Ah but what if it's a cascading effect?
Snowball starts rolling from the visual cortex, the dominoes
fall and by the time it reaches conscious processing, we're
already 1/2 way there tongue emoticon
Anyway, the issue of Attention is a very important one with
regards to decision-making. We ignore nearly everything around
us nearly all of the time (which is something that was always a
struggle for me - I suspect I'm in the autistic spectrum
somewhere) ... and I suspect we'll find decision-making
happening all throughout our bodies.
