How to represent an identical random experimental session (case 3490)

[jarvis]

Mmm. Those randomization functions don't have a without replacement option like you get with the use of stim files. That makes me wonder if you colud simply enter the stimuli into stim lists and draw them from there randomly without replacement? You could also repeat the stimuli that are selected if you need to. I'm guessing the sessions are not back to back? That would be great because you could use the "repeat" stimulus function to create the duplicate task. Limit is that it only works within the current session, so you need to have both subjects particpating as if they were one.

And the sample with elaborated instructions:

But yes, transforming log files into input files is certainly also an option--a fairly basic text manipulation routine or an Excel macro could probably take care of that. Before getting into that though, is stimlist functionality of possible use? And do you or anyone you know have any basic programming skils? If so, I could give you some direction in transforming the log files.

What we are currently using is the stimlist feature; however, the sessions are not back-to-back, so that wouldn't be useful for the time two session (in which the participant should have an identical experience as time one).

As to manipulating the log files, I believe I could program myself given a bit of instruction.

What method of programming do you like to use? Do you know VB? It's nice and quick for text manipulation.

I haven't used VB, I've done some HTML / Java programing in the past...If VB is similar than I should be able to tackle it. However, do you have an example of transposing a log file to a new input file?

Hi gh0strider18!

Just checking to see if you needed any help with this programming or if you had figured something out.
