CPE Examination Techniques 3

Question 1

What is the recommended minimum number of chart presentations in a standard polygraph examination to achieve a reliable numerical decision?

Accepted Answer

3

Answer

Most validated polygraph formats require at least three chart presentations to produce a reliable and defensible numerical decision.

Question 2

A sacrifice relevant question in polygraph testing serves which primary function?

Accepted Answer

To absorb initial orientation reactions and is not used for diagnostic scoring

Answer

The sacrifice relevant is placed early in the sequence to absorb the startle or novelty response, and its data are excluded from the diagnostic score.

Question 3

During a polygraph examination, an examinee exhibits a consistently larger cardio response to comparison questions than to relevant questions across all charts. This pattern most likely suggests:

Accepted Answer

Truthful behavior on the relevant issues

Answer

Greater reactivity to comparison questions relative to relevant questions is the expected pattern for a truthful examinee under validated comparison question techniques.

Question 4

The 'directed lie' comparison question (DLC) differs from the 'probable lie' comparison question (PLC) in that:

Accepted Answer

The DLC instructs the examinee to deliberately lie, while the PLC relies on assumed lies

Answer

In DLC, the examinee is explicitly instructed to answer falsely to a control question, creating a known lie; PLC relies on the assumption the examinee is lying about a broad past behavior.

Question 5

Which physiological component is primarily evaluated in the pneumograph tracing for deception-related responses?

Accepted Answer

Respiratory suppression, apnea, or changes in breathing pattern

Answer

The pneumograph measures respiratory activity, and deception-related responses typically appear as suppression, apnea, or irregular breathing patterns.
