The procedure whereby a written record of multiple physiological changes is obtained in response to a specially devised interview is BEST associated with which of the following instruments?
A) biofeedback instruments
B) a plethysmograph
C) a gauge of pupillary response
D) a polygraph

Question

Quizplus · Accepted Answer

The procedure described in the question refers to a polygraph. A polygraph is an instrument that measures multiple physiological changes such as breathing, blood pressure, and skin conductivity in response to questioning. It is often used in law enforcement and investigative situations to detect deception. Biofeedback instruments are used to monitor and manage physiological responses such as muscle tension and heart rate, but typically do not involve an interview process. A plethysmograph measures changes in blood volume, usually in a specific body part, while a gauge of pupillary response measures changes in the size of the pupils in response to light or other stimuli.
