Perception Tasks Randomization

[Avichai_Bachar]

Hello,
I’ve created 3 perception tasks as part of my experiment (as seen in the attached picture). The problem is that I would like them to be presented randomly but I don’t know how to do this. I know that I have to create a bigger loop that encompasses them all, but I don’t know what to set in it’s properties and what information to insert in the excel file. I would like to get some help.
Thank you very much!

Have a look at this post for a commonly recommended approach.

Randomizaing Loops

System: macOS Version 11.5.1 Psychopy version: v2023.2.3 I am designing a study where participants will be presented with four conditions, and 18 randomized sentences will be presented in each condition. As shown in the screenshots, I want to randomize the four loops without mixing any conditions within. In that case, only HigherKey, LowerKey, Instrumental and Control will be randomized, but not the sentences between conditions. I have three loops here, the most inner one is a loop to show …

Thanks for your comment.
I followed the instructions, and it went well until I created the outer loop. I gave the columns in the excel file the names of the inner loops but the program doesn’t launch the experiment and exits with code 0. Print screen is attached.

Exit code 0 means no errors.

Please could you show one of your inner loops and the spreadsheet you use for your outer loop?

Properties of one of the inner loops:

Spreadsheet of the outer loop:

Change Num repeats of SIN_Trial to SIN_Trial (your spreadsheet column) and change the name of the loop to, e.g. SIN_Loop

Repeat for your other inner loops

It works! Thank you my friend, you helped me a lot!
