CPE Data Analysis 3

Question 1

In Backster's scoring system, a score of '-1' on a relevant question indicates:

Accepted Answer

A slight response favoring the relevant question

Answer

In Backster's system, a -1 score means the relevant question produced a slightly stronger physiological reaction compared to the comparison, suggesting a mild deception-consistent response.

Question 2

Which analysis method requires a blind examiner to score charts without knowledge of the case facts or prior analysis results?

Accepted Answer

Blind chart analysis

Answer

Blind chart analysis requires the scoring examiner to have no knowledge of case facts, prior opinions, or context to eliminate confirmation bias.

Question 3

When analyzing electrodermal activity (EDA), what response feature is most significant for scoring comparison versus relevant question reactions?

Accepted Answer

Amplitude and duration of response onset relative to question stimulus

Answer

Examiners score EDA by evaluating the amplitude and onset timing of responses to each question stimulus, comparing the relative magnitude between comparison and relevant questions.

Question 4

During spot analysis, a polygraph examiner compares the physiological response to a relevant question against:

Accepted Answer

The response to the immediately adjacent comparison question

Answer

Spot analysis evaluates each relevant question's response against the comparison question that is structurally adjacent to it in the test format.

Question 5

What is the primary purpose of calculating 'Total Chart Minutes' (TCM) in polygraph data analysis?

Accepted Answer

To quantify the amount of physiological data available for scoring

Answer

TCM quantifies the total usable physiological recording time across all charts, providing an estimate of data sufficiency for reliable analysis.
