I know my math skills have deteriorated over the years. I had to take a statistics class about 10 years ago, and it wasn't easy for me. In my 30s, it would have been a piece of cake, but in my 50s, it was tough.
As far as alerting, orienting, and executive inhibition...
- Alerting - I don't seem to process information like I used to. I can't take in a lot of information concurrently, which can be a bit unsettling when I'm driving. It also affects my decision making abilities when I don't have time to think about what I'm doing. That's one reason I like buying things online; it allows me to think about what I'm buying without distractions, and I can think about it for a while.
- Orienting - I guess I can quickly shift my attention to something effectively, but I don't know if I can do that more so than when I was younger. I used to be able to take in the big picture more effectively when I was younger.
- Executive inhibition - No way, dude. A good example is this evening when I was at the pharmacy section of the grocery store, looking for Tylenol for arthritis, and they had contemporary pop music blasting. I swear, I was so distracted by the "music" that I couldn't concentrate on what I was looking for. At one point, I even put my fingers in my ears to try to block it out. Of course, had they been playing classic rock, it wouldn't have been a problem. To me, contemporary music is like having a loud ringing in my ears.
So in my case, their study is total B.S. Maybe for others, it rings true.
