Ray Birthwhistell b. 1918

Ray L Birthwhistell coined the terms kinesics (meaning ‘the study of body‐motion as related to the non‐verbal aspects of interpersonal communication’) and kine (the smallest observable unit of body movement). He saw that a small number of movement types combined to form larger structural units. Birthwhistell established kinesics as a field of enquiry and research to which he contributed for 20 years analysing people talking and examined how their gestures were used to emphasise and illustrate. His in-depth observation led to him proposing a set of categories that characterised movements witnessed (kinesics) making identifiable social actions. He believed body‐motion communication to be systemic, socially learned and communicative behaviours unless proven otherwise, and argued that human communication needs and uses all the senses. Birthwhistell estimated that no more than about a third of the social meaning of a conversation (or interaction) is carried by the words. He proposed that gestures and movements convey information that is coded and patterned differently in various cultures; and that people’s preferred or typical postures reflected their past.
