Many of us do not look, feel or act our age. Sooner or later, of course, time tends to catch up. Some abilities that we’ve had in our younger versions are no longer the same. Yet there are other ways in which we are sharper and smarter than we used to be. What researchers found out is that different mental skills peak at different times of a person’s life.

A 2015 study by MIT’s Joshua Hartshorne and Laura Germine from Harvard determined when exactly various kinds of cognitive performances were the strongest. Their research involved several experiments, with much data coming from two websites they set up that featured cognitive tests. These sites generated data from almost 3 million people in a few years.

One test the scientists ran involved 2,450 Americans from diverse backgrounds and locations, performing 15 tasks that ranged from math to vocabulary quizzes to picture completion.

What the results showed is that while the majority of mental power skills like memory, retelling stories and pattern recognition peaked from late teens into the 20s, a few notable ones got better with time and reached full potency by the 50s. These included vocabulary, math, general knowledge and comprehension (which was a test of how well participants could explain certain concepts). Such skills come from accumulated knowledge which benefits from a lifetime of experience.

Vocabulary, in fact, peaked even later, in the late 60s to early 70s. So now you know why grandpa is so good at crosswords.

Is there one age when all of your mental powers are at their maximum? The researchers don’t think so. 

“At any given age, you’re getting better at some things, you’re getting worse at some other things, and you’re at a plateau at some other things. There’s probably not one age at which you’re peak on most things, much less all of them,” said Joshua Hartshorne.

A 2014 study by Canadian researchers from Simon Fraser University provided another look at the question. They analyzed data from 3,305 players of the game “Starcraft II” between the ages of 16 to 44. 

What they found is that younger players had significant advantages in certain tasks. For example, a 24-year-old would be 150 millisecond faster than a player of the same caliber who is 39. In general, the researchers found 24 to be a key age, after which player abilities slowly declined, losing about 15% of the speed every 15 years. 

Older players did perform better in some aspects, making up for the slower brain processing by using simpler strategies and being more efficient. They were, in other words, wiser.
