Verbal and Nonverbal Communication

Introduction to Business Communication

Communication is the process of transmitting information from one person (the sender) to another (the receiver) with the aim of achieving mutual understanding. In the business environment, effective communication is a key factor in success: the quality of decision-making, the productivity of teamwork, customer satisfaction, and the overall atmosphere in the organization all depend on it. According to research, managers spend up to 80% of their working time on various forms of communication—meetings, negotiations, writing letters, phone calls, and informal conversations.

Communication in business is not just an exchange of words. It is a complex, multi-level process that includes verbal (spoken) and nonverbal (unspoken) components, each of which contributes to the formation of the message’s meaning. Understanding both channels of communication enables a professional not only to convey their thoughts more accurately but also to better interpret the messages of others.

The Shannon-Weaver Communication Model

One of the most well-known models of communication is the Shannon-Weaver model (1949), originally developed to describe the technical transmission of signals, but later adapted for interpersonal communication. The model includes the following elements:

1. Sender (source) — the person who formulates and transmits the message. In a business context, this may be a manager giving instructions, a salesperson presenting a product, or a colleague sharing information.

2. Encoding — the process of converting thoughts and ideas into a form suitable for transmission (words, gestures, images). The quality of encoding depends on the sender’s vocabulary, communication skills, and understanding of the audience.

3. Message — the encoded information transferred to the receiver. The message can be oral, written, or nonverbal.

4. Channel — the medium for transmitting the message: face to face, telephone, email, videoconference, messenger, written document. The choice of channel significantly affects communication effectiveness.

5. Decoding — the process of interpreting the message by the receiver. Decoding depends on the receiver’s knowledge, experience, cultural context, and emotional state.

6. Receiver — the person to whom the message is addressed and who interprets it.

7. Feedback — the receiver’s reaction, which allows the sender to assess how accurately the message was understood.

8. Noise — any interference that distorts the message. Noise can be physical (loud environment), psychological (prejudices, stress), semantic (different understanding of terms), or organizational (hierarchical barriers).

Understanding this model helps diagnose communication problems. For example, if an employee misunderstood an assignment from a manager, the problem might be in encoding (the manager was unclear), in the channel (the instruction was given by phone in a noisy setting), in decoding (the employee did not know specialized terms), or in the absence of feedback (the manager didn’t check for understanding).

Communication Barriers

There are many barriers to effective communication in business environments:

Language barriers — the use of jargon, professional terms, abbreviations not understood by the interlocutor. For example, an IT specialist explaining a technical problem to a marketer may use terms the latter does not understand.

Psychological barriers — prejudices, stereotypes, emotional states (fear, anger, anxiety), selective perception (people tend to hear what they want to hear).

Physical barriers — noise, distance, technical issues during a videoconference, poor connection quality.

Organizational barriers — hierarchy (subordinates may be afraid to speak openly to a manager), information overload, lack of feedback channels.

Cultural barriers — differences in cultural norms, values, and communication styles. In high-context cultures (Japan, Russia, China), a significant portion of information is transmitted through context rather than direct words. In low-context cultures (USA, Germany), direct, explicit communication is preferred.

Verbal Communication

Verbal communication is the transmission of information via words, both spoken and written. In business communication, the following aspects of verbal communication are important:

Clarity and precision — using concrete, unambiguous phrasing. Instead of “Prepare the report as soon as possible,” it is better to say, “Prepare the sales report for the third quarter by Friday, October 15, by 5:00 PM.”

Adaptation to the audience — choosing language and style depending on the interlocutor. With a technical specialist, you can use professional terminology; with a client, simple and understandable language.

Structure — logical organization of the message: introduction, main part, conclusion. This is especially important during presentations and reports.

Tone and register — formal or informal style, friendly or neutral tone. The choice depends on the situation, the status of the interlocutors, and the corporate culture.

