Hello there, I’m trying to design a Posner Cueing experiment, and to randomize the inter-trial intervals, I have been using a cross polygon component with the stop time defined as random() + 1 in the polygon properties GUI, so that it can give me a number between 1 and 2 each trial. However, since I’ve updated PsychoPy to 2020.2.6., it gives me the error “Variable name random is in use (by numpy function). Try another name”, below the properties window, in red text. When I try with $, it gives me the same error. It has worked before the update, and now, I can’t randomize the duration of the initial segment. I would greatly appreciate any help with this problem.
