Hi Gugs,<br><br>a quick first thought: did you indicate the correct response to be "" (e.g. nothing between " 's) for the trials in which 'nothing' is the correct response?<br><br>On Wednesday, 5 December 2012 02:55:23 UTC+1, gugs wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Hi All,<br>I posted a query on the e-prime discussion forum last week
but haven't had any replies yet. The main issue I am having in
programming a go/no-go task is that the acc column is incorrectly
returning a 0 when the answer is correct (but only for cases where an
individual should not be responding to the stimulus). <br><br>I have
posted the detail here:
<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 them
here as well in case someone has an idea of how to correct this. David -
I know you are generally answered a lot of go/no-go extended input type
queries so I was hoping you might know.<br><br>===============<br><br><span><span><span><span><span>The
task is fairly simple - an either emotive (i.e. happy, sad) or neutral
word will appear on the screen for 300 ms, followed by a blank screen
for 1200 seconds (for a total of 1500 ms). The participant needs to
press the letter g if the word is neutral or do nothing if the word is
emotive. Pressing the key should log a response time, but should not
end the stimulus event (i.e. the stimulus+blank screen will always run
for 1500 ms even if the participant responds within the first 300 ms).
The participant can respond anytime throughout that 1500 msec. I
understand this is called "extended input" - which I have accounted for
by making the time limit>duration.<br>
<br>
My biggest problem that I noticed is that my RESP Acc is coming back as 0
when the correct action is to do nothing, and the person has not
pressed any key. Do you know why this is?<br>
<br>
I have uploaded a simple example file showing just 4 practice trials.
If someone who is experienced could take a look at it it would be much
appreciated - I am all alone in my department working with e-prime and
there is noone to really talk to here <img src="http://www.pstnet.com/forum/Skins/Classic/Images/EmotIcons/Ermm.gif" title="Ermm" align="absmiddle" border="0"></span></span></span></span></span><br><br>===================<br><br>P.S. I tried to attach the file here but it was giving me issues...<br><br>Many thanks again!<br><br></blockquote>
