CPE CPE Countermeasure Detection

Question 1

Which of the following is classified as a physical countermeasure during a polygraph examination?

Accepted Answer

Pressing the toes against the floor during control questions

Answer

Physical countermeasures involve deliberate muscle movements or physical actions—such as pressing the toes down or biting the tongue—to artificially augment physiological responses to control questions.

Question 2

What term describes a subject's attempt to reduce physiological responses to relevant questions through mental strategies?

Accepted Answer

Mental countermeasures

Answer

Mental countermeasures involve cognitive strategies such as counting, performing mental arithmetic, or visualizing calming scenes to suppress arousal to relevant questions.

Question 3

Which channel of the polygraph is considered most resistant to voluntary physical countermeasures?

Accepted Answer

Cardio (blood pressure/pulse)

Answer

The cardiovascular channel is generally considered harder to voluntarily manipulate compared to respiration, as most subjects cannot consciously control heart rate and blood pressure changes.

Question 4

What does the term 'augmentation' refer to in the context of polygraph countermeasures?

Accepted Answer

Artificially inflating physiological responses to non-relevant questions

Answer

Augmentation countermeasures involve deliberately enhancing physiological responses to control or comparison questions to make them appear larger than responses to relevant questions.

Question 5

Which physiological indicator in the respiratory tracing is most commonly associated with countermeasure use?

Accepted Answer

Irregular baseline with apnea periods near relevant questions

Answer

Deliberate breath-holding (apnea) or irregular breathing patterns near relevant questions are hallmark signs of respiratory countermeasure attempts.
