Visual processes 'critical for sharp mind'

[Northerner]

Scientists say they have uncovered a basic process that may help explain why some people's thinking skills decline with age.

Research indicates as individuals begin to have difficulties interpreting simple images, their overall intelligence falls too.

Psychologists suggest this ability to glean information at a glance may play a critical role in how we deal with more complex tasks.

The study appears in Current Biology.

Psychologists from the University of Edinburgh studied 600 healthy 70-year-olds for six years.

Interesting but I find I am less inclined to be bothered putting in the effort for random puzzles, it's not that I can't do it it's just that I don't want to. Did they test for that? or was everyone trying really hard.
