So… does this imply that our perception is template-driven?

Perception is highly influenced by top down information as the brain models what it expects to see. It’s complex, but attention learned representations of the world have an enormous influence on perception.

  Perception Deception: Nova https://www.youtube.com/watch?v=HU6LfXNeQM4 https://www.youtube.com/watch?v=HU6LfXNeQM4 Your Brain - Who's in control: Nova https://www.youtube.com/watch?v=yQ6VOOd73MA https://www.youtube.com/watch?v=yQ6VOOd73MA Both of these videos are great resources on how much of what you experience of reality is made up or filled in by your brain at any given moment. I believe it's the Perception Deception episode that shows us how little of our vision is actual HD quality and that an external observer doing eye tracking on you can present a different reality to you than a 3rd party looking at the same object you are (on a screen at least, little bit harder in the real world).

    Which leads to foveated rendering which is nearly perfect on my Apple Vision Pro but if you quickly move your eyes up and down and side to side eventually the sensors lag and you see the blurriness. It’s a very clever use of our vision processing that you only need to render in full 4K what our very narrow foveated view can see. As long as your eye tracking and lag is lower than around 12ms ish.

  As someone who reads a great deal (both print and screen), many times I've glimpsed part of a written word, or even something that looks like a written word, and my brain has automatically generated a complete (and wrong) word. I catch it when a moment later I think "why would that word be there" and either I'll double-check and the word will turn back into whatever text fragment or letter-looking thing, or more rarely my memory of the pseudo-word will change.

  Nicely expressed. Thank you.
