A study Published in the Journal of Experimental Psychology: General found that blind research participants did not conceive of the past as being behind them and the future in front, as most sighted participants did.
To test this phenomenon, Italian researchers recruited 17 blind people, all of whom had lost their sight before their second birthday and had no visual memories, and 17 sighted people (who wore blindfolds) to take part in the experiment. Each had to categorize words that referred to the past or the future by pressing keys on a computer keyboard. In one test, they had to press the key in the forward position whenever they heard a word related to the future, and the key behind their resting position if it related to the past. In the second test, the two were reversed, so the forward key represented the past and the one behind represented the future.
