1. What is the primary purpose of a polygraph examination?
A. To detect lies with 100% certainty
B. To measure physiological responses associated with
deception
C. To replace criminal investigations
D. To provide legal verdicts
Rationale: Polygraphy measures physiological responses, not
absolute truth.
Correct answer: B
2. Which system is most directly monitored in a polygraph
test?
A. Digestive system
B. Cardiovascular system
C. Muscular system only
D. Skeletal system
Rationale: Polygraph measures autonomic responses including
heart rate.
Correct answer: B
3. The galvanic skin response measures:
A. Brain waves
B. Sweat gland activity
,C. Blood sugar levels
D. Lung capacity
Rationale: It measures electrical conductance of skin due to
sweat.
Correct answer: B
4. Polygraph testing is based primarily on:
A. Behavioral observation
B. Psychological stress responses
C. Fingerprinting
D. DNA analysis
Rationale: It relies on physiological changes from psychological
stress.
Correct answer: B
5. The pneumograph measures:
A. Blood pressure
B. Respiration
C. Eye movement
D. Temperature
Rationale: It records breathing patterns.
Correct answer: B
6. A polygraph examiner must primarily avoid:
A. Documentation
B. Bias
C. Equipment calibration
D. Interviewing
, Rationale: Bias affects validity of results.
Correct answer: B
7. The control question technique is used to:
A. Confuse the subject
B. Compare responses to relevant questions
C. Avoid questioning
D. Diagnose medical conditions

Correct answer: B
8. A baseline physiological response is:
A. Maximum stress response
B. Normal resting response
C. Drug-induced response
D. Emotional peak response
Rationale: Baseline is normal unstressed state.
Correct answer: B
9. Polygraph charts primarily record:
A. DNA data
B. Physiological tracings
C. Written statements
D. Audio recordings
Rationale: Charts show physiological signals over time.
Correct answer: B
10. Deception is inferred from:
