CPE Data Analysis 4

Question 1

In cardiovascular analysis, what tracing feature is most often associated with a significant response to a test question?

Accepted Answer

Rise in relative blood pressure and changes in pulse amplitude

Answer

Decrease in pulse rate only

Answer

Sustained hypertension throughout the chart

Answer

Stable diastolic baseline with minor fluctuations

Question 2

Which scoring approach assigns different weights to physiological channels based on their empirical validity in detecting deception?

Accepted Answer

Empirical Scoring System (ESS)

Answer

Backster's 3-position system

Answer

Global subjective scoring

Answer

Predictive Table Analysis

Question 3

A 'persistent augmented response' on a relevant question across multiple chart presentations is most consistent with which scoring interpretation?

Accepted Answer

Strong deceptive indication

Answer

Inconclusive due to habituation

Answer

Probable truthful response

Answer

Countermeasure artifact

Question 4

What is the significance of 'habituation' when analyzing polygraph data across multiple chart runs?

Accepted Answer

It may diminish comparison question responses, reducing their diagnostic utility

Answer

It increases the accuracy of relevant question responses over time

Answer

It eliminates the need for a control or comparison question

Answer

It has no effect on data interpretation guidelines

Question 5

During data analysis, which respiratory feature is considered a valid response indicative of a significant reaction rather than an artifact?

Accepted Answer

A suppression of respiratory amplitude onset immediately after the relevant question

Answer

A mid-question cough causing a spike

Answer

A deep breath taken during the inter-question interval

Answer

A spontaneous sigh prior to the first relevant question

Question 6

When a polygraph examiner notes a 'staircasing' pattern in the cardiograph tracing, what does this most likely indicate?

Accepted Answer

Increasing blood pressure across multiple consecutive relevant questions

Answer

Normal respiration-linked oscillation

Answer

Instrument malfunction in the blood pressure cuff

Answer

Examinee falling asleep

Question 7

In the Predictive Table Analysis (PTA) approach, decisions are based primarily on:

Accepted Answer

Statistically derived probability tables correlating score totals to accuracy rates

Answer

Examiner's subjective impression of the examinee's demeanor

Answer

The number of charts collected only

Answer

A single-channel dominant scoring rule
