Understand That Nonverbal Communication Is Multichannel

Be aware of the multichannel nature of nonverbal communication. We rarely send a nonverbal message in isolation. For example, a posture may be combined with a touch or eye behavior to create what is called a nonverbal cluster (Pease & Pease, 2004). Nonverbal congruence refers to consistency among different nonverbal expressions within a cluster. Congruent nonverbal communication is more credible and effective than ambiguous or conflicting nonverbal cues. Even though you may intend for your nonverbal messages to be congruent, they could still be decoded in a way that doesn’t match up with your intent, especially since nonverbal expressions vary in terms of their degree of conscious encoding. In this sense, the multichannel nature of nonverbal communication creates the potential of both increased credibility and increased ambiguity.

When we become more aware of the messages we are sending, we can monitor for nonverbal signals that are incongruent with other messages or may be perceived as such. If a student is talking to his professor about his performance in the class and concerns about his grade, the professor may lean forward and nod, encoding a combination of a body orientation and a head movement that conveys attention. If the professor, however, regularly breaks off eye contact and looks anxiously at her office door, then she is sending a message that could be perceived as disinterest, which is incongruent with the overall message of care and concern she probably wants to encode. Increasing our awareness of the multiple channels through which we send nonverbal cues can help us make our signals more congruent in the moment.

Understand That Nonverbal Communication Affects Our Interactions

Nonverbal communication affects our own and others’ behaviors and communication. Changing our nonverbal signals can affect our thoughts and emotions. Knowing this allows us to have more control over the trajectory of our communication, possibly allowing us to intervene in a negative cycle. For example, if you are waiting in line to get your driver’s license renewed and the agents in front of you are moving slower than you’d like and the man in front of you doesn’t have his materials organized and is asking unnecessary questions, you might start to exhibit nonverbal clusters that signal frustration. You might cross your arms, a closing-off gesture, and combine that with wrapping your fingers tightly around one bicep and occasionally squeezing, which is a self-touch adaptor that results from anxiety and stress. The longer you stand like that, the more frustrated and defensive you will become, because that nonverbal cluster reinforces and heightens your feelings. Increased awareness about these cycles can help you make conscious moves to change your nonverbal communication and, subsequently, your cognitive and emotional states (McKay, Davis, & Fanning, 1995).

As your nonverbal encoding competence increases, you can strategically manipulate your behaviors. During my years as a restaurant server I got pretty good at knowing what tables to engage with and “schmooze” a little more to get a better tip. Restaurant servers, bartenders, car salespeople, realtors, exotic dancers, and many others who work in a service or sales capacity know that part of “sealing the deal” is making people feel liked, valued, and important. The strategic use of nonverbal communication to convey these messages is largely accepted and expected in our society, and as customers or patrons, we often play along because it feels good in the moment to think that the other person actually cares about us. Using nonverbals that are intentionally deceptive and misleading can have negative consequences and cross the line into unethical communication.

As you get better at monitoring and controlling your nonverbal behaviors and understanding how nonverbal cues affect our interaction, you may show more competence in multiple types of communication. For example, people who are more skilled at monitoring and controlling nonverbal displays of emotion report that they are more comfortable public speakers (Riggio, 1992). Since speakers become more nervous when they think that audience members are able to detect their nervousness based on outwardly visible, mostly nonverbal cues, it is logical that confidence in one’s ability to control those outwardly visible cues would result in a lessening of that common fear.

Understand How Nonverbal Communication Creates Rapport

Humans have evolved an innate urge to mirror each other’s nonverbal behavior, and although we aren’t often aware of it, this urge influences our behavior daily (Pease & Pease, 2004). Think, for example, about how people “fall into formation” when waiting in a line. Our nonverbal communication works to create an unspoken and subconscious cooperation, as people move and behave in similar ways. When one person leans to the left the next person in line may also lean to the left, and this shift in posture may continue all the way down the line to the end, until someone else makes another movement and the whole line shifts again. This phenomenon is known as mirroring, which refers to the often subconscious practice of using nonverbal cues in a way that match those of others around us. Mirroring sends implicit messages to others that say, “Look! I’m just like you.” Mirroring evolved as an important social function in that it allowed early humans to more easily fit in with larger groups. Logically, early humans who were more successful at mirroring were more likely to secure food, shelter, and security and therefore passed that genetic disposition on down the line to us.

Last summer, during a backyard game of “corn hole” with my family, my mom and sister were standing at the other board and kept whispering to each other and laughing at my dad and me. Corn hole, which is also called “bags,” involves throwing a cloth sack filled with corn toward another team’s board with the goal of getting it in the hole or on the board to score points. They later told us that they were amazed at how we stood, threw our bags, and shifted position between rounds in unison. Although my dad and I didn’t realize we were doing it, our subconscious mirroring was obviously noticeable to others. Mirroring is largely innate and subconscious, but we can more consciously use it and a variety of other nonverbal signals, like the immediacy behaviors we discussed earlier, to help create social bonds and mutual liking.

