When older people can no longer remember names at a cocktail party, they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong.
Instead, the research finds, the aging brain is simply taking in more data and trying to sift through a clutter of information, often to its long-term benefit.
The studies are analyzed in a new edition of a neurology book, “Progress in Brain Research.”
Some brains do deteriorate with age. Alzheimer’s disease, for example, strikes 13 percent of Americans 65 and older. But for most aging adults, the authors say, much of what occurs is a gradually widening focus of attention that makes it more difficult to latch onto just one fact, like a name or a telephone number. Although that can be frustrating, it is often useful.
“It may be that distractibility is not, in fact, a bad thing,” said Shelley H. Carson, a psychology researcher at Harvard whose work was cited in the book. “It may increase the amount of information available to the conscious mind.”
For example, in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases, adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean, older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling over the extra information, but are taking it in and processing it.
When both groups were later asked questions for which the out-of-place words might be answers, the older adults responded much better than the students.
“For the young people, it’s as if the distraction never happened,”...

Are you still working with refugees?
Ohhh...no sugar for me!
Thanks for the ping to this thread the day after I learned I’m going to be a grandmother.
It’s all in the timing. ;’) I for one turned 50 yesterday.
I usually just fake a heart attack when this happens :-)
