ABSTRACT. The purpose of this study was to compare the amount of information sent by the speaker, received and retrieved by the listener in inter-and intra-cultural conversations. Three hypotheses were tested: (1) in their conversations, inter-cultural interactants would communicate signi®cantly less information than intra-cultural interactants with other variables held constant, (2) the two inter-cultural conditions would not be dierent from each other in terms of the amount of information communicated, and the same would be true with the two intra-cultural conditions, and (3) in their conversations, the speakers in inter-cultural conditions would send the same amount of information as speakers in intracultural conditions given that all speakers would pass a test on the materials they were going to present. Participants were 40 Canadian and 40 Chinese university students, and they were randomly assigned to one of the four experimental conditions. Each dyad engaged in two medical conversations, which were videotaped upon the consent of the participants. The nature of the conversations resembled physician-patient face-to-face interactions. Results from written tests immediately following the conversations provided strong support for Hypothesis 1 and 2, and results from viewing the videotapes provided partial support for Hypothesis 3. In relation to the amount of information sent by the speakers, listeners in inter-and intra-cultural conditions retrieved only 50% and 75% of the information respectively. Based on the ®ndings, one may argue that inter-cultural communication differs signi®cantly from intra-cultural communication in the amount of information Int. J. Intercultural Rel.