Understand How Nonverbal Communication Regulates Conversations

The ability to encode appropriate turn-taking signals can help ensure that we can hold the floor when needed in a conversation or work our way into a conversation smoothly, without inappropriately interrupting someone or otherwise being seen as rude. People with nonverbal encoding competence are typically more “in control” of conversations. This regulating function can be useful in initial encounters when we are trying to learn more about another person and in situations where status differentials are present or compliance gaining or dominance are goals. Although close friends, family, and relational partners can sometimes be an exception, interrupting is generally considered rude and should be avoided. Even though verbal communication is most often used to interrupt another person, interruptions are still studied as a part of chronemics because it interferes with another person’s talk time. Instead of interrupting, you can use nonverbal signals like leaning in, increasing your eye contact, or using a brief gesture like subtly raising one hand or the index finger to signal to another person that you’d like to soon take the floor.

Understand How Nonverbal Communication Relates to Listening

Part of being a good listener involves nonverbal-encoding competence, as nonverbal feedback in the form of head nods, eye contact, and posture can signal that a listener is paying attention and the speaker’s message is received and understood. Active listening, for example, combines good cognitive listening practices with outwardly visible cues that signal to others that we are listening. We will learn more about active listening in Chapter 5 “Listening”, but we all know from experience which nonverbal signals convey attentiveness and which convey a lack of attentiveness. Listeners are expected to make more eye contact with the speaker than the speaker makes with them, so it’s important to “listen with your eyes” by maintaining eye contact, which signals attentiveness. Listeners should also avoid distracting movements in the form of self, other, and object adaptors. Being a higher self-monitor can help you catch nonverbal signals that might signal that you aren’t listening, at which point you could consciously switch to more active listening signals.

Understand How Nonverbal Communication Relates to Impression Management

The nonverbal messages we encode also help us express our identities and play into impression management, which as we learned in Chapter 1 “Introduction to Communication Studies” is a key part of communicating to achieve identity goals. Being able to control nonverbal expressions and competently encode them allows us to better manage our persona and project a desired self to others—for example, a self that is perceived as competent, socially attractive, and engaging. Being nonverbally expressive during initial interactions usually leads to more favorable impressions. So smiling, keeping an attentive posture, and offering a solid handshake help communicate confidence and enthusiasm that can be useful on a first date, during a job interview, when visiting family for the holidays, or when running into an acquaintance at the grocery store. Nonverbal communication can also impact the impressions you make as a student. Research has also found that students who are more nonverbally expressive are liked more by their teachers and are more likely to have their requests met by their teachers (Mottet et al., 2004).

Increase Competence in Specific Channels of Nonverbal Communication

While it is important to recognize that we send nonverbal signals through multiple channels simultaneously, we can also increase our nonverbal communication competence by becoming more aware of how it operates in specific channels. Although no one can truly offer you a rulebook on how to effectively send every type of nonverbal signal, there are several nonverbal guidebooks that are written from more anecdotal and less academic perspectives. While these books vary tremendously in terms of their credibility and quality, some, like Allan Pease and Barbara Pease’s The Definitive Book of Body Language, are informative and interesting to read.

There Is No Nonverbal Dictionary

The first guideline for decoding nonverbal communication is to realize that there is no nonverbal dictionary. Some nonverbal scholars and many nonverbal skill trainers have tried to catalog nonverbal communication like we do verbal communication to create dictionary-like guides that people can use to interpret nonverbal signals. Although those guides may contain many valid “rules” of nonverbal communication, those rules are always relative to the individual, social, and cultural contexts in which an interaction takes place. In short, you can’t read people’s nonverbal communication like a book, and there are no A-to-Z guides that capture the complexity of nonverbal communication (DePaulo, 1992). Rather than using a list of specific rules, I suggest people develop more general tools that will be useful in and adaptable to a variety of contexts.

Recognize That Certain Nonverbal Signals Are Related

The second guideline for decoding nonverbal signals is to recognize that certain nonverbal signals are related. Nonverbal rulebooks aren’t effective because they typically view a nonverbal signal in isolation, similar to how dictionaries separately list denotative definitions of words. To get a more nuanced understanding of the meaning behind nonverbal cues, we can look at them as progressive or layered. For example, people engaging in negative critical evaluation of a speaker may cross their legs, cross one arm over their stomach, and put the other arm up so the index finger is resting close to the eye while the chin rests on the thumb (Pease & Pease, 2004). A person wouldn’t likely perform all those signals simultaneously. Instead, he or she would likely start with one and then layer more cues on as the feelings intensified. If we notice that a person is starting to build related signals like the ones above onto one another, we might be able to intervene in the negative reaction that is building. Of course, as nonverbal cues are layered on, they may contradict other signals, in which case we can turn to context clues to aid our interpretation.

Although cultural patterns exist, people also exhibit idiosyncratic nonverbal behavior, meaning they don’t always follow the norms of the group.

