      Motion perception improves with age

      Older observers outstrip youngsters at some visual tasks

      As people grow older, their vision can actually get better in
      some ways, according to a Canadian study. The findings suggest
      that neurological changes could help the elderly to spot small
      motions in otherwise uniform scenes.

      Part of visual processing in the human brain involves cells that
      suppress each other's activity. This allows the mind to focus on
      a scene's important features while ignoring trivial regions. But
      as people age, these inhibitory interactions seem to weaken.

      To explore the effects of this change, researchers tested people
      between 18 and 31 years old, and others aged 60 and above.
      Subjects viewed a computer screen showing moving, vertical
      black-and-white stripes. They then had to decide in which
      direction the bands were travelling.
