Nonverbal Communication

The Silent Language

Mehrabian's famous 55/38/7 split (body language, tone, words) is often cited but applies narrowly to messages about feelings and attitudes, and has been widely misapplied. Still, nonverbal cues carry real weight in how you come across, especially when what you're saying conflicts with how you're saying it.

What is Nonverbal Communication?

Everything you communicate without words:

• Body language: Posture, gestures, movements
• Facial expressions: Emotions shown on your face
• Eye contact: Where and how you look
• Proxemics: Personal space and distance
• Touch: Handshakes, pats, hugs
• Appearance: Clothing, grooming, presentation
• Paralinguistics: Tone, pitch, volume, pace

The Body Language Basics

Posture

Closed Posture (Defensive/Uninterested):

• Arms crossed over chest
• Legs crossed away from person
• Shoulders hunched forward
• Body turned away
• Leaning back or away

Open Posture (Engaged/Confident):

• Arms relaxed at sides or gesturing
• Legs uncrossed or crossed toward person
• Shoulders back and down
• Body facing the person
• Leaning slightly forward

Power Poses vs. Submissive Poses

High-Power Poses:

• Standing tall with chest open
• Hands on hips (wonder woman pose)
• Feet shoulder-width apart
• Taking up space
• Expansive gestures

Low-Power Poses:

• Hunched shoulders
• Arms wrapped around body
• Legs crossed tightly
• Making yourself small
• Minimal gestures

Research: Holding a power pose for 2 minutes before important events increases confidence.

Facial Expressions

The Universal 7

These expressions are recognized across all cultures:

Micro-Expressions

Fleeting expressions (less than 1/5 second) that reveal true emotions before we can control them.

How to spot them:

• Watch for quick flashes across face
• Notice expressions that don't match words
• Look for asymmetry (real emotions are usually symmetrical)

Facial Control

Authenticity matters:

• Fake smile: Only mouth moves, doesn't reach eyes
• Real smile (Duchenne): Cheeks lift, eyes crinkle, genuine warmth

Practice: Smile with your eyes. If your cheeks don't raise and outer eye corners don't crinkle, it looks forced.

Eye Contact

The Magic Ratio

Too little eye contact (<40%):

• Appears untrustworthy, nervous, or disinterested
• Signals submission or discomfort

Too much eye contact (>80%):

• Feels aggressive or intense
• Can be perceived as staring

Optimal range: 60-70% of conversation time

Eye Contact Patterns

When speaking:

• 40-60% eye contact
• Look away to think or recall
• Return eye contact when making key points

When listening:

• 70-80% eye contact
• Shows you're engaged and attentive
• Look away briefly to process, not from boredom

The Triangle Technique

Professional settings:

• Imagine triangle from eyes to center forehead
• Shift gaze within this triangle
• Serious, business-like impression

Social settings:

• Imagine triangle from eyes to mouth
• More casual and friendly
• Better for building rapport

Intimate settings:

• Whole face, lingering eye contact
• Reserved for close relationships

Cultural Differences

Western cultures: Direct eye contact = honesty, confidence Some Asian cultures: Less direct eye contact = respect Some Middle Eastern cultures: Extended eye contact between genders inappropriate

Strategy: Observe and mirror the culture you're in.

Gestures

Hand Gestures That Enhance Communication

Open Palm:

• Shows honesty, openness
• "I have nothing to hide"
• Use when building trust

Steepling (Fingertips Touching):

• Shows confidence, authority
• Use when making important points
• Don't overuse (can seem arrogant)

Pointing:

• Use open hand, not finger
• Finger pointing is aggressive
• Gesture to include, not accuse

Counting on Fingers:

• Makes points memorable
• Shows organization
• Helps audience follow along

Gestures to Avoid

The Power of Mirroring

What it is: Subtly matching another person's body language

Benefits:

• Builds rapport unconsciously
• Creates sense of similarity and trust
• Makes others feel understood

How to do it:

• Wait 2-4 seconds before mirroring
• Match general position, not every movement
• Mirror posture, gestures, energy level
• Don't be obvious (they shouldn't notice)

Example:

