<div>Hi All,</div>
<div> </div>
<div>I was wondering if someone could offer some advice with an eprime experiment that we are currently trying to set up. </div>

<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt">It's a face recognition experiment. During the learning phase participants will view 4 different groups of faces and with each group a different sound file will be played. During the test phase is where the problem arises. Participants are required to respond to ten faces while a particular sound track plays in the background. Participants can take as long as they like to respond so there is no time limit. However, once a participant has responded to all 10 images we need the sound track that is currently playing to terminate and a new sound track to begin for the second set of faces that will be shown.<span style="mso-spacerun: yes"> </span>However, this is where our problem arises, instead of the sound track finishing it simply plays over the new track. Any advice on how to terminate the first track before the second track starts? We have four separate trails in the recognition (test) phase each with a different track playing.</p>

<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt">We would really appreciate any advice</p>
<p class="MsoNormal" style="MARGIN: 0cm 0cm 10pt">Best wishes</p>
