“…When people are engaged in a discussion, they automatically converge upon a dialect (Giles, 1973), speaking rate (Street, 1984), speaking speed (Giles, Coupland, Coupland, Williams, & Nussbaum, 1992;Sacks, Schegloff, & Jefferson, 1974), vocal intensity (Natale, 1975), pausing frequency (Cappella & Planalp, 1981), and speech rhythm (Condon, 1976;Condon & Ogston, 1971;Newtson, 1994). They also mimic each other's facial expressions (Kulesza, Dolinski, Wicher, & Huisman, 2016;McHugo, Lanzetta, Sullivan, Masters, & Englis, 1985;Riehle, Kempkensteffen, & Lincoln, 2017). Such nonverbal synchronization cues facilitate the unfolding of the interaction.…”
