instruct {Welcome.  In this experiment, you'll be reading some sentences on the computer screen.  You will first see 1 or 2 rows of dashes like this: 

------------------------------------------------------------
------------------------------------

These dashes are covering the words in the sentence.  When you press the space bar, the first word will appear.  With every press of the space bar, a new word will appear and the last word will become dashes again.

You should try to read as naturally as possible, making sure that you understand what you read.

When you finish reading the last word, press the space bar again.  The dashes will go away and you will see a question about the sentence you just read. To answer the question, press the "F" key for YES or the "J" key for NO.  You will be reminded which key is yes and which is no.  Try to answer as quickly and accurately as possible.

If you are unsure of the answer (or if you think that both answers are right), try to pick the better answer.

To be able to read and answer quickly, you should keep your fingers resting on the space bar and the "F" and "J" keys, so that you don't have to look down at the keys to answer. You can use whichever hand is most comfortable for you to press the keys, or use both hands if you like.}

instruct {You can take breaks as you need them, but please try to do so before you've started reading a new item, when the screen just shows dashes.

That's all there is to it.  Just to review, this is how the experiment goes:

1. Some dashes will appear on the screen and you must press the space bar to see each new word of the sentence. 

2. Read at a natural rate, comprehending what you read.  Don't read out loud unless that's the way you normally read.

3. You'll see a question about the sentence and should answer by pressing the "F" key for YES or the "J" key for NO.  

4. After the question, the computer will automatically go on to the next sentence.

When the experiment is over, a screen will appear telling you to stop.  At that point, you should let the experimenter know you are finished.

If you have any questions about the procedure, ask the experimenter now.
