I want to present some pictures to one group of subjects while presenting different pictures to another group of subjects. I have no idea how to manipulate a between-subject variable in one experiment procedure. Any tips or suggestions would be appreciated. Thanks sincerely.
Best wishes, Cheer.
One way of doing it is to point at different Excel files. For example:
conditions =‘conditions2.xlsx’ if int(expInfo[‘participant’])%2==1: conditions =‘conditions1.xldx’
