Okay. I have solved the alternating presentation location:
In my inner lope, I had two columns with baseLoc (the baseline option) and altLoc (the alternative option). In those columns, I alternate left and right.
Then, in the routine before, I added a code snippet. Tip: make sure this routine is inside the loop with your excel sheet.
if baseLoc == ‘right’:
base_effl_loc = [-0.5,0]
base_rewl_loc = [-0.2, 0]
elif baseLoc == ‘left’:
base_effl_loc = [0.5,0]
base_rewl_loc = [0.2, 0]
if altLoc == ‘right’:
alt_effl_loc = [-0.5,0]
alt_rewl_loc = [-0.2, 0]
elif altLoc == ‘left’:
alt_effl_loc = [0.5,0]
alt_rewl_loc = [0.2, 0]
Then, in the image component for my 4 images, I put in the name in location part. So $base_effl_loc for baseline effort image etc.
It works like a charm! Now onto my next problem
