Verbal and Nonverbal Communication: Differences and Examples

Three channels, one moment

Picture a video call where the microphone keeps working but the camera freezes for a few seconds: you still hear the words, yet something is clearly missing. That’s because a face-to-face conversation carries several distinct channels at once. Verbal communication is the linguistic content itself, the words and sentences that make up the message. Paraverbal communication covers how those words get said: tone, speaking rate, intensity, pauses. Nonverbal communication, finally, covers the elements that weave into the verbal part without being made of words at all: facial expressions, movement, posture, physical distance. The topic sits close to psychological science, which studies these exchanges with observational methods and controlled experiments, trying to work out how much weight each channel actually carries in a given situation.

These channels can confirm each other or clash: a smile during “I’m happy to see you” confirms the message; the same smile during “I’m angry at you” undercuts it.

Verbal communication: the content

Verbal communication is the mode expressed through words, the purely linguistic layer of the message. It’s the easiest layer to write down: a sentence on a page carries only this channel, stripped of tone and gesture. In speech, words almost always arrive dressed in how they are said and in what the speaker’s body is doing at the same time.

Practical example: the phrase “thank you so much” typed in a text message communicates only its literal content. The same phrase said out loud, with a warm tone and a smile, also communicates genuine gratitude; said with a flat tone and a gaze looking elsewhere, it can communicate the exact opposite.

Paraverbal communication: tone, rhythm, pauses

What school curricula call paraverbal communication corresponds, in the Treccani Encyclopedia of Italian, to a set of features that shape how a message gets spoken: rhythm, speaking rate, tone, intensity and pauses. The voice gives form to words already chosen, adding a layer that a written text never carries.

A pause before answering an awkward question signals hesitation, even when the words that follow sound confident. A tone that rises toward the end of a statement turns it, to the listener’s ear, into something close to a question. The literal meaning of the words stays identical; what changes, almost every time, is what the listener actually takes away.

Nonverbal communication: kinesics

American anthropologist Ray Birdwhistell founded kinesics as a field of study dedicated to facial expressions, gestures, posture, gait and the visible movements of arms and body. His core claim was that words weren’t the only vehicle for meaning in a conversation: a substantial share of what gets communicated would travel through channels outside vocabulary.

Birdwhistell went as far as estimating that the social meaning of a conversation passed through words in a minority share, around 30-35%, leaving the rest to other channels. It’s an estimate of the same kind, and with the same limits on how far it generalizes, as the better-known figure attributed to Mehrabian discussed further down: a number that only describes the setting where it was gathered, not a universal measure. Birdwhistell himself, for that matter, warned against reading a single body movement in isolation: a gesture makes sense alongside the rest of someone’s behavior, never on its own. Picking up on these cues in someone else’s face is also one of the ingredients of emotional intelligence, the ability to notice and manage emotions in oneself and others.

Proxemics: the space that communicates

Nonverbal communication also covers how people manage physical space. Proxemics, a field introduced by anthropologist Edward T. Hall in 1963, studies how different cultures use space and physical distance in interaction. Observing Western culture, Hall distinguished four zones of interpersonal distance:

These figures belong to the cultural context Hall observed. That very observation is where proxemics gets its core idea: what counts as an appropriate distance shifts from one culture to another. Standing 50 centimeters from a stranger during a conversation feels natural in some cultures and intrusive in others, and neither reaction is wrong on its own terms.

The 93% myth: what Mehrabian really said

Few figures in the social sciences have been as widely misread as the 7%-38%-55% formula attributed to Albert Mehrabian. In its original formulation, this formula describes how a speaker’s overall perceived liking is composed: it concerns the communication of feelings and attitudes, in the specific cases where words, tone and face are in conflict with each other, not a general measure of how well any communication “works”.

The original experiments, run in 1967, were tightly scoped: single words spoken with a positive or negative tone, only female participants, no measurement of posture at all. That’s a narrow sample next to the reach the rule later gained in popular culture, where it often circulates as “93% of every message is nonverbal.” Mehrabian himself noted that his percentages apply only to the specific context in which words and nonverbal signals express feelings, and that the rule has been widely misapplied in training and popular writing.

Practical example: reading furniture assembly instructions aloud doesn’t fit the case Mehrabian studied. There, the verbal content (the instructions) matters enormously, because there’s no conflicting feeling for tone or expression to resolve.

When channels meet or clash

The three channels travel together in every live conversation, almost never in isolation. When they tell the same story, the message lands coherently: calm words, calm tone, relaxed posture add up without friction. When one channel contradicts another, kind words spoken in a sharp tone, or an “I’m fine” said with hunched shoulders, the listener notices the mismatch, even without always being able to put it into words.

Making sense of this distinction doesn’t mean memorizing body language gesture by gesture, the way some popular lists promise. It means remembering that a gesture only makes sense alongside everything else, inside the context where it happens. Birdwhistell and Mehrabian reached that same warning from opposite corners of the field. Much of this behavior, besides, isn’t learned from a manual: people pick it up by watching others from childhood on, not unlike other habits studied by Bandura’s social learning theory.
