Hi,
I’ve created a dot probe task where two images appear, one on the right side and one on the left side, and following the images, the letter E or the letter F appears on either side of the screen.
Is there a way to limit how many times the same letter appears in a row? For example, I want to limit the amount of times that ‘E’ appears in a row to just 3.
Additionally, is there a way to limit how many times the probe appears on the left/right side?
Thank you.

Hi @Mai_ta,
assuming that you have a conditions file that specifies where which probe should appear (e.g., columns pos
and probe
), you could set the loop to full random and number of repeats very high. This way you can then skip trials that don’t match your criteria. Then you could check some conditions at the start of each trial using some code:
Begin experiment
last_pos = "none"
last_probe = "none"
same_pos = 0
same_probe = 0
Begin routine
if NameOfYourLoop.thisN == NumberOfTrialsYouNeed: # needs to be adjusted to your needs
NameOfYourLoop.finished = True # needs to be adjusted to your needs
if last_pos == pos:
same_pos += 1
else:
same_pos = 0
if last_probe == probe:
same_probe += 1
else:
same_probe = 0
last_pos = pos
last_probe = probe
if same_pos > 2 or same_probe > 2:
continueRoutine = False

Thank you so much!
It’s not entirely working yet but I think I need to make a few changes first.
