Hi,
I am trying to design the following task, and am not sure about the best way to proceed.
I have a scrambled letter task where participants are presented with a string of letters and have to find as many different word combinations out of the letters as they can. I want participants to be able to see the responses they already entered, and also to be able to go back and forth between puzzles as they wish (i.e. they will have 10 minutes to solve as many as they can, but they can go back and forth between puzzles). I am guessing I can do this with custom items, but the difficulty is that I also need, either as participants move from puzzle to puzzle, or at random intervals as they are doing them, to have a prime briefly flash on the screen. I am not sure whether I could do that with custom items. Perhaps I could somehow do it with DirectRT?

Thank you for any suggestions you may have.

Marina
