stick some triplets in there and you’ve already bypassed 250ms quite easily.

very well put together and it’s true that, for _pragmatic_ reasons, yes we live in a space that can be considered the present, but still, there are ways to break it down that can get quite finely grained.

Some of the work being done in the past with psychology and human perception had very long time-scales in comparison to conscious awareness.

In my opinion, time scales of 250ms or greater are too long when speaking of “the present” as that’s a 1/4 second. It’s very easy to be aware of many things going on within that 1/4 of a second.

Not that it isn’t useful but it’s beyond automatic at that point and it’s more in the “stereotypical reactions” that are easy enough to overcome with simple self-awareness. [introspection].

Music is an easy example. 250ms is a long time in music. At 120bpm, that’s 2 beats per second. 500ms each beat. 250ms up beat, 250ms down beat

There’s certainly a bottom limit to awareness – I have the numbers somewhere, but I suspect you are correct about the optic tectum. If it’s the same area of the brain I’m thinking of, it’s related to the system that pattern matches outlines quickly and snaps the amygdala and reaction systems into place before we can say, “WHAT JUST HAPPENED HERE?”

That’s something we can be aware of nearly real-time – that is, the difference in time between reaction and recognition.

Then it gets trickier – some things are nearly real-time. For example, blindsight is something barely studied, but it works. Drop a plate that you can’t see, and you can catch it without looking or before you’re even aware that you dropped it.

I suspect it’s related to our internal mental map encompassing our body and whatever tools we have along with it [like extending our body to the size of the car we drive, or the hammer we’re holding… or the plate we just dropped]… but I don’t know enough to say, although I suspect when they speak of blindsight it’s more to do with the blind being able to catch a ball thrown at them even without optic nerves, so long as that “blue light sensor” is intact… the one that helps regulate sleep/wake cycles.

In any case, it’s an interesting period of time.. this 250ms and below.
