• Abstract This research builds on previous work showing that interpersonal synchrony in dyads is a social cue that informs bystanders about the dyads’ psychological attributes and influences their intentions to affiliate with members of dyads. Across two studies, participants were asked to observe dyads walking down a corridor during the TV show Shark Tank , rate the dyads’ collective efficacy, and express their own intentions to affiliate with them. The results replicate and extend previous work, suggesting that perceived synchrony, collective efficacy, and affiliation intentions are positively correlated, and that perceived synchrony can have positive spill-over effects on outcomes such as attracting business proposals and being liked by others.
