Polygraph Information
by Kaitlyn Guenther
This is a school project that I did for my Forensic Science class in grade 10. All of the information is about polygraph machines.
Polygraph, meaning "many writings", is derived from the Greek language. In Greek the word "poly" means "many", and the word "graph" means "writings".
About the Polygraph Machine:
- History of the Polygraph Machine
- The Polygraph Machine
- Polygraph Testing
- Polygraph Test Results
- The Accuracy of Polygraph Testing
- The Exoneration of
Jerry Watkins
- Signs That Indicate a Person is Lying
