Polygraph / Lie detector tests

Recently in 2006, a man serving a life sentence in a Western Australian gaol, Andrew Mallard (no relation to the owner of Lyonswood, Warren Mallard) was released when it was found that much of the evidence against him was fabricated. This man was tested twice by Lyonswood’s Polygraph Examiners Bill Glare and Steve Van Apren and found on both occasions to be telling the truth. We used two different examiners and both found that there was no deception. This is a well documented case and material on this case can be found at

THE AFOREMENTIONED DATA ARE THE MOST COMPELLING EVIDENCE OF THE LEGAL ACCEPTANCE OF THE USEFULNESS OF THE POLYGRAPH FOR ASSESSING THE TRUTH AND DECEPTION.Physiological measurements for the detection of deception have been developed and subjected to scientific evaluation for almost one hundred years and the most commonly used polygraph tests and instruments are based on generally 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 in the autonomic nervous system. These reactions include skin resistance (palmar sweating), increased blood pressure, pulse rate and decreased/increased respiratory activity, all of which are measured with modern polygraphs. Attempts at faking are well known and readily understood by the experienced polygraph examiner.

PEOPLE DON’T BEAT THE POLYGRAPH MACHINE.
THEY BEAT THE POLYGRAPH EXAMINER.

THAT IS WHY IT IS IMPORTANT TO HAVE A COMPETENT QUALIFIED EXAMINER.
BEFORE TAKING A TEST MAKE SURE YOU OBTAIN THE GENUINE QUALIFICATIONS OF THE EXAMINER.

LYONSWOOD INVESTIGATION’S POLYGRAPH EXAMINERS ARE QUALIFIED IN THIS FIELD AND ARE MEMBERS OF THE AMERICAN POLYGRAPH ASSOCIATION. They are qualified through the Western Oregon University as Certified Polygraph Examiners and have trained with the Los Angeles Police Department, U.S. Secret Service, Los Angeles County Sheriff’s Department and the FBI.

WHAT HAPPENS DURING A POLYGRAPH TEST?

• Usually there are three parties to a polygraph test. The examiner and the two individuals that need to resolve their issues. Usually just one person undertakes a test,  it is also possible to test two persons however, not in the one test.  In the first instance an interview takes place between all parties so that the examiner understands the issues. Once it is determined who is going to undertake the polygraph examination, the questions are formulated and agreed upon and the polygraph is explained to all parties.

• The person undertaking the polygraph is then connected to the polygraph machine and then the testing and questioning process begins. At the completion of the test, a period of time is taken to analyse the print out from the polygraph machine and to correlate the questions asked with the responses recorded upon the polygraph machine. This is a most important process.

• Once the responses have been analysed, the results are then verbally provided to the party/ies. At the completion of the polygraph test and approximately three working days later, a written report of the findings is compiled and provided to the authorised party. The test process takes approximately three hours so allow adequate time for the procedure.

HOW DO I ARRANGE A POLYGRAPH TEST?

• To arrange a test it is preferable that the issues you need to resolve are thought out carefully and a list of questions that you need the answers to, written down.

• Once you have these questions prepared, call Lyonswood Investigations on (02) 9819 6833 and arrange to make an appointment for the test to be conducted.

• If you decide to have the test carried out you will need to secure the appointment by making a deposit of 50% in advance with Lyonswood Investigations which is non refundable. Lyonswood Investigations accepts Bankcard, Visa card, MasterCard and cash. It does not accept cheques or other cards. The balance of the total polygraph fee, is payable on the day of the polygraph immediately preceding the test. A receipt for the full amount (including GST) will be issued. In the event the agreed appointment is not kept, the deposit amount will be forfeited. In the event that another appointment is made for a polygraph examination and kept, the forfeited deposit will be considered for reimbursement minus some charges incurred in the cancellation.

MEDICATION
If you are taking any medication and you are going to be polygraph tested we will need to know in advance what that medication is. This may alter whether we can in fact conduct the polygraph.

PACEMAKERS
If you are fitted with a pacemaker we need to know this in advance as it will definitely effect the results of the polygraph and may preclude a test being conducted.

PREGNANCY
If you are pregnant and about to undergo a polygraph we need to know as the foetal heartbeat can affect the outcome of the test and the wearing of a blood pressure band can also affect the flow of blood.
