[Xmca-l] Re: Bateson on thinking relatively

[WEBSTER, DAVID S.]

The perception-action cycle has been a topic of debate in the Gibsonian literature since the early -mid  1980s i.e. just after Gibson died in 1979

I’m struck by the similarity between Bateson’s description and the notion floating around in neuroscience of a “perception-action cycle,” in which brain, body, and environment are each components in a circular process.

The perception-action cycle is a circular cybernetic flow of information processing between the organism and its environment in a sequence of goal-directed actions. An action of the organism causes an environmental change that will be processed by sensory systems, which will produce signals to inform the next action, and so on. The perception-action cycle is of prime importance for the adaptive success of a temporally extended gestalt of behavior, where each action is contingent on the effects of the previous one. The perception-action cycle operates at all levels of the central nervous system. Simple, automatic, and well rehearsed behaviors engage only the lower levels of the perception-action cycle, whereas, for sensorimotor integration, the cycle runs through the spinal cord and subcortical structures.

To the extent that deliberate, reflexive planning becomes part of the cycle on its highest levels, the sense of being the initiator of action can be hard to resist. But it’s just the walnut on the cupcake.

Here’s a diagram, though it’ll be probably be removed, so here’s the link too…
