Wrong RT recorded?

Builder

Hi,
I’m in windows 10, use the builder.

First, the experiment starts with some simple questions:

Here is the output of two of these questions: In the first trial starting in column AJ, we see a very high key_resp.rt (column AM) while for the second it is super slow (column AT). I def did not press the button very quickly on the second question. How come?

Here is the link to the csv file: data - Google Drive

Below, the slider.rt (column BI) is very low and negative. I probably should ignore this column and rather look at column BM to get the RT?

For information, I use the slider with a mouse response.

In the ‘Begin Routine’ I define that there are no ticks (somehow I think that the problem might be linked to this) and that the labels are changing based on the question (randomized presentation).

Thank you very much!

Nobody knows? Anyone met the problem before that the RT are so low (column AT and BI)?
Is the question well enough written or should I try to improve the post?

Hello

Which PsychoPy-version are you using? There was a bug in some PsychoPy-versions, see here.

ok, I found the error. It is not a problem with saving correct RTs but with a comma separation of the input stimulus file. the problem is discussed here but no solution found: Online experiment saved data was format misplacement - #17 by Stuart_Furnell
