Social coordination refers to the process through which individuals adjust and organize their actions, movements, attention, or behaviors in relation to those of others during social interaction ^[1][2]. It enables people to perform joint actions, pursue shared goals, and maintain coordinated patterns of interaction by taking into account the actions and likely responses of other individuals ^[1][3]. Social coordination may involve deliberate planning and communication, as well as spontaneous or implicit forms of interpersonal synchronization that emerge during interaction ^[2][4]. Cognitive and perceptual mechanisms involved in coordination include observing and predicting others’ actions, monitoring ongoing interactions, sharing task-relevant information, and adapting the timing or form of one’s own behavior ^[1][3]. Coordination can occur across different behavioral domains, including motor movements, speech, attention, and other forms of social interaction ^[2][4]. The degree and form of coordination may depend on shared goals, task demands, social relationships, and the characteristics of the interaction. Social coordination therefore encompasses the behavioral and cognitive processes through which people organize their actions with others in space and time.
