Oculesics

From Wikipedia, the free encyclopedia
The word ocu is often used interchangeably with eye contact. However, there are other dimensions of oculesics. See below.

Oculesics, a subcategory of kinesics, is the study of eye movement, eye behavior, gaze, and eye-related nonverbal communication. The specific definition varies depending on whether it applies to the fields of medicine or social science.[1][2]

Introduction

As a social or behavioral science, oculesics is a form of nonverbal communication focusing on deriving meaning from eye behavior.

It can also deal with the medical care of eyes, such as optometry and ophthalmology. The term "oculist" usually applies to a doctor of one of these medical specialties.

The word oculesics comes from the word oculus, which is Latin for eye. It is a combination of the Latin prefix ocul(o)- meaning of or pertaining to the eye, and the Latin suffix -ica & Greek suffix -ικά meaning organized knowledge or treatment.

Nonverbal Communication

Oculesics is one form of nonverbal communication, which is the transmission and reception of meaning between communicators without the use of words. It can include the environment around the communicators, the physical attributes or characteristics of the communicators, and the behavior of the communicators.[3]

The four nonverbal communication cues are spatial, temporal, visual and vocal. Each relates to one or more forms of nonverbal communication:[4]

  • Chronemics - the study of time
  • Haptics - the study of touch
  • Kinesics - the study of movement
  • Oculesics - the study of eye behavior
  • Olfactics - the study of scent
  • Paralanguage - the study of voice communication outside of language
  • Proxemics - the study of space

Dimensions of Oculesics

There are four aspects involved with oculesics:[5]

Dimension 1: Eye Contact

There are three levels of eye contact:[1]

  • Direct eye contact
  • Indirect eye contact
  • Duration of eye contact

Dimension 2: Eye Movement

Eye Movement occurs voluntarily or involuntarily. It can include changing eye direction, changing focus, or following objects with the eyes.[6]

Dimension 3: Pupil Dilation

Pupillary response

Pupillary response is change in the size of the pupil, voluntarily or involuntarily. This change happens at the appearance of real or perceived new objects of focus, and even at the real or perceived indication of such appearances[7]

Dimension 4: Gaze Direction

Gazing deals with communicating and feeling intense desire with the eye, voluntarily or involuntarily.[8]

Theorists and Studies

Many theorists and studies are associated with nonverbal communication, to include oculesics.

Ray Birdwhistell

Professor Ray Birdwhistell was one of the earliest theorists of nonverbal communication. As an anthropologist, he created the term kinesics, and defined it as communication and perceived meaning from facial expressions and body gestures.[9]

Birdwhistell spent over fifty years analyzing kinesics. He wrote two books on the subject: Introduction to Kinesics (1952) and Kinesics and Context (1970). He also created films of people communicating and studied their methods of nonverbal communication in slow-motion. He published his results as attempts to make general translations of gestures and expressions, although he later acknowledged it was impossible to equate each form of body language with a specific meaning.[10]

Birdwhistell's study of oculesics was greatly enhanced by his use of film. In one study, he would film specifically in which directions and at what objects children looked as they learned activities from their parents.[11]

Paul Ekman

Dr. Paul Ekman is a psychologist with over five decades experience researching nonverbal communication, especially with facial expressions. He has written, co-authored and edited over a dozen books, and published over 100 articles on the subject.[12] He also served as an advisor for the television show Lie to Me, and currently works with the Dalai Lama on increasing awareness of the influence of emotion on behavior to help people reach peace of mind.[13][14]

Dr. Ekman's work in facial expressions includes studies looking for connections between oculesics and other facial movements,[15] eye behavior and physically covering the eyes when recalling personal traumatic events,[16] and on his self-coined phrase, "the Duchenne smile" (named after Guillaume Duchenne), which relates to involuntary movements of the orbicularis oculi, pars orbitalis when smiling sincerely.[17] Most prominently, oculesics play a major role in the Facial Action Coding System (FACS), which is a microexpression database created by Dr. Ekman and his colleagues.[18]

