So the screen is either supposed to show a stimulus (one of several shapes) or a fixation cross which looks like: +
Sometimes when changing from one to the other the screen is blank for too long - other times it changes instantly from the shape to + or + to a shape. I’m wondering if there is anything I can do to prevent that.
By “preloading” stimuli I mean that each image is set during a previous constant period - usually a period that contains + since everything during that time is constant.
I used code components as well as editing the .py file directly. The only edits to the .py file directly were to add in lines to record onset and offset times of stimuli. I couldn’t figure out how to use the code component to do that and was able to do that in the .py file much more easily. This issue of the screen being blank for too long occurs when I run the .psyexp file, not just the .py file.
Let me know if you need any other clarification! Apologies for the short/confusing post earlier.
