At IAPCT 2019 in Manchester my presentation was titled “Stalking perceptions in the wild”. I have expanded my presentation into a brief paper.
Bill Powers identified the different orders of perception in the perceptual hierarchy by introspection. In Behavior: The control of perception (B:CP), he summarizes the first five levels (Intensity, Sensation, Configuration, Transition, Sequence) in Chapter 12, “The brain’s model”. In that chapter he talks of “Event or Sequence” perceptions, and later he recognized that an Event is brief, well-practiced, and generally not interruptable, and there for that they must be distinct, making six levels.
Beginning in Chapter 13 he was passing "from the world of ‘physical reality’ to the world of ‘subjective reality’, as he put it, and the next level, Relationships, is “a transitional one, for certain of its aspects seem easy to conceive of as aspects of the solid, real, lower-order world, while other aspects strike us as more as conceptual in nature.”
It is when he posited that the next higher level was one of Programs that, in my view, he was misled by prevalent and well established presuppositions: the assumption that logic describes our thought processes (rather than being a discipline that may be imposed on them), the computer as metaphor, and conceiving of words as symbols. It seems to have been partly because of these assumptions that he broached the idea of Category perceptions in that section of Chapter 13, which later, unfortunately, became thought of as a distinct level of the hierarchy.
Bill repeatedly cautioned us against taking his proposed identification of levels in the hierarchy as dogma. The relative hierarchical order of these different kinds of perception was a matter of change, reconsideration, and some uncertainty during the 1990s and later. I think it is important for us to go back to basics, and examine in a naturalistic way what is going on with Sequence perceptions as control at a higher level selects, interconnects, interrupts, and otherwise manipulates and uses them for its own purposes. While we’re at it, what perceptions are served by controlling Relationship perceptions? By paying attention to Sequence and Relationship perceptions are used, we can infer characteristics of the systems that are using those perceptions as their means of control.
I have attempted a start at this in the paper, “Stalking perceptions in the wild.”
