“…Dyadic synchrony involves coordinated and co-regulated exchanges between people; it is a property of interaction rather than a property of individuals or relationships (Harrist & Waugh, 2002). Dyadic synchrony is independent of positive affect (Harrist & Waugh, 2002), includes both verbal and nonverbal cues (Ivy & Gleason, 2022; Knobloch & Solomon, 2003), and is evaluated positively by interactants (Ebesu Hubbard, 2000).
