repeat practice trials after incorrect response

[jenjordan75]

I ran into the same problem with trying to backwards jump trials. I wish this were possible - esp. when you want subjects to be able to repeat the trial as many times as is necessary to submit the correct answer. Theoretically, you could just keep inserting identical trials, one after the other, but there is also a limit to how many trials direct RT can hold (99, I think?). [nope--editor's note see below]

But simply inserting identical trials does work.

One question for Jarvis24. What does the "!" after the "2" mean? I am unclear what "rt:57>2!,43", as opposed to just "rt:57>2,43" would do. [yikes! see editor's note see below]

OK, that's really weird. I don't know why I would have written it that way above (i.e. using the ! symbol). Unless I'm too tired to be thinking about this, I'm sure it should be rt:57>-2,43 if you want to jump out of the trial immediately on the pressing of the spacebar (as opposed to waiting until the whole trial is finished). I don't know where the ! came from. It may be that at one point I considered that as a possible syntax for the function. In any case, I don't think it would have any such power if you were to try it. And hey, if you do try it, let me know!

Also, just a note of clarification. There is a limit in DirectRT of 99, but it's a limit on the number of stimuli within a single trial, not a limit on the number of trials. I'm sure that's what you meant, but I wanted to be super clear for the sake of all those following along at home
