What is a Polygraph?

The term “polygraph” literally means “many writings.” The name refers to the manner in which selected physiological activities are simultaneously recorded. Polygraph examiners may use conventional instruments, sometimes referred to as analog instruments, or computerized polygraph instruments.

It is important to understand what a polygraph examination entails. A polygraph instrument will collect physiological data from at least three systems in the human body. Convoluted rubber tubes, also known as pneumo tubes, are placed over the examinee’s chest and abdominal area that will record respiratory activity; two small metal plates attached to the fingers will record sweat gland activity; and a blood pressure cuff will record cardiovascular activity.

TRUTH OR DECEPTION?

Polygraph examinations are used to verify the truth and determine deception. In both civil and criminal matters, polygraph examinations can enhance an investigation by helping to clear the innocent and identify the guilty.

A few of the areas in which a polygraph can be valuable include:

  • Criminal Defense
  • Identifying a Guilty Party
  • Clear the Wrongfully Accused
  • Verify Information and Statements
  • Violent Crimes
  • Property Crimes
  • Sex Crimes & Allegations of Sexual Misconduct
  • Sexual Harassment
  • Narcotics Investigations
  • Domestic Disputes
  • Infidelity Issues
  • Insurance Fraud
  • Allegations of Child Abuse
  • Allegations of Official Misconduct
