1. Which physiological systems are primarily measured in a standard
polygraph examination?
A. Respiratory, cardiovascular, and electrodermal activity
B. Muscular, skeletal, and digestive systems
C. Endocrine, lymphatic, and nervous systems
D. Auditory, visual, and olfactory systems
Answer: A
The standard polygraph records respiration, heart rate/blood
pressure, and skin conductance because these involuntary responses
are associated with emotional arousal and deception.
2. The purpose of the pre-test interview is to:
A. Accuse the examinee of deception
B. Establish rapport and review test questions
C. Begin physiological recording immediately
D. Deliver the final results
Answer: B
The pre-test interview clarifies procedures, ensures understanding,
and helps develop relevant test questions while building cooperation.
3. Which chart component reflects changes in sweat gland activity?
A. Pneumograph
B. Cardiograph
C. Electrodermal activity (EDA) channel
, D. Stethoscope recording
Answer: C
The electrodermal activity channel measures skin conductivity, which
increases with sympathetic nervous system activation.
4. Relevant questions should be:
A. Emotionally neutral
B. Related directly to the issue under investigation
C. About personal history only
D. Trick questions
Answer: B
Relevant questions address the specific allegation being tested to
elicit diagnostic physiological responses.
5. The comparison question technique is designed to:
A. Confuse the examinee
B. Provide a baseline for evaluating responses
C. Replace relevant questions
D. Eliminate all stress
Answer: B
Comparison questions help establish physiological baselines for
interpreting reactions to relevant questions.
6. Countermeasures during a polygraph test refer to:
A. Approved breathing techniques
B. Attempts to distort test results
C. Examiner training methods
D. Equipment calibration steps
Answer: B
Countermeasures are deliberate attempts to manipulate
physiological responses to affect test outcomes.
7. Which factor can affect polygraph results?
A. Proper room lighting
B. Examinee anxiety
C. Examiner attire
D. Paper color
Answer: B
, Emotional states such as anxiety can influence physiological
responses and must be considered during interpretation.
8. The cardiovascular channel measures:
A. Brain waves
B. Blood pressure and pulse
C. Muscle tension
D. Skin temperature
Answer: B
The cardiovascular component tracks heart rate and blood pressure
changes associated with arousal.
9. Question sequencing is important because it:
A. Reduces equipment cost
B. Influences physiological response patterns
C. Eliminates the need for training
D. Replaces analysis
Answer: B
Proper sequencing ensures valid comparisons between relevant and
comparison questions.
10. A polygraph examiner must maintain:
A. Personal opinions
B. Neutral and objective behavior
C. Aggressive questioning style
D. Legal authority
Answer: B
Professional neutrality prevents bias and preserves the integrity of
the examination.
11. The primary goal of a polygraph examination is to:
A. Provide absolute proof
B. Assist in truth verification
C. Replace investigations
D. Secure confessions
Answer: B
Polygraph testing assists decision-making but does not provide
absolute proof.
