I have a number of instruction screens with text stimulus. They are set to only end when the P makes the correct response. However they sometimes (but not always) go blank after some time (the time varies). They do not move on to the next event, they just go blank.
I have attached the experiment below. I cannot say if it happens with every text screen as it is intermittent, but it definitely happens with both the first and second events.
On one of the events I set it so that the event was over either 1) after a correct response or 2) after a time limit (a really long time) to see if this would help but it did not.
