Gerald Rivera60 said:That brings up the question of how we process abstract concepts.
The bulk of information we receive arrives via language. Someone speaks, and that audio hits the primary auditory cortex for basic sensory processing. From there, those tones are synthesized into meaningful phonemes and sent deeper into the brain, where the vocal sequence is translated into a series of connected concepts. It then integrates into an existing semantic network, accounting for context and everything else.
At this stage, the processing of raw percepts is lost. When I say "I need to buy bread," I am not working with mental images or simulating the act of purchasing; I am operating with concepts. Everything stays at a symbolic level. This allows us to handle massive amounts of data. In fact, if we had to operate using raw mental representations, we would be much slower. Instead, we swap them for concepts—using a semantic network to perform our mental data processing.
We only rely on mental imagery when we lack specific skills or when we are learning something new and need to visualize it.
In most cases, perception acts merely as a trigger for processes within semantic networks.
(We need more "hard" cognitive psychology topics on this subforum)
Heh... interesting theory.
The pathway for processing emotional information is different from other types of data. Ultimately, the cortical regions handling that processing are distinct.
Take prosopagnosia, for example. It’s a specific disorder caused by a lesion in a certain part of the cortex, resulting in an inability to recognize faces despite having perfectly intact perception of everything else. A person with prosopagnosia can see a nose, eyes, and individual facial features, but they cannot synthesize them into a cohesive whole. Otherwise, their perception remains normal, no matter the complexity. This proves we have a dedicated center in the brain for this task. Evolution likely favored individuals who were better at recognizing faces—and the expressions on them—as it improved survival and reproduction.
(But now we're drifting into evolutionary biology... that's a topic for another day. Still, it's fascinating how evolution, emotion, perception, semantic networks, language, and social context all intertwine. It reminds me of how a French historian might say there is no history of France, only the history of Europe, and no history of Europe, only the history of the world)
See, when I say "I need to grab some bread," I'm definitely working with mental imagery.
Those three little words act like a trigger that pulls up every single image my brain has stored.
I can already see the whole loaf—maybe a half, maybe a chunk—and whether it’s soft or crusty.
I can almost smell the fresh bread, picture the walk to the corner store, see the cashier's face,
think about the cash I need to carry, what I'm having with it, and a million other tiny details.
Only after my brain processes all that does it set the stage for me to actually leave.
It kind of explains that "automatic no" thing too.
When someone asks you for a favor, your first instinct is often just "NO,"
mostly because your brain just needs enough time to run through all those generated images.
So, I'd argue abstract concepts are just triggers to find
and link together everything we've already perceived.
If I said "I need to buy brenk," then you're just messing with words that mean nothing
until your brain scans its memory to find something familiar.
That's basically the brain's job—filtering through info—and you can't really stop it from happening consciously.
