The purpose of the present research was to investigate the relationships among normative consciousness, individual traits, and the frequency of private conversations, in the form of whispering, amongst students during a college lecture. In the first study, the relationships among normative consciousness against whispering, perspective taking, social skills, and the frequency of whispering were examined through a questionnaire survey consisting of 251 respondents. The results showed that students who whispered frequently indicated high perspective taking or social skills. In the second study, the relationships among the goals of college life, normative consciousness, and the frequency of whispering were focused upon. The relationships between whispering and feelings of adjustment were also investigated. A questionnaire survey was conducted, and 369 responses were obtained. The results showed the following. (1) Despite having a high normative consciousness, students who valued the development of interpersonal relationships during college life were more likely to have conversations irrelevant to the lecture. (2) There were positive relationships between whispering and feelings of interpersonal adjustment.
