Win10, PsychoPy version 2022.2.5 Hello everybody :slight_smile: I hope you are doing well. I’m currently preparing an experiment for a dissertation. I’m building a free recall task. There will be 3 conditions (positive, negative and neutral emotions) My participants will have to study in each c…

Hello the following toy-experiment presents numbers from 1-60 in four blocks, 1-15, 16-30, 31-45, 46-60 in random order. Here is the flow [grafik] In new block, create a code-component with the following content in the Begin Experiment tab: useRows = '0:1' wordList = ['0:15','15:30','30:45','45…

Thank you Jens for your quick reply, I will try this!!!

Good morning Jens, I tried what you suggested but unfortunately it didn’t work [image] This is my excel file with my list of words, should i change anything ?

Hello, what do you mean with [image] Emeline_Fhr: I tried what you suggested but unfortunately it didn’t work It looks like you arranged your lists in wide format. The apporach I suggested expects the lists in long format. Best wishes Jens

Is there a way to do the randomisation with wide format or do I need to put in long format ? many thanks

Dear Jens Here is the message error I get : “‘NoneType’ object is not iterable” So I believe I have a problem with a variable. Could you kindly me explain me more about useRows and wordList ? I believe I have a problem here Thank you for your time.

Hello Did you try to rebuild the experiment I describe above? The error message tells you that you try to iterate an object that is not iterable. A good source to learn about PsychoPy is: Peirce, J. W., Hirst, R. J. & MacAskill, M. R. (2022). Building Experiments in PsychoPy. 2nd Edn London: Sage. …

Dear Jens, I had a mistake in my own wordList variable, I used words instead of numerical values… I did’nt understand properly your explanation, my bad!!! Everything is now working, thank you so much for your time and your help. Best wishes!

Hello,

This is much easier to achieve in the long format than in the wide format. It is some copy&paste work.

Best wishes Jens
