Mental speed does not start to slow until people turn 60, four decades later than previously thought, a study has suggested.
Researchers say their analysis of more than a million people challenges previous assumptions that mental speed peaks at age 20.
As humans age, it takes longer to react to changes in the environment or stimuli.
This slowing of response time starts from the age of about 20, gradually continuing to slow as people age.
The new study found that although response times started to slow after 20, this could be because people make more cautious decisions and engage in processes not linked to decision-making at a slower rate, such as taking more time to press a computer key.
However, the mental process of making decisions does not start to slow down until age 60, after which it progressively declines.
Mischa von Krause of Heidelberg University in Germany and colleagues looked at data from more than one million people who took part in an online experiment that measured their reaction times to a mental task.
Participants had to categorise a selection of words and images that flashed up on a screen as belonging to one of two categories, for example good or bad, by pushing the correct key in response.
Despite a widespread belief in age-related slowdowns in mental speed, the findings highlight that, for much of life and during the span of a typical career, this is not likely to be the case.
“Our results indicate that response time slowing begins as early as age 20, but this slowing was attributable to increases in decision caution and to slower non-decisional processes, rather than to differences in mental speed,” said the researchers, writing in Nature Human Behaviour.
“Slowing of mental speed was observed only after approximately age 60.
“Our research thus challenges widespread beliefs about the relationship between age and mental speed.”

Conflict, drought, famine
Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.
Band Aid
Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.

Five ways to get fit like Craig David (we tried for seven but ran out of time)
Start the week as you mean to go on. So get your training on strong on a Monday.
Train hard, but don’t take it all so seriously that it gets to the point where you’re not having fun and enjoying your friends and your family and going out for nice meals and doing that stuff.
Think about what you’re training or eating a certain way for — don’t, for example, get a six-pack to impress somebody else or lose weight to conform to society’s norms. It’s all nonsense.
Get your priorities right.
And last but not least, you should always, always chill on Sundays.
