URL of experiment: Dual_task [PsychoPy] (Not sure if it will work as its in Pilot mode currently) Description of the problem: The error pops up following instructions, so when the stimuli are supposed to appear. I’ve looked through previous posts with this error but cannot seem to find a solution …

Just to close this - I figured out the issue! The array issue was arising from the Excel conditions sheet we used to set position and colour. Changing the colours from arrays to just the names of the colour sorted that issue! There was another unrelated issue which was an easy fix. Thank you Jens…
