I remember that and thought they came to the opposite conclusion. That the older you are the slower you count out a minute. I performed the experiment on my grandfather shortly after finding out and he counted out a minute in about 2.5 minutes. It'll take a while to go through the videos to reset my memory though.
I think that would make sense, because time seems to speed up as you get older, so if you think only a minute has passed when it was actually 2.5 minutes it would definitely feel like time had gone much more quickly than anticipated
Oh, I had some trouble wrapping my head around the idea. The older people count out slowly by as much as 40 seconds. They are inferring that the perceived time for the older folks is faster.
The article is wrong. From the book itself: "The older group, ranging in age between sixty and eighty, were off by forty seconds. Not far off, but if we were to extend the counting for, say, one hour, it would amount to more than thirteen minutes."
That's 30min + 13min.....they are counting slower....not finishing the task faster...
