Hi David<br><br>I actually did put a CorrAnswer tribute in the Trial List. I dont think the second topic applies to me because the length of the trial does not change based on the response - i.e. I simply want to log the accuracy and speed of the response - the stimulus will stay on the screen even if they responded in the stimulus period (and not the wait period). <br><br>With regards to the trial list - is an empty cell = blank or does it have to have "" inside it? From the EPrime knowledge base it looks like it should be blank but from Anne-Wil's response it looks like it should have "" inside it. <br><br>Regards.<br><br>On Thursday, December 6, 2012 1:03:21 AM UTC+11, McFarlane, David wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Before going any further, please see

<br>> Hi All,
<br>> I posted a query on the e-prime discussion forum last week but
<br>> haven't had any replies yet. The main issue I am having in
<br>> programming a go/no-go task is that the acc column is incorrectly
<br>> returning a 0 when the answer is correct (but only for cases where
<br>> an individual should not be responding to the stimulus).
<br>>
<br>> I have posted the detail here:
<br>> <a href="https://www.pstnet.com/forum/Topic6489-23-1.aspx" target="_blank">https://www.pstnet.com/forum/<wbr>Topic6489-23-1.aspx</a>
<br>> <<a href="https://www.pstnet.com/forum/Topic6489-23-1.aspx" target="_blank">https://www.pstnet.com/forum/<wbr>Topic6489-23-1.aspx</a>>, but I will post
<br>> them here as well in case someone has an idea of how to correct
<br>> this. David - I know you are generally answered a lot of go/no-go
<br>> extended input type queries so I was hoping you might know.
<br>>
<br>> ===============
<br>>
<br>> The task is fairly simple - an either emotive (i.e. happy, sad) or
<br>> neutral word will appear on the screen for 300 ms, followed by a
<br>> blank screen for 1200 seconds (for a total of 1500 ms). The
<br>> participant needs to press the letter g if the word is neutral or do
<br>> nothing if the word is emotive. Pressing the key should log a
<br>> response time, but should not end the stimulus event (i.e. the
<br>> stimulus+blank screen will always run for 1500 ms even if the
<br>> participant responds within the first 300 ms). The participant can
<br>> respond anytime throughout that 1500 msec. I understand this is
<br>> called "extended input" - which I have accounted for by making the
<br>> time limit>duration.
<br>>
<br>> My biggest problem that I noticed is that my RESP Acc is coming back
<br>> as 0 when the correct action is to do nothing, and the person has
<br>> not pressed any key. Do you know why this is?
<br>>
<br>> I have uploaded a simple example file showing just 4 practice
<br>> trials. If someone who is experienced could take a look at it it
<br>> would be much appreciated - I am all alone in my department working
<br>> with e-prime and there is noone to really talk to here [Ermm]
<br>>
<br>> ===================
<br>>
<br>> P.S. I tried to attach the file here but it was giving me issues...
<br>>
<br>> Many thanks again!
