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?
Giselle will use several techniques to determine whether her suspect's responses are deceptive or not, including:
1. Monitoring physiological responses: Giselle will monitor the suspect's physiological responses such as changes in heart rate, blood pressure, respiration rate, and sweat gland activity. If the suspect's physiological responses indicate deception, it is likely that they are lying.
2. Analyzing the suspect's verbal and nonverbal cues: Giselle will analyze the suspect's verbal and nonverbal cues such as body language, facial expressions, tone of voice, and speech patterns. If the suspect shows signs of nervousness, hesitation, or inconsistency in their responses, it could indicate deception.
3. Asking follow-up questions: Giselle will ask follow-up questions to clarify any inconsistent or suspicious responses from the suspect. Inconsistent or suspicious responses may indicate deception.
4. Comparing the suspect's responses to the baseline: Giselle will compare the suspect's responses during the actual crime questions to their responses during the baseline questions. If there are significant differences in the suspect's physiological responses or demeanor, it could indicate deception.
By using these techniques, Giselle can determine whether her suspect's responses are deceptive or not during the polygraph examination.
