Studies rarely have taken the differences that cultural nuances can play in social penetration, particularly when it is between two cultures which are either high context or low context. However, it was found that social penetration theory is generalizable to North American-Japanese Dyads. Generally, and across different levels of intimacy within these dyads, the theory holds true.  This was further supported when comparing the research to the highest level of inimitacy marital communication. The same held to be true when it came to analyzing the level of intimacy between different dyads across the spctrum, but it was found that “the results from the analysis of the dispersion scores revealed that mixed dyads had significantly less agreement than low intimacy dyads on the amount of personalized communication and less, but not significantly less, agreement than low intimacy dyads.” Therefore, conflict came more from differences in intimacy, rather than differences in the context within a culture. This study also found that opposite sex dyads were more generally more personalized than same-sex dyads, regardless of culture.There was some interesting correlational research also found during this study which merged with the work of Knapp, Ellis, and Williams (1980) intracultural research. Perceived difficulty of communication had a high negative correlation, suggesting that as communicative difficulty is reduced, a relationship may grow. The opposite was found to be true. This further suggested that perceived communication difficulties, such as the balancing act between the need for intimacy with disclosure versus the need for privacy. This will hinder communication regardless of the culture or cultural dyads in place.
