Hi,

Thanks for all of the clear information, but please paste in code as text into your message. We can’t cut and paste from your code if it is in a screen shot, and please:

Please surround python code with backticks

When you include python code on this forum please put triple “backticks” like this ``` on the line before and the line after your code. If you’ve done it correctly then your code will appear in a grey box with correct indentation like this (check the preview of your post on the right hand side before posting it) and other people will be better able to work out what might be right/wrong with your code. if myVal==True: break If you’ve already posted something that didn’t follow this rule th…

Having said that, you are on the right track with your code but note that you are running it conditionally (only on the first trial), so it will have no effect on subsequent trials. 80% of the time, the stimulus would be set to be invisible, and remain so for the rest of the experiment.

But there is a larger problem here. Rather than do this within one routine, you probably want to split things across routines (i.e. construct your trial from multiple routines), and make the execution of those routines conditional on your popup_prompt_rng variable.

The reason for this is that you can’t have two keyboard components running at the same time, as you have currently. There is only one physical keyboard, so they will be competing and conflicting.

So put your popup message and keyboard on a separate routine, with the message text set to always be visible. Insert a code component on that routine, and generate your popup_prompt_rng variable.

Then add this:

# only run this routine on 1/5 trials:
if popup_prompt_rng != 1:
    continueRoutine = False

If you need the stimuli (e.g. the math problem) from the previous routine to carry over to this one (so the participant doesn’t notice the change), you can do that. Just insert another text component, and carry over its content from the previous routine.

EDIT: actually, looking at your screen shots again, maybe this wouldn’t work for you, as you want that prompt text to appear early in the trial. So just remove the conditional line about .thisN == 0: from your code, and adjust things so that you can just use one keyboard component, to avoid the conflict between them overlapping.
