Hi Amie,
The tutorial is indeed a bit confusing. What it meant to say is that different stimuli can be allocated to the same location, but each of them will nevertheless occupy a different space (within that location). We can review whether this is a reasonable behavior. Maybe it isn't.
The most efficient way to code up your study might have to involve using an external tool - perhaps it's easier to create a "movie" for each presentation sequence? It sounds like the sequences (under all three variations) are hard coded anyway. One can probably do it in PowerPoint by creating a sequence of slides that present the entire sequences of stimuli, and then export it as a video file. You can then upload the video files to FF and just create a single "trial" for each movie, with a background audio attached to it.
Alternatively -
Will the ability to mix trials between blocks on FF solve your issue as well? The way I see it, you can create yoked trials for each sequence, put them into three blocks, and then mix up the blocks? We are interested in developing this feature, since it will likely come up again in other researchers' designs.
Let us know!
