Internet communication is nicreasing due to PCs and mobile phones.　In a college, we conducted
a survey in terms of the aspects of self-disclosure and self-concealment and the nature of awareness
with which people use catual and online communications.　It was shown that there was a strong
tendency to avoid the unambiguous communication of personal ideas and feelings due to prioritizing
smooth interpersonal relationships with friends with whom the face-to-face communication was
implemented.
