Investigators will better understand what these signals may mean and how to use the information during investigative interviews and criminal interrogations. Research has shown that there are seven universal expressions of emotion occurring during true/felt emotions which the astute investigator may be able to identify during interviews or interrogations. When people lie it is often accompanied with changes in their expressions of emotion through simulating (expressing an un-felt emotion), masking (replacing a felt emotion with a false expression), or neutralizing (inhibiting a true emotion by appearing neutral). The exhibited emotions and micro expressions are often subconscious and difficult for people to hide, but when identified through training, this added knowledge gained by the investigator is able to provide additional insight to help focus questioning and to assist with assessing the credibility of what the individual is saying, and to identify any conflicts or mixed messages in what the individual is conveying.