W. Gerrod Parrott

Dr. W. Gerrod Parrott is a Professor of Psychology at Georgetown University in Washington, DC. His focus is on human emotions and how they affect our thought processes.[19] In his paper Positioning and the Emotions, he discusses the concept of counter-argument, in which a communicator projects an emotion to a receiver in an attempt to illicit a specific emotion, but the receiver instead projects a different emotion to deflect or disrupt the original intentions of the communicator.[20] Oculesics can play a major part in these emotional projection strategies.

Robert Plutchik

Professor Robert Plutchik (21 October 1927 - 29 April 2006) was a psychologist who specialized in communicating emotion with expressions and gestures.[21][22] Many of his articles and books discuss the influence of emotion on nonverbal communication as well as the affect of those expressions and gestures back onto emotions.[23]

Professor Plutchik's work on oculesics includes studies on the "synthesis of facial expressions," which look for connections between expressions in the eye along with expressions from the forehead and mouth.[24]

Eye Movement Desensitization and Reprocessing

Eye Movement Desensitization and Reprocessing (EMDR) is a form of therapy created by Dr. Francine Shapiro to help treat conditions such as Post-traumatic Stress Disorder (PTSD).[25][26] EMDR uses eye movement to communicate within the subject in an attempt to re-create meaning and processing of past traumatic events.[27]

Communicating Emotions

In the book Human Emotions, author Carroll Ellis Izard says "a complete definition of emotion must take into account all three of these aspects or components: (a) the experience or conscious feeling of emotion, (b) the processes that occur in the brain and nervous system, and (c) the observable expressive patterns of emotion, particularly those on the face" (p. 4).[28] This third component is where oculesics plays a role in nonverbal communication of emotion.

Oculesics is a primary form of communicating emotion.[29] The study of Neurolinguistic Programming (NLP) establishes three main types of thinking: in terms of what you see, hear or feel. According to this science, oculesics can show which type of thinking someone is using when they are communicating.[30] A person thinking visually might physically turn their eyes away, as if to look at an imagined presentation of what they are thinking, even to the point of changing the focus of their eyes. Someone thinking in terms of hearing might turn their eyes as much as possible to one of their ears. A person thinking in terms of what they feel could look downwards, as if looking toward their emotion coming from their body.[30]

Whether or not someone intends to send a particular meaning, or someone else perceives meaning correctly, the exchange of communication happens and can initiate emotion. It is important to understand these dynamics, because we often establish relationships (on small and grand scales) with oculesics.[29]

Lists of Emotions

Main article: Contrasting and categorization of emotions

There are many theories on how to annotate a specific list of emotions. Two prominent methodologies come from Dr. Paul Ekman and Dr. Robert Plutchik (both professors are referenced above as well).

Dr. Ekman states there are 15 basic emotions- amusement, anger, contempt, contentment, disgust, embarrassment, excitement, fear, guilt, pride in achievement, relief, sadness/distress, satisfaction, sensory pleasure, and shame- with each of these fifteen stemming out to similar and related sub-emotions.[31]


Dr. Plutchik says there are eight basic emotions which have eight opposite emotions, all of which create human feelings (which also have opposites). He created Plutchik's Wheel of Emotions to demonstrate this theory.[32]

Perceptions and displays of emotions vary across time and culture. Some theorists say that even with these differences, there can be generally-accepted "truths" about oculesics, such as the theory that constant eye contact between two people is physically and mentally uncomfortable.[33]

The following emotions and their associated eye behaviors come from Changing Minds.org:

Emotions w/ eye summary:[34]

