Method of micro-analysis of sound films of behavior

Initial viewings of sound films of human behavior resulted in the problem of how to divide the seemingly continuous flow of that behavior. This led to the development of methods and instrumentation that would permit variable-contrast scanning of the processes in order to detect points and criteria of segmentation. Since both speech and body motion are to be studied, instruments that would permit the analysis of each at a commensurate level were required. The instruments are primarily combinations of commercially available equipment that is relatively inexpensive yet reliable. These instruments, their use, and some of the preliminary observations are presented.
