A group of university students consisting of native speakers of Chinese (n=63), Japanese (n=33), Korean (n=21), Indonesian (n=20), and Arabic (n=13) with relatively extensive exposure to the American university environment and a control group of 20 native English-speakers were asked to rank the social appropriateness of 104 conversation topics. Group responses were analyzed for correlation across language groups. Topics were clustered in these categories: family and family members; age (own and family); classes/grades/teachers; hearer (possessions, self, etc.); money (own/family); own possessions; life in the United States; recreation/weather/travel; self (tastes, experiences); and residence. Results show high correlation in judgments of topics pertaining to family and to classes/grades/teachers. There was less agreement about the appropriateness of topics pertaining to age, money, the hearer, personal possessions, life in the United States, recreation, self, and residence. The questionnaire and data summaries for topic clusters are appended. Contains 26 references. (Author/MSE)