  • Anxiety - wetness or moisture in the eyes
  • Anger - eyes glaring and wide open
  • Boredom - eyes not focused, or focused on something else
  • Desire - eyes wide, dilation of pupils
  • Disgust - rapid turning away of eyes
  • Envy - glaring
  • Fear - eyes could be wide, or looking downward (could also be closed)
  • Happiness - "glittery" look to eyes, wrinkled at the sides
  • Interest - intense focus, perhaps squinting
  • Pity - heavy gaze to eyes, moisture in eyes
  • Sadness - tears in eyes, looking downward (also possible sleepless appearance[35])
  • Shame - eyes looking down while head is turned down
  • Surprise - eyes wide open

Eye behaviors with emotional summaries:[36]

  • Eyes up - Different people look up for different reasons. Some look up when they are thinking. Others perform that action in an effort to recall something from their memory. It may also be a way for people to subconsciously display boredom. The head position can also come into play, however, as an upwards look with a lowered head can be a coy, suggestive action.
  • Eyes down - Avoiding eye contact, or looking down, can be a sign of submission or fear. It may also indicate that someone feels guilt. However, depending on the culture of the person, it may also just be a sign of respect.
  • Lateral movement of eyes - Looking away from the person to whom one is speaking could be a sign that something else has taken their interest. It may also mean that a person is easily distracted. Looking to the left can mean that a person is trying to remember sound, while the right can mean that the person is actually imagining the sound. Side to side movement, however, can indicate that a person is lying.
  • Gazing - Staring at someone means that a person shows sincere interest. Staring at a person's lips can indicate that someone wants to kiss another person. In general, staring means, "I want that."
  • Glancing - Glancing can show a person's true desires. For instance, glancing at a door might mean that someone wants to leave. Glancing at a glass of water might mean that a person is thirsty.
  • Eye contact - Eye contact is powerful and shows sincere interest if it is unbroken. A softening of the stare can indicate sexual desire. Breaking that eye contact can be threatening to the person who does not break the eye contact.
  • Staring - Staring is more than just eye contact, it usually involves eyes wider than normal. A lack of blinking may indicate more interest, but it also may indicate a stronger feeling than a person may intend to portray. Prolonged eye contact can be aggressive, affectionate, or deceptive.
  • Following with the eyes - Eyes follow movement naturally. If a person is interested in someone, than their eyes will follow that person naturally.
  • Squinting - Squinting of the eyes may mean a person is trying to obtain a closer look. It may also mean that a person is considering whether something is true or not. Liars may use squinting as a tool to keep others from detecting their dishonesty. Of course, squinting may also just be a result of a bright sun.
  • Blinking - Blinking is also a natural response that can occur for no other reason than having dry eyes. It can also be the result of a person feeling greater levels of stress. Rapid blinking can indicate arrogance while reduced blinking can move towards a stare.
  • Winking - Winking can indicate that two people understand something without using words. It can mean "hello" or it can be a sign of flirtation.
  • Closing of eyes - Closing the eyes serves to shut out the world. It can be a reaction to fear or embarrassment. Others may close their eyes as a way to think more sincerely about a particular subject.
  • Eye moisture - Tears obviously indicate sadness, but moisture also has a more practical purpose to wash and clean the eyes. Damp eyes can be suppressed crying or an expression of extreme happiness or laughter. Men, in many cultures, are not expected to cry but may experience damp eyes in place of crying.
  • Pupil dilation - Pupil dilation may be harder to detect by most people. Sexual desire may be a cause of such dilation. It may also be an indication of attraction. Physiologically, eyes dilate when it is darker to let in more light.
  • Rubbing of eyes - Eyes may water, causing a person to rub their own eyes. This can happen when a person feels uncomfortable or tired. It may also happen when a person simply has something in their eyes.

