This study analyzed differences between native and nonnative English speakers in how they deliver dispreferred responses during a debate. The study found that native speakers emphasized agreement more at the beginning and were more indirect at the end when disagreeing. Nonnative speakers' responses were more direct throughout. As interactions progressed, both groups became more direct, though nonnatives remained more so. These findings suggest it is important for English language teaching to include conversation strategies to help nonnatives interact successfully with native speakers.
