Self-organisation and attractors

On October 30, 2019

In this article, we will be focusing on two key concepts of ecological-dynamics: self-organisation, and the attractor landscape.

As we have shown previously, ecological-dynamics understands our bodies as complex systems with numerous interacting parts (or degrees of freedom). Self-organisation means that the parts of the system have a tendency to adjust and adapt to each other¹, creating patterns without the need for a hierarchical system of control, like the brain controlling every single part of our body. Order therefore is emergent, and does not require the micromanagement of all degrees of freedom.

The dynamical systems approach

In Theory

Dynamical systems theory is a branch of mathematics used to describe complex dynamical systems. These are systems with multiple parts that interact with each other and change over time. Examples can range from living things like a colony of ants to inorganic systems like Earth’s climate. Ecological-dynamics adds these mathematical insights to ecological psychology in order to understand how we control our movements, focusing on the interactions between the body and environment instead of reducing it to a top-down control from our brain. In this article, we will try to understand our bodies as complex dynamical systems, while not going into the details of the complex equations.