Paraverbal characteristics — vocal features: timbre, speech rate, volume, intonation, pauses. They significantly affect how the message is perceived. Fast speech can create an impression of nervousness or uncertainty, while overly slow speech may signal boredom or condescension. A confident, calm voice increases the speaker’s credibility.

Nonverbal Communication and the Mehrabian Rule

Nonverbal communication is the transmission of information without the use of words. It includes body language, facial expressions, gestures, eye contact, posture, distance between interlocutors, appearance, and other nonverbal signals.

The Mehrabian Rule (7-38-55)

Professor Albert Mehrabian, in his 1967 studies, found that when conveying the emotional content of a message:

• 7% of information is transmitted through words (verbal channel)
• 38% — through tone of voice, intonation (paraverbal channel)
• 55% — through body language, facial expressions (nonverbal channel)

This rule is often misinterpreted as implying words are unimportant. In fact, Mehrabian’s research applied only to situations where verbal and nonverbal channels convey conflicting information—for instance, when someone says, “I’m glad to see you” with a sour expression. In such cases, people tend to trust nonverbal signals more than words. The key takeaway for business communication: ensure congruence (consistency) between verbal and nonverbal messages.

Body Language in Business Communication

Posture. An open posture (shoulders back, relaxed arms) demonstrates confidence, willingness to communicate, and friendliness. A closed posture (arms crossed, slouched shoulders) may signal defensiveness, insecurity, or disagreement. Leaning toward the interlocutor shows interest; leaning back means distancing.

Gestures. In a business context, gestures should be restrained but expressive. Open palms symbolize honesty and openness. Pointing can be perceived as aggressive. Tapping fingers on the table betrays impatience. Touching one’s face, nose, or ear is often associated with insecurity or insincerity (although this is not always the case—context matters).

Facial expressions. The face is the most informative channel of nonverbal communication. Psychologist Paul Ekman identified six universal emotions that are expressed and recognized the same way in all cultures: joy, sadness, anger, fear, surprise, and disgust. In business communication, a sincere smile is especially important (involving the muscles around the eyes—the so-called “Duchenne smile”), which fosters trust and rapport.

Eye contact. Maintaining eye contact demonstrates confidence, honesty, and interest. In Western business culture, maintaining eye contact about 60-70% of the time in conversation is considered optimal. Avoiding eye contact can be perceived as insecurity or insincerity, while too intense a gaze can be seen as aggression or an attempt to dominate. In business negotiations, it is recommended to look at the so-called “business triangle”—the area between the eyes and the middle of the forehead of the interlocutor.

Proxemics

Proxemics is the study of spatial relationships between people during communication. Anthropologist Edward Hall identified four zones of distance:

• Intimate zone (0–45 cm) — for the closest people. In business environments, violating this zone is perceived extremely negatively.
• Personal zone (45–120 cm) — for friendly communication. Acceptable between close colleagues.
• Social zone (120–360 cm) — optimal for most business interactions: negotiations, meetings, communication with clients.
• Public zone (over 360 cm) — for public speeches and presentations.

The choice of distance influences the perception of relationships: too close a distance may cause discomfort; too far—a sense of detachment. It is important to consider cultural differences: in Arab and Latin American cultures, the normal distance of communication is much shorter than in Northern European ones.

Dress as Communication

Appearance and clothing are powerful nonverbal signals in the business environment. Clothing conveys information about status, competence, belonging to a particular social group, and attitude to the situation. The organization’s dress code is, in essence, a system of nonverbal communication that establishes the rules of the company’s “visual language.”

Research shows that formal business attire increases trust in a specialist, especially at the first meeting. However, in technology companies and startups, a formal dress code may be perceived negatively, as a sign of inflexibility and detachment from the corporate culture. The key rule is to dress according to the audience’s expectations and the context of the situation.

