Making different subgroups inside a block loop on a math problem verification task
I have designed a math problem verification task in OpenSesame, and I would like to make a slight modification, although I am not sure how to go about implementing it. It goes as follows:
My math PVT includes additions and subtractions (12 items for each block total—6 and 6) and 7 blocks of ascending difficulty. I would like the items to be presented based on operation type (e.g., 6 additions, followed by 6 subtractions, and vice versa), but the order of items within the 6 additions and 6 subtractions, as well as which operation group is presented first and which second within each block to be randomized.
I understand that it might be a bit confusing, so I am willing to provide any further information to make it clearer. Any kind of help would be greatly appreciated! Thank you!
