The general purpose of the study was to construct a precise explanation of the communication patterns of Korean immigrants in Hawaii and the subsequent impact of these communication patterns on their level of information. A general pattern of communication diversity was conceptualized on two levels: (1) whether an immigrant uses diverse channels of communication rather than depending upon one dominant channel, and (2) whether his communication behavior cuts across ethnic boundaries rather than remaining restricted to just one ethnic group. It was hypothesized that for immigrants to be engaged in diverse communication patterns requires both a greater social capacity and a greater cognitive capacity. The cognitive structure with which immigrants process information from their new environment, and their perceived locus of control over the environment, were used as measures of cognitive capacity. Education, occupational status, length of residence in the United States, and English fluency were used as measures of social capacity. All of the hypothesized relationships were tested and supported by face-to-face interviews in a sample survey of 401 randomly selected Korean immigrants in Hawaii.
