 The validity and reliability of polygraph decisions in real cases). This level of confidence is well within the guidelines for scientific measurements in other fields.

One of the misconceptions about testing is that several issues and questions can be covered in the one test. This is generally not the case.  When you have multiple issues and questions in the one test it reduces the accuracy of the testing format and can even produce false positives or false negative results (calling a truthful person deceptive and a deceitful person truthful).  Also if you have several questions in the one test they compete against each other which means you can reduce the accuracy to under 50% or even less.

In any testing process we need to demonstrate internal reliability and construct validity to ensure the highest accuracy and testing standards. Standardisation is paramount. We also need to ensure that the testing procedure is robust and complies with scientifically validated testing formats. If these conditions are not met then the accuracy and reliability of the testing becomes diluted and questionable. For this reason the tests are standardised in a format that can deliver a high degree of confidence in the outcome of results.

Introducing several issues in the one test creates a situation where questions start competing against each other which weakens the accuracy of the test. This situation should be avoided at all costs. Multiple issues can be tested but they need to be conducted on separate tests (discounts apply for multiple tests). A qualified examiner however can formulate a single question that will often cover the central theme or major issue.

Example 1 In the case of a theft of $20,000.00 from a safe located in an office a number of questions may arise such as:

Was the suspect in the area at the time of the theft Did the suspect go near the safe Did the suspect open the safe door Did the suspect use a key to open the safe Did the suspect take the money Even though these questions are important they are peripheral to the main issue as to whether the suspect took the money or not. In this case a single direct question such as “Did you take the money from the office safe last Thursday?” would resolve the above issue.

Example 2 In the case where a wife suspects her husband of engaging in a sexual relationship with another woman a number of issues may be raised including:

Has her husband lied about where he has been Has her husband been seeing another woman Has her husband been behaving in a strange or unusual manner Has her husband been making secret phone calls Has her husband been required to work weekends Has her husband been working later than usual etc Although these changes in behaviour are important the issue could be resolved with a single direct question such as: “Have you had sexual intercourse with any other woman since you married?

It is important to avoid asking two issues within the same question such as: “Did you steal the $2,000.00 cash from the safe and the printer from the manager’s office?”

Separate issues can not be asked within the same test. For example you cannot ask: “Other than Susan did you have sexual intercourse with anyone else?” together with “Have you ever used any type of illegal drug?” in the same test. Both these issues are separate matters and can cause what is refereed to as anti-climax dampening. If the examinee decided to lie to both questions one question may overpower the other and produce a non deceptive response even though the examinee is lying.

In the example above a person may perceive the sexual intercourse question to be more threatening than the illegal drug question or vice versa. To alleviate these problems it is important not to mix separate issues in the one test.

Several issues can be examined but they have to be addressed in separate exams.

No. A polygraph records changes in blood pressure, pulse rate, pulse strength, galvanic skin conductivity and reactivity (sweat gland activity), and changes in pneumographic patterns.

It is expected that all people who undergo a polygraph test will be nervous whether they intend to answer questions truthfully or not. As a result we calibrate the instrumentation to work off that heightened level of nervousness or anxiety. An examiner will look for action specific responses over and above the examinee’s heightened level of nervousness or anxiety.

Typically an examinee remains nervous throughout the entire testing process not at one individual question. If nerves affected the result of a polygraph test then nobody would ever pass a test!

We first conduct a calibration test to demonstrate to the examinee that we can differentiate between a known truth and a known lie even before the test commences.

No. Generally it is the role of the courts and juries to determine guilt or innocence not a polygraph examination result.

Polygraph tests are not intended to be a means for delivering a legal verdict, but rather an invaluable investigative tool. Polygraph testing has allowed investigators to either exonerate or implicate suspects or witnesses.

Polygraph testing has saved investigators and companies thousands of dollars in investigative costs and resources by narrowing the focus of enquiry and providing further investigative leads.

It is important that you choose a polygraph examiner who has been professionally trained, accredited and certified. Every qualified examiner must reach certain competencies before certification can be awarded. After training, each qualified examiner must serve an “internship” whereby their work is quality controlled and evaluated to ensure that the appropriate testing formats are used and that questions are properly formulated according to current testing methodology.

If you have spoken to someone who represents themselves as a qualified polygraph examiner ask them where they trained and what polygraph qualifications they hold.

About Our Examiner

Steve van Aperen

Polygraph Examiner BA. (Criminal Justice Admin.) Grad. Dip. (Security Mgmt) Director, Australian Polygraph Services, Member American Polygraph Assoc.

Television host of the new crime show “The Hunters” 

In 1996 Steve was the first Victorian Police Officer to graduate from Western Oregon University USA as a certified polygraph examiner. After graduating Steve trained with and examined polygraph testing formats and behavioural interview techniques utilised by the Los Angeles Police Department (LAPD) Polygraph Unit, US Secret Service, Los Angeles County Sheriff’s Office and the Federal Bureau of Investigation (FBI). Steve is now the Managing Director of Australian Polygraph Services and consults his services to the public, government and corporate organisations worldwide.

Steve was also consulted by the South Australian Police to set up their Pre-employment polygraph screening program in 2008. Australian Polygraph Services has since conducted a number of pre-screening polygraph tests on selected applicants as part of their recruitment process.

Steve also consults his services to the Victoria Police homicide squad and the South Australian Police Major Crime Squad and has conducted polygraph testing for 87 high profile homicide cases and two serial killer investigations. Steve has also conducted a number of other high profile media polygraph tests and interviews

People don’t beat a polygraph test they beat the examiner conducting the test. This is why it is imperative to ensure that the examiner conducting the test is certified and qualified.

A polygraph is simply an instrument that records changes in autonomic reactivity when confronting a given stimulus (question). If a person engages in behaviours that are designed to distort the polygraph tracings then it is the job of a competent and qualified examiner to identify and determine when this is occurring.

In most cases it is easy for a qualified examiner to determine when an examinee is attempting to influence the outcome of the exam. Although some parameters can be consciously controlled these are usually easily detected.

Typically truthful examinees are cooperative and follow instructions whereas deceptive examinees will attempt to engage in certain behaviours in an effort to distort the tracings. When such behaviours are identified three verbal warnings are given. If this behaviour continues the test is stopped and a Purposeful Non Cooperation (PNC) result is returned.
