All animals communicate and many animals make meaningful sounds. Others use visual signs, such as facial expressions, color changes, body postures and movements, light (fireflies), or electricity (some eels). Many use the sense of smell and the sense of touch. Most animals use a combination of two or more of these systems in their communication, but their systems are closed systems in that they cannot create new meanings or messages. Human communication is an open system that can easily create new meanings and messages. Most animal communication systems are basically innate; they do not have to learn them, but some species’ systems entail a certain amount of learning. For example, songbirds have the innate ability to produce the typical songs of their species, but most of them must be taught how to do it by older birds.

Great apes and other primates have relatively complex systems of communication that use varying combinations of sound, body language, scent, facial expression, and touch. Their systems have therefore been referred to as a gesture-call system. Humans share a number of forms of this gesture-call, or non-verbal system with the great apes. Spoken language undoubtedly evolved embedded within it. All human cultures have not only verbal languages, but also non-verbal systems that are consistent with their verbal languages and cultures and vary from one culture to another. We discuss the three most important human non-verbal communication systems – kinesics, proxemics, and paralanguage.

4.1.1 Kinesics: Body Language

Kinesics includes all forms of human body language, including gestures, body position and movement, facial expressions, and eye contact. Although all humans can potentially perform these in the same way, different cultures may have different rules about how to use them. For example, eye contact for Americans is highly valued as a way to show we are paying attention and as a means of showing respect. But for the Japanese, eye contact is usually inappropriate, especially between two people of different social statuses. The lower status person must look down and avoid eye contact to show respect for the higher status person.

Facial expressions can convey a host of messages, usually related to the person’s attitude or emotional state. Hand gestures may convey unconscious messages, or constitute deliberate messages that can replace or emphasize verbal ones.

4.1.2 Proxemics: Study of Social Use of Space

Proxemics is the study of the social use of space, specifically the distance an individual tries to main- tain around himself in interactions with others. The size of the “space bubble” depends on a number of social factors, including the relationship between the two people, their relative status, their gender and age, their current attitude toward each other, and above all their culture. In some cultures, such as in Brazil, people typically interact in a relatively close physical space, usually along with a lot of touching. Other cultures, like the Japanese, prefer to maintain a greater distance with a minimum amount of touching or none at all. If one person stands too far away from the other according to cultural stan- dards, it might convey the message of emotional distance. If a person invades the culturally recognized space bubble of another, it could mean a threat. Or, it might show a desire for a closer relationship. It all depends on who is involved.

I (Vanessa) remember taking a college trip to Russia and traveling on a train. The train was packed and everyone was struggling to find space. While most of the Americans were uncomfortable and complaining, the majority of Russians seemed relaxed and accustomed to the limited space. Such a difference from trying to catch a bus in Sunderland, Massachusetts to get to the University of Massachusetts. I had to ask someone to move their book bag from a seat because the Americans seemed to think that they needed a large space bubble on a crowded bus. How would you define your “space bubble” in relation to others and when? How much of your “space bubble” is informed by your culture and when might you decide to push the space bubble?

4.1.3 Paralanguage: Speech Beyond Words

Paralanguage refers to those characteristics of speech beyond the actual words spoken. These include the features that are inherent to all speech: pitch, loudness, and tempo or duration of the sounds. Varying pitch can convey any number of messages: a question, sarcasm, defiance, surprise, confidence or lack of it, impatience, and many other often subtle connotations. An utterance that is shouted at close range usually conveys an emotional element, such as anger or urgency. A word or syllable that is held for an undue amount of time can intensify the impact of that word. For example, compare “It’s beautiful” versus It’s beauuuuu-tiful!” Often the latter type of expression is further emphasized by extra loudness of the syllable, and perhaps higher pitch; all can serve to make a part of the utterance more important. Other paralinguistic features that often accompany speech might be a chuckle, a sigh or sob, deliberate throat clearing, and many other non-verbal sounds like “hm,” “oh,” “ah,” and “um.”

Most non-verbal behaviors are unconsciously performed and not noticed unless someone violates the cultural standards for them. In fact, a deliberate violation itself can convey meaning. Other non-verbal behaviors are done consciously like the U.S. gestures that indicate approval, such as thumbs up, or making a circle with your thumb and forefinger—“OK.” Other examples are waving at someone or putting a forefinger to your lips to quiet another person. Many of these deliberate gestures have different meanings (or no meaning at all) in other cultures. For example, the gestures of approval in U.S. culture mentioned above may be obscene or negative gestures in another culture.
