The research's central finding was that the nervous system uses past visual experiences to predict how blurred objects would look in sharp detail.

Researchers' approach presumed that people learn through countless eye movements over a lifetime to connect the coarse impressions of objects outside the fovea to the detailed visual impressions after the eye has moved to the object of interest.

The result of the experiments showed that the connection between a coarse and detailed visual impression occurred after just a few minutes. The coarse visual impressions became similar to the newly learnt detailed visual impressions.

Arvid Herwig said that people's perception depends in large measure on stored visual experiences in their memory and these experiences serve to predict the effect of future actions.

In other words: "We do not see the actual world, but our predictions."

The study is published in the scientific magazine Journal of Experimental Psychology: General.
