Gestures

Emblems

Many gestures are emblems. Emblems are gestures that have a specific agreed-on meaning. Only a handful of emblematic gestures seem to be universal, for example, a shrug of the shoulders to indicate “I don’t know.” Most emblems are culturally determined, and they can get you into difficulty if you use them in other countries. In the United States, some emblematic gestures are the thumb-up-and-out hitchhiking sign, the circled thumb and index finger Ok sign, and the “V” for victory sign. However, be careful of using these gestures outside the United States. The thumb-up sign in Iran, for example, is an obscene gesture, and our Ok sign has sexual connotations in Ethiopia and Mexico. 

Illustrators

While emblems can be used as direct substitutions for words, illustrators help emphasize or explain a word. Illustrators are the most common type of gesture and are used to illustrate the verbal message they accompany. For example, you might use hand gestures to indicate the size or shape of an object. Unlike emblems, illustrators do not typically have meaning on their own and are used more subconsciously than emblems. These largely involuntary and seemingly natural gestures flow from us as we speak but vary in intensity and frequency based on context. Although we are never explicitly taught how to use illustrative gestures, we do it automatically. Think about how you still gesture when having an animated conversation on the phone even though the other person can’t see you.

Affect Displays

Affect displays show feelings and emotions. Consider how music and sports fans show enthusiasm. It is not uncommon to see people jumping up and down at sports events during a particularly exciting moment in a game. However, there are different norms depending on the sport. It would simply be inappropriate to demonstrate the same nonverbal gestures at a golf or tennis game as a football game.

Regulators

Regulators, as discussed earlier, are gestures that help coordinate the flow of conversation, such as when you shrug your shoulders or wink. Head nods, eye contact/aversion, hand movements, and changes in posture are considered to be turn-taking cues in conversation. Individuals may sit back when listening but shift forward to indicate a desire to speak. Eye contact shifts frequently during a conversation to indicate listening or a desire to speak. Head nods are used as a sign of listening and often indicate that the speaker should continue speaking.

Head Movements and Posture

Head movements and posture are grouped together because they are often both used to acknowledge others and communicate interest or attentiveness. In terms of head movements, a head nod is a universal sign of acknowledgment in cultures where the formal bow is no longer used as a greeting. In these cases, the head nod essentially serves as an abbreviated bow. An innate and universal head movement is shaking back and forth to signal “no.” This nonverbal signal begins at birth, even before a baby can know that it has a corresponding meaning. Babies shake their heads from side to side to reject their mother’s breast and later shake their heads to reject attempts to spoon-feed (Pease & Pease, 2004). This biologically based movement then sticks with us as a recognizable signal for “no.” We also move our heads to indicate interest. For example, a head up typically indicates an engaged or neutral attitude, a head tilt indicates interest and is an innate submission gesture that exposes the neck and subconsciously makes people feel more trusting of us, and a head down signals a negative or aggressive attitude (Pease & Pease, 2004).

There are four general human postures: standing, sitting, squatting, and lying down (Hargie, 2011). Within each of these postures, there are many variations, and when combined with particular gestures or other nonverbal cues they can express many different meanings. Most of our communication occurs while we are standing or sitting. One interesting standing posture involves putting our hands on our hips and is a nonverbal cue that we use subconsciously to make us look bigger and show assertiveness. When the elbows are pointed out, this prevents others from getting past us as easily and is a sign of attempted dominance or a gesture that says we’re ready for action. In terms of sitting, leaning back shows informality and indifference, straddling a chair is a sign of dominance (but also some insecurity because the person is protecting the vulnerable front part of his or her body), and leaning forward shows interest and attentiveness (Pease & Pease, 2004).

Eye Contact

We also communicate through eye behaviors, primarily eye contact. While eye behaviors are often studied under the category of kinesics, they have their own branch of nonverbal studies called oculesics, which comes from the Latin word oculus, meaning “eye.” The face and eyes are the main points of focus during communication, and along with our ears, our eyes take in most of the communicative information around us. The saying “The eyes are the window to the soul” is actually accurate in terms of where people typically think others are “located,” which is right behind the eyes (Andersen, 1999). Certain eye behaviors have become tied to personality traits or emotional states, as illustrated in phrases like “hungry eyes,” “evil eyes,” and “bedroom eyes.” To better understand oculesics, we will discuss the characteristics and functions of eye contact and pupil dilation.

Eye contact serves several communicative functions ranging from regulating and monitoring interaction, to conveying information, to establishing interpersonal connections. In terms of regulating communication, we use eye contact to signal to others that we are ready to speak, or we use it to cue others to speak. I’m sure we’ve all been in that awkward situation where a teacher asks a question, no one else responds, and he or she looks directly at us as if to say, “What do you think?” In that case, the teacher’s eye contact is used to cue us to respond. During an interaction, eye contact also changes as we shift from speaker to listener. US Americans typically shift eye contact while speaking—looking away from the listener and then looking back at his or her face every few seconds. Toward the end of our speaking turn, we make more direct eye contact with our listener to indicate that we are finishing up. While listening, we tend to make more sustained eye contact, not glancing away as regularly as we do while speaking (Martin & Nakayama, 2010).

Our eyes monitor interaction by bringing in the visual information we need to interpret people’s movements, gestures, and eye contact. A speaker can use his or her eye contact to determine if an audience is engaged, confused, or bored and then adapt his or her message accordingly. Our eyes also send information to others. People know not to interrupt when we are in deep thought because we naturally look away from others when processing information. Making eye contact with others also communicates that we are paying attention and are interested in what another person is saying. Eye contact is a key part of active listening.

