We report the results of a study investigating speakers' and addressees' coordination of understanding in face-to-face narrative dialogue. Analyses of the occurrence of addressees' acknowledgments and exemplifications of understanding showed that nonverbal forms consistently coincided with the speakers' gaze on their face. In contrast, there was less consistent correspondence between the addressees' verbal evidence of understanding and the speakers' gaze on their face. Evidence that speakers gaze off addressees' faces because of the demands of utterance planning or encoding comes from a correspondence between their gaze off the addressee's face and their production of pause fillers (uh and um), especially at the beginning of clauses.
