Re: [agi] Clues to the Mind: What do you think is the reason for selective attention
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. Dave On Sun, Jul 25, 2010 at 1:00 AM, deepakjnath deepakjn...@gmail.com wrote: Thanks Dave, its very interesting.

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.

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! --- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244id_secret=8660244-6e7fb59c Powered by Listbox: http://www.listbox.com