Cultural Impact

Cultural Differences in Nonverbal Communication

In his essay The Coordinated Management of Meaning (CMM), Dr. W.Barnett Pearce discusses how people derive meaning in communication based on reference points gained or passed down to them culturally.[37]

Someone once said, “To know a language and not the culture is to make a fluent fool of yourself.” [38] Culture in this sense, includes all of the nonverbal communication, customs, thought, speech and artifacts that make a group of people unique.[39] Whoever said this statement knew of the significant role that communication plays besides language. While most of the nonverbal communication is conveyed subconsciously, there are cultural similarities that enable us to understand the difference between what is being said and what is actually meant. But generalizing between nonverbal communication between cultures can be tricky since there are as many cultural differences in nonverbal communication as there are languages in the world.[38]

While it may take a child a couple of years to speak understandably in a certain language, it is important to remember that the child is also learning the idiosyncrasies of nonverbal communication at the same time. In fact, the first couple of years of a child’s life are spent learning most of these nonverbals. The differences between cultures are thus ingrained at the very earliest points of development.

Projected Similarity

Anthropologists have proven for years that nonverbal communication styles vary by culture. Most people, however, are not only oblivious to the differences in these nonverbal communication styles within their own culture, but they also assume that individuals from other cultures also communicate in the same way that they do. This is a phenomenon called projected similarity.[40] The result of projected similarity is that misperceptions, misinterpretations, and misunderstandings occur in cross-cultural interactions when a person interprets another’s non- verbal communication in the light of his or her own cultural norms.[40]

While all nonverbal communication differs greatly among cultures, perhaps none is so obviously different than the movement and study of eye contact. A particular nonverbal interaction between two individuals can have completely different meaning in different cultures. Even within that same culture, oculesics plays a tremendous role in obtaining meaning from other nonverbal cues. This is why, even among the same culture, humans still have trouble sometimes understanding each other because of they varying eye behavior, nonverbal cues, and cultural and personal differences.[38]

Stereotypes in Cultural Differences

It is because of these personal differences, that in studying cultural communication patterns we sometimes find it necessary to speak in stereotypes and generalizations. Just as one might say that Puerto Ricans who speak Spanish tend to use a louder voice than others communicating at the same distance, it would not be fair to say that all Puerto Ricans exhibit the same qualities. There are obviously enormous variations within each culture. These variations can depend on age, gender, geographical location, race, socioeconomic status, and personality. Because there are so many factors to study, most are generally glossed over in favor of stereotypes and generalizations.[40]

Some Oculesic Findings from around the World

As previously discussed, the effect that eye movement has on human behavior has been widely studied. In some cultures, however, this study actually allows for insights into individuals whose only way of communication is by nonverbal means. Studies show that eye behavior shows special patterns with mental patients, autistic children, and persons from diverse cultures.[38] In some countries, doctors use the study of oculesics to test stimulation among patients and interest levels in children who are not as expressive verbally. While lack of eye contact in many cultures can signal either disinterest or respect, depending on the culture of the individual, it may be an insight into a mental patient’s brain functions on a particular day.[38]

Latin American Culture vs. Anglo Saxon Culture

There are many differences between Anglo Saxon culture and Latino culture, both in the way the two groups interact with each other as well as the way they interact with members of other cultural groups. Besides the obvious language differences, nonverbal communication is the most noticeable difference between the two groups. Specifically within nonverbal communication, eye contact and eye behavior can actually help one differentiate between the cultural backgrounds of two individuals by looking at nothing but their eyes.

Sociologists have found that Anglos tend to look steadily and intently into the eyes of the person to whom they are speaking. Latinos will look into the eyes of the person to whom they are speaking, but only in a fleeting way.[40] The Latino tends to look into the other person’s eyes and then immediately allow his or her eyes to wander when speaking. In traditional Anglo Saxon culture, averting the eyes in such a way usually portrays a lack of confidence, certainty, or truthfulness.[40] However, in the Latino culture, direct or prolonged eye contact means that you are challenging the individual with whom you are speaking or that you have a romantic interest in the person.[40]

Imagine the confusion that this slight difference can cause in professional situations such as an interview. If an Anglo Saxon individual was interviewing a Latino for a position and found the person to be lacking confidence because of their lack of eye contact, the Latino would lose out on the employment opportunity solely because of the cultural differences. Imagine, also, how uncomfortable the Latino would feel during the interview because he or she may interpret the Anglo’s direct eye contact as expressing disapproval. These kinds of cultural differences occur every day and cause unnecessary mixed signals to be sent because of the lack of knowledge of another individual’s culture.

