CPE Psychophysiology 2

Question 1

The cardiovascular component of the polygraph most commonly records which parameter using a partially inflated blood pressure cuff?

Accepted Answer

Relative changes in blood pressure and pulse amplitude

Answer

Mean arterial pressure

Answer

Stroke volume

Answer

Cardiac output in liters per minute

Question 2

What is the primary physiological explanation for increased blood pressure observed in response to a deception-relevant stimulus during polygraph testing?

Accepted Answer

Sympathetic stimulation causing vasoconstriction and increased cardiac output

Answer

Increased parasympathetic tone causing vasodilation

Answer

Voluntary breath-holding raising intrathoracic pressure

Answer

Histamine release causing capillary expansion

Question 3

Which respiratory pattern change is most commonly associated with heightened sympathetic arousal during a polygraph examination?

Accepted Answer

Suppression of breathing or apnea followed by a deep breath

Answer

Increased tidal volume with slower rate

Answer

Regular slow diaphragmatic breathing

Answer

Cheyne-Stokes periodic breathing pattern

Question 4

In psychophysiology, the 'orienting response' to a novel stimulus is characterized by which combination of reactions?

Accepted Answer

Decreased heart rate, skin conductance increase, and attentional focus

Answer

Increased heart rate, pupil constriction, and muscle relaxation

Answer

Increased heart rate, skin conductance decrease, and pupil constriction

Answer

Decreased heart rate, vasoconstriction, and respiratory increase

Question 5

What does the term 'general arousal' refer to in the context of polygraph psychophysiology?

Accepted Answer

A non-specific elevation in physiological activity across multiple response channels

Answer

A subject's willingness to cooperate with the examiner

Answer

The maximum amplitude recorded on any single channel during the exam

Answer

The examiner's subjective rating of the subject's anxiety level

Question 6

Which glands are responsible for the electrodermal response measured in polygraph examinations, and where are they most densely located on the human body?

Accepted Answer

Eccrine sweat glands, most dense on the palms and soles

Answer

Apocrine glands, most dense on the scalp and axillae

Answer

Sebaceous glands, most dense on the face and chest

Answer

Merocrine glands, most dense on the upper back

Question 7

How does the concept of 'response specificity' apply to polygraph psychophysiology?

Accepted Answer

Individual subjects tend to show their largest responses consistently in one physiological channel

Answer

Each examiner elicits identical responses from all subjects

Answer

Each question type produces a response only in the cardiovascular channel

Answer

All physiological channels respond equally to every question stimulus
