No subject

you might try adding an additional List object at the end of your program.  keep a running tally using in line scripts each time you get an anticipatory response, then populate the list at the end of your program with as many repeat trials as you need.

so you'd have an in line script like this after each stimulus to which the subject must respond:

Dim anticipatoryResponse As Integer

If TextDisplay.RT <= 200 Then
    anticipatoryResponse = anticipatoryResponse + 1
End If

and then after all your trials have initially been run, you add the necessary number of repeat trials to the last list (let's call it RepeatList):

RepeatList.SetWeight "1", "anticipatoryResponse"

something like that ought to work.

i think.

Hi,

I have a question about stopping trials that are re-run from being 
overwritten. I would like to re-run trials that are anticipatory 
(response time is less than 200 ms) but do not want that trial data 
to be overwritten. So I'd like to log the data for both the 
anticipatory trial and the trial the will be re-run after it. If 
anyone has a suggestion as to how to do this, it would be greatly 
appreciated.

Thanks, Kara.
