In this paper we discuss a cross-cultural analysis of non-verbal expressions (gestures, facial expressions, body posture) that have a turn managing function in the flow of interaction. The study was carried out by analyzing and comparing the features of interest in two samples of institutional interaction, namely face-to-face political interviews, in Greek and Icelandic respectively. The non-verbal behavior of the participants in both interviews was annotated following the same annotation process. The attested turn management instances were compared in order to find similarities and differences in terms of frequency and modality preference.
