Nonverbal Behavior

One way that the participants in the studies described above may have been able to form such accurate impressions of instructors on the basis of such little information was by viewing their nonverbal behavior. Nonverbal behavior is any type of communication that does not involve speaking, including facial expressions, body language, touching, voice patterns, and interpersonal distance. Nonverbal behaviors are used to reinforce spoken words (Hostetter, 2011) but also include such things as interpersonal distance (how far away from you the other person stands), tone of voice, eye gaze, and hand gestures and body positions (DePaulo et al., 2003).

The ability to decode nonverbal behavior is learned early, even before the development of language (Walker-Andrews, 2008). We tend to like people who have a pleasant tone of voice and open posture, who stand an appropriate distance away from us, and who look at and touch us for the “right” amount of time—not too much or too little. And, of course, behavior matters; people who walk faster are perceived as happier and more powerful than those who walk more slowly (Montepare & Zebrowitz-McArthur, 1988). (For more insight into the relationship between nonverbal communication and success, see social psychologist Amy Cuddy’s fascinating TED Talk.

The importance of body movement has been demonstrated in studies in which people are viewed in point-light displays in dark rooms with only small lights at their joints. Research has found that observers are able to accurately recognize the behavior of others from these minimal displays (Clarke, Bradshaw, Field, Hampson, & Rose, 2005; Johnson, Gill, Reichman, & Tassinary, 2007; Heberlein, Adolphs, Tranel, & Damasio, 2004; Figure 5.4). People can also determine personality by tone of voice provided by degraded and incomprehensible speech (Ambady, Krabbenhoft, & Hogan, 2006).

People can accurately detect behaviors, emotions, and traits from point-light displays. You might want to try your skills here.

Although they may be pretty good at it in some cases, people are often not aware of their ability to make accurate judgments. Rule, Ambady, Adams, and Macrae (2008) found that even though the participants in their research were quite accurate in their perceptions, they could not articulate how they made their judgments. They claimed that they were “just guessing” and could hardly believe that they were getting the judgments right. These results suggest that they were made without any conscious awareness on the part of the judgers. Furthermore, the participants’ judgments of their own accuracy were not generally correlated with their actual accurate judgments.

Nonverbal behaviors are an important form of communication—and they are particularly important in expressing our liking of, and caring for, others. 

The particular nonverbal behaviors that we use, as well as their meanings, are determined by social norms, and these norms may vary across cultures. For example, people who live in warm climates nearer the equator use more nonverbal communication (e.g., talking with their hands or showing strong facial expressions) and are more likely to touch each other during conversations than people who live in colder climates nearer Earth’s poles (Manstead, 1991; Pennebaker, Rime, & Blankenship, 1996). And the appropriate amount of personal space to keep between ourselves and others also varies across cultures. In some cultures—for instance, those of South American countries—it is appropriate to stand very close to another person while talking to him or her; in other cultures—for example, in the United States and Western Europe—more interpersonal space is the norm (Knapp & Hall, 2006). The appropriate amount of eye contact with others is also determined by culture. In Latin America, it is appropriate to lock eyes with another person, whereas in Japan, people more often try to avoid eye contact.

Although nonverbal behaviors can be informative during the initial stages of person perception, they are limited in what they can convey. In general, they communicate our own status or dominance (self-concern) as well as our interest in or liking of another (other-concern). If we notice that someone is smiling and making eye contact with us while leaning toward us in conversation, we can be pretty sure that he or she likes us. On the other hand, if someone frowns at us, touches us inappropriately, or moves away when we get close, we may naturally conclude that he or she does not like us.

We may also use nonverbal behaviors to try out new situations: If we move a little closer and look at someone a bit longer, we communicate our interest. If these responses are reciprocated by the other person, that can indicate that he or she likes us, and we can move on to share other types of information. If the initial nonverbal behaviors are not reciprocated, then we may conclude that the relationship may not work out and we can withdraw before we go “too far.”

Nonverbal behavior provides different information than verbal behavior because people frequently say one thing and do another. Perhaps you remember being really angry at someone but not wanting to let on that you were mad, so you tried to hide your emotions by not saying anything. But perhaps your nonverbal behavior eventually gave you away to the other person: although you were trying as hard as you could not to, you just looked angry. We frequently rely more on nonverbal than on verbal behavior when messages are contradictory. One reason for this is that we know that it is relatively easy to monitor our verbal behavior but harder to control the nonverbal. However, we expect that people who need to deceive others—for instance, good poker players—are able to monitor their nonverbal behavior better than most people, making it difficult to get a good read on them.

Because we use nonverbal behaviors so frequently in our social interactions, we are fluent readers of them. We also realize that we can better communicate with others when we use them. Indeed, it is difficult to communicate accurately when we cannot express ourselves nonverbally (Krauss, Chen, & Chawla, 1996). You probably have noticed this yourself. If you e-mail or text a message to your friend, for instance, you need to be careful about using sarcasm because he or she might misinterpret your meaning. Because nonverbal information is so important, we quickly learned to incorporate it, in the form of emoticons, in our text messages (Figure 5.6).
