I was reading for exams when I came across "The Theory of Information Pickup and Its Consequences," Ch. 14 in James Gibson's The Ecological Approach to Visual Perception. Gibson writes about ecological optics; a version of his theory of affordances appears in ch. 8. He's a small piece of what he writes about information pickup:
The act of picking up information, moreover, is a continuous act, an activity that is ceaseless and unbroken. The sea of energy in which we live flows and changes without sharp breaks. Even the tiny fraction of this energy that affects the receptors in the eyes, ear, nose, mouth, and skin is a flux, not a sequence. The exploring, orienting, and adjusting of organs sink to a minimum during sleep but do not stop dead. Hence, perceiving is a stream, and William James' description of the stream of consciousness (1890, Ch. 9), applies to it. Discrete percepts, like discrete ideas, are "as mythical as the Jack of Spades." (240)
What I find interesting is how the idea of constant information pickup helps us move toward more nuanced understandings of attention and attention structures (more like Linda Stone's "continuous partial attention" than a reductive two-type alternative: focus and digression). Much in this always-on "sea of energy" will be noise. But if we accept the persistence of "exploring, orienting, and adjusting," even during sleep, then the polar extremes of focus and digression have a whole lot of messiness and richness going on between them.
So it is noted. And tossed into the rock polisher, set to agitate until smooth against some other ideas about pickup, collecting: Katamari Damacy, Benjamin's unpacked library, Sirc's box-logic, database v. narrative, filtering, aggregation, overload, and so on.Posted by Derek Mueller at October 17, 2006 11:20 PM to Reading Notes
