cut experiment into different block
Hi, I have a question about cutting the experiment into several block.
My experiment will has 192 trial (2*2*4*4= 64 full factor design). So if I want to present each combination， each block will contain 64 trial. But I want to make each block only contain 32 tiral, is anyway to achieve that （in the case, 2 block should contain all combination）？
I know I can add an inline scrip to count the trail and present a break after 32 trial. But this way is a little bit complicated. If anyone have another way to divided the experiment into different block, wish you can share it with me, thank you very much!

Hi,
You could "fake-split" your blocks. Just add a "pause" sketchpad at the end of the block, that will only be shown if the trial count is 33 or something like that. Set the duration of the pause to 20 seconds or so, so that participants actually have a break, and then continue with a mouse response/button press (ideally something that won't interfere with the rest of the experiment.
Does that help?
