One Study Examined Whether Subjects Could Accurately Identify Who Was

One study examined whether subjects could accurately identify who was telling the truth and who was telling a lie. The results indicated that people with left-hemisphere damage were more accurate than a group of college students. How could people with left-hemisphere damage be more accurate?

A) They could not understand what was being said, so they relied on gestures and facial expressions.
B) They could not understand the emotional content, so they focused more attention on precisely what was being said.
C) The deception detectors are located in the right hemisphere, and these were not damaged.
D) For reasons that are not clear, people with left-hemisphere damage guess better than chance on many different types of tasks.
