Document Summary
_________________________________________________________________________: polygraph: a device for recording an individual"s autonomic nervous system responses. This type of deception detection relies on an underlying assumption that deception is associated with certain physiological changes, such as an increased blood pressure, heavy breathing, increased heartbeat, and galvanic skin responses. Application of the polygraph test: polygraphs are used most commonly in criminal investigations when a police officer may ask a suspect to take a polygraph test. If the suspect fails the test, they may be pressured to confess, thereby giving the police incriminating evidence. Polygraph test results are not admissible in court, so they are only used to detect deception and aid the decision to proceed with an interrogation: polygraphs are also used ask alleged victims if a crime actually occurred. Types of polygraph tests: polygraphs rely on measuring physiological responses to different types of questions.
