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

    Answer: 3

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

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

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

    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.

  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:

    Answer: Truthful behavior on the relevant issues

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

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

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

    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.

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

    Answer: Respiratory suppression, apnea, or changes in breathing pattern

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

  6. In the Air Force Modified General Question Test (AFGQT), how many relevant questions are typically included per chart?

    Answer: 3

    The AFGQT typically includes three relevant questions per chart, focusing the examination on the specific issues under investigation.

  7. An examinee who deliberately hyperventilates before a relevant question is most likely attempting to:

    Answer: Suppress autonomic responses to the relevant question by altering blood CO2 levels

    Hyperventilation lowers blood CO2, which can blunt autonomic responses and is a known countermeasure used to suppress reactions to relevant questions.
