Psychology in the News: Cognitive Functions Decline after Age 27

I still remember how freaked out I was when I turned 25. I figured my life was practically over and yet I had accomplished almost nothing. After all, John Keats died at 25 and he had written all that great poetry already! And Percy Bysshe Shelley, who mentored Keats, died at 28.

To test mental agility, the study participants had to solve puzzles, recall words and story details and spot patterns in letters and symbols.The same tests are already used by doctors to spot signs of dementia.

In nine out of 12 tests the average age at which the top performance was achieved was 22.

The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability.

Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.
