MASTERING BODY LANGUAGE

Interrogators must be able to use their own nonverbals correctly. Facial expressions may convey an attitude of sincerity, shock, surprise, humor, sorrow, or concern. Meaningful communication is also dependent upon the tone of voice, inflections in delivery, emphasis on words, the use of guttural sounds, body space, body movement and gestures, proper use of time, control of profanity and slang, appropriate physical appearance, and studied use of attire.

When interviewees lie, a myriad of biological and physiological processes taking place in their minds and bodies can be recognized by skilled interrogators.

​The indicators of lying include perspiration flow; flushing or paleness of the skin; pulse rate increase or decrease which is apparent from the appearance of visible veins in the head, neck, and throat; dry mouth and tongue; excessive swallowing; respiratory changes; muscle spasms; licking of the lips; thickened and slurred speech; stuttering; darting eye movements; rigidity of the body; the 'playing' of the hands with each other; clenched fists; and cold, clammy sweat in the palms of the hands.

Nonverbals appear most prominently in the face, and facial tics often indicate lying. Many subjects who are on the verge of confessing will pick their fingernails, scratch themselves, dust their clothing, or fumble with small objects. Interrogators should politely terminate such conduct so that telling the truth remains as the suspects' only channel of tension relief. However, all persons do not exhibit the same nonverbals under similar circumstances.

​For example, a flushing or blushing face on an easily embarrassed person does not necessarily mean that the person is concealing the truth. Furthermore, mentally disturbed persons often exhibit signs of their illness which are similar to indicators of lying. Interrogators must alter their own nonverbal tactics when they deal with such persons; they should not use the 'hot and cold' method, bluffing, or emotional approaches with the mentally ill to avoid receiving false confessions.

POSITIVE BODY LANGUAGE

During an interview, your body language can speak just as loudly as your words. Here are some positive body language techniques to keep in mind:

Posture
Sitting up straight with your shoulders back conveys confidence and professionalism. Slouching or hunching over can make you appear disinterested or unprofessional. Leaning forward slightly can show that you are engaged in the conversation and interested in what the interviewer(s) is saying.

Eye Contact
Making eye contact with the interviewer(s) shows that you are confident, engaged, and interested in the conversation. Maintaining eye contact can help establish a connection and build rapport. However, be careful not to stare too intensely or for too long, as this can be perceived as aggressive or uncomfortable.

Facial Expressions
Smiling can help make you appear friendly, approachable, and enthusiastic. Nodding your head and making other positive facial expressions can show that you are listening and engaged. However, be careful not to overdo it or appear insincere.

Hand Gestures
Using hand gestures can help emphasize points and convey enthusiasm. However, be careful not to overdo it or make wild, distracting movements. Using natural, subtle hand movements can help make you appear more engaging and confident.

Tone of Voice
Speaking clearly and with conviction can help make you appear more confident and professional. Varying your tone and pitch can help make you appear more engaging and interesting. Avoid speaking too quietly or too quickly, as this can make you appear nervous or unsure of yourself.

NEGATIVE BODY LANGUAGE

In addition to positive body language techniques, it’s important to be aware of negative body language that can detract from your interview performance. Here are some things to avoid:

Avoiding Eye Contact
Makes you appear untrustworthy, disinterested, or nervous. If you’re feeling uncomfortable making direct eye contact, try looking at the interviewer’s forehead or chin instead.

Slouching or Leaning Back
Can make you appear disinterested or disrespectful. Sitting up straight with your shoulders back can help convey confidence and professionalism.

Crossing Arms or Legs
Might make you appear closed off or defensive. Keeping your arms and legs uncrossed can help you appear more open and approachable.

Fidgeting or Playing with Hair/Jewelry
Could be distracting and convey nervousness. Try to keep your hands still and your body relaxed.

Speaking too Quickly or Softly
Can make it difficult for interviewers to understand you or follow your thoughts. Speaking too softly can make you appear unsure of yourself or lacking in confidence. Speak at a moderate pace and volume to make yourself clear and easy to understand.
