Instructions

In this experiment, you will be presented with a string of letters followed by a mask.

1. At the beginning of each trial, you will see a fixation '+' which you should focus on. When you are ready to begin a trial, press the space bar.
2. Sometimes the letter string will be a word (like 'STOP') and sometimes it will be a non-word(like 'OSTP'). You will then be shown two letters; one will have been in the letter string, one will not have.
3. Your task is to indicate which letter you think was in the letter string. The letter string will be presented very briefly, but still attempt the experiment even if you aren’t consciously aware of the letters that have been presented. You may be surprised at how accurate your responses can still be! You will then begin your next trial.

You will complete 10 practice trials and 80 experimental trials. Click on the button to begin.
