NPC QUICK REFERENCE - COMPARISON QUESTIONS
Model NPC-QR3
Price: $ 8.00*
Developing a comparison question that is appropriate to an examinee and case is perhaps the most challenging aspect of polygraphy, and its importance cannot be overstated. This guide is designed to be a handy source to the competent polygrapher in this crucial process.
There is more than one school of thought about comparison questions; exclusionary, non-exclusionary, directed or probable lie. All of these types are included in this guide so that examiners may choose those that fit their methods, and also to acquaint examiners with those in which they are less familiar.
