As an example of “culture-specific” communication research, the present study investigated “self-disclosure” during initial interaction within Japanese culture. Presented with a simulated conversation containing varying levels of self-disclosure, a total of 192 Japanese males and females filled out several scale items measuring episode perception, social attractiveness and communication competence of the discloser, and strength of logical force. While respondents generally rated a low level of self-disclosure positively, the results also indicated a significant dialogue-by-sex interaction effect on the episode and person perception variables. With regard to logical force, the results showed that the strength of prefigurative force varied little, except for cultural archetype-act linkage, whereas practical force differed as a function of self-disclosure level. Implications of these findings are further discussed within the context of Japanese culture.
