Question

which physiological conditions do polygraph tests measure and record?
respiration, body temperature, heart rate, and blood pressure
heart rate, blood pressure, respiration, and skin conductivity
sweat levels, body temperature, heart rate, and blood pressure
sweat levels, body temperature, respiration, and skin conductivity

Explanation:

A polygraph measures physiological responses related to deception detection. The correct physiological conditions it measures are sweat levels (which relate to skin conductivity as sweat affects it), body temperature, respiration, and skin conductivity. Let's analyze each option:

• First option: Blood pressure is not a primary polygraph measure (polygraph focuses on more direct stress - related responses like sweat, respiration, skin conductivity, and sometimes temperature).
• Second option: Blood pressure is not a standard polygraph measure.
• Third option: Blood pressure is not a typical polygraph measurement; it focuses on sweat (related to skin conductivity), temperature, respiration, and skin conductivity.
• Fourth option: This option includes sweat levels (which impact skin conductivity), body temperature, respiration, and skin conductivity, all of which are physiological responses measured by a polygraph as they are associated with the body's stress response (which is linked to deception in polygraph theory).

Answer:

The fourth option (sweat levels, body temperature, respiration, and skin conductivity)
