Distributed cognition refers to situations in which task requirements are distributed among multiple agents or, potentially, off-loaded onto the environment. The idea assumes that the cognitive system is flexibly composed of various CNS components as well as non-neural bodily and environmental components, including other agents. Important to understanding distributed cognition is a consideration of how cognitive components become coordinated, and whether multi-agent cognitive coordination yields as a single cognitive system—an emergent, interpersonal cognitive synergy.
Synergies are organizations of anatomical (and, potentially, environmental) components into a single, functional unit, such that the components work together and regulate one another to promote task performance. Synergies exhibit reciprocal compensation, or the interaction of components to accomplish the desired goal even in the face of obstacles. Synergies have a number of additional features found in complex systems, or systems with numerous, nonlinearly interacting elements across multiple spatial and temporal scales. Complex systems offer tools for identifying some of the features of cognitive synergies. For example, 1/f scaling has been demonstrated in a range of cognitive tasks, supporting the notion that features common to both complex systems and synergies play a key role in cognitive functioning. 1/f scaling, or “pink noise,” can be used as an indicator of coordination or task interdependence, with “white noise” as an indicator of independence. Three experiments compared isolated and distributed cognition to determine which are appropriately characterized as cognitive systems composed of individual agents or as distributed among (and irreducible to the behaviors of) multiple agents. Each experiment tested for interdependent and emergent properties of cognitive performance during distributed temporal estimation (TE) tasks.
1/f scaling was present during solo and dyadic tasks, providing evi (open full item for complete abstract)
