This page will remain under construction for some time. Many of these materials will require the Macromedia Flash plugin for your browner, or the ubiquitous Adobe Acrobate Reader or plugin.

Warning: If you are subject to polygraph testing requirements, you would be better off not reading these materials as attempting to educate yourself regarding the polygraph technique is unlikely to improve your test results - even if you are telling the truth.
