This study, one of a series investigating dyadic infracommunication in natural, academic, and laboratory settings, utilizes a simple observation technique such as that employed by anthropologists living among members of a society or subcultural group, observing and recording their behavior patterns, including their communication modes. Subjects were male and female pupils in a desegregated elementary school with a student body composed of 32 per cent lower class blacks and 68 per cent middle class whites. The sample ratio was 42 per cent black and 48 per cent white. Interpersonal distance and angle of orientation, gaze direction, status, position, locomotion, sex, race, smile, and audible communication of dyadic subjects were the variables observed. A simple observation technique was used to gather data, with the observer present--sitting or standing in the least conspicuous place available. Subjects were not aware of the nature of observer's interest and recording. Selection of dyads for observation was made by the sequential scan method, with the observer noting the nearest pupil. Five hundred dyads were observed. (Authors/JM)
