New approach to eye training may significantly improve performance
...olunteers started with the noisy displays and then switched
to clear. Over five days, the volunteers made nearly 4,000 practice judgments in each condition, with accuracy measured every 180 trials. The researchers found that those who first trained on the clear displays approximately doubled their efficiency...
Smart plastics change shape with light
