I’m wondering how I can have 3 different sizes for my image stimuli. I have 3 different images per trial, all presented simultaneously and horizontally on the screen (in a row). I would like each image to have 3 different sizes, all of which will be randomly chosen per each trial.
On my trial routine, I have 3 image components, each represented the left, middle, and right image in the row.
Thanks so much in advance!
you can use variables for width and height of each image-component and set the parameter to set every repeat
For example in the Begin routine tab (you might need to initalize the variables when running the experiment online:
width = [0.1, 0.15, 0.2]
height = [0.1, 0.15, 0.2]
width1 = width.pop()
width2 = width.pop()
width3 = width.pop()
height1 = height.pop()
height2 = height.pop()
height3 = height.pop()
Note that this approach randomises width and height independently. I have chosen arbitrary numbers for width and height. You should adapt them for your purpose.

Hi Jens, thank you so much for your input. This has worked!
