Cognitive Ability Peaks At 22 And Declines After - Maybe
A study by psychologists at the University of Virginia found that cognitive performance peaked at age 22, after which a cognitive decline became detectable at age 27. The study's lead researcher, however, warns that these results should be interpreted carefully because there was a lot of variation among individuals. As well, things like a decline in memory may be offset by improved general knowledge which tends to increase at least until people are into their 60s. The long-term study hopes to identify how cognition patterns change over a person's lifetime.
