Creating blocks
Hello everybody!
I am doing a Flanker experiment, and I have 18 unique trials which has to be repeated 8 times.
Now I want to separate the experiment into 2 blocks. I have really no idea how to do this, I've searched the internet for a very long time now and I'm still lost.
Can somebody help me? You can see my overview (screenshot).
Thank you in advance!

Hi Anne,
How about, you only repeat the 18 trials 4 times, but wrap another Loop/Sequence structure around the trial loop and set its repeat value to 2?
Does that make sense?

Thanks for the quick response!
I don't think I am allowed to do that. I have to do this experiment for my study and my teacher wants us to use blocks. I have to download a screenshot of my overview, so they can see I've used two blocks. Is it hard to do it that way?

Maybe I am not understanding it right, but your sequence suggest that you have only a single block of 128 trials. while I propose having two blocks with 64 trials each. Isn't that what you want?
Yes, I currently have only a single block. I have in total 144 trials (18 unique trials x 8 repeat), now I have to separate them in 2 blocks with 72 trials each so that the person who does the experiment can keep their concentration. Does that make more sense?
@eduard
What I suggest does exactly that. See the attached experiment for an example of the structure that you want.
Thank you very much! Very helpful
