it sounds like all you may really need is an If... Then statement.<br><br>'this is what you'll need in your trial procedure time-line:<br>Label1<br>fixation<br>A<br>mask<br>A'<br>Inline1:<br><i>If A'.ACC = 0 Then Goto Label1</i><br>
'this If... Then statement will cause the script to return to the beginning of the trial if the incorrect response is given (A'.RESP = 0)<br><br><div class="gmail_quote">On Jan 28, 2008 11:31 AM, Pedro Margalhos <<a href="mailto:margalhos@gmail.com">margalhos@gmail.com</a>> wrote:<br>

<div>Hi,</div>
<div> </div>
<div>I'm trying to set an experiment with e-prime to run a flicker paradigm. Therefore, i need do use a Do ... Loop Statement (more specifically a Do ... Loop Until condition). This because i need to have the stimulus repeated until the condition/answer is True.</div>
<div>The experiment consists in presenting a fixation cross, a picture (A), a mask, a picture (A'), a mask, and then have the participant to signal if there were any differences between both images presented. If there is no answer or a wrong (False) from the participant the set must be repeated.</div>
<div> </div>
<div>Thanks in advance,</div><span>
