Recorded RT greater than trial_duration

[marton-balazs-kovacs]

Hi All,

I have one modified Stroop and one prime probe task where I use a calibration phase to calculate a deadline for responses during the test phase. The deadline is added to the test phase in the on_start event.

I have collected a lot of data and in most of the cases, the RT is smaller than the trial duration. However, in a few instances, the RT is greater than the trial_duration. In the most extreme case with more than 1 second.

Do you have any tips on how is this possible?

When I look at these strange instances I do not see any particular pattern.

I tried to reproduce this result using my computer and running it on localhost (I used jatos for data collection), but I could not get the rt higher than the trial_duration. It would be important to know the source of the mistakes since a great proportion of the trials during the test phase were timeouts.

Here is the code that I used:

Best,
Marton

Hi @marton-balazs-kovacs

Are you using a custom plugin to run any of these tasks?

Hi @jodeleeuw,

I was using JATOS to collect the data.
