Detecting High Stress in Oral Interviews and Text Documents

When a person is interviewed, some of the answers may be inaccurate, or even deceptive, because the person may have either incomplete information, is telling only part of the truth, or is fabricating a false answer, or a combination of all three. When the person is habitually making statements that are known to be false, or only partly true, emotional and/or intellectual conflicts often arise within them, and these conflicts may become manifest by inconsistencies in use of different parts of speech or in logical relationships between statements. These inconsistencies are more subtle than inconsistencies in factual statements, and identification of these inconsistencies is more difficult and less straightforward than identification of factual inconsistencies.
