An individual's _______ brain waves are measured in brain fingerprinting.

Directions: Read the paragraph and answer the question that follows:

Brain fingerprinting is a technique which is designed to determine whether an individual recognizes specific information related to an event or activity by measuring electrical brain waves. The technique works only in situations where investigators have a sufficient amount of specific information about an event or activity that could only have been known to the investigator and criminal.

Brain fingerprinting measures electrical brain activity via a fitted headband containing special sensors. In this, the person who has to be tested wears a headband with electronic sensors that measure the brain waves from several locations on the scalp. Brain fingerprinting uses cognitive brain responses and it does not depend upon the emotions of a subject.

Dr. Lawrence Farwell is the inventor of the technique who has used the technique in one court case to determine the innocence of a man convicted of a murder. In his experiment, Farwell showed each person pictures from the crime scene and measured their brainwave response to see which person had seen the crime scene before. Farwell claimed the test is 99.99 infallible and he convinced the court to free the convicted person. The technique can be used to fight terrorism if mandated. On the other hand, critics question whether brain fingerprinting could be administered efficiently and without a considerable number of false readings.
