![]() ![]() random = randint(1,7)Ĭreating empty current variables to determine what item in a variable list is presented each routine. The counterbalances are repeated to cover every possible iteration of the 3 instructions, 3 stimuli subsets, and 2 lists per subset.Ĭounterbalancing which of the 2 lists in a stimulus subset are the presentation item random = randint(1,3)Ĭounterbalancing the order of the subjects go through the stimuli subset. One thing that does worry me is if the multiple layers of conditional statements of append or push commands is somehow causing difficulties. There is never a crash in the counterbalancing block, but I will include some code as further context. There are images that repeat in the excel file as part of the test attempts. All images are in nested folders within that folder (a separate folder for filler and presentation images). The excel file is in the same folder as the PsychoPy build. face_p1a.append(p1a)įor context, here is part of the excel file. face_p1a = Īt the start of the same routine, I then add on the images from an excel file. To avoid ambiguity, I am going to include a fair bit code.Īt the beginning of the experiment, I create several empty variables to add things too. All image files currently used and tested are PNGs. I am having trouble identifying the difference that is the source of the problem. ![]() Notably, the filler task is also image based, and those images are working fine. The part that is proving difficult is incorporating the presentation images into PsychoPy. There is then a filler task and then a recognition test with the 15 presented (old) faces and 15 new faces. ![]() Each subset consists of 2 lists of 15 faces, one of which is randomly assigned to be presented. Each block is randomly assigned and counterbalanced to 1 of 3 instruction conditions and 1 of 3 subsets of face stimuli. Subjects complete 3 blocks of a facial recognition task. If not then just delete and start from scratch. ![]()
