null response question

[Maxfield]

I'm running a go/nogo task, and would like Eprime to score accuracy
(ACC) as it usually does. Things are working just fine for my "go"
trials. However, I'm running into a problem on "nogo" trials. Since
no response is logged (no button press), I have included zeros in my
"correct response" column, but Eprime scores these as error trials.
I've also tried leaving the "correct answer" cells blank for "nogo"
trials, but the outcome is the same. Any advice on how I can get
Eprime to treat correct "nogo" trials (null responses) as correct?

Thanks in advance,
Nathan from Tampa

Are you sure you left it blank and not " "? I've done it before and it's worked
fine. I can send you the script if you'd like.

Hi Chris,
I noticed you were helping Maxfield with programming E-prime to make
no response the correct response. Just to make sure I have this right:
If you leave "Correct Response" blank, it will recognize that no
response is correct and any other key press will be considered
incorrect? Also, the same goes if I'm loading the correct response
from a column in text file? That is, I just leave the cell blank?
Thanks

I've encountered the same problem, trying to define 'no response' as
the correct response (and any other response as an error). Does anyone
have a suggestion? I'd really appreciate it.

Thanks!
