Sorry I made a mistake in the last post, but I can’t edit it.
I now realise that I should have used a .log in the newText(“q”, row[‘Q’+n_question]) command, to have the direct timestamp of when the question appeared (but i didn’t and I already collected data). And I understand that I was incorrectly interpreting the timestamps in the solution I proposed above.
I’m sure, though, that there must be a way to calculate the time between the moment that the dashed-sentence controler ended (and the text with the question appared) and the moment when the participants pressed the Arrow key with the data I have. But I don’t understand what the timestamp reported in the dashed sentence means, is it when it started ot when it ended?
Here is a more complete sample of my results.

I’m really sorry for the confusion and the multiple questions but I’m confused about the timestamps and I can’t find the information in the documentation files.
Thank you so much!
