An approach to lie detection that assesses a suspect's physiological response to details of a crime known only to police investigators is called the

A) polygraph.
B) two-factor therapy.
C) Physiological Assessment Test.
D) Concealed Information Test.

The approach described in the question is known as the Concealed Information Test, which assesses a suspect's physiological response (such as changes in heart rate and sweat production) to details of a crime known only to investigators, in order to determine if the suspect has knowledge of those details and may be involved in the crime. The polygraph is a more commonly known lie detection tool that measures physiological responses to a series of questions, whereas the other two options (two-factor therapy and Physiological Assessment Test) are not related to the specific approach described in the question.
