During joint tasks, when two or more people interact to accomplish a shared goal, actors coordinate their cognitive processes along with their motor outputs online in order to achieve a shared goal. Spatial-temporal coordination of behavior (e.g., eye movements, postural sway, or limb movements) depends to a large extent on the perceptual-motor systems ability to adapt to changing constraints while supporting joint actions. Soft-assembly of synergies across individuals (interpersonal) and within each individual (intrapersonal) is a common strategy for coping with changes in constraints that can span scales. Synergies at the intrapersonal and interpersonal scales are not independent from one another, but establish rather a system of nested relations in which adjustments in the synergies at the intrapersonal level help support and maintain coordination at the interpersonal level. In spite of the plethora of studies on the emergence and soft assembly of coordinative structures, evidence so far has mainly pointed at how changes in external and internal constraints impact them globally (i.e., changes in overall stability). This talk will introduce the problems of how to better identify and characterize coordinative structures, the changes local relations within structures undergo in response to constraints, and how they impact the efficiency of coordinative relations globally. The advantages and limitations of well-established and newer methodologies for confronting the problem will be discussed. The goal of the talk is to promote discussion on the potential contribution of computational network theory to the study of social coordination.
