                                

 Each trial starts with a short string of letters being flashed briefly 
 on the screen. This is followed almost at once by a SECOND 
 string of letters displayed at the same position as the first.
 
 Your task is to decide as quickly as you can whether this 
 SECOND string of letters forms a word or not. It will remain 
 on the screen until you respond. 

                 If it makes a WORD then press key `0'
                 If it is a NON-WORD then press `1'  
 
   PLEASE RESPOND AS QUICKLY AS POSSIBLE WITHIN THE LIMITS OF ACCURACY

  There will be a set of practice trials before moving on to the 
  experiment proper. During practice trials you will be given an
  audio feedback, that is every time you make an error you will
  hear a specific sound.

                To hear the sound now press 'L'
 
 
 Please note that during experimental trials no feedback will be given.
 
 
 
 
 
 REMEMBER:
 
 Please respond as fast as you can without making errors
 
 Press `0' for word and `1' for nonword
