Hi,
I’m programming a task about presenting two images in the same moment on the screen, because my participants must calcule areas from the stimuli. In this way, for each trial I want to repleace my stimili according the next propouse: my first image must be in the left side and my second image must be in the right side at the same moment. Then, to the next trial my my first Image must be in the right side and my second image must be in the left side.
In adition, I have eight stimuli in the conditions’ sheet. They must be chosen randomly and counterbalancing randomly too for each trail.
I don’t know how to code it or state it into a spreadsheet of Excel. Does anyone have an idea how to achieve it, I was wondering if you help me.