Read Nonverbal Cues in Context

We will learn more specifics about nonverbal communication in relational, professional, and cultural contexts in Section 4.1 “Principles and Functions of Nonverbal Communication”, but we can also gain insight into how to interpret nonverbal cues through personal contexts. People have idiosyncratic nonverbal behaviors, which create an individual context that varies with each person. Even though we generally fit into certain social and cultural patterns, some people deviate from those norms. For example, some cultures tend toward less touching and greater interpersonal distances during interactions. The United States falls into this general category, but there are people who were socialized into these norms who as individuals deviate from them and touch more and stand closer to others while conversing. As the idiosyncratic communicator inches toward his or her conversational partner, the partner may inch back to reestablish the interpersonal distance norm. Such deviations may lead people to misinterpret sexual or romantic interest or feel uncomfortable. While these actions could indicate such interest, they could also be idiosyncratic. As this example shows, these individual differences can increase the ambiguity of nonverbal communication, but when observed over a period of time, they can actually help us generate meaning. Try to compare observed nonverbal cues to a person’s typical or baseline nonverbal behavior to help avoid misinterpretation. In some instances it is impossible to know what sorts of individual nonverbal behaviors or idiosyncrasies people have because there isn’t a relational history. In such cases, we have to turn to our knowledge about specific types of nonverbal communication or draw from more general contextual knowledge.

Interpreting Cues within Specific Channels

When nonverbal cues are ambiguous or contextual clues aren’t useful in interpreting nonverbal clusters, we may have to look at nonverbal behaviors within specific channels. Keep in mind that the following tips aren’t hard and fast rules and are usually more meaningful when adapted according to a specific person or context. In addition, many of the suggestions in the section on encoding competence can be adapted usefully to decoding.

Detecting Deception

Although people rely on nonverbal communication more than verbal to determine whether or not a person is being deceptive, there is no set profile of deceptive behaviors that you can use to create your own nonverbally based lie detector. Research finds that people generally perceive themselves as good detectors of deception, but when tested people only accurately detect deception at levels a little higher than what we would by random chance. Given that deception is so widespread and common, it is estimated that we actually only detect about half the lies that we are told, meaning we all operate on false information without even being aware of it. Although this may be disappointing to those of you reading who like to think of yourselves as human lie detectors, there are some forces working against our deception detecting abilities. One such force is the truth bias, which leads us to believe that a person is telling the truth, especially if we know and like that person. Conversely, people who have interpersonal trust issues and people in occupations like law enforcement may also have a lie bias, meaning they assume people are lying to them more often than not (Andersen, 1999).

It is believed that deceptive nonverbal behaviors result from nonverbal leakage, which refers to nonverbal behaviors that occur as we try to control the cognitive and physical changes that happen during states of cognitive and physical arousal (Hargie, 2011). Anxiety is a form of arousal that leads to bodily reactions like those we experience when we perceive danger or become excited for some other reason. Some of these reactions are visible, such as increased movements, and some are audible, such as changes in voice pitch, volume, or rate. Other reactions, such as changes in the electrical conductivity of the skin, increased breathing, and increased heart rate, are not always detectable. Polygraph machines, or lie detectors, work on the principle that the presence of signs of arousal is a reliable indicator of deception in situations where other factors that would also evoke such signals are absent.

So the nonverbal behaviors that we associate with deception don’t actually stem from the deception but the attempts to control the leakage that results from the cognitive and physiological changes. These signals appear and increase because we are conflicted about the act of deception, since we are conditioned to believe that being honest is better than lying, we are afraid of getting caught and punished, and we are motivated to succeed with the act of deception—in essence, to get away with it. Leakage also occurs because of the increased cognitive demands associated with deception. Our cognitive activity increases when we have to decide whether to engage in deception or not, which often involves some internal debate. If we decide to engage in deception, we then have to compose a fabrication or execute some other manipulation strategy that we think is believable. To make things more complicated, we usually tailor our manipulation strategy to the person to whom we are speaking. In short, lying isn’t easy, as it requires us to go against social norms and deviate from our comfortable and familiar communication scripts that we rely on for so much of our interaction. Of course, skilled and experienced deceivers develop new scripts that can also become familiar and comfortable and allow them to engage in deception without arousing as much anxiety or triggering the physical reactions to it (Andersen, 1999).

There is no one “tell” that gives away when someone is lying.

There are certain nonverbal cues that have been associated with deception, but the problem is that these cues are also associated with other behaviors, which could lead you to assume someone is being deceptive when they are actually nervous, guilty, or excited. In general, people who are more expressive are better deceivers and people who are typically anxious are not good liars. Also, people who are better self-monitors are better deceivers, because they are aware of verbal and nonverbal signals that may “give them away” and may be better able to control or account for them. Research also shows that people get better at lying as they get older, because they learn more about the intricacies of communication signals and they also get more time to practice (Andersen, 1999). Studies have found that actors, politicians, lawyers, and salespeople are also better liars, because they are generally higher self-monitors and have learned how to suppress internal feelings and monitor their external behaviors.
