According to tightness-looseness theory, ecological and human-made threats increase the need for strong social coordination mechanisms among individuals for survival (Gelfand et al., 2011; Harrington & Gelfand, 2014). However, the neural mechanism of threat effect on social coordination remains unclear. The current study examined how territorial threats modulated interpersonal synchrony in a social coordination game by using hyperscanning electroencephalography. Chinese participants who were under ingroup territorial threat priming showed more synchronous behavior with their partners as compared to those who were under outgroup territorial threat and no threat control priming conditions. Moreover, ingroup territorial threats increased social coordination via modulating interbrain neural activities at multiple frequency bands. To be noted, the gamma interbrain synchrony mediated the effect of threat on interpersonal synchrony behavior. These results illustrate the important role of threat in fostering synchronous behavior via coupling interbrain neural activity.