• They lean forward → You lean forward slightly
• They use hand gestures → You add gestures
• They speak quietly → You lower your volume

Personal Space (Proxemics)

The Four Zones

Intimate Space (0-18 inches):

• Reserved for close relationships
• Family, romantic partners, very close friends
• Invasion causes discomfort or aggression

Personal Space (18 inches - 4 feet):

• Friends and friendly conversations
• Most social interactions
• Comfortable for one-on-one discussions

Social Space (4-12 feet):

• Professional interactions
• New acquaintances
• Business meetings and presentations

Public Space (12+ feet):

• Public speaking
• Addressing groups
• No personal connection expected

Reading Space Preferences

Signs they want more space:

• Leaning back or stepping away
• Creating barriers (crossing arms, holding objects)
• Turning body away
• Breaking eye contact

Signs they're comfortable:

• Leaning in
• Open body language
• Sustained eye contact
• Moving closer

Respect boundaries. When in doubt, maintain more distance.

Touch

Appropriate Professional Touch

Generally acceptable:

• Handshakes (firm but not crushing)
• Brief shoulder touch for emphasis
• Congratulatory pat on upper back

Context-dependent:

• High fives (casual environments)
• Fist bumps (informal settings)
• Brief arm touch when speaking

Avoid:

• Prolonged contact
• Touch on lower back
• Any touch that could be misinterpreted
• Touch when person seems uncomfortable

Handshake Mastery

The Perfect Handshake:

1. Web-to-web contact (between thumb and index finger)
2. Firm grip (not crushing, not limp)
3. 2-3 pumps
4. Eye contact during shake
5. Smile genuinely
6. Release cleanly

Problem handshakes:

• Limp fish: Appears weak, unconfident
• Bone crusher: Aggressive, insecure
• Two-handed: Too intimate for first meeting
• Prolonged: Uncomfortable, over-eager

Appearance and First Impressions

The 7-Second Rule

People form first impressions in 7 seconds or less based on:

• Clothing and grooming
• Facial expression
• Posture and body language
• Eye contact
• Initial greeting

You don't get a second chance at a first impression.

Dress for Context

Business Formal:

• Suit and tie (men)
• Business suit or formal dress (women)
• Conservative colors
• Polished shoes

Business Casual:

• Slacks and collared shirt (men)
• Slacks/skirt and blouse (women)
• No tie required
• Clean, pressed clothing

Casual:

• Clean jeans or khakis
• Neat shirt or sweater
• Context appropriate
• Still polished, not sloppy

Rule of thumb: Dress for the level you aspire to, not where you are.

Reading Others' Nonverbal Cues

Engagement Signals

• Smiling genuinely

Negative signs:

• Leaning back or away
• Looking around or at phone
• Crossed arms/legs
• No facial expression
• Checking watch/phone
• Turning body away

Detecting Deception

No single cue indicates lying. Look for clusters:

Possible deception indicators:

• Inconsistent expressions (saying "yes" while shaking head)
• Touching face, especially nose and mouth
• Decreased eye contact or too much eye contact
• Fidgeting or excessive stillness
• Voice pitch changes
• Micro-expressions of stress

Important: These are stress indicators, not proof of lying. People show stress for many reasons.

Emotional States

Anxiety/Nervousness:

• Fidgeting, touching face/hair
• Shallow breathing
• Avoiding eye contact
• Self-soothing gestures (rubbing arms)

Confidence:

• Open posture
• Steady eye contact
• Controlled gestures
• Taking up space

Anger:

• Clenched jaw or fists
• Red face
• Rigid posture
• Intense stare

Boredom:

• Glazed eyes
• Propping head with hand
• Looking around
• Slumped posture

Interest:

• Leaning in
• Raised eyebrows
• Direct eye contact
• Nodding

Congruence: When Words and Body Don't Match

Incongruence examples:

• Saying "I'm fine" with crossed arms and frown
• Saying "I'm excited" with flat, monotone voice
• Saying "Tell me more" while looking at phone

People believe body language over words.

Your goal: Make sure your nonverbal communication matches your message.

Personal space:

• Latin American and Middle Eastern cultures: closer
