Hi,
I have a question regarding programming fMRI experiments. I am programming a source memory experiment and would like to do ROC modeling with the data. Therefore, I would need to record two responses from participants in each test trial (i.e., Red, Blue, New; and 1, 2, 3). I am wondering if it's fine to do that in the scanner. I used Optseq2 to randomize the trials and have accounted for the total amount of time I would need to get both responses (8 sec/trial -- 4 for each response). I just wanted to make sure that's the right approach before testing participants on the task.
Thanks, Christie
