Coherence, Complexity and Creativity: the Dynamics of Decision Making

  • Fortunato Tito Arecchi
Part of the New Economic Windows book series (NEW)


Coherence is a long range order (either in space or time) which stimulates our curiosity and drives the scientific investigation. To build non-trivial correlations, a system must be away from thermal equilibrium; this implies entering a nonlinear dynamical regime, where coherence is just one aspect. The coupling of many partners leads to a multiplicity of equilibrium states, the number of which increases exponentially with the number of partners; we call complexity such a situation. Complete exploration of complexity would require a very large amount of time. On the contrary, in cognitive tasks, one reaches a decision within a short time. Indeed, any conscious perception requires a few hundred milliseconds. It is characterized by a collective neuron synchronization. However, the loss of information in the chaotic spike train of a single neuron takes a few msec; thus perception implies a control of chaos, whereby the information survives for a time sufficient to elicit a decision.
