<p>Thank you very much for your answer, Michiel! </p>
<p>I use E-Prime 2 and the method that you mention it's the same that I thought. <br>
I don't know Mat-Lab and neither my professor.</p>
<p>If someone else have other ideas I will glad to read it!</p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">However, you can still do what you want by using the soundcapture, to save the wave file for each trial (try to save the sound as a trial number or some such so that you know what condition it was in), and then get the reaction time from that. The hard way to do that would be to use any audio editor (I like cool edit, but audacity works), and see when a reaction is given. This is possible but will take a number of hours to work. If you know a little matlab, an alternative would be to do some signal processing and just detect for a threshold, which shouldn’t be too hard (find RT as time(dB > threshold)).<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">If you only have E-Prime 1, you could just record the whole experiment and have loud sounds as a synchrony marker.<u></u><u></u></span></p>