Muslim Culture

In the Islamic faith, most Muslims lower heads and try not to focus on the opposite sex's features except for the hands and face. This is a show of respect but also a cultural rule which enforces Islamic law. Lustful glances to those of the opposite sex are also prohibited.<ref name='Sheikh Riyâd al-Musaymîrî>Al-Musaymîrî, Riyâd Dr. (2011). "Men & women speaking together without temptation". IslamToday - English.  (Retrieved 6 June 2012)</ref>

Western Pacific Nations

Many western pacific nations share much of the same cultural customs. Children, for instance, are taught in school to direct their eyes to their teacher's Adam's apple or tie knot. This continues through adulthood, as most Asian cultures lower their eyes when speaking to a superior as a gesture of respect.[41]

East Asia and Northern Africa

In many East Asian and north African cultures such as Nigeria,[6] it is also respectful not to look the dominant person in the eye. The seeking of constant unbroken eye contact by the other participant in a conversation can often be considered overbearing or distracting- even in western cultures.[42]

United States

In the United States, eye contact may serve as a regulating gesture and is typically related to issues of respect, attentiveness, and honesty in the American culture. Americans associate direct eye contact with forthrightness and trustworthiness.[43]

Dealing With Cultural Differences

So how do you deal with these cultural differences? How does one recognize to which culture a particular person identifies so that he or she will infer correctly all of the nonverbal cues associated with that culture? From such a potentially complicated question comes a relatively simple answer. Study, listen and learn. Communicators and leaders become successful because they observe the unconscious actions of others. Sometimes an individual’s actions are the result of their culture or upbringing and sometimes they are the result of the emotion or feeling they are portraying. Keen communicators are able to tell the difference between the two and effectively communicate based on their observations. Oculesics is not a standalone science. Combining the information obtained from eye movements and behaviors with other nonverbal cues such as Haptics, Kinesics, or Olfactics will lend the observer to a much more well rounded and accurate portrait of an individual’s behavior.[40]

Social scientists teach that individuals need to first become consciously aware of their own culture before being able to interpret differences among other cultures. In learning about our own culture, we learn how we are different from the cultures of those around us. Only then, will we become aware of the differences among the cultures of others. Finally, we should undergo acculturation,[40] that is, borrow attributes from other cultures that will help us function effectively without in any way having to relinquish our own cultural identities. In Nonverbal Communication, Nine-Curt stresses that “we should develop, refine, and constantly practice the skill of switching cultural channels, as on a TV set, in order to be able to interact with people from other cultures, and oftentimes with people from subcultures within our own, more effectively. This is indispensable if we are to avoid the pain, frustration, and discomfort that usually accompany trying to move and live in a culture different from our own. As we become proficient in this skill, we will find it less difficult and highly satisfying to accept others and their styles of living.[40]

Medical Field

Ophthalmology

Main article: Ophthalmology

Ophthalmology is the medical science specializing in the health of eyes and vision. Ophthalmologists are authorized to oversee all aspects of the medical treatment of eyes and eye disease. This field requires a medical degree and three years in residency. eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery.[44]

Optometry

Main article: Optometry

Optometry is a profession dealing with visual health care. Optometrists are licensed to refract for and prescribe glasses, fit and prescribe contact lenses, examine, diagnoses and treat eye conditions and diseases, including cataracts, macular degeneration, glaucoma, dry eyes and many other diseases. They can treat most eye diseases but cannot perform surgery. They are doctors of Optometry, not medicine. This field requires an undergraduate degree, plus four years in the college of optometry.[44]
