[FRIAM] mental imagery

It's kinda weird to suggest this "does not calculate trajectories or predict where the ball will land". Holding Ψ constant is a calculation and at least an "indirect" prediction, right? And the physiological correlate to the calculation is the "continuously adjusting their movement".

Just because our "mental image" (aka calculation) isn't the one some tran-scient Daemon [⛧] might use doesn't mean we don't use *any* "mental image" (aka calculation). It seems a bit xenophobic! >8^D  https://furm.org/misc/against-mind-blindness-levin.pdf

⛤ Obviously, I'm trying to find a word indicating a bounded scope of "science" or knowledge or percpetion or whatever, a scope somehow greater than a human but less than omnicience. I feel so stupid today.

Originally, I was going to double down on the gobbledygook with this paper:

Zeno and Anti-Zeno Dynamics at the Core of Conscious Agency: On the Teleodynamics of Meaning
https://philpapers.org/rec/RUDZAA?ref=mail

which I failed to read this morning because my intuition kept yelling about pseudo-profundity. I am at risk of being gulled into believing whatever nonsense my gaze happens on ... not a typical Monday, that's for sure.

>> In Gibsonian and Turvey ecological language: the fielder does not calculate trajectories or predict where the ball will land; instead, they visually couple their locomotion to optical information that specifies the event of interception. By continuously adjusting their movement to maintain a constant optical acceleration pattern (the Optical Acceleration Cancellation strategy), they exploit invariants in the optic flow—the affordance of catching emerges directly from perceiving how the optical variables change, not from internal computation or prediction.:

Even the 2 "objective" measures I'm aware of (pupil response and binocular rivalry) are intertwined with the body. I'm reminded of "motor imagery", where imagining some physical action causes similar patterns to performing that action, and so-called mirror neuron[al activation].

He'd *draw* graduate level concepts on the chalkboard before class, then really quickly run through all the jargon as if we understood whatever he was yappin' about. Then he'd callously erase the art and get on with what we were "supposed" to be learning. Dude was an artist. Full stop.
