During question-and-answer sessions after a presentation, in which the presenter responds to questions from the audience and exchanges opinions with the audience, there are often periods of silence. This article analyzes international students' behavior during periods of silence in their question-and-answer sessions. Results showed that while relatively long periods of silence, which interrupted the conversation, occurred when students searched for slides on their computer, the most frequent periods of silence were less than one second and involved non-verbal communication such as 'making gestures' 'changing one's posture', and 'looking at the audience'. Furthermore, there were periods of silence which indicated a 'pause until the next utterance'.
