Millisecond Forums

Hi everyone,

I'm a first time inquisit user and have managed to write a working forced choice learning task that I intend to collect with ERP data. Unfortunately not a ll the markers that I have programmed via the <port> function are appearing in the continuous EEG recording. It is recording markers for the feedback presentations and the first stimulus presentation (set at 500 ms in trials) but not the second (set at 1300 ms in trials). I would like the second stimulus to be recorded too. We had a few eyes look at it in our lab today and couldnt work it out, so i appreciate any help or suggestions you may have.

Thanks alot everyone. see script below

insrtuctions and page breaks

<page intro>^^^^          Please read these instructions carefully.
^^^^    If you have any questions, feel free to ask the experimenter.
^^^^         PRESS "SPACE" TO BEGIN READING.
</page> <page break>^^What follows is a learning task in which you will learn to make the correct response on each trial.
^^At the beginning of each trial a cross will appear to warn you that the trial is about to start.
^^You will then be shown two pictures (one at a time) and finally will be asked to choose between two symbols ( "O"  or  "*" ).
^^If you choose the correct symbol you will GAIN points but if you choose the incorrect symbol
you will LOSE points.
^^^^            PRESS "SPACE" TO CONTINUE
</page>

<page break1>^^However, there's more to this task than that, as the different symbols have different values.
^^IF YOU CORRECTLY PREDICT THE  "*"  SYMBOL YOU WILL GAIN 50 POINTS.
^^IF YOU CORRECTLY PREDICT THE  "O"  SYMBOL YOU WILL GAIN 1 POINT.
^^^But if you predict the incorrect symbol you will lose points. IF YOU INCORRECTLY PREDICT THE  "*"  SYMBOL YOU WILL LOSE 50 POINTS.
IF YOU INCORRECTLY PREDICT THE  "O"  SYMBOL YOU WILL LOSE 1 POINT.
^^   So, in this game THE  "*"  IS WORTH MORE THAN THE  "O".
^^^           PRESS "SPACE" TO CONTINUE
</page>

<page break2>^^But how will you know which symbol to select on which trial?
^^^THE PICTURES THAT APPEAR DURING EACH TRIAL WILL ALLOW YOU TO ACCURATELY PREDICT WHAT THE CORRECT SYMBOL IS FOR THAT TRIAL.
^^^Therefore you will need to LEARN which pictures will allow you to predict
the correct symbol.
^^Once you know that, the task will become easy because the pictures that appear on a given trial will allow to predict which response you need to make in order to gain points.
^^^           PRESS "SPACE" TO CONTINUE
</page>

<page break3>^^Remember... the ORDER in which the pictures appear HAS NO INFLUENCE ON THE CORRECT RESPONSE FOR THAT TRIAL.
^^The only thing to learn in this task is which pictures are associated with which symbol.
^^^And the ONLY way to learn this is by TRIAL AND ERROR.
^^^^^           PRESS "SPACE" TO CONTINUE
</page>

<page break4>^^Every so often you will be given a break. Use this time to rest your eyes and continue when you are ready to keep going.
^^^The next time you press "SPACE" the task will begin.
^^Dont forget, in this game you can win and lose points, the aim is to learn which pictures go with which symbols and the "*" symbol is worth more than
the "O" symbol.
^^When the game starts, use the YELLOW keys to indicate your choice.
^^^^         PRESS "SPACE" TO BEGIN THE GAME
</page>

<page break5>
^^^^^^   Take a break. Give your eyes a rest and when you are ready...
^^^^            PRESS "SPACE" TO CONTINUE
</page>

<page break6> 
^^^^^^               Have another rest.
^^^^               This will be your last block.
^^^^            PRESS "SPACE" TO CONTINUE
</page>

<page end> 
^^^^^^^             THAT'S THE TASK COMPLETED!
^^^^               Thank you for participating.
