Epiphany - attention vs. inhibition
Apr. 18th, 2009 06:11 pmIn my Research Methods class, we had to break up in small groups and run a research project, write up the paper and make a poster presentation. Our project was on attention. Attention is a process that include arousal and vigilance. When we are looking for something, we are in a state of arousal or anxiety -- when we find it there's a sense of relief. Vigilance is what keeps us looking until we either find what we're looking for or confirm that it is not present.
When we are searching for something in a field of distracters, we must hold attention for the thing which we are looking for, and at the same time, inhibit our notice of the distracters. The action of inhibition is not simply not-attention, it is something unique from attention, in the way that blue is not not-red, it is blue.
I gave my presentation last week Societal implications of the heritability of conduct disorder and I got an epiphany about attention and inhibition -- there have been some studies about ADHD vs. impulse, attention and inhibition. I think that only one study has been published so far, but it said something about inattention in ADHD being caused by impulsivity, not inattention. It didn't make sense to me at the time, and then, *boom* : It isn't that ADHD folks can't pay attention. It's that they can't inhibit. They are paying attention to everything. That's why speed works for them -- it helps them process the information of all that stuff that they are forced to pay attention to, because they can't inhibit the unnecessary information.
Cool, huh?
The funny thing is, I got to work and googled it up and, yep, that is just what the guys in lab coats are looking at -- deficiencies in response inhibition. Now I want to write a layman's article about it, but I'm wondering if it's old news and I'm just behind the curve. Anybody hear about this stuff?

You seem to be saying that his ability to perceive threats and targets from a group of enemies is actually enhanced by his condition.
One statistic I would like to see: how many returning war vets diagnosed with PTSD have ADHD? Based on what you've told us, I wonder if ADHD combat soldiers would be more resistant to PTSD?
