  1. In the 7-position numerical scoring system, what score is assigned when the relevant question response is clearly stronger than the comparison question response?

    Answer: +2

    A +2 score indicates a clearly stronger response to the relevant question compared to the comparison question in the 7-position scoring system.

  2. Which physiological channel is most commonly associated with detecting suppression countermeasures during data analysis?

    Answer: Electrodermal

    The electrodermal (EDA) channel typically shows suppression artifacts most clearly, such as a flattened response pattern, when countermeasures are employed.

  3. What does a 'blocking' artifact in the respiration tracing indicate during polygraph data analysis?

    Answer: A possible countermeasure or apnea

    Blocking in respiration tracings — a sustained suppression of respiratory movement — is a classic indicator of possible countermeasure use or deliberate breath-holding.

  4. Under the Empirical Scoring System (ESS), what is the recommended minimum number of charts collected before making a conclusive determination?

    Answer: 2

    ESS guidelines recommend collecting a minimum of 2 charts to allow reliable comparison of physiological responses across repeated question presentations.

  5. During global analysis, an examiner evaluates the overall pattern of responses. Which of the following best describes a 'significant response' in global scoring?

    Answer: A consistent and prominent physiological reaction across multiple channels

    Global analysis identifies significant responses as those that are consistent, prominent, and appear across multiple physiological channels rather than isolated single-channel deviations.

  6. In the Utah Zone Comparison Technique (UZCT), which component is evaluated first during the data analysis phase?

    Answer: Respiratory line quality and artifacts

    UZCT data analysis typically begins with a review of respiratory tracings for quality and artifacts before scoring comparative responses.

  7. What statistical metric is used to quantify the trade-off between sensitivity and specificity in polygraph diagnostic accuracy studies?

    Answer: Area Under the ROC Curve (AUC)

    The Area Under the ROC Curve (AUC) summarizes a test's diagnostic accuracy by capturing the balance between true positive rate (sensitivity) and false positive rate across decision thresholds.
