| summary | The challenge of temporal coordination lies in an organism’s ability to flexibly respond to changing events in a sometimes unpredictable environment. In this talk, I will discuss two general ways of explaining temporal coordination. First, there are model-based explanations according to which organisms coordinate with events through prediction from internal models, usually built into the central nervous system (CNS). The major shortcoming of these explanations is that prediction can only be as good as the models supporting it. Second, there have been recent attempts to envision a formally stronger foundation for temporal coordination, that is, one without internal models. Investigations of temporal coordination under conditions of unpredictability have shown that behavior may be structured not by an internal model local to the CNS but by interactions distributed across many different temporal and spatial scales of the organism and its environment. I present a cascade-driven alternative to prediction-based temporal coordination in which behavior is grounded in the multiplicative, multifractal structure of fluctuations. |