Eye contact can also be used to intimidate others. We have social norms about how much eye contact we make with people, and those norms vary depending on the setting and the person. Staring at another person in some contexts could communicate intimidation, while in other contexts it could communicate flirtation. As we learned, eye contact is a key immediacy behavior, and it signals to others that we are available for communication. Once communication begins, if it does, eye contact helps establish rapport or connection. We can also use our eye contact to signal that we do not want to make a connection with others. For example, in a public setting like an airport or a gym where people often make small talk, we can avoid making eye contact with others to indicate that we do not want to engage in small talk with strangers. Another person could use eye contact to try to coax you into speaking, though. For example, when one person continues to stare at another person who is not reciprocating eye contact, the person avoiding eye contact might eventually give in, become curious, or become irritated and say, “Can I help you with something?” As you can see, eye contact sends and receives important communicative messages that help us interpret others’ behaviors, convey information about our thoughts and feelings, and facilitate or impede rapport or connection.

Facial Expressions

Our faces are the most expressive part of our bodies. Think of how photos are often intended to capture a particular expression “in a flash” to preserve for later viewing. Even though a photo is a snapshot in time, we can still interpret much meaning from a human face caught in a moment of expression, and basic facial expressions are recognizable by humans all over the world. Much research has supported the universality of a core group of facial expressions: happiness, sadness, fear, anger, and disgust. The first four are especially identifiable across cultures (Andersen, 1999). However, the triggers for these expressions and the cultural and social norms that influence their displays are still culturally diverse. If you’ve spent much time with babies, you know that they’re capable of expressing all these emotions. Getting to see the pure and innate expressions of joy and surprise on a baby’s face is what makes playing peek-a-boo so entertaining for adults. As we get older, we learn and begin to follow display rules for facial expressions and other signals of emotion and also learn to better control our emotional expression based on the norms of our culture.

Smiles are powerful communicative signals and, as you’ll recall, are a key immediacy behavior. Although facial expressions are typically viewed as innate, and several are universally recognizable, they are not always connected to an emotional or internal biological stimulus; they can actually serve a more social purpose. For example, most of the smiles we produce are primarily made for others and are not just an involuntary reflection of an internal emotional state (Andersen, 1999). These social smiles, however, are slightly but perceptibly different from more genuine smiles. People generally perceive smiles as more genuine when the other person smiles “with their eyes.” This particular type of smile is difficult to fake because the muscles around the eye that are activated when we spontaneously or genuinely smile are not under our voluntary control. It is the involuntary and spontaneous contraction of these muscles that moves the skin around our cheeks, eyes, and nose to create a smile that’s distinct from a fake or polite smile (Evans, 2001). People are able to distinguish the difference between these smiles, which is why photographers often engage in cheesy joking with adults or use props with children to induce a genuine smile before they snap a picture.

We all have varying definitions of what our “personal space” is, and these definitions are contextual and depend on the situation and the relationship. Although our bubbles are invisible, people are socialized into the norms of personal space within their cultural group. Scholars have identified four zones for US Americans, which are public, social, personal, and intimate distance (Hall, 1968). The zones are more elliptical than circular, taking up more space in our front, where our line of sight is, than at our side or back, where we can’t monitor what people are doing. You can see how these zones relate to each other and the individual below. Even within a particular zone, interactions may differ depending on whether someone is in the outer or inner part of the zone.

Territoriality

Territoriality is an innate drive to take up and defend spaces. This drive is shared by many creatures and entities, ranging from packs of animals to individual humans to nations. Whether it’s a gang territory, a neighborhood claimed by a particular salesperson, your preferred place to sit in a restaurant, your usual desk in the classroom, or the seat you’ve marked to save while getting concessions at a sporting event, we claim certain spaces as our own. There are three main divisions for territory: primary, secondary, and public (Hargie, 2011). Sometimes our claim to a space is official. These spaces are known as our primary territories because they are marked or understood to be exclusively ours and under our control. A person’s house, yard, room, desk, side of the bed, or shelf in the medicine cabinet could be considered primary territory.

Secondary territories don’t belong to us and aren’t exclusively under our control, but they are associated with us, which may lead us to assume that the space will be open and available to us when we need it without us taking further steps to reserve it. This happens in classrooms regularly. Students often sit at the same desk or at least the same general area as they did on the first day of class. There may be some small adjustments during the first couple of weeks, but by a month into the semester, students do not typically move often voluntarily. When someone else takes a student’s regular desk, they are typically annoyed.

Public territories are open to all people. People are allowed to mark public territory and use it for a limited period of time, but space is often up for grabs, which makes public space difficult to manage for some people and can lead to conflict. To avoid this type of situation, people use a variety of objects that are typically recognized by others as nonverbal cues that mark a place as temporarily reserved—for example, jackets, bags, papers, or a drink. There is some ambiguity in the use of markers, though. A half-empty cup of coffee may be seen as trash and thrown away, which would be an annoying surprise to a person who left it to mark his or her table while visiting the restroom. One scholar’s informal observations revealed that a full drink sitting on a table could reserve a space in a university cafeteria for more than an hour, but a cup only half full usually only worked as a marker of territory for less than ten minutes. People have to decide how much value they want their marker to have. Obviously, leaving a laptop on a table indicates that the table is occupied, but it could also lead to the laptop getting stolen. A pencil, on the other hand, could just be moved out of the way and the space usurped.
