When a mob has the power to move people to act and forms to surge together down a street to move groups to act together. In order one way and then another, when a flock for language to act as a force, it must of birds wheels about together, closely somehow affect people with sufficient clustered as they fly without colliding; social and emotional impact. As and when an orchestra performs with Nusbaum discusses the impact of highly coordinated timing, we language, it operates at a social and momentarily forget about the individuals emotional level similar to that discussed and see the collective behavior as a new, by Semin rather than exclusively single social entity. Indeed, as Cacioppo through the inferences drawn from discusses, many species seem to gather, meaning. flock, and coordinate to form such collectives. For humans there are many situations from flash mobs and sports teams to choirs and audiences, when people congregate in this way. The drive for people to affiliate and group is not sufficient on its own to produce the coordinated behavior that emerges from such a collective. Sometimes an organizing signal, like the conductor of an orchestra, can synchronize the behavior. Other times common goals and behavioral constraints can synchronize a group, as in a flock of birds. In his chapter, Giin Semin discusses how such synchrony may be self-organizing — that is, it is achieved without intention, effort, or awareness by our social brains, even when there is no clear signal or constraint. In cases of such human sociality, the group may act as though it has a single mind. Indeed, Semin approaches this issue t
