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) a blood pressure biofeedback device
B) a plethysmograph
C) a gauge of pupillary response
D) a polygraph

Question

Quizplus · Accepted Answer

The procedure described in the question, which involves obtaining a written record of multiple physiological changes in response to an interview, is typically associated with the use of a polygraph. A polygraph (commonly known as a lie detector) measures several physiological indicators of stress or arousal, such as heart rate, blood pressure, and respiration, while a person is asked a series of questions. The resulting chart of these physiological changes is then used to determine whether the person is being truthful or deceptive in their responses. The other instruments listed (blood pressure biofeedback device, plethysmograph, gauge of pupillary response) may measure physiological changes as well, but are not typically associated with the specific type of procedure described in the question.
