Question

possible points: 4
giselle is a polygraph examiner in the middle of an interview with a suspect. she has established her baseline and is now asking questions that pertain to the actual crime. how will giselle determine whether her suspect’s responsive are deceptive or not?
she will trust her instincts to guide her.
she will expect the suspect to be truthful since they know they will be found out quickly if they lie.
she will compare the baseline data with the new data recorded.
she will use the baseline as needed but will primarily rely on body language cues to guide her.

Explanation:

In polygraph examination, the standard procedure involves establishing a baseline of the subject's physiological responses (like heart rate, respiration, etc.) and then comparing new data (during questioning about the crime) to this baseline to detect deception. Trusting instincts (first option) is not scientific. Expecting truthfulness (second) ignores the need to verify. Relying on body language (fourth) is not the primary polygraph method. Comparing baseline and new data is the correct approach.

Answer:

C. She will compare the baseline data with the new data recorded.
