This conversation, while fascinating, has reached the point where (for me) it may as well be written in Akkadian, on small clay tablets.

I think the language used is Saccadean. That is what my eyes tell my brain, at least.
My reply to you is as a matter of fact written on a tablet. Hope it is legible to you, my hieroglyphics are often misinterpreted.

The Crow I usually enlist for writing my clay tablets in cunaeform has the weekend off. Also, I have not fired up the kiln so claybaking is not taking place today.

All kidding aside, this is a lot to digest but very interesting.

A remarkable discovery by Triesman and her colleagues is that the sub-conscious and parallel processing of certain elementary attributes is automatically reported to our conscious awareness only when a salient feature is present in a particular location and not present elsewhere.

One can ask whether this is a "remarkable discovery" or a careful scientific elaboration of something quite obvious, that must go back very far indeed on the evolutionary timeline, long before humans or human consciousness. (It is after all why camouflage also evolved.) And even whether the result is "reported to our conscious awareness", since our gaze tends to be directed there before we know why.

It is my understanding that, although it is intuitively obvious, and has been widely accepted for millennia, there is no scientific “proof” that the optimum shape for a wheel is round. (circular)

However, I may have missed it somewhere.
