CPE Data Analysis 2

Question 1

In the 7-position numerical scoring system, what score is assigned when the relevant question response is clearly stronger than the comparison question response?

Accepted Answer

+2

Answer

A +2 score indicates a clearly stronger response to the relevant question compared to the comparison question in the 7-position scoring system.

Question 2

Which physiological channel is most commonly associated with detecting suppression countermeasures during data analysis?

Accepted Answer

Electrodermal

Answer

The electrodermal (EDA) channel typically shows suppression artifacts most clearly, such as a flattened response pattern, when countermeasures are employed.

Question 3

What does a 'blocking' artifact in the respiration tracing indicate during polygraph data analysis?

Accepted Answer

A possible countermeasure or apnea

Answer

Blocking in respiration tracings — a sustained suppression of respiratory movement — is a classic indicator of possible countermeasure use or deliberate breath-holding.

Question 4

Under the Empirical Scoring System (ESS), what is the recommended minimum number of charts collected before making a conclusive determination?

Accepted Answer

2

Answer

ESS guidelines recommend collecting a minimum of 2 charts to allow reliable comparison of physiological responses across repeated question presentations.

Question 5

During global analysis, an examiner evaluates the overall pattern of responses. Which of the following best describes a 'significant response' in global scoring?

Accepted Answer

A consistent and prominent physiological reaction across multiple channels

Answer

Global analysis identifies significant responses as those that are consistent, prominent, and appear across multiple physiological channels rather than isolated single-channel deviations.
