The study evaluated the questions used in a polygraph test. It focused on criminal investigative tests (also referred to as “criminal specific tests”), those tests conducted when a criminal offence has been committed and the in-test phase questions (those test questions asked to address what is under investigation). To conduct a successful criminal investigative polygraph test, it is important that polygraphists be familiar with the types of questions used in a polygraph test and how they should be formulated for more effective outcomes. The recognition of these questions and how they are formulated is of utmost importance as it determines the success of the criminal investigative polygraph test. === Police Practice === M.Tech.
