Re: [agi] Clues to the Mind: What do you think is the reason for selective attention

[David Jones]

I found proof of my interpretation in the following paper also. It concludes
that we can only keep track of 3 or 4 objects in detail at a time.(something
like that)

http://www.pni.princeton.edu/conte/pdfs/project2/Proj2Pub8anne.pdf

It says:
"For explicit visual working memory, object tokens are stored in a limited
capacity, vulnerable store that maintains the bindings of features for just
2 to 4 objects.
Attention is required to sustain the memories."

[deepakjnath]

Thanks Dave, its very interesting. This gives us more clues in to how the
brain compresses and uses the relevant information while neglecting the
irrelevant information. But as Anast has demonstrated, the brain does need
priming inorder to decide what is relevant and irrelevant. :)

Cheers,
Deepak

Re: [agi] Clues to the Mind: What do you think is the reason for selective attention

[David Jones]

I also wanted to say that it is agi related because this may be the way that
the brain deals with ambiguity in the real world. It ignores many things if
it can use expectations to constrain possibilities. It is an important way
in which the brain tracks objects and identifies them without analyzing all
of an objects features before matching over the whole image.

This week I finally found a cool body of research that I previously had no

missed it the first time. It has to do with human perception, object files,
how we keep track of object, individuate them, match them (the
correspondence problem), etc.

And I found the perfect article just now for you Deepak:
http://www.duke.edu/~mitroff/papers/SimonsMitroff_01.pdf

This article mentions why the brain does not notice things. And I just
realized as I was reading it why we don't see the gorilla or other
unexpected changes. The reason is this:
We have a limited amount of processing power that we can apply to visual
tracking and analysis. So, in attention demanding situations such as these,
we assign our processing resources to only track the things we are
interested in. In fact, we probably do this all the time, but it is only
when we need a lot of attention to be applied to a few objects do we notice
that we don't see some unexpected events.

So, our brain knows where to expect the ball next and our visual processing
is very busy tracking the ball and then seeing who is throwing it. As a
result, it is unable to also process the movement of other objects. If the
unexpected event is drastic enough, it will get our attention. But since
some of the people are in black, our brain probably thinks it is just a
person in black and doesn't consider it an event that is worthy of
interrupting our intense tracking.

Actually Deepak, this is AGI related.

This week I finally found a cool body of research that I previously had no
knowledge of. This research area is in psychology, which is probably why I
missed it the first time. It has to do with human perception, object files,
how we keep track of object, individuate them, match them (the

May I flag this as AGI irrelevant? The brain at a non-AGI task is not
that interesting for AGI, me thinks.  Plus, we have loads of
specialist opinion on these things. Having just missed the gorilla
myself, I would be curious to see the video´s effectiveness with
different screen sizes and different prompts though. How about the
prompt "which of these players is the most intelligent"!

Can anyone suggest why our brains exhibit this phenomenon?