Practical Examples from the Business Environment

Example 1: Negotiations with a Partner. The head of the sales department meets with a potential partner. He says the right words about mutually beneficial cooperation but crosses his arms on his chest, avoids eye contact, and leans back in his chair. The partner intuitively senses a mismatch between the words and the body language and begins to doubt the sincerity of the offer. Congruent communication would look like this: open posture, leaning toward the interlocutor, eye contact, nodding—all reinforce the verbal message about readiness to cooperate.

Example 2: Team Meeting. The project manager holds a meeting. He notices that one of the employees, usually active, today sits in a closed posture, looks down, and does not participate in the discussion. Nonverbal signals indicate possible problems: dissatisfaction, stress, or disagreement with the discussed decision. An attentive manager will pay attention to this and talk to the employee privately after the meeting.

Example 3: Presentation for a Client. The product manager presents a new product to a major client. He has prepared excellent slides and carefully worked through the content, but speaks in a monotonous voice, stands motionless behind the podium, and does not establish eye contact with the audience. Despite the high-quality content, the presentation makes little impression. Effective nonverbal delivery would include variations in tone and pace of speech, movement around the stage, gesturing to emphasize key points, and regular eye contact with different members of the audience.

Practical Assignments

Assignment 1

Question: At a meeting with a potential investor, the startup representative delivered a confident speech about the company’s prospects, but constantly touched his face, avoided eye contact, and spoke quickly and quietly. Analyze this situation in terms of communication congruence. What nonverbal signals were sent? How could the investor interpret these signals? What should be changed?

Solution: In this situation, there is incongruence between the verbal and nonverbal channels of communication:

1. Touching the face — is often interpreted as a sign of insecurity, nervousness, or even insincerity. The investor may subconsciously receive this as an indication that the representative does not fully believe in what he is saying.

2. Avoiding eye contact — in Western business culture is associated with insecurity, evasion, or dishonesty. The investor may doubt the reliability of the presented data.

3. Fast speech rate — indicates nervousness, a desire to finish quickly. It creates the impression that the speaker wants to “gloss over” uncomfortable moments.

4. Quiet voice — signals insecurity and weakness of position.

According to Mehrabian’s rule, in a situation of contradiction between verbal and nonverbal messages, the receiver is inclined to trust the nonverbal signals. The investor is likely to interpret the situation as follows: “He is saying the right words, but he doesn’t believe them himself.”

Recommendations for improvement:

• Practice maintaining eye contact (60–70% of conversation time)
• Control gestures: keep hands on the table or gesture with open palms
• Speak at a moderate pace with pauses to emphasize key points
• Increase voice volume to a confident level
• Rehearse the presentation in front of a mirror or on video to achieve congruence

Assignment 2

Question: The company is preparing for a visit from a Japanese delegation to discuss a joint project. What aspects of nonverbal communication should be considered in preparing for the meeting? Consider proxemics, eye contact, gestures, and dress code.

Solution: When preparing for a meeting with a Japanese delegation, it is necessary to take into account the cultural features of nonverbal communication:

Proxemics: In Japanese culture, the distance for communication is usually greater than in European. It is necessary to maintain a social distance (120–150 cm) and avoid physical contact (patting on the shoulder, handshakes—instead, a bow is used). The seating arrangement at the negotiation table should consider hierarchy: senior Japanese representatives usually sit in the center opposite the senior representatives of the host side.

Eye contact: In Japanese culture, prolonged direct eye contact may be perceived as a challenge or sign of disrespect, especially when communicating with people of higher status. It is recommended to maintain soft, periodic eye contact, avoiding a fixed gaze.

Gestures: Japanese business culture calls for restrained gesticulation. Broad gestures, pointing, and showing the soles of shoes should be avoided. Business cards (meishi) are presented and received with both hands and a bow—this is an important ritual, and careless handling of the card will be taken as disrespect.

Dress code: Japanese business culture is traditionally conservative. A strict business style is recommended: dark suit, white or light shirt, conservative tie for men; a strict business suit for women. Bright colors and extravagant accessories are undesirable. Shoes should be clean and tidy (this is given particular attention in Japan).
