CVSA Physiological Basis of Voice Stress Analysis 2

Question 1

According to the theoretical basis of CVSA, what happens to vocal microtremors when a person experiences psychological stress?

Accepted Answer

They are suppressed or diminished

Answer

They remain completely unchanged

Answer

They increase in frequency

Answer

They shift to a higher pitch range

Question 2

The medical concept of 'muscle tension dysphonia' is relevant to CVSA because it:

Accepted Answer

Demonstrates how stress-related muscle tension can alter voice quality

Answer

Is a condition that CVSA can clinically diagnose

Answer

Describes the acoustic output produced during a CVSA examination

Answer

Is the legal standard for admissibility of CVSA evidence in court

Question 3

The 'cognitive load' theory is relevant to CVSA because it proposes that:

Accepted Answer

Deception requires additional mental processing that generates detectable stress

Answer

CVSA only produces valid results with highly intelligent subjects

Answer

Subjects must be given arithmetic problems to elevate their cognitive state

Answer

Only numerical questions produce accurate stress readings

Question 4

Cortisol, a primary stress hormone, is relevant to CVSA readings because it:

Accepted Answer

Contributes to the physiological stress response that elevates muscle tension

Answer

Directly disrupts the CVSA software's signal-processing algorithms

Answer

Only affects the voice patterns of female subjects

Answer

Causes subjects to involuntarily switch languages under stress

Question 5

Understanding the physiological basis of CVSA technology is important for operators primarily because it:

Accepted Answer

Helps them properly interpret results and account for individual physiological variation

Answer

Enables them to perform medical examinations on subjects before testing

Answer

Allows them to repair the CVSA hardware when it malfunctions

Answer

Qualifies them to prescribe anxiety-reducing medications

Question 6

The 'baseline' measurement phase in a CVSA examination is critical because it:

Accepted Answer

Establishes the individual's normal physiological voice patterns for comparison

Answer

Measures the subject's blood pressure before testing begins

Answer

Sets the recording equipment's volume level for the session

Answer

Determines whether the subject is medically fit to undergo testing

Question 7

Which condition would most significantly compromise the physiological validity of a CVSA examination?

Accepted Answer

The subject taking medications that suppress the autonomic stress response

Answer

The subject being left-handed

Answer

The examination room being slightly warmer than average

Answer

The subject speaking English with a slight foreign accent
