Chronemics is the study of the role of time in communication. It is one of several subcategories of the study of nonverbal communication. Other prominent subcategories include haptics (touch), kinesics (body movement), vocalics (paralanguage), and proxemics (the use of space).
Thomas J. Bruneau of Radford University coined the term "chronemics" in the late 1970s to help define the function of time in human interaction:
Chronemics can be briefly and generally defined as the study of human tempo as it related to human communication. More specifically, chronemics involves the study of both subjective and objective human tempos as they influence and are interdependent with human behavior. Further, chronemics involves the study of human communication as it relates to interdependent and integrated levels of time-experiencing. Previously, these interdependent and integrated levels have been outlined and discussed as: biological time; psychological time; social time; and cultural time. A number of classification systems exist in the literature of time. However, such systems are not applied to human interaction directly.
Chronemics can be defined as "the interrelated observations and theories of man's use of time" – the way in which one perceives and values time, structures time, and reacts to time frames communication. Time perception plays a large role in the nonverbal communication process. Time perceptions include punctuality, willingness to wait, and interactions. The use of time can affect lifestyle, daily agendas, speed of speech, movements, and how long people are willing to listen.
Time can be used as an indicator of status. For example, in most companies the boss can interrupt progress to hold an impromptu meeting in the middle of the work day, yet the average worker would have to make an appointment to see the boss. The way in which different cultures perceive time can influence communication as well.
Cultures are sometimes considered monochronic or polychronic.
A monochronic time system means that things are done one at a time and time is segmented into precise, small units. Under this system, time is scheduled, arranged and managed.
The United States considers itself a monochronic society. This perception came about during the Industrial Revolution, when "factory life required the labor force to be on hand and in place at an appointed hour" (Guerrero, DeVito & Hecht, 1999, p. 238). Many Americans like to think that to them, time is a precious resource not to be wasted or taken lightly. "We buy time, save time, spend time and make time. Our time can be broken down into years, months, days, hours, minutes, seconds and even milliseconds. We use time to structure both our daily lives and events that we are planning for the future. We have schedules that we must follow: appointments that we must go to at a certain time, classes that start and end at certain times, work schedules that start and end at certain times, and even our favorite TV shows, that start and end at a certain time."
