Since it came up last night, some more comments on "awareness."
Here are some simple examples of everyone's ability to keep track of multiple objects in space:
http://ruccs.rutgers...n/DemoPage.html They're set up as baselines, so most adults should be able to track the 4 objects fairly easily. Things obviously get harder as you try and track more objects, speed up the objects, add in distractions, etc.
Now if you keep your eyes fixed on the lower 1/4 of the screen and track the objects, you'll find that it's harder and things tend to fade in and out of your peripheral vision. That is every clicker in WoW. That is also every healer who stares at health bars in Grid, Healbot, etc. If you keep your eyes fixed in the middle of the screen, you can naturally see more and it's easier to keep track of the different objects. Stop looking at your bars, stop staring at health bars, look at the middle.
Every person has a limit for how many things they can keep track of at once, whether it's visual like the examples above, motor skills (patting your head and rubbing your stomach) or auditory/verbal (having a conversation and listening to the lyrics of your favorite song at the same time). WoW (and life) tosses you a lot of useless information that you don't need to function. The goal is to minimize the distractions so you can focus on the task at hand.
So once you can do your job (DPS, healing, tanking) without looking down at bars, you can focus on your toon and whether it is standing in fire or not - this should be the bare minimum if you want to be a decent raider. If you master that, you can look at what other people in the raid are doing - now you're back to the original tracking 4 dots experiment. You already have all the other crap you're doing in the bank, now you can just stare at the dots moving around and rage when a healer dies to a cat leap. Congratulations, you're a raid leader. (Note: It's natural to have a loss in personal performance as you try and pay attention to more and more things. My DPS suffers if I'm calling out rotations on Baleroc and making sure the next person is standing in the right place, that people with the debuff are clearing out, etc. But as long as you can maintain some general level of competence it's fine - you can worry about topping meters when the boss is on farm).
Back to the example I used last night - you don't always have to stare at the football. The average NFL play lasts 4 seconds. There are 22 men on the field. Plenty of individual and group interactions happening away from the ball. To me that's where the beauty and intricacies of the game lie. All those little squiggly lines that pop up when you play Madden actually mean something in the overall strategy:

Another example, don't just stare at the taillights in front of you when you're driving - look ahead a few cars and at the traffic signal. If the light is turning red, you don't have to wait for the car in front to slow down, just downshift and coast (unless you're a pussy who drives an automatic).
And finally, a presentation that goes over some of the technical stuff (not too bad jargon wise):
