Introduction
The Kentucky Polygraph Examiner Licensing Examination is designed to evaluate the professional
competence and foundational readiness of candidates seeking licensure within the Commonwealth. This
comprehensive assessment measures critical skills and knowledge related to psychophysiological
detection of deception, standard testing methodologies, chart interpretation, and adherence to state legal
statutes. Featuring a rigorous blend of multiple-choice and scenario-based items, the evaluation places
significant emphasis on real-world application, operational ethics, and sound decision-making under
complex investigative conditions. Candidates must demonstrate proficiency across physiological
monitoring principles, interview dynamics, and statutory compliance required for ethical practice.
Which autonomic nervous system branch is primarily responsible for the sympathetic activation
observed during a deceptive response on a polygraph chart?
,A. Parasympathetic nervous system
B. Enteric nervous system
C. Sympathetic nervous system
D. Somatic nervous system
🟢 C. Sympathetic nervous system
🔴 RATIONALE: The sympathetic nervous system mediates the fight-or-flight response, producing
physiological changes such as increased electrodermal activity and cardiovascular variation
associated with perceived threat during deception.
What is the primary physiological basis for recording electrodermal activity (EDA) during a
polygraph examination?
A. Changes in skeletal muscle tension
B. Variations in peripheral blood volume
C. Changes in the electrical resistance of the skin due to sweat gland activity
D. Fluctuations in arterial blood pressure
🟢 C. Changes in the electrical resistance of the skin due to sweat gland activity
🔴 RATIONALE: Electrodermal activity measures sweat gland output, which alters skin resistance
or conductance under sympathetic nervous system arousal.
In a standard control question test (CQT), what is the primary purpose of a control question?
A. To calibrate the baseline physiological stability of the examinee
B. To elicit a known or probable deceptive response from a non-deceptive examinee for
comparison
C. To measure the absolute physiological ceiling of the subject
D. To verify the operational calibration of the pneumograph components
🟢 B. To elicit a known or probable deceptive response from a non-deceptive examinee for
comparison
,🔴 RATIONALE: Control questions are structured to cause concern in innocent examinees,
allowing comparison with relevant questions concerning the primary issue.
Under Kentucky administrative regulations governing polygraph examiners, how long must an
examiner maintain complete records of an examination?
A. One year
B. Two years
C. Three years from the date of the examination
D. Five years
🟢 B. Two years
🔴 RATIONALE: Kentucky administrative standards typically mandate that all examination
recordings, charts, and notes be retained for a minimum of two years by the licensed examiner.
Which physiological parameter is monitored by the pneumograph component during a polygraph
test?
A. Peripheral pulse amplitude
B. Relative changes in thoracic and abdominal respiration
C. Blood volume pulse changes
D. Micro-volts of skin potential
🟢 B. Relative changes in thoracic and abdominal respiration
🔴 RATIONALE: Pneumograph chest assemblies record breathing patterns, tracking changes in
inspiration and expiration cycles across questioning.
What term describes the phenomenon where an examinee attempts to distort physiological
tracings by intentionally altering breathing or tensing muscles?
A. Habituation
B. Countermeasure
C. Sensitization
, D. Accommodation
🟢 B. Countermeasure
🔴 RATIONALE: Countermeasures are deliberate physical or mental manipulations performed by
an examinee to distort baseline readings and affect test outcome.
Which questioning technique utilizes Directed Lie Control (DLC) questions rather than traditional
formulated control questions?
A. Reid Technique
B. Zone Comparison Test
C. Federal Trilogy (DLCT)
D. Backster Zone Comparison
🟢 C. Federal Trilogy (DLCT)
🔴 RATIONALE: Directed Lie Control tests instruct the examinee to intentionally lie to a specific,
non-case control question during the pre-test phase.
When conducting a pre-test interview, what is the primary objective of reviewing all test questions
word-for-word with the examinee?
A. To intimidate the examinee into a confession
B. To ensure the examinee has no semantic misunderstandings or ambiguities regarding the
questions
C. To establish the legal binding nature of the interview
D. To calibrate the pneumograph baseline
🟢 B. To ensure the examinee has no semantic misunderstandings or ambiguities regarding the
questions
🔴 RATIONALE: Reviewing questions eliminates surprise, ensuring any physiological response is
due to psychological significance rather than confusion over wording.
