Detailed explanation-1: -The accuracy (i.e., validity) of polygraph testing has long been controversial. An underlying problem is theoretical: There is no evidence that any pattern of physiological reactions is unique to deception. An honest person may be nervous when answering truthfully and a dishonest person may be non-anxious.
Detailed explanation-2: -What Is Polygraphy? The polygraph is commonly referred to as a lie detector, but it does not recognize lies. A specific physiological lie response has never been demonstrated and is unlikely to exist. Instead, it records physiological activity associated with arousal in the autonomic nervous system.
Detailed explanation-3: -A polygraph, often incorrectly referred to as a lie detector test, is a device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions.
Detailed explanation-4: -Which of the following describes the Yerkes-Dodson law? Simple tasks are performed best when arousal levels are relatively high, yet complex tasks are performed best when arousal level are low.
