CPE CPE Countermeasure Detection 2

Question 1

Which of the following behaviors during a polygraph examination should alert an examiner to potential countermeasure use?

Accepted Answer

Visible muscle tension in the lower body timed with control questions

Answer

Visible lower-body muscle tension—such as pressing toes down or flexing leg muscles—timed specifically with control questions is a classic indicator of physical countermeasure use.

Question 2

How does a trained polygraph examiner typically address suspected countermeasure use during an ongoing examination?

Accepted Answer

Administer additional chart runs and address the behavior in post-test

Answer

Examiners typically continue collecting data, administer additional chart runs, and then address suspected countermeasure activity during the post-test phase to preserve examination validity.

Question 3

What role does the activity sensor (seat pad or floor mat) play in countermeasure detection?

Accepted Answer

It detects physical movements that may indicate countermeasure attempts

Answer

An activity or motion sensor records physical movements by the subject, allowing examiners to correlate muscle activity with specific questions and identify potential physical countermeasures.

Question 4

Which type of countermeasure involves using pharmacological substances (e.g., tranquilizers or stimulants) to alter polygraph outcomes?

Accepted Answer

Chemical countermeasures

Answer

Chemical countermeasures involve using drugs—such as anti-anxiety medications, beta-blockers, or other substances—to dampen or alter physiological responses during a polygraph examination.

Question 5

What is the primary purpose of the 'eyes-open/eyes-closed' or 'sit quietly' instruction given before chart collection?

Accepted Answer

To establish a stable physiological baseline and reduce spontaneous movement

Answer

Requiring the subject to sit quietly before each chart establishes a stable baseline, making it easier to detect deviations caused by relevant questions or countermeasure activity.
