There's no sense
to overpay thousands of dollars Depending on the complexity of the case and the number of issues being tested a polygraph examination generally takes 2-3 hours. A lie detector examination consists of three phases: the pretest interview, the collection of charts, and the analysis of the polygraph charts. In the pretest interview phase, the polygraph examiner will complete the required paperwork and discuss the test questions so that the examinee fully understands each question in advance of taking the polygraph examination. The examiner will also explain the polygraph testing process and answer any questions or concerns. The collection of charts phase takes place in a quiet room with no one but the polygraph examiner and examinee present to prevent distracting the examinee. The polygraph examiner will attach sensors to the subject and ask "yes" or "no" questions that have previously been discussed. Data is collected from the sensors in the form of polygraph charts. In the last phase, the examiner will analyze the charts and render an opinion as to the truthfulness of the person taking the test. |
