“…Few studies have attempted to induce physiological synchrony by changing how people see themselves relative to others (for an exception, see Kraus & Mendes, 2014). Most studies examine the emergence of physiological synchrony as a function of relationship type (e.g., parent-child synchrony as a function of relationship quality; Baker, et al, 2015), social experience (e.g., synchrony between audience and performers at a dance recital; Bachrach, Fontbonne, Joufflineau, & Ulloa, 2015), or some combination of relationship type and social experience (e.g., mother-infant synchrony after exposing mother to a stressor; Waters, et al, 2014). Our study is the first to demonstrate that manipulating perceptions of social identity can increase physiological synchrony between relative strangers.…”
