Lie Detector Test

There are many reasons why people require a polygraph test to be conducted, much of this comes down to the fact, some people can lie a little too easy, and it becomes second nature.

What is a Polygraph?

A polygraph is a real name for a “Lie Detector Test.” When a person is connected to the machine, it reads physiological responses to questions and stimuli. From here, the licensed investigator can tell if they are telling the truth or not. This test cannot be performed by anyone. First you have to understand how to read the machine responses, and second, for it to be ethical and legal a polygraph test has to be conducted by a licensed operative.

What Happens in a Polygraph Test?

A polygraph can take years of training and experience to do correctly. A polygraph test can take from 2 to 3 hours depending on what questions have to be asked.

A licensed investigator will break the test down into three parts which are as follows:

 

  • Part One - This pre-test helps to determine whether or not the person in question can be polygraphed or not.
  • Part Two – This is the part where the licensed investigator will test reactions to questions where they monitor the results for positive or negative reactions. Questions can be asked multiple times to see if the results are the same in each instance.
  • Part Three – The investigator will check all the results and come to a conclusion on their findings. From the answers given, they will be able to see if the person in question was lying or being truthful when they were providing their responses.

When individuals deal with cases which involve child custody, they can become delicate and very sensitive. Each case can be very different and can include a situation where child support, runaway children or alimony is involved.

A lot of these child custody cases and investigations come toward the end of a relationship which in itself is a very sensitive subject and frustrating time. Private Investigators of Las Vegas understand all of this, and as a professional company make sure the best results are achieved for everyone who is involved.

How do the Investigator Know?

When answers are given, the body reacts in many ways. When a person is lying, their breathing can change, or their sweat glands become more active along with higher blood pressure. All of these changes are monitored during a polygraph test by the licensed investigator in Las Vegas.

It is the “consistent significant reaction” that determines the result, and this is the same when a particular question is asked.

One thing to note is, the test only shows what the person being tested believes to be true. This can be very far from what did indeed happen.
