OS (e.g. Win10): Windows 10
PsychoPy version (e.g. 1.84.x): 1.85.2
Standard Standalone? (y/n) If not then what?: Yes
What are you trying to achieve?: I am creating a flicker paradigm where an image (image1) is displayed for 500 ms followed by a blank for 250ms and then another image (image2) for 500ms. Hence, I would like a continuous loop of image1, blank, image2, blank, etc. which stops until the spacebar is pressed.
What did you try to make it work?: I have put the two images in a .xlsx, used a $ to link them and ‘set every repeat’ is selected.
What specifically went wrong when you tried that?: When running the experiment, image1 appears for 500ms followed by the 250ms blank and then image1 is displayed again for 500ms immediately followed by image2 for 500ms, a 250ms blank and then image2.
I would greatly appreciate if someone could provide advice on how to display image1, blank, image2, blank, etc.
Also, is it possible to make this loop occur infinitely until the spacebar is pressed and how should I terminate this loop when the spacebar is pressed?
