Hi Micah, <br><br>I am sorry for joining this thread so late. I've been working on a similar situation and was wondering if you'd mind sharing what you've developed? Attached, are a couple of files I've been working with including, and inline VAS.vbs script, and some e-prime protocols that use it. The last includes IFIS calls. <br>
I am curious to know your thoughts on the attached files and what you've come up with.<br><br>Cheers,<br>Jason<br><br><br><br><div class="gmail_quote">On Thu, Jul 21, 2011 at 2:25 PM, Micah <span dir="ltr"><<a href="mailto:ucfmicah@gmail.com">ucfmicah@gmail.com</a>></span> wrote:<br>

from the scale stimulus. So now it works perfectly; it times out after<br>
6 seconds, which makes the "ISI" 0 duration, or it waits for 6-<br>
duration. So the scale can never take longer than 6 seconds, making a<br>
nice neat paradigm. I've also got it logging non-responses (in case<br>
the participant falls asleep) although have not yet come up with a<br>
solution for "confirmed" responses. Is there a wildcard variable in e-<br>
basic? If so I could do a check like, if stimulus.RESP = *3* then<br>
confirmed =1. Otherwise I may have to write a post-scan matlab script<br>
to search for any responses not containing "3", which is a blah<br>
solution.<br>
<br>
Tak,<br>
