<br>
I'm running an experiment using triggers from Eprime to a BrainVision
equipment. I need Eprime to send a trigger according to the position of target-words along the sentence e.g. at 0, 5, or 11 seconds
after the beginning of the sentence. I tried used the following script:<br>
<br>
WritePort &H378, c.GetAttrib("trigger") 'identifies the item’ <br>
sleep c.GetAttrib ("delay") 'identifies the position of the target-word after the beginning of the sentence’ <br>
c.SetAttrib "CheckResponseTime", Clock.Read<br>
<br>
I defined two attributes: (i) trigger, as a code to identify the trigger
according to each sentence, and (ii) delay, as the time after the
beginning of the sentence the trigger should be sent to BrainAmp. After
listening each sentence, the subject has to answer a yes-no question to
check understanding. The problem is that the BrainVision cannot register
the trigger synchronized with the delay attribute, but only with the
time the subject hits the answer button.<br>
<br>
Does anyone have a solution or an alternative script for my experiment?<br>
<br>
Thanks in advance</span></span></span></span></span>
