@rjwatt42.bsky.social Greetings. Across your research into spatial cognition, did you examine how Coulomb’s law might be implicated in the cognitive construction?

Thank goodness we don’t have any discrete scalar measurement biological capabilities, then! WRGB has the added accidental upside of taking poorly formed pictures and creating a less busted up presentation out of them.

Indeed. And the decoding of air waves to sound is at least as complex as pictorial depiction decoding of stimuli into forms. It just drives me to distraction that folks have this myth of “idealized pictorial depiction is a simulacrum of the stimuli” forced upon them, reinforced by the seduction.

“Filmic”, or more accurately, the unique relationship between total energy within a given region and the interrelationship of chrominance to luminance, is akin to a grammatical writing tool. Without it, we have a higher cognitive tax on the interpretation of the forms within a pictorial depiction.

https://bsky.app/profile/troy-s.mastodon.art.ap.brid.gy @troy-s.bsky.social · 15/01/2025
Bingo. And the deeper problem is that there is the incredible cognitive mechanisms that decompose and segment stimuli into forms that no one realizes without paying close attention. The “essence” of the all-too-abused “filmic” term is what we all ought to realize as *a cognitive text*.

We are *so* brain wormed by the legitimated orthodoxy that no one has stopped to ask what we are trying to do. There’s also a founding myth prevalent; that a pictorial depiction is idealized when the stimuli is presented as it was in front of the camera. This brain worm needs to stop.

Expected. It doesn’t exist as a construct beyond a few folks who have thought this through. I’m sort of wrestling with a post on this subject, hence why I wanted to borrow the quotation. Pictorial depiction is something folks need to focus on. Not the bullshit of “scene” and “display” rubbish.

Someone gets it. In fact, calling the picture formation a “tone mapper” or “display rendering transform” is obfuscating nonsense. It is quite literally the algorithm that crafts the pictorial depiction. I’ll be long gone before folks abandon Giorgianni-Kodak’s bullshit ideology.

This is key because several logical questions flow from this fundamental, biological entry point. 1. If the signal is a *gradient* relation, it requires multiple samples across the spatial frustum. 2. If the signal is a *gradient* strength signal, why does what we think we “see” seem different?
000
https://bsky.app/profile/troy-s.mastodon.art.ap.brid.gy @troy-s.bsky.social · 23/12/2024
Why is this crucial to deconstruct as a myth? Because the “optic signal” is not a discrete scalar value of the spatial frustum. It’s in fact a complex overlapping of inhibitory signals; it’s a *gradient* signal. *There is no “picture”* as we think of a moving picture “frame”.

A key part of this myth is the *absolutely false* belief that the cones “measure” the electromagnetic radiation they are sensitive to. This is *outright false*. In fact, we can attribute so much of our misunderstanding around colour cognition to this origin story myth.

https://bsky.app/profile/troy-s.mastodon.art.ap.brid.gy @troy-s.bsky.social · 23/12/2024
A key part to dismantling the notion around stimuli - the electromagnetic radiation - as *colour*, is to focus on a multi-pronged assault on the myths we’ve been sold. The first, pervasive myth, is the “Eye as a Camera” myth. Gilchrist has called this the “Eye as Photometer” myth.

(The stimuli in the interior “rectangle” region is identical in both cases, yet most folks have a higher than average probability of *not* cognizing a “hue drift” in the second example.)

How can we prove this? Quite simply; design a demonstration that is reasoned and logical that pushes back against this “stimuli as colour” nonsense myth. Ok. Enough for BlueSky. Anyone interested in the mechanisms can be pointed in the right direction by way of reliable papers.

https://bsky.app/profile/troy-s.mastodon.art.ap.brid.gy @troy-s.bsky.social · 23/12/2024
the “middle” region of the “rectangle” has a probability of being cognized as “drifting to a mauve-purple”? Now the CAM / UCS foolishness would try to “unbend” that. But of course that’s a bogus approach. Why? Because the effect is: 1. Cognitive. 2. Emergent from the articulation of the stimuli.
