William S Condon


William S Condon b. 1934, unconfirmed

W. S. Condon began his research in human communication in 1964 using a frame-by-frame video recording (1/25th of a second) to analyse people talking (and listening) in conversation, an area that maintained his interest for decades of future research. Through his pioneering research Condon noticed ‘self-synchrony’, that the speaker’s interlocking systems worked rhythmically; and that there were movements that seemed to co-occur between those of the listener and the speaker, called ‘interactional synchrony’. In his quest to help define gesture, Condon’s video observations could extend beyond those noticed by the naked eye, including micro movements. He recorded segments of body movement, and this microanalysis allowed for the two apparently disparate systems to be studied in terms of how they integrate (co-occur) during speech and organizations of change in movement (correlated with articulatory changes), as well as movement during pauses and silences.
