Officers and lie detection: Take the body language quiz
Humans use many forms of deception. Facial expression is a very complex and easily manipulated form of communication. Facial expression can be quite subtle. Few individuals are accomplished in correctly interpreting deceptive motives or emotions. To complicate matters, facial expression is achieved using infinite combination of musculature, features, skin plasticity and complexion. Even the skilled Secret Service Agent can be misled.
Body language test: Understanding body language
Understanding body language is critical for officer safety. There is more to body language than movement. Behavioral studies indicate that individuals establish a personal space circumference, which may change depending on the type of message they are sending and their goal.
We establish a comfortable distance for personal interaction and nonverbal (unconsciously) define this as our perimeter. Personal distance is just as much a part of non-verbal communication as a smile or a snarl. By the way, notice if a smile uses all of the face muscles or just a few around the mouth. More muscles equal a more natural, unforced smile.
If one is distrustful (e.g., paranoia), his or her space will probably be larger. From basic training law enforcement officers are taught to keep a safe distance from suspects. If we perceive danger or dislike, even if we are not consciously aware of that perception, we will probably increase our protected space. If you find yourself moving back from a suspect you have probably picked up a danger signal at a subconscious level. Pay attention!
Consider this: If a suspect moves into your personal space it may well be a sign of aggression or implied intimidation. There are four parts to tactical body language: facial expression, gestures, stance and personal space. Unfortunately, it is a two-way street — while you are watching a suspect’s body language, he or she is simultaneously watching yours. Study your body language in a mirror. What messages do you send? You might be surprised.
Here are a few obvious facial signals: 1) nostril flare (arousal, anger). 2) grin (happiness, affiliation, contentment); grimace (fear); lip compression (anger, high emotion, frustration);canine snarl (disgust); lip pout (sadness, submission, uncertainty, seduction). Sneer (contempt, intimidation. 3) Frown (anger, sadness, concentration); brow raise (intensity, curious, slight surprise). 4) Big pupils (arousal, fight-or-flight, drugs). Small pupils (rest-and-digest,); direct gaze (affiliate, threaten, deception); gaze-down (submission, deception, distraction). (Adapted from Givens, 1998-202, Center for Nonverbal Studies.)
Remember, you are not the only person who studies body language. Misleading body language can be used to do just that — mislead. Look at the individual’s entire presentation when in doubt. Incongruity may be an attempt to conceal or mislead. As a Dallas cop told me, the truth is consistent. When the spoken word is at cross purposes with body language, normally it is safer to believe the body because body language is more likely to be unconscious.

13. If a suspect uses a contraction, such as "I didn’t do it," in answer to your question, “Did you kill your aunt?” he is more likely to be telling the truth than if he were to say, “No, I did not.” Contractions seem to be more trustworthy.
|When Nevada Highway Patrolman Eddie Dutchover pulled over a wanted polygamist, Warren Steed Jeffs, in August 2006, the officer noticed a furiously pumping carotid artery in Jeff’s neck. This clue was the cash pot: Jeffs was on the FBI’s 10 Most Wanted Fugitives List. Read story.|
Scoring your test:
Give yourself one point for every correct answer. You can give yourself more points, but it will make scoring confusing.
What does my score mean?
Score 1 – 4
I am afraid that you might find surviving on the mean streets more challenging than other officers. You are more likely to miss a body language signal that precedes an aggressive act. Also, you are more likely to misjudge a suspect’s intention and truthfulness. You may want to learn more about body language by visiting the Non-Verbal Communication Web site; it is quite interesting. To be safe, stay close to someone who scored 10 or more on the test.
Score 5 – 8
You are doing relatively well and can probably communicate and understand body language communication with little effort. You may want to visit the reference site listed above to increase your store of knowledge. What does it mean when someone looks up and to the right while taking your picture with his/her cell phone? See, I told you there was more to learn.
Score 9 – 13
You should be working for the Secret Service. You are unusually knowledgeable about body language. This knowledge will give you a distinct advantage in understanding your fellow creatures. Let me warn you, some of the nice officers from the first scoring group are going to be looking for you.
Would you like to know how to consistently identify dishonesty? According to body language expert Robert Phipps, “Darting eyes, palms not visible, shifting from one foot to another, hand covering mouth or finger tugging at the ear are clues.” Regrettably, as you know these indicators are not always accurate. You should keep researching and learning about body language and lie detection. The more you know the safer you are, and in law enforcement that is your prime directive, stay safe.
I suggest that you read Frogs into Princes: Neuro Linguistic Programming. Richard Bandler and John Grinder. I read it several years ago and through it is not an easy read it contains some fascinating information for understanding yourself and others. Also the site listed under the first scoring category above is a treasure trove of useful information. Begin your own research study. Watch your fellow beings and make note of their behavior under various circumstances.
