Psychopy Version 1.84.2 on mac. We are trying to program a local-global task. In total we will use 6 different displays that differ in local-global features. Using the polygon component we managed to create all displays and currently we can present each display block-wise but we want to present the different displays randomly across trials. Since each display type requires different number of polygon component in a given trial, it is not possible to create a variable in the condition file. Is there a way to present different displays in trial-wise order?
