FREE CPE Testing Procedures Questions and Answers
Which physiological responses are typically monitored during a polygraph test?
During a polygraph test, the primary physiological responses monitored are heart rate, blood pressure, and respiration. These indicators are believed to change when a person experiences stress, anxiety, or deception.
What is the primary purpose of the "control" questions in a polygraph test?
"Control" questions are used in a polygraph test to establish baseline physiological responses. These questions are designed to produce a reaction that is typical for the individual, making it easier to compare against responses to "relevant" questions.
How does a polygraph examiner determine if a person is being deceptive?
Polygraph examiners compare physiological responses (heart rate, blood pressure, respiration) to relevant questions and control questions. A significant change in these responses is often interpreted as an indication of stress or potential deception.
What type of questions are typically asked during a polygraph test?
During a polygraph test, the examiner asks "relevant" questions that are directly related to the matter being investigated. These questions are designed to gauge physiological responses linked to truthfulness or deception regarding the specific issue at hand.
What is the purpose of a "stim test" or "stimulus test" in polygraph testing?
A "stim test" is a preliminary test where the subject is asked a series of questions designed to provoke a physiological response. This helps the examiner gauge how the subject reacts to stress and establishes a baseline for the real test.
