Final answer:
The Guilty Knowledge Test is a polygraph test used to determine if a person has specific knowledge about a crime.
Step-by-step explanation:
The Guilty Knowledge Test is a specific type of polygraph test used in criminal investigations to determine if a person has specific knowledge about a crime. This test is based on the theory that a guilty person will have knowledge about the crime that an innocent person would not have. During the test, the investigator presents multiple-choice questions that only someone with knowledge of the crime would be able to answer correctly. The person's physiological responses, such as heart rate and sweat level, are measured to detect signs of arousal when they are confronted with correct answers related to the crime.
