Hi! I ran my experiment and everything is fine while running but when I check the csv, it has some blank cells when stimuli stopped. It happens with all my stimuli (I have 6) in 22/52 essays. I would like to figure why it happens in case it can be avoid.

I upload the csv in case I was’t clear.

Any commentary is welcoming!

How are you saving the data?
I don’t think I understand the CSV file you sent. it includes only 1 row of data, which is mostly empty.
Would you mind explaining or including your study?
Thanks

I’ll leave the correct csv and the experiment in case you need it.

Thank you!!!

Hello,
The empty cells in your experiments are scenarios where the participant pressed the space button before the polygon stopped.
So whenever you have a timestamp for the current stopped polygon, it means the polygon stopped before the participant pressed the space button.

I replicated it in this simple experiment:
r.psyexp (8.8 KB)
No data = Click space before the polygon disappears.
Data = Click space after the polygon disappears.

Essientely, the offset time of the polygon should be equal to the moment the participant presses the space button.

Now that you know what the issue is, you can try to find a way to fix it, if even necessary.
Let me know if you need help :slight_smile:
