I need some ideas. I have exhausted all avenues and can’t find a topic or YouTube tutorial that will help. (If you have any words that might clarify my search, I am all ears!) I am currently developing an experiment in PsychoPy that involves multiple complex elements, and while some parts are funct…

Do you know about my online demos post? Independent randomisation might be useful. [image] PsychoPy Online Demos Blog If you have routines or experiments that are likely to be useful to others, please create a post in this thread, editing your post to add new demos so the…

Yes, I am aware and heard of them but unsure which component/parts would apply to me. I will check it out though. Thank you!

[image] Hans: Set up: Using an inner loop to randomize 75 decisions for high effort/high reward conditions (so vary effort 2-6 and reward 2-6 separately). Your initial post contains too much to addess. Let’s start from the top. Do you want independent randomisation of effort and reward condi…

Hi. I have this set up. With an inner loop set to random with an Excel sheet with 75 decisions (so RewardLevel = 1,2,3… so on, EffortLevel = 1,2…so on with all possible combinations). I think this will work. Do you think so? I am concerned that it will cause: the two loops interfering with each o…

If you have 75 passages which you want to randomly allocate the to the 25 combinations of effort and reward then we are back to independent randomisation. See Independent Randomisation but you might like to also look at Trial Switching or PsychoPy Code Component Snippets - Google Docs for the code …

Yes, but the probelm is I only have 65 passages and I don’t want them to read all of those passages. Only 8 of them. But there is a possible 65 passages that they may read (depending also on thier decisions. If that makes sense. I will have a look at the Google doc (I think I’ve used it before) and…

So do you want 8 of the 65 passages to be read in 8 of the 25 effort/reward combinations? If so, you could break the trials look when you hit 8 if trials.thisN == 7: trials.finished = True

Hmmm. That could work. I want to read 8 (of the 65 passages) in 8 of the 75 decisions (which could be done by 3x25 effort/reward combinations). Would that work similar?

Why 8 of 75 and not 8 of 25? Surely you don’t want to risk getting repetitions of the same effort/reward combinations? Personally I’m surprised that you aren’t using 9 passages and displaying 3 levels of reward x 3 levels of effort to give a complete factorial design.

Hi. Yes, I need repetitions. 75 decisions are the norm in this effort discounting paradigm, so I am working with that (since the more decision data I get, the better). The execution of the passages isn’t as important as we are just teaching the kids that their decisions matter (which is why I want i…
