Is it possible to have dilated perception? (processing sensory info so fast that everything else seems slow)?

I think it has less to do with processing sensory info so fast and more to do with "ignoring" other irrelavant outside sensory info, so you can focus more on the sensory info that matters. This phenomenon is possible and some of the best of the best in their fields talk about it, usually having to do with physical activities. Take Michael Jordan, he calls it being in the zone, but the meaning is the same.

Well alot of head-injury/coma cases have had a processing sensory disorder, usually only temporarily while the brain is reconnecting with its connections. But it is not known if everything around them is slow b/c of that. It would make for a great thesis paper... I know this from syc class.

If your talking about the x-box game Bloodrayne while in Blood-rage mode. Gesh get real on here. I googled dilated perception

.....Think of the back part of the brain as the perceptual area and the front part of the brain as the conceptual area. When we focus on conceptual thoughts (understanding, evaluating, comparing, planning, organizing, etc.) we are not focusing on perceptions. And when we aren't focusing on perceptions, we aren't consciously aware of them...they are kind of in the background. When we aren't focusing on our external world, we aren't conscious of the passage of time. Time seems to go by amazingly fast.

So, you're right. If you focus intensely on the details of the world around you, as long as you sustain that focus, time will seem to go by slowly. A common example is watching the microwave timer while waiting for the popcorn to cook (2 min, 11 seconds on my microwave). Focusing on each second makes the passage of time seem very slow. But if you get lost in your thoughts, the popcorn seems to cook in no time at all.
