Paragraph 2
The
used data on 1.1 million people, aged
10 and 80. The results showed that
processing speed remained
until the age of 60, but did start to decline after. The
said mental processing speed increased in people's 20s and remained
until 60. Dr von Krause said: "Until older
, the speed of information processing...
changed." He said older people taking
to make decisions may be because they are more cautious, less impulsive and less reckless. The study could cast
on diseases such as Alzheimer's.
