Abstract From the early days of recording nonverbal behavior using 16mm Wlm or paper and pencil reports, significant technological strides have been made. Such advances include the use of video and audio tapes, digital and 8mm recording, computer-driven data collection and analysis, scanning devices—all of which offer greater visual and auditory capture of the nonverbal data; greater clarity, precision, and comparability of data; and improved data storage and analysis than 20 years ago.
