The study looked at how cognitive abilities change as people age, focusing on executive function and perceptual speed. The researchers analyzed data from a group of elderly participants over an 11-year period. They found that decline in executive function was more noticeable in older age compared to perceptual speed. This supports the idea that cognitive aging affects more complex abilities like executive function, particularly in the frontal lobe of the brain.
